268 PHANEROGAMOUS PLANTS. 



about half as large as in Lathyrus palustris. Segments of the calyx 

 linear-lanceolate, acute, the 3 inferior rather longer than the tube, 

 the 2 superior shorter. Corolla purple? This is certainly a congener 

 of Orobus littoralis, notwithstanding the one-flowered peduncles, a 

 character which occurs in no other species except 0. saxatilis and a 

 variety of 0. viciceformis. [The name under which this plant was 

 first described is substituted, and there is, moreover, a published L. 

 villosus. The following species, of very different habit, is left under 

 Orobus, although later authorities merge the genus in Lathyrus.'] 



3. OROBUS, Toum. 



1. Orobus littoralis, Qray. 



Orobus littoralis, Gray, in Pacif. R. R. Expl. 12, part 2, p. 54, t. 6 ; Torr. Bot. 



Mex. Bound, p. 77. 

 Astrophia littoralis, Nutt. in Torr. & Gray, Fl. 1, p. 278. 



Hab. On the sea-coast, near Gray's Harbor, Washington Territory. — 

 Plant apparently two feet or more in - height, rather stout, much 

 branched. Leaflets, mostly 4, varying from linear-spatulate to 

 obovate-oblong. Stipules ovate, semisagittate. Racemes 5-8-flowered, 

 much longer than the leaves ; the flowers about as large as those of 

 Lathyrus maritimus. Banner bright purple, obovate-cordate, one-third 

 longer than the paler wings and keel. Stamens diadelphous, 9 and 1 : 

 anthers oblong. Style slender, narrowly linear, pubescent and slightly 

 grooved on the inner side. Endlicher places Astrophia in Lathyrus, 

 but we think it much nearer Orobus. 



4. GLYCYRRHIZA, Toum. 



1. Glyctrrhiza lepidota, Nutt. 



Hab. On the Kooskooskee and Columbia Rivers; also in fertile 

 places along the Sacramento; sometimes forming large patches. — The 

 stem is 2 to 3 feet high. This species extends eastward to the Mis- 

 sissippi. We find no constant differences between the original Q. 

 lepidota and the later O. glutinosa of Nuttall.
