stipitate, «-ovulate; style straight or curved, beardless; stigma 
minute or capitate, terminal. Legume sessile or stipitate, rather 
turgid, undivided, 2-valved; placenta more or less intruded and 
projecting within. Seeds funiculate reniform exarillate—Small or 
large shrubs, or herbs ; unarmed or with hardened spinescent petioles ; 
leaves imparipinnate; stipules free or adnate to petiole ; flowers’ 
in racemes or spikes ; inflorescences axillary or springing from wood 
of stem; bracts small, bractlets minute or 0? (Hwurope, cold and 
mountainous regions of Asia, and America’). 
91. Biserrula L.i—Flowers of Astragalus. Germen sessile o- 
ovulate ; style curved, rather thick, tapering at apex ; stigma capitate 
terminal. Legume linear, much flattened dorsally, longitudinally 
divided within by a very narrow septum connecting dorsal and 
ventral sutures into 2 lateral o-seeded cells; valves 2, lateral com- 
pressed ; keels simulating margins of legume, nearly equally toothed 
or serrated; teeth entire or minutely toothed. Seeds reniform 
exarillate; radicle long inflexed—A diffuse herb; leaves impari- 
pinnate; leaflets o, emarginate exstipellate; stipules 2, lateral, 
adnate to base of petiole ; flowers* few, in axillary long-pedunculate 
spikes ; bracts minute (Mediterranean’).
