in Ihe delta of the Menam (Pierre). River Menam, near Bangkok (Schomburgk, 

 n. 151). The type-specimen of this species (a single example, and a somewhat 

 scrappy one) is in Herb. Kew. ; and still bears on its original label the name 

 (wriiten in pencil) of «Calophyllum inophyllum.» In the Index Keivensis, its 

 habitat is erroneously stated to be Guiana (where Schomburgk afterwards 

 collected plants).

569. Dipterocarpus alatus Roxb. — Widely distributed in Siam, according 

 to Pierre (Fl. For. Coch., t. 212 [fasc. XIV, Août, 1889]). — F K C. VII, p. 43 

 (n. 742); jungle near the Sarlakpet creek. 



570. Dipterocarpus incanus Roxb. — Island of Junk Seylan (Curtis, 

 n. 2926). 



571. Dipterocarpus insularis Hance. — Siam (Pierre, n. 1421). 



572. Dipterocarpus obtusifolius Miq. — In the Bassac région (Harm and, 

 ex Pierre, Fl. For. Coch., t. 223 [1889]). Gregarious on latérite and sandy 

 soils. 



573. Dipterocarpus tuberculatus Roxb. — Gregarious, forming extensive 

 forests at the base of the lower hüls of Siam. The tree bas been described as 

 having leaves rounded at the base, a character which Pierre bas noticed in 

 many Siamese spécimens (Fl. For. Coch., fasc. XIV, t. 218). General ly 

 speaking, however, the leaves are cordate at the base, though cerlainly each 

 half is rounded. 



The latest account of the Dipterocarpacese is an enumeration of the species of 

 the family by Sir D. Brandis, iu Jottrn. Linn. Soc. XXXI (Nov. 1895). A few 

 corrections are required as to remarks on Siamese species of Dipterocarpus. The 

 author mentions the occurrence of D. incanus at «Tongkah (Siam), on the east 

 coast of the Malay peninsula in its norlhernmost extremity.» This locality is the 

 Malay vernacular name for the island of Junk Seylan; which is, however, at 

 the northern extremity of the west, not of the east, coast of Lower Siam. In 

 the memoir cited the distribution of D insularis is given as Cambodia and 

 Cochinchina. Pierre's record of the occurrence of the tree in Siam is overlooked.
