This is described to be a shrub 6 or 8 feet high. The 
branches are flexuose, quite smooth with internodes scarcely 
an inch distant, and a single stout, sharp pointed, divaricate 
spine in each axil, 2 inches in length, the older ones being 
bare and sometimes again spiny; the younger ones bearing 
leaves and flowers. The leaves are smooth, fleshy, rounded 
at the apex, and tapering at base into the petiole, they are 9 
lines in length and 24 lines wide; the peduncles are 4 lin. 
long ; the calyx at first slightly pubescent, is urceolate, with 
5 projecting ribs which terminate in as many short teeth, with 
a mucronulate woolly apex. The corolla is broader and about 
the length of the last species, being 10 lines long, smooth, of 
a crimson colour, having a border of 5 short, rather erect 
lobes, with floccose margins, and a narrow intermediate pli- 
cature with tomentose edges and a small erect tooth in the 
centre. The crimson filaments are adnate by a central line 
to the base of the tube of the corolla for one third of its 
length, the upper part being wholly free, the lateral appen- 
dages being short, acute, and only 45th part of the length of 
the antheriferous portion, which is slender and subulate; the 
anthers are oblong, yellow, protruding beyond the mouth of 
the corolla. The fruit is unknown.* |

This genus was first proposed by Schott in 1829 (Wiener 
Zeitschrift 4.1180) upon a Brazilian plant considered to be 
identical with the Cestrum cauliflorum, Jacq. Hort. Schoen
