Apparently described from cultivated material grown from seed collected 
in the Antilles, the existence of a type of Ardisia crenulata Vent. remains to be 
determined. My recognition of the species is based on the full page illustration 
and ample original description by Ventenat, and the Poiteau specimen at Gen- 
eva from the Ventenat herbarium. In the absence of a holotype, I have desig- 
nated Ekman H12417 as icotype (US). This will provide a further reference to 
my interpretation of the taxon. 
I consider Parathesis crenulata a clearly defined species, not to be confused 
with P. serrulata (Sw.) Mez. It is restricted like the latter to the West Indies. 
The sharply acuminate often cuspidate leaves, minute closely appressed stellate 
often bizonal pubescence of undersurface of very young leaves, plant almost 
entirely glabrescent with age, larger flowers with slenderer buds, and anthers 
without hairs at apex are characteristics which clearly distinguish P. crenulata 
from P. serrulata. In P. crenulata the leaf blade is very thin and usually reticulate- 
veined on both surfaces and the margin, although repand and obscurely crenu- 
nl —_— subentire. The papillose-puberulent upper surface of petiole is to 
e noted.

Branchlets rather stout, persistently brown tomentose, the hairs minute; 
leaves with petioles 1-2 cm. long, canaliculate; leaf blades membranaceous, 
elliptic or obovate-elliptic, 8.5-15 em. long, 4.5-7.5 em. wide, apex abruptly 
acuminate, base decurrent on the petiole, stellate-pubescent on the undersurface 
at first, the fine hairs appressed, essentially glabrous with age, glabrous on upper 
surface, black-punctate, finely reticulate-veined, primary veins 12-15 on each 
side, conspicuous on undersurface, plane or slightly impressed on upper surface, 
margin conspicuously dentate almost to base; inflorescences leafy, terminal, 
narrowly paniculate, finely tomentose, 8-10 cm. long; flowers corymbose, 
finely tomentose, borne on pedicels up to 4 mm. long; buds about 5 mm. long; 
sepals 1.3-1.5 mm. long; petals about 5.5 mm. long, narrowly lanceolate, atten-
