THEACEAE 



EURYA Thunberg 

 EURYA GROFFIl sp. nov. 



Frutex vel arbor parva; ramis teretibus, glabris, ramulis pi- 

 losis; foliis lanceolatis, chartaceis vel subcoriaceis, usque ad 6 

 cm longis et 1.2 cm latis, nitidis, supra glabris, subtus pilosis, 

 apice tenuiter acuminatis, basi obtusis, plerumque leviter inae- 

 quilateralibus, costa supra impressa, subtus cum venis promi- 

 nulis; fructibus axillaribus, fasciculatis, giobosis vel ovoideis, 

 glabris, stylis connatis; sepalis elliptico-ovatis, exterioribus lev- 

 iter pilosis, coriaceis, 1.5 ad 2 mm longis. 



A shrub or a small tree, the branchlets rather densely pilose. 

 Branches terete, glabrous, dark reddish brown. Leaves numerous, 

 lanceolate, chartaceous to subcoriaceous, greenish olivaceous and 

 shining v/hen dry, 3.5 to 6 cm long, 8 to 12 mm wide, the mar- 

 gins denticulate, the upper surface glabrous, the lower pilose, 

 the midrib above impressed, prominent beneath, the lateral nerves 

 obsolete or subobsolete on the upper surface, distinct and some- 

 what projecting on the lower surface, the apex slenderly acum- 

 inate, the base obtuse and often minutely inequilaterally cordate, 

 sessile or subsessile. Fruits axillary, glabrous, globose or ovoid, 

 3 to 3.5 mm in diameter, smooth, their pedicels 1 to 1.5 mm long; 

 styles united for the lower 1 mm, the arms about 1 mm long. 

 Sepals coriaceous, elliptic-ovate, 1.5 to 2 mm long, rounded, the 

 outer ones somewhat pilose. 



Kwangtung Province, Tiu Kaan Shan, Tseng Uen, Grojf 2378, 

 March, 1918, on mountain sides. 



In vegetative characters and general appearance this species 

 strongly resembles Eurya sivinglei Merr., but differs radically 

 in its entirely glabrous fruits and much shorter styles. From 

 Eurya distichophylla Hemsl. it is readily distinguished by its 

 slenderly acuminate leaves and the veins obsolete or nearly so 

 on the upper surface and projecting on the lower surface. The 

 fruits and staminate flowers of Hemsley's species are as yet 

 unknown.
