flora, ad 4 cm. longa, rhachide ruf o-tomentella ; pedicelli filiformes, ad 

 apicem leviter incrassati, 3.5 mm. longi; flores luteo-virides, fragrantes; 

 stamina 2.5 cm. longa, filamentis gracilibus, antheris globis pallide luteis; 

 stigma brunneum. Fructus ignotus. 



Species foliis subsessilibus ab omnibus aliis speciebus generis distincis- 

 sima. 



Chekiang: Taichow, on exposed grassy foothill, 30 ft. altitude, Ren- 

 Chang Ching, no. 1297 (type), April 30, 1924; Changhua, on rocky slopes, 

 900 ft. altitude, F. N. Meyer, no. 1548, July 12, 1915. 



Meyer's is a sterile specimen which has leaves up to 11 cm. long and 6.5 

 cm. broad, evidently coming from a vigorous young shoot. 



Vitis chunganensis, sp. no v. 



Frutex scandens, ad 1.5 cm. altus; rami graciles, subflexuosi, glabri; 

 cirrhi satis robusti. Folia cordato-ovata vel cordato-subdeltoidea ad 14 

 cm. longa et 9 cm. lata, breviter acuminata, sinu basali lato et profundo, 

 lateribus rotundatis, ad basin serrata dentibus valde remotis calloso- 

 mucronulatis, utrinque glabra, supra lucide viridia, subtus albido-glauca, 

 magis reticulata supra quam infra; petioli ad 6 cm. longi, rubro-brunnei. 

 Inflorescentia paniculata, laxa, ad 13 cm. longa, sine cirrhis, rhachide 

 glabra; pedicelli satis robusti; baccae immaturae globosae, circiter 8 mm. 

 diam. 



Affinis V. fiexuosae Thunb. sed foliis majoribus subtus glaucis distincta. 



Fokien: Chung-An Sien, H. H. Hu, no. 1348 (type), September 27, 1921; 

 without precise locality, S. T. Dunn, no. 2504, April to June, 1905. Dunn's 

 specimen is with very young fruits. 



'Metaplexis sinensis, comb. nov. 



Holostemma sinense Hemsley in Jour. Linn. Soc. xxvi. 103 (1889). 

 Metaplexis Hemsley ana Oliver in Hooker's Icon. PL xx. t. 1970 (1891). 



Apparently C. Schneider overlooked Oliver's name when he gave a 

 supplementary description of this species in Plantae Wilsonianae, in. 344 

 (1916), as he did not cite Oliver's name as a synonym. He also said: "I 

 doubt if our plant belongs to Holostemma at all. . . . Since Oliver made 

 it clear that this species is closely related to Metaplexis Stauntoni, the 

 position of this species seems settled. Since Oliver did not make a correct 

 combination, I take this chance to propose it. 



Tabernaemontana pallida, comb. nov. 



Ervatamia pallida Pierre in Spire, Caoutch. Indo-Chine, 141 (1906). 



Otto Stapf in Thiselton-Dyer, Flora of Tropical Africa, 126 (1902) 

 raised the section Ervatamia of Tabernaemontana to generic rank, but 

 E. D. Merrill in his various writing did not take up this new genus. I also 

 think the difference is not pronounced, and it is better to reduce Ervatamia 

 to a section again. Hence the new combination for this species.
