PEA FAMILY 331 



The glands. — The glandular prickles of the rachis are slender, or in varying degrees pustu- 

 late-dilated downward. When pustulate-dilated they are "sessile." Late in the season the whole 

 prickle or the slender tip of the dilated ones are often more or less deciduous. Towards the 

 southern limits of the range the calyces generally bear many glands, towards the north, espe- 

 cially at the north limits, the calyces are destitute or mainly destitute of glands. 



The geographic distribution requires notice. It is unusual for a species occurring on both 

 sides of the San Bernardino Mts. to extend north along the coast to the Napa Range and then 

 recur in the northern Sierra Nevada.

19. PAROSELA Cav. Dalea 



Ours small shrubs or small trees. Herbage glandular-punctate. Leaves un- 

 equally pinnate or simple ; stipules small, subulate ; leaflets small, entire. Flowers 

 in terminal spikes or racemes. Calyx with 5 nearly equal teeth or lobes, persistent. 

 Banner cordate or auriculate, inserted opposite the cleft stamen-tube. Stamens 

 monadelphous. Pod ovate, compressed, usually indehiscent, more or less included 

 in the calyx, 1 to 2-seeded. Seeds reniform. — Species about 100, temperate North 

 America and along the Andes to Chile. (Anagram of Psoralea.)
