This is said to resemble much the preceding species; and it comes from near the same 
locality. It differs only in the form and pubescence of its leaves; the axils are ¿—1 in. 
apart; the leaves are oblong-elliptic, subacute at both ends, pubescent at first, afterwards 
glabrous above, with close patent nerves, 13-22 in. long, 6-7 lines broad, on petioles 
5 lines long; peduncle 2 in. long, twice trichotomously divided. 
4. Skyrantaus Havanensis, nob.: Neriandra Havanensis, Müll. Linn. xxx. 401. In Havana (Sagra 
274) : non vidi. 
A species with very slender branches, trichotomously divided, with axils 4 in. apart; 
leaves broadly ovate, inequilateral, and suddenly acute at the base, terminated by a 
short, oblique, acute, often recurved acumen, glabrous, with many close, parallel, 
straight nerves conjoined near the margin and ¿-1 line apart; they are 2-22 in. long, 
14-12 in. broad, on petioles 6 lines long; panicles trichotomously branched, shorter than 
the leaves, bearing 12 to 18 flowers, on slender pedicels 2 to 4 times as long as the 
calyx; sepals broadly ovate, rounded and mucronulate at the apex, 11 line long; tube of 
corolla 34 lines long, campanulate in the mouth; segments 53 lines long, triangularly 
_inequilateral; anthers small, ovoid, terminated by filiform appendages of nearly equal 
length, twisted together; ovaries short, glabrous. 
The Veriandra suberecta, A. DC., founded on the Echites suberecta, Sw. et And. (non 
Echites suberecta, Jacq.), belongs to my genus Chariomma. It is referred by Bentham 
and Hooker (Gen. ii. 705), to Urechites, here confounding the two plants figured by 
Andrews and Jacquin under the same name, which are very distinct. 
In p. 28 I have alluded to a mistake imputed by Messrs. Bentham and Hooker to 
Müller, in regard to the supposed identity of Cameraria and Skytanthus; but I find this 
not to be Miiller’s mistake, but one of the many blunders of Prof. Grisebach, who in 
his Cat. Pl. Cub. n. 16, p. 170, confounds together Cameraria latifolia and Neriandra 
Havanensis. 
CHARIOMMA *. i 
Most of the plants forming this group were placed, doubtfully, by De Candolle, in 
Neriandra, a genus since abandoned ; and they certainly differ widely in several respects. 
Neriandra (now Skytanthus, by right of priority) has a rather small hypocrateriform 
corolla, with narrow segments; the stamens are seated below the mouth, and the 
twisted appendages are exserted; there is no disk. On the other hand, in Chariomma 
the corolla is larger (often very large), with broad dolabriform segments, the stamens are 
wholly included, being inserted below the middle of the tube, and there is a conspicuous 
disk. The type is the Echites suberecta of Swartz and Andrews (not of Jacquin).
