20. TROPIDOCARPUM Hook. 



Erect or diffusely spreading annuals with pubescent herbage, pinnatifid leaves 

 and leafy racemes of rather small yellow flowers. Sepals concave, ovate-oblong, 

 spreading. Petals cuneate-obovate. Stamens tetradynamous; anthers roundish. 

 Style slender, sometimes short. Pod completely or partially 2-celled, or 1-celled, 

 strongly flattened contrary to the narrow partition, or only the upper part flat- 

 tened, or somewhat inflated; valves 2 to 4, opening from above; seeds in 2 or 4 

 rows. — Species 2, California. (Greek tropis, keel, and karpos, fruit, in reference 

 to the carinate valves of the capsule). 



Variation in the pod. — The valves in Tropidocarpum gracile may dehisce from above, or 

 sometimes from below, or subequally throughout (Tracy, Benj. Cobb). In plants of this same
