1376.] S. Kurz — A Sketch of the Vegetation of the Nicobar Islands. 121 



47. Abroma AUGUSTA, L. — Nankowry (Novara 154 ; Jelinek 172 — 

 Jcomopoang, inc.). 



48. Visenta Ikdica, Houtt. — Bather frequent in the tropical forests 

 of Kamorta ; also Nankowry (Novara 168 ; Jelinek 168 — diam, inc.). 



N. B. Pterospermum diversifolium, Bl. (Hf. Ind. Fl I, 367) is 

 reduced by Miquel (111. Fl. Arch. Ind. 84) to a synonym of P. acerifolium, 

 and he includes in this species P. fuscum, Korth also. — Pt. Blumeanum, 

 Korth., (Kurz in Journ. As. Soc. Beng. 1874, 120) is identified by Miquel 

 (1. c.) with P. Javanicum, Jungh. in Tydsch. Natuurk. Gesch. en Physiol. 



VII. 306 (Miq. 111. Arch. Ind. 88). In Journ. As. Soc. Beng. 1874, 122, 1 

 have placed Buettneria crenulata, "Wall, in Hf . Ind. Fl., amongst the doubt- 

 ful species. I have since come across the specimens of Wallich's B. crenu- 

 lata, which I see have been correctly placed by me in B. aspera, Coleb., from 

 which it differs in no respect. But B. echinata, Wall. Cat. 1150, of 

 which I have seen nothing but fragments, is a different plant, and I now 

 believe that Masters drew up his description chiefly from this species, the 

 name of which must be restored. 



TILIACEJE. 



49. Grewia calophylla, Kurz. — Not unfrequent in the tropical 

 forests of Kamorta. 



N. B. Grewia Miqueliana, Kurz in Flora 1872, 398 (with which 

 Maingay's No. 244. is identical), is really a distinct species from the above, 

 differing not only in the characters already mentioned by me but also in 

 having fruits only half the size. 



50. Triumpetta rhomboidea, Jacq. — A narrow-leaved variety of 

 this occurs here and there in the dry grass-heaths and around the huts of 

 Kamorta. 



N. B. T. hit/mifusa, Hassk., = T. procunibens, Forst. T. trilocularis, 

 Roxb., is more likely a form of T. semitriloha, L. 



51. Trichospermum Javanicum, Bl. ; Clos. in Ann. sc. nat. 4 ser. 



VIII, 265 (Bixagrewia Nicooarica, Kurz in Trim. Journ. Bot. 1875. 325. 

 t. 169). — Not unfrequent in the tropical forests of Kamorta. 



N. B. If Loureiro's Thrixspermum (Orchidese), in a corrected form, 

 obtains acceptance amongst botanists, as indeed Reichenbach fil. has already 

 proposed, Asa Gray's Diclidocarpus will also supersede Blume's generic name. 

 Chartacalyx accrescens, Mast, in Hf . Ind. Fl. I. 382, is in my opinion only a 

 species of Actinophora. The difference in the calyx is not of generic value, 

 and as regards the stalked ovary, we should bear in mind, that the ovary 

 of Actinophora is globose and constricted at base, and hence that the character 

 of the stalk is one of development only. Pentace triptera, Mast, is only a 

 3- or rarely 4-celled and -winged variety of P. polyantha, Hassk.
