A diminutive species observed at different periods in the 
clefts of rocks on the Coast of Barbary by Messrs. Shaw, 
Vahl, and Desfontaines; perhaps the smallest in the genus, 
where it is remarkable for the pale violet-colour of the 
corolla, which turns, when dry, to a full bright blue. 
It is not recorded in the Hortus Kewensis; and has been 
probably now first introduced by Mr. Kent, in whose col- 
lection at Clapton it flowered last summer in the green- 
house. 
Stem sometimes lying along the ground, 3-4 inches 
Jong, round, smooth, in some cases very much branched, 
dotted with shortly broken thickset tile-red lines. Flowers 
numerous, small, paniculately racemose, racemes termi- 
?
