■94 Muhlenbergia, Volume 6 



This species is referred to L. palustris as a synonym in 

 Watson's Bibliographical Index, and has been so placed by sub- 

 sequent writers. The original of the Linnaean species came 

 from swampy pastures of northern Europe. The only definite 

 things in the descriptions cited by Linnaeus are that the pedun- 

 cles are many flowered and the stipules lanceolate. In the Illus- 

 trated Flora it is described and figured as having a winged stem, 

 and the "peduncles generally about equaling the leaves." The 

 steins of L. Lanszivertii are not winged, and the combined length 

 of peduncle and inflorescence is considerably shorter than the 

 leaves. 



In 1894 Theodore G. White, in the Bulletin of the Torrey 

 Botanical Club, offered a revision of the genus, publishing as 

 new L. coriaceus, the type being Watson's no. 297, "found in 

 the Wahsatch Mountains, Utah; 5-6,000 feet altitude." He also 

 included a specimen collected in Oregon. 



We have several specimens of L. Lansszvertii from the 

 mountains west of Reno, all labeled L. coriacens, and last July I 

 found it on Slide mountain west of Washoe, at an elevation of 

 7500 feet, growing on moist banks near a mountain stream, in 

 rather tangled clumps, the stems two to two and a half feet long. 

 The full sized but not mature pods are glabrous, 5 cm. long, 

 9 mm. wide. The leaves on nearly all of these Slide mountain 

 specimens are narrower and more acute than in Kellogg's type 

 as figured, but some of the leaves of other specimens are broader 

 and not so pointed. 



Whether L. coriaceus can be held as distinct, I am not pre- 

 pared to state. Rydberg's 6152 from hills north of Salt Lake 

 City, which is in the type region of L. coriaceus, differs mainly 

 from our specimens in having thicker and broader leaflets, but 

 in form they agree very well with Kellogg's figure. I have a 

 specimen in my own collection, gathered about Lake Tahoe by 

 Mr. Robert L. Pendleton, which has narrower leaflets than any 

 of our Nevada specimens, showing that the species is variable in 

 this respect. An examination of the flowers from several plants 

 shows that the blade of the wing is 1 cm. long and 6mm. wide 

 across the middle. While Kellogg's characterization of oblong
