 cea, ovata v. minora ovato-rotmida,basi rotundata v. subcordata, apice 

 plerumque obtusa,iiiterdum subrotunda, raro subacuta,nervisutrinque 

 8-10, supra viridia, an opaca?, subtus satis pallida, nervis in sicco flaves- 

 centibus, pruinosa v. indistincte papillosa, minora 1.6-2.5 cm. longa 

 et 1.3-2.2 cm. lata, majora 3-5 cm. longa et 2-3 cm. lata; petioli 0.9- 

 2 cm. longi, glabri. Inflorescentia terminalis, anguste paniculata v. 

 racemoso-paniculata, glabra, 8-12 cm. longa; Acres ad 3-8 fascicu- 

 lati, flavescentes, fragrantes, circiter 2-2.5 cm. longi; alabastra 

 globosa obtusa, pedicellis sublongiora; sepala oblongo-ovata, apice 

 obtusa; petala sepalis breviora, obovata, basi breviter unguiculata,

Western Hupeh: Hsing-shan Hsien, thickets, alt. 300-1200 m., 

 June 1907 (No. 3386, type). Western Szech'uan: west and near 

 Wen-ch'uan Hsien, woodlands, alt. 1600-2000 m., June and July 

 1908 (No. 3380); without locality, alt. 3150 m., June 1904 (Veitch 

 Exped. No. 3337). Eastern Kansu: 1885, G. N, Potanin (a rather 

 meagre fruiting specimen in Herb. Bot. Card. St. Petersbourg, deter- 

 mined as B. lineata). 



I am not quite convinced that Potanin's specimen really belongs to B. sinica. 

 According to the shape of the non-papillose leaves, their long petioles and tne 

 rather obtuse flower-buds Wilson's No. 700^ from western Ilupch, J«y ^^^ 

 (specimen in Herb. Hofmuseum, Vienna) might be referred to this species, although 

 the inflorescence much resembles that of B. yunnanensis Schneider.

Frutex diffusus v. scandens 2.5-5 m. altus; ramuli homotini glabri, 

 rotundi, viridi-olivacei, vetustiores flavido-brunnescentes; gemmae 

 stipulaeque ut videtur normales. Folia papyracea, ovato-elliptica 

 V. oblongo-elliptica v. ovata, basi obtusa v. rotunda, apice distmcte 

 acuta, mucronulata, supra obscure viridia, glabra, subtus pallida 

 viridia V. pallida, satis distincte papillosa, nervis utrinsecus plerumque 

 10-13, minora circiter 3^ cm. longa et 1.6-2.5 cm. lata, majora 3- 

 6.5 cm. longa et 1.5-2.7 cm. lata; petioli 1-1.5 cm. longi, glabn. in- 

 florescentia racemoso-paniculata, densiflora, termmalis, in apice 



' The specimen of this number from Patung Hsien in the Herbarium of the 

 Arnold Arboretum certainly belongs to B. sinica. A. it. ana r.. xi. .
