384 WILSON EXPEDITION TO CHINA 



8. Mahonia Duclouxiana Gagnepain in Bull. Soc. Bot. France, LV. 87 (1908). 

 Yunnan : " pres des routes a Lou-kiou-sen, 10 fev. 1905," Dudoux (No. 3055); 



" route de Yunnan-sen a Kiu-tsin-fou, non loin de Ma-long, 20 mars 1904." Du- 

 doux (No. 2323); " bois des montagnes a Guon-kay [Ho-kin], 24 mars 1885," 

 Delavay (No. 2353, " fruits mUrs bleus, arbuste peu rameux de 2 m."). 



I have not seen a specimen of this species, but according to the description I 

 think it may be different from all the species known to me. 



9. Mahonia decipiens Schneider. See p. 379. 



10. Mahonia annamica Gagnepain in Lecomte, Fl. Gen. Indo-Chine, I. 157, fig. 

 16 (7-17) (1907). 



Annam: " Haut-Donnai, plateau de Lang-bian," Jacquet (ex Gagnepain). 



I know this species only from the description of the author. It may be most 

 nearly related to M. nepalensis De Candolle and M. japonica De CandoUe, from 

 which it differs by the characters given in the key on p. 381, The stamens are 

 apiculate and the filaments twice longer than the anthers. 



11. Mahonia Bodinieri Gagnepain in Bull. Soc. Bot. France, LV. 85 (1908). 

 Kwei-chou: " environs de Gan-pin, dans les bois et rocailles, et mont du Col- 

 lege k Kouy-yang, 19 juillet 1898," E. Bodinier (No. 2465). 



This seems to be a distinct species, but the fruits are not known and I am not 

 quite sure whether the style is entirely wanting. 



12. Mahonia nitens Schneider. See p. 379. 



13. Mahonia Sheridaniana Schneider, n. sp. 



Frutex. Folia 4-5-juga, ad 26 cm. longa, jugo infimo multo minore basi petioli 

 magnopere approximato, ima basi petioli stipulis 2 filiformibus minimis instructa; 

 foliola valde coriacea, supra ut videtur satis claro-viridia, vix nitentia, subtus dis- 

 tincte bicoloria, in sicco fere albescentia, nervis primariis paullo visibilibus, late- 

 ralia a basi petioli versus apicem ejus accrescentia, inferiora late ovata, circiter 

 3:2.3 cm. magna, superiora ad 8.5:2.7 cm. magna, ovato-lanceolata, satis obhqua, 

 basi externa rotunda, apice breviter acuminata, margine late sinuato-spinoso-den- 

 tata, spinis utrinque 2-5; terminaha elliptico-lanceolata, ad 11:3.5 cm. magna, 

 inferiore parte plerumque Integra. Racemi (an satis evoluti?) ad 7 cm. longi, 

 densiflori, earum bracteae late-triangulares, breviter acutae, vix 1 cm. longae; 

 flores lutei (?), initio extus rubescentes (?), circiter 5(-6) mm. diam.; pedicelli 2-4 

 cm. longi, bracteis ovato-lanceolatis, subacutis, aequilongis v. paullo brevioribus 

 suffulti; sepala 3 externa minima, ovata, 3 media majora late ovata, 3 interna 

 maxima, late ovata; petala obovata, sepahs internis paullo breviora, apice incisa, 

 basi breviter unguiculata, glandulifera; stamina quam petala breviora, normalia, 

 filamentis antheris subaequilongis; ovaria ut videtur estylosa, ovuUs 2 instructa. 

 Fructus ignoti. 



Western Hupeh: April 1900, E. H. Wilson (Veitch Exped. No. 426). 



It is impossible for me to refer Wilson's specimen to any described species. M. 

 Sheridaniana differs from all the species with sessile stigmas in the form and color 

 of its leaflets. And even if the fruits did bear a very short style it would not prove 

 identical with any of the species described. At the request of Mr. Wilson I have 

 named this species for Dr. W. R. Sheridan, formerly in charge of the American 

 Methodist Mission Hospital, Chengtu, in recognition of great service rendered to 

 him during the autumn of 1910.

 Mahonia) (1901).
