Note. — This ^enus was first published by Blume in his Bijdrageti 

 (p. 600) as Myparosa^ and iu that work he published only the single 

 species R, ccebia. In a footnote to the preface of his Flora Javae 

 (p. viii), the same author referred to the genus (apparently by inadver- 

 tence) as Ri/piiri<i instead of liyparosa ; and the name Byparia has 

 been adopted by most subsequent autliors. Blume regarded the genua 

 as Euphoibiaceous, in which view he was followed by Endlicher (Gen. 

 5836), Ha.s.skarl (PI. Jav. Rar., p. 267), and Baillon (Etud. Euph., 

 p. 339 . Mull. Arg. (in DC. Prod. XV, ii., p. 12G0) excluded the genus 

 from Enphorhiaceae ; and, in their Genera Plantarum, the late Mr. 

 Bentham and Sir J. D. Hooker, ( G. P. iii., 257), also exclude it; but, 

 •having seer, no specimens either of it or of Bergaviia, they make no 

 suggestion as to the true position of Ri/parosa or of the relation of 

 Bergsmia to it. Kurz (Journ. Bot. for 1873, p. 233, and For. El. 

 Burm. I. 76 ) was the first to refer liyparosa to Bixinese. But Kurz 

 made the mistake of describing in the latter work, as " Byparia caesia, " 

 a plant which atrrees neither with Blume's dt^scription nor with liia 

 specimens of Bypurosa cai'sia. The name of Kurz's plant I have there- 

 fore altered to H. Kurzii. In IS-iS, Blume published, in Rumphia IV, 

 p. 23, t. 178 C, fig. 2, a nevv genus called Bergsinia which, as Kurz also 

 pointed oat (Journ. of Bot. for 1873, p. 233), is nothing more or less 

 than his older Bypnrosa. Only one species ( /?. javanica) was known to 

 Blume. To this Miquel added iFl. Ind. Bat. Suppl. 389) two species, 

 namely, B. Sumatrana and B.? acuviinata. I have seen neither of 

 these ; but the cymose inflorescence of B. Sumatrana leads me to believe 

 that it must be a ffi/^i^jtocajpfw, while the second {B. ? acuminata) was 

 referred doubtfully to /ye?\9«Hwa by its author himself. The collections 

 brought, within the past year or two, from Perak by the collectors of 

 the Calcutta garden contain copious suites of specimens of Bypnrosa 

 and, from an examination of these, I have no doubt that Byparusa be- 

 longs to Bixineae, and that Bergsmia must be I'educed to it. Besides 

 the seven species described below, there are in the Calcutta Herbarium 

 imperfect materials belonging to several additional .species from Perak, 

 and to some from Sumatra. Wall. Cat. No. 7847 B. (from Penang), and 

 Beccari's No. 702 (from Sumatra), are also clearly species of Ryparosa.
