et 5 mm diametro, extus dense et minutissime f errugineo-stellato- 

 tomentosis. 



Kwangtung Province, Sum Sun, Nam Hoi, at the base of a hill, Levine 

 1173, September 7, 1917. 



The alliance of this species is manifestly with Pterospermum jackianum 

 Wall., to which I first referred the specimen. It differs from Penang 

 material representing Wallich's species, and from the descriptions in a 

 number of details, notably in its entirely different stipules. 



The only species reported from China proper are the entirely different 

 Pterospermum proteus Burkill and P. heterophyllum Hance; Pterospermum 

 formosanum, Mats., judging from the single sterile specimen I have seen, 

 must be very closely allied to or identical with the Philippine P. niveum 

 Vid. 



DILLENIACEAE 



TETRACERA Linnaeus 



TETRACERA LEVINEI sp. nov. 



Frutex scandens, subglaber; foliis oblongis, rigidis, laevis vel 

 sublaevis, usque ad 13 cm longis, in siccitate pallidis, nitidis, 

 basi acutis, apice acutis, obtusis, vel obscurissime acuminatis, 

 nervis utrinque circiter 15, perspicuis; paniculis axillaribus 

 terminalibusque, usque ad 12 cm longis; fructibus circiter 7 

 mm longis, glabris, 1-spermis, sepalis utrinque glabris. 



A scandent shrub, subglabrous, the inflorescences somewhat 

 appressed-strigose. Branches brownish, somewhat wrinkled, 

 smooth or minutely scabrid. Leaves subcoriaceous, rigid, brit- 

 tle, oblong, pale and shining when dry, smooth or nearly so, 

 11 to 13 cm long, 4 to 5 cm wide, base acute, apex acute, some- 

 what obtuse, or even slightly acuminate, the margins minutely 

 denticulate in the upper one-half; lateral nerves about 15 on 

 each side of the midrib, prominent. Panicles terminal and in 

 the upper axils, up to 12 cm in length. Fruits 1-seeded, ovoid, 

 glabrous, shining, somewhat apiculate, about 7 mm long, the 

 aril orange-yellow. Sepals glabrous on both surfaces. 



Kwangtung Province, White Cloud Mountain, near Canton, Levine ITH, 

 near small streams, October 22, 1917. 



This species is manifestly allied to Tetracera scandens (Linn.) Merr. 

 (T. sarmentosa Vahl), which is common in Kwangtung Province, from 

 which it differs in its smooth or nearly smooth, not scabrid leaves, and 

 more numerous lateral nerves. The synonyms Leontoglossum scahrum 

 Hance, Actaea aspera Lour., Trachytella actaea DC, and Calligonum 

 asperum Lour., based on Kwangtung and Cochinchina specimens, appear 

 to be correctly referred to Tetracera sarmentosa Vahl^T". scandens (Linn.) 

 Merr. The latter species is represented by Hongkong Herbarium HIS, 

 from Hongkong, and Merrill 107 2U and Levine HI 8 from the base of Loh 

 Fau Mountain, Kwangtung Province.
