240 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
7.5 mm. long, short-stipitate; pedicels about 2 mm. long; fruiting perianth 3.8 to 4.1 
cm. long, the trigonous-urceolate tube 1.2 cm. long, densely pilose and pilosulous 
with sordid hairs, the long ones loosely ascending or spreading and with enlarged 
subglandular base, the short ones appressed; outer perianth segments spatulate, 
obtuse, broadest above the middle, appressed-pilose and spreading-ciliate, scarious, 
triplinerved and and reticulate, 2.6 to 2.9 cm. long, 6 to 7.5 mm. wide; inner segments 
lance-spatulate, obtusish, reticulate-veined, attached to the tube only at its base, 
clawed, 7 mm. long, 1.4 mm. wide; achene ovoid-trigonous, mucronate, glabrous, 
shining, olivaceous, 9 mm. long, 4.5 mm. wide; stigmas 3, 3 mm. long. 
Type inthe U.S. National Herbarium, no. 537,171, collected at San Martin de Loba 
and vicinity, Lands of Loba, Department of Bolfvar, Colombia, April or May, 1916, 
by H. M. Curran (no. 5). Curran’s no. 4, from the same locality, represents the 
staminate plant. 
This species is said to bear the same local name, ‘‘palo santo,’’ as the related Trip- 
laris lava, which comes from the same region. It is especially distinguished by its 
very broad leaves. 
Triplaris laxa Blake, sp. nov. 
Dioecious tree, 8 meters high, the trunk 10 cm. in diameter; branches stoutish, dull 
fuscous, striatulate, pilose with sordid, erect or ascending, soft hairs, in age glabrate; 
sheath bases persistent, very narrow, glabrate or sparsely strigose; petioles strongly 
flattened, obscurely puberulous, strigose-pilose on margin and sparsely beneath 
with sordid hairs, 1 cm. long; leaf blades 20 to 23 cm. long, 5 to 9.5 cm. wide, elliptic, 
acute to acuminate at each end, blunt at tip, scarcely undulate, subchartaceous, 
brownish green when dry, above evenly but rather sparsely pilose with dull ascending 
hairs, more densely short-pilose along the costa and the scarcely prominulous veins, 
beneath scarcely paler, similarly but more densely pubescent with looser hairs, those 
of the costa more appressed; lateral veins about 22 pairs, beneath prominulous, straight- 
ish, parallel, toward margin arched and anastomosing, the secondaries oblique, 
obscurely prominulous; pistillate inflorescences axillary and terminal, loose, simple, 
or 3-branched from near the base, up to 38 cm. long (including the 3 to 4 cm. long 
peduncle), densely and softly pilose with loosely ascending or spreading dull hairs 
and beneath these densely puberulous, rather loosely flowered; bracts ovate, acuminate, 
somewhat convolute, densely and dully pilose outside, glabrous and green inside, 5 to 
6 mm. long; pedicels densely pilosulous, about 3 mm. long, jointed near the middle; 
fruiting perianth 3.7 to 4 cm. long, scarious, the tube 1 cm. long, trigonous-urceolate, 
densely and dully pilose, the ascending hairs with slightly swollen bases; outer peri- 
anth segments spatulate-oblanceolate, obtuse, strigose-pilose on both sides, 3-nerved 
and reticulate, the two lateral veins evanescent above the middle, 2.7 to 3 cm. long, 
6 to 7 mm. wide above the middle; inner perianth segments ovate-lanceolate, obtuse, 
with clawlike base, reticulate-veined, sparsely strigillose below, borne at the base of 
the perianth tube and united to it only at extreme base, 5 to 6 mm. long, 1.7 mm. 
wide; achene olivaceous, glabrous, shining, trigonous-ovoid, mucronate by the per- 
sistent style base, slightly grooved on the sides, 8 mm. long, 4 to 4.3 mm. wide; stigmas 
3, 1.8 mm. long.

are said to be white.
