BLAKE—AMERICAN SPECIES OF HOMALIUM. 229 
crenate-serrate with 10 to 22 pairs of blunt teeth, bearing 6 to 10 pairs of lateral veins 
with prominulous-reticulate secondary and tertiary veinlets, glabrous on both sides; 
petioles glabrous, 6 to 11 mm. long; peduncles axillary and terminal, glabrous, 2.6 to 
4.2 cm. long; panicles conic or pyramidal, loosely flowered, 6.5 to 9 cm. long, the 
lowest branches 1.8 to 6.3 cm. long, the upper much shorter, puberulous with dull 
incurved or ascending hairs; pedicels 1 to 4 mm. long; fruiting calyx tube turbinate, 
contracted into a distinct but short pediform base, slightly sulcate, rather densely 
puberulous with dull incurved hairs; calyx segments 5 to 7, lanceolate to ovate- 
lanceolate, narrowed to an acutish tip, puberulous outside, more densely so inside, 
3 to 3.5 mm. long, 1.2 to 1.6 mm. wide; corolla 8 to 12 mm. wide; petals 5 to 7, ovate, 
obtusish, griseous-puberulous on both sides, 3.5 to 5 mm. long, 2 to 2.8 mm. wide; 
stamens in fascicles of 3 or 4, the filaments glabrous or pilose at the base, shorter than 
the petals; styles 3, distinct, pilose at base; ovary conic, densely dull-pilose.

SPECIMENS EXAMINED: 
AnTiaua: Duss 42 (Y). 
TUADELOUPE: Duss 2427 (Y). Abundant at altitudes up to 600 meters, flowering 
in May and June, Duss 2998 (N), 
MARTINIQUE: Sieber 143 (N). Fort Vaillant, December, 1867, Hahn (G). In 
1879, Duss 1806 (N). 
A single flower of Hahn’s piant from Martinique has a cluster of 7 filaments before 
one of the petals, but other fascicles in the same flower and on other flowers of the 
same specimen have the normal number of 3 or 4. 
H. L. Gerth van Wijk, in his Dictionary of Plant Names, gives the following local 
names for this species: ‘‘acoma,’’ ‘‘acomas 4 grappes,”’ ‘‘acouma”’ (Martinique), ‘bois 
d’acouma,”’ ‘‘bois incorruptible,” ‘‘mavévé,”’ and ‘‘traubiger akomasbaum.”’ 
9a. Homalium racemosum barbellatum Blake, subsp. nov. 
?Homalium obtusatum Turcz. Bull. Soc. Nat. Moscou 31!: 465. 1858. 
Similar to the species; leaf blades barbellate in the axils of the veins beneath, 
sometimes smaller, thicker, and obtuse, 4.5 to 12.5 cm. long, 2.5 to 6 cm. wide; racemes 
simple or essentially so, the peduncles 4.2 cm. long or less, the rachis 1.5 to 8 cm, long; 
fruiting calyx often with conspicuous pediform base as long as the body; sepals usually 
lanceolate and acuminate, rarely ovate, 2.8 to 3.5 mm. long, 0.7 to 1.4 mm. wide; 
stamens, styles, and ovary as in.the typical form.
