Both varieties of this species, which I found in the 

 places quoted, in 1826, bear much the appearance of a LinuM 

 in habit. It is distinct from all others belonging to the same 

 genus, in the greater length of its peduncle, in its corolla 

 having a much thicker and more infundibuliform tube, with 

 its stamens included altogether within its mouth, and a 

 narrow border cleft to its base, into oblong reflected seg- 

 ments, in which respects it more nearly resembles Fabiana. 

 In the var. a, the leaves are 4 to 9 lines long, 1 line broad, 

 the internodes 6 to 10 lines distant : in var. fi. the leaves are 

 4-6 lines long, \ to 1 line broad, the internodes 3 lines apart : 

 the peduncle is 7 lines long ; the calyx 3 lines, cleft deeply into 

 5 linear erect segments ; the tube of the corolla is 6 lines long?
