“ An interesting but humble plant,” Messrs Torrey and Gray 
observe, “ which seems to stand between Platystemon and Hypo- 
coum, two genera having apparently little relationship, yet that 
ought, notwithstanding their anomalies, not to be removed from 
Papaveracee, It agrees with the latter in its definite stamens, 
and with the former in the foliage and floral envelopes, dilated 
filaments, &c. The torus is somewhat like that of Chryseis on 
4 small scale.” 
The following is Mr Nuttall’s character of this genus :— 
Sepals 3, somewhat pilose. Pet.5—6. Stamens 4—6. Fila- 
ments membranaceous, dilated* upwards; anthers very short, 
the cells disjoined. Stigmas 3, (rarely 4) linear, very short, 
sessile, Capsule pod-shaped, slender, 3 (rarely 4) valved : valves 
flat, l-nerved, dehiscing from the apex to the base, not separat- 
ing from the placente, Seeds numerous, smooth, and shining, 
subglobose.— A very small, annual, glabrous, and somewhat 
glaucous herb. Stamens slender, dichotomously branched. 
Radical leaves in a rosulate cluster, spathulate; cauline ones 
~ linear or linear-spathulate, opposite; the lowermost ternate, 
entire. Peduncles axillary, filiform, 1-flowered. Flower very 
small, ochroleucous,
