The Missouri Muhlenbergias. BY BENJAMIN FRANKLIN BUSH. Any one in recent years attempting to name specimens of MUHLENBERGIA by the books, must have been struck by the wide difference of opinion in the presentation of the species in the Robinson and Fernald Gray’s New Manual, and the Britton and Brown Illustrated Flora. This difference of cpinion in treating the species of this genus in some cases is so marked as to cause one to wonder if there is not something wrong with our understanding of the species. This difference of opinion is most marked with the members of the Mexicana group, a most perplexing and critical one, the species of which present so many variations in culms, leaves and floral characters. _ It was formerly thought that the species of this, and those of the Acroxts group, were either awned or awnless, this belief causing much confusion in the treatment of the species and the naming of specimens: but it began to be suspected that those species which were habitually awnless sometimes presented awned forms, and those species that were ordinarily awned, sometimes presented awnless forms. This suspicion was first voiced by Scribner,’ who announced that M. Merxicana and M. SOBOLIFERA often or occasionally presented awned forms, and he went so far as to describe awned forms of these species,? and noted that M. TENUI- FLORA and M. TorRreryi were occasionally awnless. My conclusions after a careful examination of several hundred sheets of specimens, are, that Scribner was correct in the main, but that what he took to be awned forms or varieties of M. MEXICANA and M. SOBOLIFERA are really good distinct species, which I herein propose as new. * Scribner, Rhodora 9:18. 1907. ? Scribner, Rhodora 9:18. 1907. os THE AMERICAN MIDLAND NATURALIST Hitchcock '|in the Robinson and Fernald Gray’s New Manual in 1908, presented ten species and one variety for the territory commonly embraced in the Manual region, presenting M. FoLIosA Trinius, for the first time, this having been previously restored by Scribner,? and to it he referred M. ampicua Torrey, which I am inclined to think is a good species. M. Mexicana is there said to have the culms retrorsely strigose below the nodes, and to have the lemmas acuminate or awned, thus including the M. MExIcaNna COMMUTATA of Scribner in his description. It appears to me much better to consider Scribner’s variety a distinct species, and thus relieve the real M. Mexicana of much uncertainty. Hitchcock also includes M. poLystacHya of Mackenzie and Bush in M. MeExIcANA, which after.an examination of a number of specimens I still consider distinct from that species. He reduces M. PALUSTRIS to a variety of M. SCHREBERI, a disposition once made by Scribner,’ but it seems more natural to keep this distinct from that species. The description of M. SCHREBERI is so drawn as to include M. SCHREBERI CURTISETOSA of Scribner, which seems to me to be sufficiently distinct to recognize as a species. M. GLABRIFLORA of Scribner is not mentioned in the Manual, Hitchcock evidently not understanding this species. Nash in the Britton and Brown Illustrated Flora, second edition, in 1913, presents eleven species, ten of these given by Hitchcock in the Manual, and one other; M. ampicua Torrey. In the treat- ment of the species in this work, Nash gives specific rank to M. PALUSTRIS and M. amMBiGuaA, refers M. FoLIosa of Trinius to M. MEXICANA, ignores M. poLysTacHyA of Mackenzie and Bush, and M. SCHREBERI CURTISETOSA, and briefly mentions M. GLABRI- FLORA which seems to me to be an excellent species. In his description of the MExIcANA group, Nash does not speak of the retrorsely scabrous character of the culms just below the nodes of some of the species, evidently thinking this character not worthy of mention. Many years: ago Prof. Dewey wrote the account of the Grasses for the Manual of the Plants of Western Texas,3 in which the ranges of some of our species is given, no doubt based on-specimens in the Herbarium of the Department of Agriculture. The ranges given of several of our species in this work has been modified largely by ’ Scribner, Rhodora 9:18. 1907. * Scribner, Rhodora 9:18. 1907. > Dewey, Man. of the Plants of Western Texas, 1892. MISSOURI MUHLENBERGIAS | 19 numerous collections and critical study of several species. Prior to 1905, several of the species now included in the genus MUHLEN- BERGIA, were included in the genus Sporobolus, when Dr. Rydberg’ transferred some of the species to this genus. These species seem to me to be intermediate between MUHLENBERGIA and Sporobolus, and could with equal propriety be included in the genus Sporobolus or in MUHLENBERGIA, but I leave these species in MUHLENBERGIA as placed there by Dr. Rydberg. But there is a group of species having single, terminal panicles with flowers on long capillary pedicels, the type of which is Stipa capillaris Lamarck, that seems to me to be very distinct from the other species commonly included in the genus MUHLENBERGIA. This group of species is so distinct from the other species of MUHLENBERGIA in rootstocks, ligules, panicles, flowers and habit, that I think there is no doubt that they are certainly distinct from that genus. The earliest available name for this group of species seems to be PoposEMuMm Des- vaux, in Nouv. Bull. Soc. Philom. 2:188. 1810, where the genus is established and Sizpa capzllaris Lamarck is cited’ as the type. The genus is more fully described in Beauvois Agrost. 29, 1812. I have therefore decided to follow Desvaux in placing some of the species formerly included in the genus MUHLENBERGIA in the genus PODOSEMUM, but present the single species occurring in the State along with the other species of MUHLENBERGIA, to which it has generally been referred. In this, my presentation of the Missouri species, I differ some- what from the treatment of both Hitchcock and Nash, in the works mentioned above, and have more nearly agreed with Scribner in recognizing the species, and have been compelled to describe one new species, being unable to refer the uso tn to any de- scribed species. I have seen nearly all the Missouri material in existence of the species of MUHLENBERGIA, through the kindness of Dr. J. M. Greenman, curator of the Missouri Botanical Garden Herbarium, Prof. A. S. Hitchcock, Agrostologist in charge of the Grasses in the United States National Museum Herbarium, Prof. Wm. Trelease cf the University of Illinois, Dr. J. A. Nieuwland of the University of Notre Dame, and Mr. Kenneth K. Mackenzie of East Orange, New Jersey, to whom I am under many Oe t Rydberg, Bull. Torr. Club, 32:1905. 20 THE AMERICAN MIDLAND NATURALIST to Prof. Hitchcock and Dr. George T. Moore of the Missouri Botanical Garden, I am under obligations for numerous citations furnished and for verifications of publications; to all of the above I herein return thanks for the many courtesies extended. For the Missouri species now included, or were formerly included, in the genus MUHLENBERGIA, I offer the following: KEY TO THE MISSOURI MUHLENBERGIAS.

Differs from M. sobolifera in having shorter, much-branched culms, shorter and narrower leaves, shorter and denser panicles, longer and narrower florets which are awned. Was referred by Vasey to M. sylvatica, M. sylvatica, var., M. sobolifera, M. sobolifera var., and M. Wulldenovit. Scribner based M. sobolifera setigera on Reverchon’s 70 and 1054, referring to it also his No. 30, but gives neither dates not localities for the type specimens. Many years ago Reverchon sent to Dr. George Vasey of the Department of Agriculture, specimens of Grasses to be determined, and these were numbered from 1 up, usually marking ‘‘ Vasey”’ on his labels. The specimens of Muhlenbergia which I am referring to this new species, which he sent to be named, were reported by Vasey under five names, M. sylvatica, M. sylvattca var —, M. sobolifera, M. sobolifera var.—, and M. Wildenovii. Believing these to be distinct species and varieties, Reverchon numbered one 1049, another 1050 and so on up to 1054, these being the numbers given to these species and varieties.in his MS. list of Texas Plants. But the specimens sent to Dr. Vasey with numbers on the labels, and other numbers bearing the same numbers do not agree, and I feel confident that Reverchon used the same numbers over and over. I have seen several of Reverchon’s No. 70, supposedly part of the No. 70 sent to Vasey, and these are marked M. sylvatica var. —, presumably a MS. name of Vasey’s, but these do not appear to be the same as that examined by Scribner. I have also examined two sheets of specimens marked 30 by Reverchon, collected at Ferris, Texas, but these differ from the No. 30 examined by Vasey and Scribner, and cited by Scribner as belonging to his M. sobolifera setigera, in being short-awned. These Ferris specimens are named M. sobolifera var.—presumably a MS. name of Vasey’s, and the date of collection is stated as 1884 and 1888, while the one cited by Scribner is said to be dated 1885. One of the Ferris specimens is numbered 1665, which makes it apparent that Reverchon_sep- arated this variety from M. sobolifera, and assigned it a much later “number in his MS. list of Texas Plants. Having been intimately acquainted with Mr. Reverchon, I learned much about his numbering, the earlier collecting being numbered according to his MS. list, which was arranged in accord- 40 THE AMERICAN MIDILAND NATURALIST ance with his collecting. When Reverchon first began collecting plants in Texas, in the seventies, the first species he collected he listed as No. 1, the next No. 2, and so on up to about No. 1884, when I persuaded him to adopt the serial system of numbering, beginning with the last number in his MS. list, and giving each collection a different number. | According to this earlier method of numbering, every species bore the same number, no matter where and when collected, as for instance, M. sobolifera was No. 1052, and every collection of what he took to be M. sobolijera he gave that number to, no matter where it was collected, in 1878, 188c, 1882 or 1885. : I have also examined one sheet of Reverchon’s No. 1054, which is labeled M. Mexicana by Reverchon, cited by Scribner as part of the type of M. sobolifefa setigera, but this appears to me to be only M. Mexicana. It differs from M. sobolifera setigera in having the lower glumes acuminate and nearly as long as the lemma, the lemma merely acute or acutish and not awned.

Type specimens collected at Webb City, Missouri, Palmer 2734, September 20, 1909, specimens in the Herbarium of the Missouri Botanical Garden, sheet No. 757387. The species here proposed has been referred to M. Torrey: on the one hand and to M. tenuiflora on the other, but differs conspicuously from these species in being lower, more branched, in having more numerous leaves which are shorter and narrower, with but 7-9 principal nerves, in having numerous panicles, which are mostly - short-exserted, in having glabrous yellow polished infranodes and glabrous nodes. It is much nearer M. Mexicana, to which it bears a strong resemblance, but differs in having shorter and broader glumes, awned lemmas, and long-exserted panicles from the lower sheaths. 3 SPECIMENS EXAMINED: MISSOURI: / Golden City, Palmer 4575, October 6, 1913, M.

A large genus of 40 species or more, natives of America, com- prising those species with more or less open, large panicles, the branches of which are either drooping or spreading, pedicals slender or capillary, lemmas long-awned, or occasionally short-awned or awnless.t A single species occurs in our territory. *The center of abundance of PODOSEMUM species seems to be in Western Texas, to which region P. capillare does not appear to extend, it being the center of a group of three species belonging to the South Atlantic r: gion. In a subsequent paper I shall discuss some of the many allies of P. capillare. 04 THE AMERICAN MIDLAND NATURALIST 1. PODOSEMUM CAPILLARE (Lamarck) Desv. Nouv. Bull. Soc. Philom. 2: 188. 1810.
