PlERARDIA DULCIS. 



Monoica, foliis obovatis. 

 Bua Choopa. Malay. 

 Sumatra. 



This is a middle-sized tree. Leaves crowded at the ends of the 

 branches, alternate, petiolate, obovate, or elliptic-obovate, 

 rounded at the top, with a short blunt acumen, entire, 

 smooth, flat; from eight to nine inches long. Petioles 

 thickened and jointed above and below. Stipules ovate, 

 deciduous. Racemes from the naked branches. Male and 

 female flowers in distinct racemes ; in the former the pedi- 

 cels are generally three-flowered; in the latter one-flowered. 

 Bracts small. 



Male. Perianth four-parted, spreading, j'^ellowish, tomentose 

 within, very slightly so without. Stamens eight ; filaments 

 very short; crw^Aers two-lobed. Ot;an/ abortive. 



Female. Perianth considerably larger than in the male, di- 

 . vided to the base into four long thick lobes ; sometimes there 

 is a fifth. Stamens none. Ovary subglobose, three-celled ; 

 cells two-sporous. Style one. Stigmas three, spreading, 

 fleshy, hispid. Berry subglobose, larger than a cherry, of 

 a yellowish colour, three-celled ; cells generally one-seeded. 

 Seeds enveloped in a white pulpy aril or tunic. The embryo 

 is inverse, with flat cotyledons in the centre of an ample 

 albumen. 



Obs. This species differs from that described by Roxburgh in 

 being monoecious, in the form of the leaves, and in the 

 colour of the fleshy aril. The Rambeh, of which Mr. Mars- 

 den has given a figure in his History of Sumatra, pi. vi. 

 p. 101. so nearly resembles this, that I think it can only be 

 a variety of the same. The Rambeh belongs to the penin- 

 sula
