320 MERRILL. 



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. Petals 

 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, as 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 5- 

 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 Alangiuvi 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, wit*h no style or stigma; if Llanos correctly described his plant, 

 then the last character would exclude Alangium octopetalum from the genus.
