06 MateriaU for a Flora of the Malayan Teninsula. 



1 have followed Mr. Clarke in redncing P. rejiexa, Bl. here, a$ I can find no 

 tangible character to separate it. P. reflexa is said to have white tumid petals not 

 toothed on the margin, while typical P. pulvendenta is described as having red 

 petals with a single tooth on each margin. The union of the two species was 

 suggested by Naudiu. 



15. Pachycentria, Blume. 



Glabrous, often scandent shrubs, with cylindric or obscurely angled, 

 pulverulent branches. Leaves somewhat fleshy, oblong or ovate-lanceo- 

 late entire or obscurely crenulate. Flowers small, rose-coloured, 

 corymbose, the pedicels 2-bracteolate, 4-merous. Calyx-tube ovoid or 

 turbinate, the part beyond the ovary angular, constricted below the 

 obscurely 4-toothed mouth. Petals ovate or oblong, subacute or acumi- 

 nate. Stamens 8, equal ; anthers linear-oblong or subalate, rostrate at the 

 apex and minutely 1-pored ; the connective not produced at the base, in- 

 appendiculate in front but minutely spurred at the back. Ovary 

 adherent beyond its middle, 4-celled, its apex free, conic, angled; style 

 filiform, the stigma obtuse or capitate. Berry globose, crowned by the 

 limb of the calyx. Seeds dimidiately obovoid, the raphe lateral. 

 DiSTRiB. About 12 species, all Malayan. 



Pachycentria tubercdlata, Korth. Ver. Nat. Gesch. Bot. 246, t. 63. 

 Epiphytic ; branches as thick as a swan's quill, glabrous below but 

 with rusty scurf near the apices, the bark pale ; the roots bearing 

 woody tubercles. Leaves somewhat fleshy, narrowly elliptic-oblong, 

 subacute, narrowed at the base, the edges entire, 3-nerved ; length 

 2-5_4,-5 in. ; breadth 'Q-l^S in. ; petioles •15-*2 in. Panicles terminal 

 or axillary, pedunculate ; the branches spreading, cymose, 2-2'5 in. 

 long and as wide. Flowers •25 in. long, the pedicels shorter. CalyX' 

 tube campanulate, the mouth truncate, obscurely 4-lobed. Petals 4, 

 lanceolate. Stamens 8, equal, shortly spurred at the base behind. 

 Fruit globular, glabrous, '15 in. in diam. Blume, Mus. Bot. Lugd.
