STANDLEY—TROPICAL AMERICAN PHANEROGAMS, 121 
Diospyros sphaerantha Standley, sp. nov. 
Section Paralea. Tree with deciduous leaves; branches dark gray, bearing numerous 
large, pale gray lenticels, the branchlets slender, fulvous-puberulent and sparsely 
strigillose with slender white hairs: leaves (immature) alternate, on petioles 4 to 5 
mm. long, these strigillose and puberulent; leaf blades oblong or oblong-elliptic, 4.3 
to 8 cm. long, 2 to 3.3 cm. wide, obtuse at the apex, obtuse or rounded at the base, thin, 
drying black, sparsely strigillose on both surfaces with very short slender whitish 
hairs, the veins only slightly prominent in the young leaves; pistillate flowers very 
numerous, axillary, solitary or fascicled, the slender pedicels 5 to 10 mm. long, densely 
fulvous-puberulent; calyx at anthesis 3 cm. in diameter, spreading, lobed nearly 
to the base, the 5 lobes ovate, narrowly ovate, or ovate-oval, 5 to 8 mm. broad, acute 
to acuminate, thin, densely puberulent outside the base and thinly pubescent up- 
ward, within puberulent at the base but glabrous toward the apex; corolla globose- 
urceolate, about 8 mm. in length and diameter, densely fulvous-tomentulose outside, 
the lobes rounded at the apex, glabrous within; ovary globose, densely tomentulose, 
the style 1 to 1.5 mm, long. 
Type in the U. S. National Herbarium, no. 302159, collected in the foothills of the 
Sierra Madre near Colomas, Sinaloa, Mexico, July 13 to 20, 1897, by J. N. Rose (no. 
3194). 
Apparently Diospyros sphaerantha is closely related to D. roset and at first the writer 
believed that the specimens represented a single species. In the latter species, how- 
ever, the leaves are persistent, while in D. sphaerantha they are certainly deciduous. 
In the latter, too, the calyx lobes are not pubescent throughout and they are more 
acute. Furthermore, there is considerable difference in leaf outline. The proposed 
species is noteworthy because of the unusual development of the calyx at anthesis. 
A NEW STYRAX FROM PANAMA. 
There appeared a few years ago an elaborate monograph of the 
genus Styrax, by Miss Janet Perkins.'| Specimens collected in Panama 
by Mr. Pittier, however, can not be referred to any of the Central 
American or Colombian species described in that work, and are accord- 
ingly here described as new. 
Styrax panamensis Standley, sp. nov. 
A tree, 8 to 10 meters high; branches terete, the older ones grayish, the young ones 
slender, densely covered with short fulvous stellate hairs; leaves alternate, the 
petioles stout, 6 to 16 mm. long, fulvous-tomentulose; leaf blades oval or oval-elliptic, 
13 to 20 cm. long, 6 to 11 cm. wide, abruptly acuminate or attenuate at the apex, the 
acute tip 5 to 18 mm. long, rounded or rounded-cuneate at the base, chartaceous, 
entire, bright green and glabrate above in age, beneath densely covered with micro- 
scopic stellate gray hairs, the veins furnished with numerous coarser fulvous stellate 
hairs, the midvein stout, impressed above, the lateral veins 6 or 7 on each side, prom- 
inent beneath, impressed above, curvately joined near the margin, the veinlets con- 
spicuously reticulate; inflorescence axillary, of numerous densely flowered panicles 
3 to 4.5 cm. long, the rachis densely fulvous-tomentulose, the bracts and bractlets 
linear or subulate, densely stellate-tomentulose; flowers about 1 cm. long, on pedicels 
3 to 8 mm. long; calyx cupuliform, about 4.5 mm. high and 4 mm. in diameter, 
densely fulvous-tomentulose outside, sparsely so within, the margin truncate, very 
obscurely 5-denticulate; corolla 5-parted, the tube 1 mm. long, the lobes valvate, 
8 to 9 mm. long, 2 mm. wide, thick, densely covered outside with minute grayish 
appressed hairs, densely pubescent within; stamens 10, the free part of the filaments
