One of our smallest and most delicate plants, (only two or three inches 
high, branched. E.) Leaves dark green ; leafits elliptical, tapering each 
way, on leaf-stalks, very entire, thickish, from six to twelve pairs, with 
an odd one. Flowers in a close corymb, which, as the fruit ripens, 
lengthens out into a bunch. Petals spatula-shaped, white, as long 
as, and narrower than the calyx; generally entire, but sometimes 
slightly notched. Pouches broad egg-shaped, blunt, convex underneath, 
flat above; valves keeled. Jacq. (Mr. Brown has suggested that the 
entire apex of the pouch, (not so when mature, Sm.) and each cell con¬ 
taining two seeds, (or rather, “more than one,” the number not being 
limited precisely to two,) in this species, with accumbent cotyledons, are 
sufficient to constitute a new genus, designated Hutchinsia , after a lady 
whose memory will long be cherished by Botanists, and whose name has 
also been conferred still more appropriately, by Agardh, on a genus of 
marine plants ; Conferva ; Polysiphonia of some authors. E.)
