umbentes!

Herba (v. Suffrutex) erecta ramosa canescens, pube ramosa; foliis
lato-linearibus remote dentatis; racemis terminalibus.

1. BLENNODIA canescens.

LOC. In arenosis depressis.

DESC. Suffruticosa, sesquipedalis, caule ramisque teretibus. Folia vix
pollicaria paucidentata. Racemi multiflori, erecti, ebracteati. Flores
albicantes. Calyx incano-pubescens. Petalorum ungues calyce paulo
longiores. Stamina 6, tetradynama, filamentis linearibus membranaceis
apice sensim angustato.

OBS. This plant has entirely the habit, and in many important points the
structure of Matthiola, near which in a strictly natural method it must
be placed; differing, however, in having incumbent cotyledons, and in the
mucous covering of its seeds. The mucus proceeds from short tubes
covering the whole surface of the testa, each containing a spiral fibre,
which seems to be distinct from the membrane of the tube. A structure
essentially similar is known to occur generally in several families: to
what extent or in what genera of Cruciferae it may exist, I have not
ascertained; it is not found, however, in those species of Matthiola
which I have examined.
