sericeous scale at its base. Male flower ; filaments united in a column,

 staminodes 5, alternate with the petals. Ovary 1-celled, with 1 to 3, 

 biovulate, parietal placentas. Stigmas 2 to 3, sessile, broad, emarginate. 

 Fruit baccate with little pulp ; the pericarp coriaceous, tomentose. 

 Seeds 1 or 2, sub-globular, smooth. 



Note. — This genus was first published by Blume in his Bijdragen 

 (p. 600) as Byparosa, and in that work he published only the single 

 species B. ccesia. In a footnote to the preface of his Flora Javae (p. 

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

 tence) as Byparia instead of Byparosa ; and the name Byparia has 

 been adopted by most subsequent authors. Blume regarded the genus 

 as E uphorbiaceous, in which view he was followed by Bndlicher (Gen. 

 5836), Hasskarl (PL Jav. Ear., p. 267), and Baillon (Etud. Euph., p. 

 339). Mull. Arg. (in DC. Prod. XV, ii., p. 1260) excluded the genus 

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

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

 having seen no specimens either of it or of Bergsmia, they make no 

 suggestion as to the true position of Byparosa or of the relation of 

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

 Burm. I. 76) was the first to refer Byparosa to Bixineae. But Kurz 

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

 a plant which agrees neither with Blume's description nor with his 

 specimens of Byparosa caesia. The name of Kurz's plant I have there- 

 fore altered to B. Kurzii. In 1848, Blume published, in Rumphia IV, 

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

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

 than his older Byparosa. Only one species (B. javanica) was known to 

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

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

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

 that it must be a Hydnocarpus, while the second (B. ? acuminata) was 

 referred doubtfully to Bergsmia 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 Byparosa 

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

 longs to Bixineae, aud that Bergsmia must be reduced 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 Byparosa.
