THE PLOBA HON&KONGEirSIS. 15 



*Rhaplxiolepis indica, Lindl. 



Being the same as Opa Metrosideros of Loureiro, Dr. Seemann 

 proposes (Journ. Bot. i. 281) to revive this generic name, on the 

 score of priority. But the other species of Opa described by 

 Loureiro is a Eugenia, so that the proposed change, which would 

 create four or five superfluous synonyms, is opposed to all sound 

 principles of nomenclature, a genus composed of such hetero- 

 geneous elements having no claim to resuscitation. 



•Kalanchoe piimata, Pers. (=BryophylIum calycinuin, Salisb.; Benth. 

 Fl. Hongk. 12?.) 

 Mr. Dalzell has described (Hook. Kew Journ. Bot. iv. 346), 

 under the name of Kalanchoe lUtchiecma, a plant which evidently 

 renders necessary the suppression of Bryophylltim. This species 

 has been accidentally overlooked by Drs. Hooker and Thomson 

 in their recension of Indian Orassulaceae (Journ. Linn. Soc, 

 ii. 90). 



*Altingia chinensis, Oliv. in Benth. and Hook. f. Gen. Plant, i. 669. 

 (=Liquidambar chinensis. Champ. ; Benth. Fl. Hongk. 132.) 



*Jambosa, Syzygitun, and Acmena, 



recognized as genera in the ' Flora Hongkongensis,' are in the 

 ' Genera Plantarum' (i. 718) reduced to Mugenia — the first as a 

 separate section, the two latter to the section Byzygivm. 



*]yielastoina repens, Tiesr., 



which, with a few other species, constitutes the genus Aste- 



rostoma of the late Prof. Blume (Mus. Bot. Lugd.-Bat. i. 51), 



is transferred by Dr. Hooker in the ' G-enera Plantarum ' (i. 



745) to Osbeckia, where DeCandoUe had previously placed it. I 



have, however, shown (Seem. Journ. Bot. vii. 296) that this is a 



mistake, the plant agreeing in aU characters both of flower and 



fruit with the genuine species of Melastoma. 



*Baxthea chinensis. Hook. f. in Benth. and Hook. f. Gen. Plant, i. 



751. (=Dissochseta Barthei, Hance in Benth. Fl. Hongk. 115.) 



*Bla;Stus cochinchinensis, Lour. Fl. Cochinch. ed. Willd. ii. 643 ; Seem. 

 Jmirn. Bot. i. 281 ; Hook. /. in Benth. and Hook. f. Gen. Plant, i. 



752. (=Anplectruin parviflomm, Benth. Fl. Hongk. 116.) 



♦BlastusHindsii, mihi. (=Oxyspora? pauciflora, Benth. Fl. Hongk. 116.) 

 As this has ample, lax, many-flowered panicles (in some fine 

 specimens gathered by me, in September 1866, in the forest at the 

 Tsing-yune pass, in the province of Kwang tung, they were fre- 

 quently above a foot in length), whilst the preceding has the
