other and to the tube. Petals free from androceum, deciduous ; 

 standard obovate or oblong, subsessile ; wings oblong ; keel about 

 equal to or shorter than wings, obtuse. Stamens 10, 9 connate, 

 vexillary stamen free or connate at middle with remainder; filaments 

 not dilated ; anthers uniform. Germen sessile or stipitate, pauci- or 

 go -ovulate ; style filiform, curved above ; stigma terminal, capitate or 

 oblique. Legume unevenly globose or ovoid, surrounded by long- 

 persistent calyx, straight thick striated, indehiscent or rather late 

 becoming 2-valved. Seeds solitary or few, exarillate, often sparingly 

 albuminous. — Annual or biennial herbs ; leaves pinnate 3-foliolate ; 

 leaflets articulated, often denticulate ; stipules lateral, adnate to 

 petiole ; flowers 1 bracteate, in axillary or subaxillary racemes ; 

 bractlets {Northern temperate regions of Old World'). 



117. Trigonella L. 3 — Receptacle obconical to a variable height, 

 glandular within. Calyx gamosepalous tubular ; teeth or lobes 

 nearly equal. Petals free from androceum ; standard sessile or 

 shortly and broadly unguiculate ; wings unevenly oblong, shorter 

 than standard ; keel shorter than wings or very short, obtuse. Sta- 

 mens 10, 2-adelphous (9-1), or vexillary stamen connate at middle 

 with remainder ; filaments free at apex, more or less dilated below 

 uniform anthers. Germen sessile or shortly stipitate ; ovules oo, 2- 

 seriate ; style rather thick or filiform ; stigma dilated, terminal 

 or subterminal. Legume either thick, long-beaked or else linear, 

 compressed or terete or flat and broad ; straight, arched, or falcate, 

 indehiscent or 1— 2-valved, continuous within. Seeds exarillate. —
