midrib, as prominent as the basal ones, somewhat ascending, 
anastomosing, the reticulations distinct; petioles 5 to 8 mm long, 
pubescent when young, ultimately glabrous. Flowers on defol- 
iated branches, axillary, several in each axil, white, the pedicels 
densely pubescent, stout, 3 to 4 mm long. Calyx obconic, about 
5 mm long, 4 mm in diameter, the limb produced 1.5 to 2 mm 
above the ovary, very broadly and obscurely 5-toothed. PetaL 
5 (rarely 4) , on the type 4,5 cm long (on other specimens referred 
here 3.5 to 4 cm in length) , 2 mm wide below, free, narrowed 
above, cinereous-pubescent. Stamens 16 or 17, ds long as the 
petals; filaments villous in the lower one-half or one-third, not 
curved-gen iculate; anthers 10 mm long. Style glabrous, as long 
as the petals; stigma globose, 2 mm in diameter. Fruit ovoid or 
ellipsoid, cinereous-puberulent, nearly 2 cm long.

A species manifestly allied to Alangium salviifolium (L. f.) Wangerin, 
differing in its very much longer, 5-merous flowers, fewer stamens, and in 
its filaments which are not curved-geniculate near the base, but which are 
more or less pilose for the lower one-third or one-half, and very much 
longer than in A. salviifolium. 
I do not hesitate to refer here Cuming 1716 from Samar, which is cited 
by Wangerin" under Alangium salviifolium, (L. f.) Wangerin, subsp. 
hexapetalum (Lam.) Wangerin. Our specimen of Cuming's plant has 6- 
merous flowers with the petals 4 cm in length, characters by which I have 
distinguished the species above described. Alangium salviifolium var. hex- 
apetalum, as described by Wangerin, has 6-merous flowers and petals 2 to 
2.5 cm in length. 
In Cagayan Province the species is known as apitan; in Camarines as 
bunglas and malatapay. 
This form has previously been considered by Philippine botanists^ to 
represent Alangium octopetalum Llanos, F.-Villar and Vidal reducing 
that species to Alangium lamarckii Thwaites. In working over the iden- 
tifications of the species described by Blanco, I followed F.-Villar in re- 
ferring A. octopetalum to A. lamarckii. The description of Alangium octo- 
petalum Llanos, for Blanco definitely states that it was described by Llanos, 
is very short and incomplete, but a careful examination of it shows con- 
clusively that it can not be the same as Alangium salviifolium, or A. lon- 
giflorum. The description calls for a plant with 8 petals and from 9 to 
11 stamens, with no style or stigma; if Llanos correctly described his plant, 
then the last character would exclude Alangium octopetalum from the genus.
