BOTANY. 7 
Suffruticose, pretty regularly branching, softly pubescent throughout, 14-2 feet high ; 
branchlets leafy and umbellose, subflexuous, with internodes scarcely as long as the leaves. 
Leaves imparipinnate; leaflets 3-5, rhombic-ovate, acute, mucronulate, mostly alternate. 
Stipules minute, fusiform, tomentose ; umbel stipitate, shorter than the leaf, 2-4-6-flowered, 
with an oval bract in it. Flowers small, subsessile, yellow with purplish tips. Calyx 
tubulate-campanulate. LLegumen 1-2-seeded, pubescent, pendulous, incurved, with a subulate 
uncinate and somewhat refracted rostrum. Differs from H. decumbens by being more branched 
and pubescent, by mucronate leaves, stipules not spinose, peduncles of the umbels considerably 
shorter, smaller flowers with purpurescent tips and by legumes not carinate and mostly one- 
seeded. Tejon Pass; September.
