14. LATHYBUS L. WILD PEA. , 



Much resembling Vicia, but usually larger with 

 broader leaves and flowers. Style-branches dilated and 

 flattish above, hairy along the inner side. 



1. L. violaceus Greene. Sparsely and minutely pubescent 

 throughout; stems slender, shrubby below, 1-2.5 m. high, acutely 

 angled ; stipules entire, narrow, less than half as long as adjacent 

 leaflet ; leaflets about 12, elliptic, obtuse, with a deflexed mucro ; 

 peduncles surpassing the leaves, many-flowered and rather dense ; 

 flowers 16 mm. long; lateral calyx-teeth much longer than the 

 tube ; the lowest equaling these and half as broad ; the upper pair 

 short, slightly connivent ; petals purple ; standard strongly obcor- 

 date; wings slightly shorter than keel. 



Common in the foothills, especially in the chaparral belt. 



2. Li. laetiflorus Greene. Sparsely and minutely appressed 

 pubescent; stems slender, herbaceous or somewhat shrubby 

 below, 1-2.5 m. high; leaves of rather firm texture, elliptic- 

 lanceolate; peduncles surpassing the leaves, loosely many- 

 flowered ; flowers about 22 mm. long ; lateral pair of calyx-teeth 

 broadly subulate, about equaling the tube, the lowest subulate, 

 longer than the tube, the upper pair very short, connivent at tip ; 

 petals nearly white, faintly flesh color; standard obcordate, the 

 sides abruptly reflexed, purple-veined ; wings meeting and con- 

 cealing the keel from above. 



Less common than the last, but having about the same range. 



3. Li. Alfeldi White. Glabrous or sparingly pubescent through- 

 out ; stem rather stout, flexuose, wingless ; stipules semicordate, 

 acuminate, thick, strongly reticulated, %-}4. as long as the leaf- 

 lets and often nearly as broad, the lower coarsely lobed, acu- 

 minately toothed ; leaflets 6-10, oblong to obovate, thick and stiff, 

 prominently reticulated, glabrous ; peduncles 6-10-flowered, much 

 exceeding the leaf ; flowers 2-3 cm. long, purple ; pedicels longer 

 than the calyx-tube ; calyx pubescent, upper teeth short, broadly 

 triangular, acute, lateral pair oblong-lanceolate, equaling the 

 tube, the lowest of equal length, subulate. 



Frequent in the foothills of our interior region.

A very handsome species of Riverside and San Diego County, said to have
