the Quinta do Val. Aug.-Dee. — St. numerous weak slender 
much branched from the base forming a low spreading tuft, 
presently in fr. elongated to the length of 1 or 2 ft. or more, 
the ends ascending. L. crowded small i-1 in. long quite entire 
dull greyish-gr. clothed like the branches with copious close- 
pressed whitish silky forked hairs. FI. very numerous pure 
brilliant white in terminal corymbose racemes which are much 
elongated in fr. Pouch oval or elliptic erecto-patent. Seeds 
1 or 2 in each cell. — Seems scarcely worth distinguishing as a 
var. from the usual European garden pi. The st. and branches 
are indeed woody or suffrutescent downwards, but the pi. is 
notwithstanding truly annual or only accidentally of longer 
duration in Madeira.
