& Most nearly related to C. latifolia obovata Miquel, which is described as with pedun- 
cles 5 cm. long, leaves with only four or five pairs of lateral veins, and glabrous 
perigonium. Local name ‘“cibuero” or ‘“‘gummilera.”’ 
Coccoloba cyclophylla Blake, sp. nov. 
Tree, 8 meters high, with a trunk 20 em. in diameter; branches grayish, glabrous, 
sulcate in drying; upper internodes 1 to 3 cm. long; sheaths close, equaling the inter- 
nodes, sparsely puberulous below, papillose above, mainly deciduous; petioles stout,

blades (5.5) 9.5 to 12 em. long, 6 to 11.3 cm, wide, suborbicular, retuse at the broadly 
rounded apex, broadly rounded and slightly cordate at base, entire but somewhat 
wavy-margined, pergamentaceous, above dull green, glabrous, finely prominulous- 
reticulate, beneath brownish green, prominent-reticulate, glabrous except for the 
hirtellous costa, axils, and chief veins, the main veins 10 to 12 pairs, prominent; 
straightish and subparallel, united at their arcuate tips; spikes solitary, straightish, 
axillary and terminal, rather loosely flowered, 7 to 14 em. long, 4 to 6 mm. thick; 
peduncles hirtellous, 1 em. long or less; rachis hirtellous; nodes about 4-flowered ; 
bracts suborbicular, rounded, hirtellous, 1 mm. long; ochreolae scarious, hirtellous 
below, 1.5 to 2.5 mm. long; pedicels 1.5 to 2 mm. long, hirtellous, jointed near apex; 
perigonium subglobose, hirtellous, 1.6 mm. Jong; filaments lance-subulate, 0.6 mm. 
long; ovary ellipsoid-trigonous; styles 3, two-thirds as long as ovary; segments of 
fruiting perigonium united for about one-third their length, suborbicular, 
Type in the U.S. National Herbarium, no. 537,207, collected at San Martin de 
Loba and vicinity, Lands of Loba, Department of Bolivar, Colombia, April or May, 
1916, by. H, M. Curran (no. 47), 
Nearest to Coccoloba rotundifolia Meisn. of Santo Domingo, which has smaller, more 
deeply cordate leaves mostly broader than long, with only 6 or 7 pairs of nerves, less 
prominently reticulate beneath, and with the costa puberulous on the upper surface 
of the leaf, 
Ruprechtia oxyphylla Blake, sp. nov. 
Shrub or more probably small tree, much branched; branches grayish, glabrous ; 
sheaths slightly loose, truncate, subcoriaceous, sparsely hispid-strigose, persistent, 
1.5 to 2.5 mm, long; petioles rounded beneath, flattish above, sparsely strigose and 
sometimes hirtellous on margin, 2.5 to 5 mm. long; leaf blades 4.5 to 9 em, long, 1.5 
to 4.2 cm. wide, ovate-lanceolate to elliptic-lanceolate or elliptic-ovate, acute or 
acuminate and usually slightly falcate, the extreme tip obtuse, rounded or cuneate 
at base, somewhat inequilateral, repand or subentire, chartaceous, above green, in age 
pale, somewhat papillose but subglabrous, beneath scarcely paler green or in age 
rufescent, usually sparsely hispid-pilose along the costa and chief nerves or sub- 
glabrous, but sometimes subdensely hispid-pilose over the whole under surface; 
chief veins 10 to 13 pairs, like the veinlets obscure above or in age prominulous, 
beneath prominulous, slightly curved, in age like the secondaries prominulous- 
reticulate, the tertiaries obscure or slightly prominulous in age; staminate spikes in 
clusters of 2 to 4 on the growth of the previous season, | to 1.5 cm. long, 5 to 7 mm. 
thick, densely flowered, the axis densely hirtellous with dull whitish hairs; flowers 
in clusters of 2 to 4; pedicels 2.5 to 3 mm. long, articulate well above the middle. 
sparsely hirtellous; perianth 2.8 mm. long, 6-parted nearly to base, the very short 
tube sparsely hirtous, the segments elliptic, subtruncate, short-ciliate, glabrous or 
sparsely hirtellous dorsally; stamens 8, the slenderly subulate filaments glabrous, 3.5 
to 4 mm, long, the anthers 1 mm. long, the ovary rudiment hispid; pistillate spikes 
from the previous season’s growth, solitary in the axils, the axis 2.8 cm. long or less,
