are united in K. pa eg are analogous to the tube of nine connected filaments. The lateral sessile petals correspond 
with the carina, and the others, whose claws are connected, with the ale and carina; the five sepals alternate 
with them, as the stamens ia with the petals. The fruit resembles somewhat the indehiacent spiny legume of 
an Onobrychis ; and, in all the specimens we have examined, it is one-seeded when ripe.

almost naked rocks; in flower principally in July and August, but also at other seasons, always after heavy rains. — 
Root white, fleshy, tuberous, often bifurcated. Stems 8-16 inches long, ascending, much branched. Leaves 14-2 or 
even 3 inches long, 2~4 lines wide. Peduncle 4-5 lines long. Sepals of the same length ; petals 5 lines long and
