Annual. Stems numerous, all decumbent, erect at the apex, 

 usually simple. Leaves sessile, in whorls of 3 to 5 ; the upper ones 

 usually alternate ; all linear-strapshaped, entire. Plowers few, in a 

 dense raceme, which lengthens after flowering. Pedicels shorter 

 than the calyx. Calyx-segments strapshaped, sub-obtuse, clothed 

 with gland-tipped hairs. Corolla six times as long as the calyx ; 

 spur nearly as long as the corolla, acute, very slightly curved, in a 

 line with the under side of the corolla. Capsule sub-globular, half 

 as long again as the calyx, each of the two valves splitting into 

 3 segments. Seeds shining, reniform, surrounded by a broad 

 concavo-convex striated wing. Plant glaucous, glabrous except 

 the upper part of the stem, rachis, peduncles, and calyx-segments, 

 which are clothed with gland-tipped hairs.

 and St. Blazey's Bay, Cornwall ; introduced with ballast, but com-
