Casearia Jacquin
Casearia decandra
Casearia decandra Jacquh. 1760:21; 1763:133, pl. 85.-Little & Wadswoxth,
1964:366, pl. 170.
Casearia parvifora Jacquin. 1780:66, pl. 127, nm. superfl.
Casearia parvifolia Willdenow, 1799,2:629, nom. superfl.
Shrub or tree to 8 m; flowers greenish white to white,
fragrant; calyx 4-6 mm long, sepals reflexed in anthesis; style
simple; mature fruits 8-12 mm broad, white, arils deep yellow.
Hispaniola through Antilles to northern South America; in
Dominica in west coast woodlands from near sea level to -200
m: Cabrits (Hodge 469, Webster 13315), Petit Coulibri
(Whitefoord 6036), sine loc. (Duss s.n.).
It is remarkable that no collections have been made of
Casearia sylvestris Swartz, a species to be expected on
Dominica. It has a calyx 2-3 mm long, sepals erect at anthesis,
a trifid style, and a mature fruit only 3-4 mm broad.
The nomenclature of these two species is excessively
intertwined, involving easily (and frequently) confused epithets
parviflora and parvifolia (discussed by Kiger, 1984:458) under
Samyda parvijlora.
