Q2 Muhlenbergia, Volume 6 



Apparently this plant has not heretofore been recorded as 

 occurring in America. But it has now undoubtedly come to 

 stay, and should have a place in our descriptive texts. While 

 the upper stem leaves are apparently perfoliate, they are not 

 really so, but are auricled, the lobes overlapping, causing the 

 perfoliate appearance. Linnaeus gives its habitat "in Persia, 

 Syria. 7 '

"The following species of Lathyrus was sent from Washoe 

 by Dr. Lanszweert. 



"Lathyrus Lamzwertii, (Kellogg.) Fig. 44. 



"Stem slender, acutely quadrangular and striate naked, be- 

 low; sparsely somewhat appressed pubescent above, ascending 

 one to two feet in height. 



"Leaflets three to four pairs, linear-oblanceolate, cuneate, 

 entire, sub-acute, mucronate, sub-sessile, opposite, five to seven- 

 nerved, sub-pubescent, lamina rather rigid, thin, veins promi- 

 nent, petiole sulcate, striate, angled, tendrils three-parted, pu- 

 bescence loosely appressed. Stipules semi-sagittate, linear-lan- 

 ceolate, sub-falcate, entire, very acute or nearly subulate pointed, 

 upper third sparsely pubescent, ciliate, nerved. 



"Peduncles shorter than the leaves (one to two inches long), 

 angled, one to four flowered, flowers pale flesh-colored, rather 

 large. Calyx tubular-campanulate, somewhat two-lipped, teeth 

 broad or triangular-lanceolate, two upper deeply cleft, short; all 

 one to three-nerved, (the marginal veins scarcely to be regarded 

 as lateral nerves). Calyx also nerved from the sinuses, margins 

 ciliate. Yexillum obovate, emarginate, cuneate, margins mi- 

 nutelv waved; wings adherent to the keel, oblong, wrinkled, the 

 internal tooth-like process large, causing a conspicuous swell or 

 outward curve at the origin of the claws, tufttd, bearded on the 

 upper side below the stigma, and thence a scabrous bearded line 

 extending down nearly the whole length. Embryo legume 

 straight, oblanceolate, compressed, four to six-seeded, glabrous. 

 Mature fruit unknown."
