RHAMNACEAE. — BERCHEMIA 215 



Berchemia sinica Schneider, n. sp. - ^ ruic^v.^w^^ 



Frutex scandens, 4-6-metralis; ramuli rotundi, glabri, flavescentes 

 V. leviter brunnescentes ; gemmae stipulaeque normales. Folia papyra- 

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

 plerumque obtusa, interdum 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; floras 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, 

 staminibus aequilonga; ovaria discum paullo superantia. Fructus 

 cylindricus, niger, 5-6 mm. longus, 2.5 mm. crassus. 



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. Gard. 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 the 

 rather obtuse flower-buds Wilson's No. 700 1 from western Hupeh, July 1900 

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

 the inflorescence much resembles that of B. yunnanensis Schneider. 



Berchemia pycnantha Schneider, n. sp. ^ IS . ruuL^..^^^,^^ 



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

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

 stipulaeque ut videtur normales. Folia papyracea, ovato-elliptica 

 V. oblongo-elhptica v. ovata, basi obtusa v. rotunda, apice distincte 

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

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

 10-13, minora circiter 3-4 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, glabri. In- 

 florescentia racemoso-paniculata, densiflora, terminalis, in apice 



^ The specimen of this number from Patung Hsien in the Ilcrbarium of the 

 Arnold Arboretum certainly belongs to B. sinica. A. R. and E. H. W.
