oct. 4, 1923 STANDLEY: NEW PLANTS FROM SALVADOR 365 
their bracts compressed, 2—2.5 cm. long, pink, thin, loosely appressed and 
overlapping for half their length, coarsely and loosely lepidote; sepals distinct, 
2 cm. long, glabrous; corolla violet, exceeding the bracts 2—2.5 em.; stamens 
conspicuously exceeding the corolla, the style long-exserted. 
Type in the U. S. National Herbarium, no. 1,137,360, collected on the 
Voledn de San Vicente, Salvador, altitude about 1500 meters, March 8, 1922, 
by Paul C. Standley (no. 21588). Standley 21588 from the same locality 
represents the same species. 
Related to T. digitata Mez and T. flabellata Baker, but readily distinguished 
by the coarse, loose pubescence of the leaves and bracts. The pubescence 
is similar to that of 7’. streptophylla Scheidw., but less coarse, and the leaves 
are not dilated at the base as in that species. 
Dioscorea salvadorensis Standl., sp. nov. 
Stems scandent, slender, very minutely and sparsely hirtellous or glabrate, 
with elongate internodes; petioles mostly 2.5-3.5 em. long, pubescent like the 
stems; leaf blades about 9 cm. wide and 7-9 em. long, cordate at base, with 
a broad rounded sinus, 3-lobed to the middle or nearly to the base, the lateral 
lobes somewhat falcate, obtuse to acuminate, the terminal lobe obtuse to 
acuminate and cuspidate-mucronate, glabrous on the upper surface, beneath 
minutely muricate-hirtellous along the nerves; staminate spikes solitary, 
long-pedunculate, simple, 15-22 cm. long or longer, the rachis glabrous, 
slender, the flowers sessile ; bractlets lance-attenuate, shorter than the flowers; 
perianth segments narrowly oblong, obtuse, 2mm. long, glabrous; stamens 3, 
two-thirds as long as the perianth segments, the anthers oblong, the filaments 
broad, slightly dilated toward the base, nearly equaling the anthers. 
Typein the U.S. National Herbarium, no. 1,151,507, collected on the Cerro 
de la Olla, on the Guatemalan frontier, near Chalchuapa, Salvador, in 1922, 
by Dr. Salvador Calderén (no. 1020). Also collected at La Cebadilla, 
Departamento de San Salvador in 1922, Calderén 1238. 
Among the Central American species of Dioscorea this is easily recognized 
by its trilobate leaves. 
Agave calderoni Trelease, sp. nov. 
Of the group Guatemalenses. Acaulescent, not cespitose (?). Leaves green 
or very lightly and evanescently glaucescent, oblanceolate-oblong, acute, 
smooth, about 15 cm. wide and 80 cm. long; spine brown or somewhat tinged 
with purple at base, slightly glossy, elongate-conical or subacicular, straight, 
slightly flattened above and involutely grooved with acute edges below the 
middle, narrowly decurrent for about twice its own length, intruded into the 
green tissue dorsally, about 40 mm. long and 5 mm. thick; teeth chestnut- 
colored, 5-10 mm. apart, frm, but small (scarcely 1 mm. long), triangular, 
lenticularly widened into the nearly straight margin. Inflorescence panicu- 
late, apparently with rather short branches and closely bunched flowers, the 
rather thick and short (5 mm.) pedicels densely invested by short broad 
papery bracts. Flowers bright orange, about 40 mm. long; ovary 15-20 mm. 
long, about equaling the perianth, oblong; tube broadly conical, scarcely 5 
_mm. deep; segments 10-15 mm. long, shorter than the ovary; filaments 
inserted nearly in the throat, about 40 mm. long. Capsules unknown; not 
known to be bulbiferous.
