Lathyrus litoralis (Nutt.) Endl. 

 A maritime species occuring on sea shore of Marin Co. and nortli- 

 ward in California (Jepson: Flora of Western Middle California, 1901. 

 p. 298). 



L. maritimus Bigelow. 



Perennial herb, with creeping rootstock, stout, 30 cm. high or more, 

 glabrous, stems sharply angular, spreading; leaves with many pairs of 

 leaflets, these ovate or elliptical; leafstalk ending in a long tendril; 

 flowers large, purple; pod hairy when young, 3 — 5 cm. long. 



Sandy and gravelly coasts of Northern Europe, not going further 

 south than Picardy; Arctic Europe, Asia, and America, where it ex- 

 tends down the eastern coast. A form called L. californicus Dougl. is 

 found on sea shores of Washington, and a variety aleuticus White, is 

 found in the arctic parts of America. 



Lotus corniculatus L. var. crassifolius Pars. 



Perennial stock, with a long taproot; stems decumbent or prostrate, 

 1 — 5 dm. long; leaves pinnate, somewhat fleshy; leaflets ovate, pointed, 

 flowers yellow. 



This variety represents a race characteristic to the sea shores of 

 Europe, but is not related to L. crassifolius Greene, which is a different 

 plant of Western America, where it does not follow the coast. 



Distributed over Europe, Northern and Central Asia, the mountain- 

 ous districts of East Indian Peninsula, and Australia. 



Lupinus arboreus Sims. 



Arborescent or suffrutescent, silky pubescent on young stems and

 3 — 6 em. long, 9 — 11 on first leaves, 6 — 8 on later leaves from the 

 axils, these smaller; corolla sulphur-yellow, keel purple tipped; cotjdedon 

 of the seedling petioled.
