1. P. vulgdris (L.) ; I. scattered, lower I. smaller oblong, upper 

 1. linear-lanceolate, cal. -wings elliptic mucronate their veins 

 branched the lateral joining a branch of the central vein, caps, ob- 

 cordate, lateral bracts shorter than the pedicels. — E. B. 76. — 

 St. prostrate, ascending. L. scattered. Racemes terminal. Fl. 

 blue, pink, or white. Central vein of wings nearly simple end- 

 ing in a mucro ; lateral only branched externally ; branches 

 joining ui loops and also with the upper ones of the central 

 vein. Lobes of aril unequal, blunt, lateral ones ^ as long as the 

 seed which is a little stalked within the aril. Upper part of st. 

 and ped. sometimes pubescent (P. ciliata Lebel). P. oxyptera 

 (R.) is a state with smaller fl., and fr. broader than the wings. 

 E. B. S. 2876.-/3. P. depressa (Wend.) ; lower 1. mostly op-

 lateral. 8y. E. B. 187. P. serpillacea Weihe. — y. grandiflora ; 

 upper 1. large lanceolate, cal. -wings oval apiculate, their lateral 

 veins rejoin the mostly simple central vein near its tip and have 

 many netlike veins externally. Fl. deep blue. — Dry pastures

2. P. calcdrea (F, Sch.) ; I. chiefly in an irregular terminal 

 rosette large obovate blunt those of il.-st. short smaller lanceo- 

 late, cal.-wings oblong their veins branched the lateral looping 

 with a branch from near the middle of the central vein, caps, 

 oblong-obcordate, lateral bracts shorter than the pedicels. — P.

 rosette, upper 1. oblong-lanceolate, cal.-wings oblong or obovate 

 blunt their veins simple or slightly branched free, caps, obcordate 

 broader than the wings, lateral bracts shorter than the pedicels. 

 — Rosette at crown of rootstock, its 1. much the largest 

 broad rounded at the end. Fl.-st. from the axils of the rosette, 

 simple, short ; upper 1. acute ; racemes terminal. Cal.-wings 

 longer than caps. Lobes of aril nearly equal, blunt, ^ as long 

 as seed. — a ; caps, rounded at the base, fl. very small. 8y. E.
