Hedycarpus Malayanus. 

 Bera Tampui. Malay, Sumatra. 



PIERARDIA. Roxb. 



Perianthium 4-partitum, Stamina octo, brevia. Ovarium 

 3-loculare, loculis disporis. Stigma trifidum. Bacca corticata, 

 trilocularis, loculis 1 — 2-spermis. Semina arillo sapido tunicata. 

 Embryo inversus albumine inclusus. 



ArboreSf Jloribus racemosis, foliis alternis simplicibus, 



PlERARDIA DULCTS. 



Monoica, foliis obovatis. Bua Choopa. Malay. Sumatra. 



" 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. Marsden has 

 given a figure in his History pf Sumatra , pi. wi.p. 101, so nearly 

 resembles this, that I think it can only be a variety of the same. The 

 Rambeh belongs to the peninsula of Malacca, and is unknown 

 at Bencoolen ; while the Choopa, which is abundant at the latter 

 place, is not found in the former. The racemes of the Rambeh 

 are longer and the fruit smaller than in the Choopa ; but a com- 

 parison and examination of the two would be necessary to ascer- 

 tain whether there are any essential differences, and I have not 

 had an opportunity of doing this.'* 



LEUCONOTIS. 



Tetrandria Monogynia. N. O. Apocine(B. Br. 



Calyx inferus, 4-partitus. Corolla tubulosa, superne angus- 

 tior, limbo 4-lobo. Stamina 4, inclusa, laciniis corolla alterna. 

 Ovarium simplex, biloculare, loculis disporis. Stylus 1, breyis. 

 Stigma annulatum, apice conico. Bacca 1 — 3-sperma. Semina 

 exalbuminosa, embryone inverso. 



Frutex lactescens, foliis oppositis exstipularibus, Jloribus dicho- 

 tome corymbosis axitlaribus. 



Leuconotis anceps. 



Akar Morai. Malay. Sumatra. 



" This singular plant belongs without doubt to the family of 

 the ApocynecB, with which its general appearance and habit 

 entirely correspond. It agrees with Cerbera in having exalbumi- 

 nous seeds ; but its ovary is simple hke that of Carissa ; it will 

 therefore hold an intermediate place between these two genera." 



MYRMECODIA. 



Tetrandia Monogynia. N. O. Rubiacea. 

 ^ Calyx subinteger. Corolla quadrifida tubo intus ad insertio- 

 ■ nem staminura piloso. Stamina quatuor, corolla breviora.
