232 JOURNAL OF THE ARNOLD ARBORETUM [vol. v 



of Pterospermum collected by Faber at Hainan without number, which 



ifolium. Upon critical examination I am 



Me 



Canton. As the latter was based on a fruiting specimen only, I give here 



a complete description including that of the flowers based on Faber 's 

 specimen. 



Syzygium gracilentum, comb. nov. 



Eugenia gracilenta Hance in Journ. Bot. xxm. 7 (1885). 

 Hance referred this species to the sect. Syzygium. Since it is better to 

 separate Syzygium from Eugenia as a distinct genus, I propose this new 

 combination. 



Gilibertia acuminatissima, comb. nov. 



Dendropanax acuminatissimum Merrill in Philipp. Jour, of Sci. xin. 152 (1918). 

 Gilibertia Ruiz & Pavon was published in 1794 and Dendropanax Plan- 

 chon in 1S54. Nakai reduced the latter to a section of Gilibertia (see p. 22 

 of this vol.); in following him I propose this new combination. 



Maesa Henryi, sp. nov. 



Maesa castancifolia Mez in Engler Pflanzenr. IV.-236 (Myrsinac.) 44 (1902), 



pro parte.

 longa et 3.5-5 cm. lata, acuminata vel acuta, basi subrotundata vel cu- 

 neata, remote serrata vel subintegra, supra glabra, subtus ad venas puber- 

 ula; petioli ad 12 mm. longa. Inflorescentia diffuse paniculata, multiflora, 

 glabra; pedicelli graciles, patentes: flores albi, in sicco pallide cremei; 

 calycis lobi late triangulari-ovati, obtusi, patentes, tertiam partem corollae 

 aequantes; corolla rotato-campanulata, lobis ovatis patentibus. Fructus 

 succulentus, turbinatus vel subglol>osus, 6 mm. longus, calycis lobis per- 

 sistentibus patentibus coronatus; semina angulata, nigra. 



Affinis M. castaneifoliae Mez, sed differt inflorescentia laxiore, corolla 



rotato-campanulata, fructu magis majore succulenta et seminibus nigris. 



Yunnan: Szemao, A. Henry, nos. 11625 (type) and 11625 A; G. Forrest, 

 no. 16151. 



Szechuan: Yangtze banks, E. II. Wilson, Veitch Exp. no. 4059, April, 

 1904; Bank of Yangtze, Chung chow, alt. 150 m., E. H. Wilson, no. 3257, 

 April, 1908. 



Tylophora Dielsii, comb. nov. 



Hoyopsis Dielsii L6veill6 in Fedde, Rep. Spec. Nov. xin. 262 (1914). 

 Tylophora Hoyopsis L6veill6, Fl. Kouy-Tcli<5ou, 44 (*1914). 



The combination made by Leveille under Hoyopsis was not in ac- 

 cordance with the rules of nomenclature as he disregarded his former 

 specific name given under his genus Hoyopsis, therefore a new combination 

 is necessary.
