THE FLORA HONGKONGENSIS. 105 
In woods and thickets. Common on the adjacent mainland, 
extending at least as far north as Amoy and to the Island of 
Formosa, and found also in Khasia and Assam. 
*Heptapleurum octophyllum, Benth. in Benth. and Hook. f. Gen. 
Plant. i. 942. (=Paratropia cantoniensis, Hook. and Arn.; Benth. 
Fl. Hongk. 136.) 
*Cornus kousa, Buerg. herb., teste Miq. Ann. Mus. Bot. Lugd.-Bat. ii. 
159. (zBenthamia japoniea, Sieb. and Zucc.; Benth. Fl. Hongk. 138.) 
The reduction of Benthamia to Cornus, effected by Dr. Hooker 
in the ‘Genera,’ had been already indicated as imperative by Prof. 
Asa Gray (Mem. Amer. Acad. n. s. vi. 392). For the sake of 
conformity to the nomenclature of Endlicher, the section to 
which the Hongkong and Japanese species and its Himalayan 
relative belong might be named Cephalocrania. I may here 
remark that it is by inadvertence that C. officinalis, Sieb. and 
Zuce., figured at plate 50 of the ‘ Flora Japonica,’ is referred in 
the ‘Genera’ to Zünycrania; as that section was limited by 
Endlicher, it fell into it, and was rightly so cited by him (Gen. 
Plant. Suppl. i. 1415); but it belongs to Dr. Hooker’s fourth 
section, for which I would propose the name Chrysocrania. 
*Oldenlandia. 
This genus, including the sections Anotis, Houstonia, Sclero- 
mitrion, and Kohautia (the two latter of which he had before 
thought of generic rank), was admitted by Mr. Bentham in the 
‘Flora Hongkongensis ;’ but in the ‘Flora Australiensis’ he re- 
combines it with Hedyotis. Prof. Asa Gray, on the other hand 
(Man. Bot. N. Un. St. ed. 5, 211), considers both Oldenlandia 
and Houstonia well-marked genera; and I think the very pe- 
culiar shape and small number of the seeds of the latter may 
justify its retention. To this latter group belong Hedyotis 
Jtheedei, W. & A., H. monosperma, W. $ A., H. Thwaitesiana, 
Hance, H. boerhaavioides, Hance, and other Asiatic species. 
*Ophiorrhiza japonica, Blume; Sieb. and Zucc. Fl. Jap. Fam. Nat. ii. 
177. (=0. Eyrei, Champ. ; Benth. Fl. Hongk. 147.) 
*Webera corymbosa, Willd. ; Roxb. Fl. Ind. i. 696. ( = Stylocoryne 
Webera, 4. Rich. ; Benth. Fl. Hongk. 156.) 
Dr. Hooker informs me (in litt.) that there are two plants under 
this name in the * Flora Hongkongensis,’ with very different seeds. 
*Webera mollissima, Benth, msc. (=Stylocoryne mollissima, Walp. ; 
Benth. Fl. Hongk, 156.)
