1. Cremolobus aphanopterus, Sp. Nov. (Tab. 3.) 



O. annuus, parvulus, subglaber ; foliis pinnatipartitis ; racemis elon- 

 gatis; siliculce valvis fere apteris minimis stipitem gracilem liaud 

 excedentibus ; stylo elongato e basi crassa subulato. 



Hab. Andes of Peru, near Obrajillo. 



Root slender, annual. Stem slender, simple or branching above, 

 about a span high, glabrous, or beset with a few minute simple hairs. 

 Leaves small (6 or 8 lines long), glabrous or nearly so, mostly sessile, 

 deeply pinnatifid ; the divisions oblong and very obtuse. Racemes 

 elongated, strict, many-flowered. Pedicels 2 or 3 lines long. Flowers 

 very small : petals apparently white, obovate, unguiculate. Stamens 

 6 : filaments filiform. Stipe as long as the ovary with its style ; the 

 former consisting of a pair of rounded, scrotiform lobes or cells, sepa- 

 rated by the very thick axis, or dissepiment, which is continued into 

 the large and long style, the tapering apex of which is crowned by a 

 globular, undivided stigma. Silicle very small, minutely puberulent 

 under a lens ; the rounded lobes or valves scarcely if at all above half 

 a line in diameter, not longer than the stipe, not rugose nor reticulated, 

 nearly wingless, but surrounded by a slight and wavy or interrupted 

 margin. Seed nearly orbicular, resupinate-pendulous, so as to make 

 the ascending radicle internal !
