3802 NATURAL HISTORY OF PLANTS. 
141. Nissolia Jacg.'—Flowers nearly of Chetocalyx, smaller ; 
calyx truncate; teeth 3, setaceous, nearly equal. Stamens 10, 
2-adelphous (9-1) close to base; vexillary stamen connate at 
middle with remainder into a tube. Germen subsessile ; ovules few ; 
style slender, curved or sinuate ; apex minutely capitate or obtuse, 
stigmatiferous. Legume linear, indehiscent ; segments flat or convex, 
square or oblong, striated ; last segment dilated into a much com- 
pressed, obliquely obovate, samaroid wing ;’ seeds few reniform 
exarillate—Herbs or undershrubs, twining; leaves imparipinnate ; 
leaflets few, exstipellate, setaceous; flowers’ racemose; racemes 
short, either axillary or branched crowded at extremities of 
branches; bracts narrow; bractlets 0 (Zropical and subtropical 
America’). 
142? Ctenodon H. By.’—Receptacle minute concave, lined by 
a thin disk. Calyx gamosepalous subcampanulate ; lobes 5, longer 
than tube; 2 superior broader than others; lowest longer than 
lateral ones, with a long point. Petals unguiculate; standard 
obovate, finally reflexed ; wings very oblique, l-auriculate at base ; 
keel falcate beaked. Stamens 10, 1l-adelphous; filaments connate 
into a tube rather oblique at apex and longitudinally cleft below; 
anthers uniform. Germen shortly stipitate; ovules ; style fili- 
form, slightly curved; apex scarcely dilated, stigmatiferous. Legume 
stipitate ; segments oo; superior suture nearly straight or arched ; 
inferior deeply sinuate. Seeds...Pp—A small undershrub, branched 
from base; leaves subimparipinnate ; leaflets sessile oblong, very 
uneven at base, acuminate at apex; midrib produced into a rather 
sharp bristle; rachis thickened into a subglobose rather pubescent 
gland at insertion of each leaflet; stipules long subulate; flowers 
in loose long-pedunculate axillary racemes; pedicels slender; bracts

2 In Chetocalyx Schotti and C. Wislizeni 
Torz., figured in Unit, St. Mex, Bound., Bot., 
t. 18, the last segment is more or less dilated ; 
whence either these species ought to be referred 
to Missolia, or the two genera should be united 
into one, the sections of which are scarcely well- 
defined. The species of both ought therefore to be 
carefully examined.
