Obs. Floribus ignotis dubioe generis planta cujus exem- plaria tria in Herb. D. Sabine exstant. Cotyledones ccrtc incumbentes et linearcs, basibus tamen cms radiculare embryonis vix occupantibus.

EUTREMA.

Siliqifa (abbreviata) anceps, valvis carinatis, dissepimento incompleto ! Cotyledones incumbentes.

Herba hahific omnino Brayse et Platypetali, quibifs wa,vime affine genus, distinguendum tamen facile siliqua ancipiti, dis- sepimento incompleto, et seminum funiculis.
