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. H901 Tarrosa, May, 26, 1912, near the seashore; Buluan Point, 

 For. Bur. 1828U 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.
