long, 2.5 to 8 cm wide, shining on both surfaces, the lower 
somewhat paler than the upper, the apex blunt-acuminate, the 
base acute or rounded ; nerves about 12 on each side of the midrib, 
spreading, distant, prominent on the lower surface, looped- 
anastomosing, the reticulations very lax, distinct; petioles 3 to 
8 mm long. Female flowers 5-merous, axillary, in few-flowered 
fascicles, densely fulvous-pubescent. Calyx in bud densely 
pubescent, the sepals oblong-lanceolate, longitudinally folded or 
plicate, the reflexed margins very prominently horizontally un- 
dulate-plicate, free nearly to the base. Corolla cylindric, 6 mm 
long in bud, densely pubescent. Ovary densely appressed-hir- 
sute, narrowly ovoid, 5- or 6-celled. Young fruit narrowly 
ovoid, obtuse, pubescent, about 1 cm long (very young) quite 
free from the accrescent, involucre-like calyx. Accrescent 
calyx-lobes ovate, somewhat foliaceous, coriaceous, slightly 
pubescent, 2.5 cm long, free except at the very base, folded back 
longitudinally and also prominently horizontally undulate- 
plaited, forming an ovoid involucre surrounding but free from 
the fruit, this accrescent calyx 5 cm in diameter when spread.

Foxworthy, DeMesa, & Villamil, May 11, 1912 (type), in hill forests, altitude 
about 120 meters, specimens with young fruit: District of Cotabato, Cabla- 
can, For. Bur. 1J,901 Tarrosa, May, 26, 1912, near the seashore; Buluan Point, 
For. Bur. 1828J+ Miranda, May 27, 1912, the last two with young flowers. 
A very striking species, well characterized by its accrescent calyx which 
is quite free from the fruit, and which is longitudinally folded or plicate 
and at the same time very prominently horizontally undulate-plicate. Its 
leaves are very similar to those of our common Diospyros pilosanthera, to 
which, however, it is not otherwise at all closely allied.
