the stipules, the pedicels about 5 mm long, the bracts subtending 
the pedicels ovate, acuminate, striate, 1.5 mm long. Flowers 
about 1 cm long, purplish. Calyx sparingly pubescent, membran- 
aceous, 3 mm long, the upper two teeth usually wholly united 
into a 2-nerved, triangular-ovate, acute to obtuse, 1.2 mm long 
lobe, sometimes 2-dentate at the tip, the lower three teeth sub- 
equal, 1-nerved, ovate-lanceolate, acuminate, about 1 mm long. 
Petals glabrous, the standard broadly obovate, rounded or some- 
what retuse, sessile or with a very short claw, base cuneate, 
about 9 mm long and 8 mm wide. Wings oblong, slightly in- 
equilateral, free or nearly so, rounded, about 10 mm long and 
3.5 mm wide, the claw 1.2 mm long, basal lobe rounded. Keel 
petals about 8 mm long and 3 mm wide, slightly falcate, . 
oblong-obovate, rounded, the claw as long as that of the wings. 
Vexillary filament free from the base, the other nine united into 
a tube, the free parts of the filaments 1 to 1.5 mm long, all 
fertile, the anthers uniform. Ovary on a 1 mm long stipe, linear, 
slightly pubescent, about 4 mm long; ovules about 6; style 
curved, glabrous, about 3 mm long, the stigma minute. Fruit 
unknown.

I have placed this proposed new genus in the Papilionatae-Hedysareae, 
’ and with doubt in the Desmodiinae, as the fruits are unknown. It is 
strongly characterized by its long, straight, trifid, rigid spines and its 
1-foliolate, shortly petioled leaves, the leaflet being minutely stipellate and 
elliptic or oblong-elliptic in shape. It does not appear to be closely allied to 
any previously described genus either in the group in which it is placed, or in 
other groups of the Papilionatae, although in some respects it is suggestive 
of the New Caledonian genus Arthroclianthus Baill. It is, however, radi- 
cally different from Baillon’s genus in general appearance, vegetative : 
characters, floral characters, and in its trifid spines.
