SIMARUBE^E. VI. HARRISONIA. DIPTEROCARPE^. I. DIPTEROCARPUS. 



at the apex, 4-celled, each cell containing 1-ovula. Style rising 

 from between the lobes of the ovary, divided in 4 at the base, but 

 at length simple, terminated by a blunt stigma, which is obscurely 

 4-furrowed. Fruit baccate, globose, 4-lobed, 4-celled ; each cell 

 containing one seed, sometimes sterile. Seed subglobose, pendu- 

 lous from the apex of the cell, having a double integument, 

 marked at the hilum. Embryo green, with twisted cotyledons, 

 without albumen. A shrub, with alternate leaves, those at the 

 top of the branches are simple, the rest are ternate ; leaflets 

 toothed at the base, lateral ones smallest, and unequal. Pe- 

 duncles axillary, solitary, simple at the base, but divided at the 

 top into a corymb ; pedicels furnished with twin bracteas. 

 Prickles scattered on the branches, rarely twin at the base of the 

 petioles.

ORDER LXI. DIPTEROCA'RPE^E (plants agreeing in 

 character with Dipterocarpus). Blum. fl. jav. vol. 1. p. 1. 

 Guttiferarum sectio Colebr. in asiat. res. 12. Tiliaceae, Spreng. 



Calyx of 5 leaflets or segments, for the most part concrete at 

 the base (f. 125. a.), rarely free, valvate or imbricate in aestiva- 

 tion. Petals 5 (f. 125. &.), hypogynous, joined into a subro- 

 tate corolla, twisted in sestivation (f. 125. d.). Stamens usually 

 indefinite (f. 125. c.), hypogynous, free or connected a little at 

 the base, sometimes irregularly polyadelphous ; filaments di- 

 lated at the base; anthers erect, elongated (f. 125. c.), awl- 

 shaped, 2-celled, bursting at the apex by 2 pores. Ovary one, 

 free, few-celled ; cells 2-ovulate. Ovulse pendulous, fixed to the 

 inner angle of the cells. Style 1, undivided, crowned by a sim- 

 ple stigma. Fruit girded by a thick corticate pericarp (f. 125. 

 e.~), and by a more or less extended calyx (f. 125. f.), 1-celled 

 and 1 -seeded from abortion, 3-valved, indehiscent. Seeds with- 

 out albumen, umbilicate at the base. Embryo with chrysalis- 

 like contortuplicate, or unequally and obliquely incumbent coty- 

 ledons, and an inferior or superior radicle. Elegant trees, full 

 of resinous turbid juice. Leaves stalked, alternate, entire, 

 feather-nerved, articulately inserted, involute before expansion. 

 Stipulas oblong, deciduous, convolute, as in Ficus, and therefore 

 the branches are terminated by a conical acumen, which at length 

 divides and falls off. Peduncles racemose, axillary, near the tops 

 of the branches, or constituting a terminal racemose panicle. 

 Flowers yellow or white, mixed with red. This order agrees 

 with Oclmacece in the anthers being terminated by a beak, and 

 opening by two pores, by their unilocular fruit, by the absence 

 of albumen, and lastly by their alternate leaves, furnished with 

 membranous caducous stipulas. The order is remarkable for 

 containing the camphor tree of Sumatra, and many others of the 

 species produce camphor, although of an inferior quality.
