382 WILSON EXPEDITION TO CHINA 



ENUMERATIO SPECIERUM ASIATICARUM. 



Sectio Longibracteatae Fedde, in Bot. Jahrb. XXXI. 78 (Monog. Mahonia) (1901). 

 To this section belong all species known from Asia and also one from the Pacific 

 North America {M. nervosa [Pursh] Nuttall). 



1. Mahonia japonica De CandoUe, Syst. II. 22 (1821). 



Ilex Japonica Thunberg, Fl. Jap. 77 (1784). 



Berheris japonica R. Brown in Tuckey, Congo Exped. App.. 22 (1816). 



Szech'uan: Hants'ao-kan, Nanch'uan, anno 1891, A. von Rosthorn (No. 174 

 ex Fedde); Huang-hua-shan, Nanch'uan, A. von Rosthorn (No. 1213 ex Fedde). 



I have not seen a specimen of a wild plant of this species, which seems to be 

 very nearly related to M. nepalensis, from which it differs in its opaque, not shin- 

 ing leaves rather paler below. Fedde says, that the bracts are acuminate and as 

 long as the pedicels, but in my specimens of var. Bealei (Fortune) Fedde the bracts 

 are only half as long as the pedicels and are not acuminate. Koehne {Deutsche 

 Dendr. 165) states, that the ovaries of M . japonica contain about four ovules, while 

 in M. nepalensis there are about seven. I could find only three in var. Bealei and 

 also three, or rarely four, in many specimens of wild plants of M. nepalensis. 



2. Mahonia flavida Schneider, n. sp. 



Frutex ad 2 m. altus. Folia 7-juga, ad 50 cm. longa, ima basi petioH stipulis 2 

 filiformibus spinescentibus instructa, jugo infimo multo minore basi petioli valde 

 approximato; foliola circiter 5 cm. inter se distantia, coriacea, utrinque leviter 

 nitentia, subtus paullo pallidiora, nervis primariis elevatis laxe reticulatis, late- 

 ralia (terminalia nondum vidi), ovato-lanceolata, obliqua, basi parte exteriore 

 rotunda, apice sensim acuminata, margine fere a basi breviter spinoso-dentata 

 dentibus utrinque 4-8, superiora ad 13.5:3.5-4.2 cm. magna, inferiora breviora, 

 ovata, infima quasi stipulaeformia, ad 3.5 cm. longa. Racemi ad 19 cm. longi, 

 satis densiflori, basi bracteis acuminato-triangularibus ad 2.5 cm. longis instructi; 

 flores flavi, circiter 6-7 mm. diam.; bracteae lanceolatae, acuminatae, pedicelhs ad 

 5 mm. longis fere longiores; sepala 3 externa minima, late ovato-cordata, 3 media 

 late oblonga, 3 interna obovato-oblonga, mediis longiora; petala obovata, sepalis 

 internis paullo v. vix minora basi brevissime contracta, glandulifera; stamina 

 petalis paullo breviora, filamenta antheris paullo longiora, apice apiculata; ovaria 

 distincte stylosa, ovulis 3 sessilibus instructa. Fructus ignoti. 



Yunnan: Mengtze, alt. 2000 m., woods, A. Henry (No. 10180). 



This species seems most nearly related to M. japonica De CandoUe and M. 

 nepalensis De CandoUe, but differs from both these species in the shape of the 

 leaflets, which are not as shining as those of M. nepalensis and not dull like those of 

 M. japonica. Possibly it might be considered a variety of M. nepalensis, and there 

 is a specimen from the Khasia Hills collected by Ward (in Herb. Hof-Museum, 

 Vienna), which only differs from this species in its shorter leaflets and in the shorter 

 bracts of the pedicels; the filaments also are not dentate. But I believe that all 

 the Chinese forms, referred to M. nepalensis by Hemsley and other authors, repre- 

 sent difi'erent species. 



3. Mahonia Zemanii Schneider. See p. 378. 



4. Mahonia nepalensis De CandoUe, Syst. II. 21 (1821). 

 Berberis nepalensis Sprengel, Syst. II. 120 (1825).
