X Bractlets conspicuous, subulate, up to a line long. 



All parts glabrous ; leaves long-acuminate, 0. gracilis. 



X X Bracts subulate, usually persistent, but the bractlets very minute 

 if any. 



All parts (also the capsule) glabrous, 0. Mungos. 



Stems and petioles brown-pubescent ; leaves thick -membranous, whitish beneath ; cap- 

 sule glabrous, 0. argentea. 



As preceding, but leaves only pale-coloured beneath, the inflorescence more hispid- 

 pubescent ; capsule minutely hispid, 0. villosa.

1. O. GEACiLis, Kurz in Journ. As. Soc. Beng. 1872. 311. 

 Hab. Tenasserim, Attaran (Brandis). 



2. O. Mungos, L. AmEen. Acad. II. 127 ; Eoxb. Fl. Ind. I. 901 ; 

 DC. Prod. IV. 414 ; Miq. Fl. Ind. Bat. II. 166. 



Var. a. gentjii^a, capsule about 3 lin. across, emarginate, the lobes 

 somewbat acute. 



? Var. p. OETHOCAEPA, capsule about 2 lin. across, truncate at the 

 apex, the lobes blunt or almost truncate. 



Hab. Var. /8. only, Martaban hills, at 3000 ft. elevation (Dr. Bran- 

 dis). 



Dr. Brandis' specimens are not sufficient to enable one to make out 

 whether they should not rather form a distinct species. The true Linnean 

 species is a sea-shore plant, growing chiefly in the beach-forests, most pro- 

 bably also growing along the Burmese coasts. 



3. 0. AEGENTEA, Wall. Cat. 6229 ; Walp. Eep. II. 508. 



Hab. Chittagong ; Arracan, on sandstone rocks in the tropical forests 

 of Boronga island. — Fl. Fr Octob. 



Probably not sufficiently distinct from O. canescens, Bl.

 Syst. III. 523 ; O. trichocarpa, Bl. Bydr. 977 ; Miq. Fl. Ind. Bat. II. 178).
