34 LUPINUS. 



To the cup clovers, with concave involucres and usually inflated, corollas in fruit, 

 Prof. Greene has added these species. 



T. Grayi, Loja, which is T. barbigerum, var. Andre wsii, Gr. Seemingly a good 

 species. 



[T. flavulum, Greene; T. virescens, Greene, and T. Grambelii, Nutt., are forms 

 of T. fucatum, Lindl., which varies from wet meadow-land forms, a foot or more 

 high, with heads of 20 flowers, 2 inches broad, to the upland form T. Gambelii, Nutt., 

 scarcely half as high, bearing heads with only 3 or 4 flowers.] 



T. hydrophyllum, Greene. Flaccid branches 1-2 feet long: stipules ovate, entire: 

 leaflets linear to oblong, those of the lower leaves narrowest: peduncles short: involucre 

 of about 5 bracts: calyx-teeth very long. Apparently a good species hitherto called 

 T. amplectens or a variety of T. depauperatum, to which the following may ba 

 referred. ;.'-> ' . .u***,-" -* - -., qj 



T. laciniatum, Greene. Upper leaves broad truncate, 3 dentate at apex, lacin- 

 iately toothed or pinnatifid. 



HOSACKIA. 



In Bay- Reg. Bot. Lotus Americanus is H. Purshiana of this book; L. Wran- 

 gelianus is H. subpinnata; L. humistratus, Greene, is H. brachycarpa; ~L. 

 denticulatus, Greene, is H. subpinnata, var. major, which seems to be a good 

 species; L. micranthus is H. parviflora; L. rubellus and L. nudiflorus are H. 

 Strigosa the former a coast form, the latter of the interior. L. hirtellus, Greene, 

 is also probably only a form of the same species. It. formissimus, Greene, is H. 

 gracilis; L. pinnatus is H. bicolor. L. eriophorus, Greene, is H. tomentosa. 

 Ij. leucophseus, Greene, is distinguished from Bentham's H. grandiflora by velvety 

 instead of nearly glabrous leaves and smaller flowers; perhaps better considered as 

 Hosackia grandiflora, Benth., var. anthylloides. Gray. L. Benthami, Greene, 

 is H. cytisoides. 



!L. Bioletti, Greene. Slender, wiry branches, 2 feet long, prostrate, canescent, with 

 short oppressed hairs: leaflets usually 4, cuneate-obovate: umbels pedunculate, brac- 

 teate, 6-10 flowered: calyx-teeth triangular, erect: corolla 2 lines long. 

 , We would label this H. Bioletii (Greene). 



LATHYRUS. 



Ii. Jepsonii, Greene. Nearly or quite glabrous: stem 5-8 feet long, strongly winged: 

 leaflets 8-12, linear lanceolate, acute, 2-3 inches long: stipules small, setaceously 

 acuminate: peduncles about equaling leaves: flowers rose-purple: calyx teeth ovate 

 lanceolate, nearly equal in length: pod 12-16 seeded.
