ENUMERATIO SPECIERUM. 



1. Rhamnella Wilsonii Schneider. See p. 222. 



2. Rhamnella Martinii Schneider, n. comb. 



Rhamnus Martini LsSveilliS in Fedde, Rep. Sp. Nov. X. 473 (1912). 



Frutex 1-1.5 m. altus; ramuli tenues, hornotini flavo-virides v. fuscescentes 

 (an tantum in sicco?), vetustiores nigrescentes, ex parte lenticellis flavis obtecti, 

 gemmae nondum visae; stipulae basi persistente nigrescente et apice subulate 

 deciduo 3 mm. longo instructae. Folia alterna, decidua, membranacea, oblongo- 

 elliptica, basi rotundata v. obtusa, apice sensim acuminata, acutissima, circum- 

 circa crenato-serrulata, dentibus accumbentibus calloso mucronulatis, 4-11 cm. 

 longa, 1.5-3.9 cm. lata, supra viridia, glabra, nervis vix v. satis incisis, subtus vix 

 pallidiora, tantum ad costam nervosque parce pilosa, nervis utrinque 6-8 promi- 

 nentibus, angulo satis acuto a costa versus marginem decurrentibus ; petioli breves, 

 supra sulcati, pilosi, 3-4 mm. longi. Inflorescentia axillaris, paniculato-cymosa, 

 sessilis v. pedunculo nudo 1-5 mm. longo suffulta, 2-5-flora, glabra; floras minutis- 

 simi, flavo-virides, iis R. franguloidis simillimi sepalis paullo acutioribus petalis 

 basi obovatis apice emarginatis exceptis. Fructus oblongus, ad 8 mm. longus et 

 3-3.5 mm. diam., rubro-nigrescens, pedicellis ad 4 mm. longis. 



Western Hupeh: April 1901 (Veitch Exped. No. 1990). Kweichou: "En- 

 virons de Gan-pin, rochers au dessus de Ta-tong," May 23, 1898, L. Martin (Herb. 

 Bodinier, No. 2299, type). Yunnan : Mengtze, mountains, alt. 2800 m., A. Henry 

 (No. 10929). 



This species seems most closely related to R. franguloides Weberbauer, but 

 differs from it in the more gradually acuminate leaves with more ascending and 

 somewhat closer nerves, in the black persistent bases of the stipules and in the 

 glabrous few-flowered inflorescence. 



Wilson's No. 1990 which consists of flowering and fruiting branches agrees as 

 well with the type as Henry's No. 10929. 



3. Rhamnella Mairei Schneider, sp. nov. 



Frutex omnino glaberrimus; ramuli hornotini olivacei, vetustiores rubro- 

 brunnei, lenticellis sparsis obtecti; stipulae brunneae, apice setaceo deciduo. 

 Folia papyracea, ovata v. elliptica, basi rotunda v. obtusa, apice sensim acuta v. 

 breviter acuminata, supra viridia, nervis vix impressis utrinsecus 5-7, sub angulo 

 satis acuto divergentibus subtus prominentibus, margine satis angustae breviter 

 serrulata, 3.8-8 cm. longa, 1.7-3.5 cm. lata; petioli supra sulcati, 4-8 mm. longi. 

 Inflorescentia 5-15-flora, brevissime pedunculata, fasciculato-cymosa; flores 

 ut in R. Martinii, flavi. Fructus nondum visus. 



Yunnan: " rochers de Ma-hong, juin 1910," alt. 3000 m., E. E. Maire. 



This species is certainly closely related to R. Martinii Schneider, but can be easily 

 distinguished by the characters indicated in the key.
