FLORULA HONGKONGENSIS. 
GENTIANEÆ. 
Exacum Zel/ug, Hance, in Walp. Ann. Bot. Syst. vol. iii. p. 77. 
On the top of Mount Gough and Mount Victoria, flowering in July. 
GESNERIACER. 
1. ZEschynanthus Chinensis, Gardn. et Champ. in Kew Journ. Bot. 
vol. i. p. 328. 
Trailing over rocks and ravines, and rather local. 
2. Chirita Sinensis, Lindl. Bot. Reg. 1844, t. 59. 
Common in beds of ravines among the hills. The narrow-leaved 
variety mentioned by Hance (Kew Journ. Bot. vol. i. p. 141) grows 
abundantly in a ravine on Mount Gough. 
COoNYOLVULACEJ. 
1. Argyreea acuta, Lour.—Chois. in DC. Prodr. vol. ix. p. 333. 
Ravines of Mount Victoria. 
2. Ipomeea pentadactylis, Chois. Conv. Or. p. 89, et in DC. Prodr. vol. 
ix. p. 385. 
This plant agrees with Choisy's description, except that in the leaflets 
which are rather broader, and differs from the allied species by the - 
sepals all very blunt, the interior ones considerably longer than the 
others. It cannot however well be the West Indian Convolvulus tenui- 
Solius of Vahl, adduced by Choisy as a synonym to this species with the 
omission of Vahl's station. 
The J. fulvicoma mentioned by Hance, Kew Journ. Bot. vol. i. p. 176, 
is unknown to me. 
3. Jacquemontia violacea, Chois. in DC. Prodr. vol. ix. p. 179 (flore 
cxruleo).—Convolvulus iarthinus, Hance, in Walp. Ann. Bot. Syst. 
vol. iii. p. 113, ex charactere dato. 
This species, well known in our hothouses under the name of Chivol- 
vulus pentanthus, is quite naturalized in a ravine above the'town of 
Victoria. 
The volvulus pudicus, Hance, in Walp. Aun. Bot. Syst. vol. iii. p. 215, 
is not in the collections before me, but, from the character given, it 
cannot differ from the Æ. alsinoides, Linn., which is common all over - 
East India, as well as in most hot parts of the world. 
4. Cuscuta reflexa, Roxb.— Chois. in DC. Prodr. vol. ix. p. 454: var. 
VOL. V. 1
