THE FLORA HONGKONGENSIS. 103 
*Rhaphiolepis 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 pinnata, Pers. (=Bryophyllum calycinum, Salisb.; Benth. 
Fl. Hongk. 127.) 
Mr. Dalzell has described (Hook. Kew Journ. Bot. iv. 346), 
under the name of Kalanchoe Ritchieana, a plant which evidently 
renders necessary the suppression of Bryophyllum. This species 
has been accidentally overlooked by Drs. Hooker and Thomson 
in their recension of Indian Crassulacee (Journ. Linn. Soc. 
ii. 90). . 
*Altingia chinensis, Oliv. in Benth. and Hook. f. Gen. Plant. i. 669. 
(=Liquidambar chinensis, Champ. ; Benth. Fl. ar 132.) 
*Jambosa, Syzygium, and Acmena, 
recognized as genera in the ‘Flora Hongkongensis,’ are in the 
* Genera Plantarum’ (i. 718) reduced to Eugenia—the first as a 
separate section, the two latter to the section Syzygium. 
*Melastoma repens, Desr., 
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 * Genera Plantarum" (i. 
745) to Osbeckia, where DeCandolle had previously placed it. I 
have, however, shown (Seem. Journ. Bot. vii. 296) that this is a 
mistake, the plant agreeing in all characters both of flower and 
fruit with the genuine species of Melastoma. 
*Barthea chinensis, Hook. f. in Benth. and Hook. f. Gen. Plant. i. 
751. (=Dissocheta Barthei, Hance in Benth. Fl. Hongk. 115.) 
*Blastus cochinchinensis, Lour. Fl. Cochinch. ed. Willd. ii. 643 ; Seem. 
Journ. Bot. i. 281; Hook. f. in Benth. and Hook. f. Gen. Plant. i. 
/52. (=Anplectrum parviflorum, Benth. Fl. Hongk. 116.) 
*Blastus Hindsii, 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
