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. 8. the leaves are 
4-6 lines long, Z 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,
