STANDLEY—TROPICAL AMERICAN PHANEROGAMS. 119 
of the five species, M. intricata and M. albens, are represented in the National Her- 
barium by specimens. The last mentioned species, until recently unrepresented, 
was collected on the Cerro de Picacho, Oaxaca, in July, 1914, by ©. A. Purpus (no. 
7176). 
Maba verae-crucis Standley, sp. nov. 
Branches slender, the older ones gray, the branchlets at first canescent but later 
glabrate; petioles 3 mm. long, densely covered with short appressed hairs; leaf blades 
rhombic-obovate or elliptic-oblanceolate, 5.5 to 8.5 cm. long, 1.8 to 4 cm. wide, nar- 
rowed at both ends, acute or acuminate at the apex, acute at the base, thin, green, 
concolorous, the upper surface at first canescent but finally glabrate and obscurely 
papillose, the lower surface sparsely strigose, minutely pellucid-punctate, the mid- 
vein impressed above, prominent beneath, the lateral veins and the veinlets weak 
and inconspicuous; flowers not known; fruits solitary, axillary, on very stout pedicels 
3 to 4 mm. long; fruiting calyx 15 mm. broad, shallowly 3-lobed, the lobes broadly 
rounded, densely sericeous and smooth inside, coarsely rugose and sparsely sericeous 
outside; fruit subglobose, 12 to 16 mm, in diameter, 6-celled, glabrate at maturity, 
but sericeous when young; mature seeds not seen. 
Type in the U. S. National Herbarium, no. 569278, collected at Catemaco, Veracruz, 
Mexico, altitude 300 meters, April 26, 1894, by E. W. Nelson (no. 429). 
This proposed species appears to be related to Maba acapulcensis, but it differs in 
its smaller fruit and shallowly lobed calyx, and it does not have the hirtellous leaves 
ascribed to the latter. 
Diospyros blepharophylla Standley. 
Diospyros ciliata A. DO. in DC. Prodr. 8: 229. 1844, not D. ciliata Raf. 1836. 
Diospyros palmeri Eastw. Proc. Amer. Acad. 44: 604. 1909. 
The species was described from fruiting material collected in the vicinity of San 
Dieguito, San Luis Potosi, Mexico, early in June, 1905, by Dr. Edward Palmer (no. 
631). In 1907 Dr. Palmer made two additional collections of the same species in the 
vicinity of Victoria, Tamaulipas (nos. 116 and 369), These are exactly like the one 
from San Luis Potosf. One of them (no. 116) bears very young fruits, upon some of 
which the corolla still persists. This is globose-urceolate, about 5 mm. long, glabrous 
outside near the base, but puberulent above. The corolla lobes are oval, rounded at 
the apex, glabrous on the inner surface, but densely pubescent on the outer. The 
species is a member of the section Danzleria, to which Diospyros virginiana also 
belongs, but there is little resemblance in the general appearance of the two species. 
Diospyros rosei Standley, sp. nov. 
Section Paralea. Tree with persistent leaves; branches covered with grayish 
brown bark having numerous lighter colored lenticels, the branchlets slender, brown- 
ish yellow, puberulent when young but soon glabrate; leaves alternate, on stout petioles 
6 to 8 mm. long, these finely puberulent or in age glabrate; leaf blades oblanceolate- 
oblong or rarely oblong-obovate, 6 to 14.5 cm. long, 3 to 4.5 cm. wide, rounded at the 
apex, cuneate or rarely only obtuse at the base, subcoriaceous, green or grayish green on 
the upper surface and glabrous except along the puberulent veins, minutely puberu- 
lent beneath, especially along the veins, the midvein very prominent, the lateral veins 
5 to 7 on each side, irregularly spaced, laxly anastomosing near the margin, the vein- 
lets very numerous, prominent, and reticulated; flowers not known; fruit axillary, the 
pedicels solitary or fascicled, 5 to 15 mm. long, stout, puberulent; fruiting calyx 3.5 
to 4. cm. broad, puberulent throughout or finally glabrate, lobed nearly to the base, 
the 5 (rarely 4) lobes ovate or oval-ovate, 6 to 10 mm. broad, acute or acutish, promi- 
nently veined; fruit depressed-globose, 8 to 10-celled, about 2.5 cm. in diameter, 
densely pubescent when young with short appressed hairs, glabrate in age; mature 
seeds not seen.
