(when it is covered with the bases of the leaf-stalks ?). Leaves about 1 m in 
length; leaflets in the lower portion of the leaf markedly fascicled and pointing 
in different directions, more regularly set and more approximate in the terminal 
part, rigid, narrowly but distinctly lanceolate, with dull, not shining, surfaces, 
when dry. Fruiting perianth distinctly cyathiform, covering one-fourth part of 
the entire fruit, the corolla slightly more than twice as long as the calyx, the 
petals with a narrow and slightly scarious margin. Fruit ovoid-oblong, 15 to 18 
mm long, about 9 mm thick, apparently black when quite mature, distinctly mu- 
cronate; seed 10 to 12 mm long, 5.5 to 6 mm thick.

Batanes Islands, Batan, Santo Domingo de Basco, Bur. Sci. 381/1 Fenix, June, 
1907, growing along mountain streams. 
This is one of the largest species of the genus, apparently related to Pinanga 
insignis Becc., but the present species has larger, equidistant, and always solitary 
(never geminate) leaflets, and larger fruits.
