1-1.75 m., flowers white) ; near Yachou Fu, alt. 600-800 m., September 

 1908 (No. 3733; sub-shrub 1-2 m., flowers pale pink or white); Tung 

 River valley, near Wa-shan, thickets, September 1908 (No. 3533; 

 sub-shrub 1.25 m., flowers white); Wa-shan, October 1903 (Veitch 

 Exped. No. 4307; sub-shrub 1.75 m., flowers white); Wen-ch'uan, 

 August 1891, A. von Rosthorn (No. 3004). Western Hupeh: with- 

 out precise locality, A. Henry (No. 6755). Yunnan: Mengtsze, 

 grass mountains, alt. 1500 m., A. Henry (No. 11305; shrub 0-6-1 

 m., yellowish flowers); "in dumetis collium orient, prope pagum 

 Ngu-leh-keh in reg. Lichiang," alt. 3200 m., August 14, 1914. C. 

 Schneider (No. 2255; flowers white) ; Tali Range, G. Forrest (No. 4759). 



This species seems very variable in the pubescence of the leaves; in Wilson's 

 No. 3532 and in Rosthorn's No. 3004 the under surface of the leaves is densely vil- 

 lose, while in Wilson's No. 3733 and in Henry's No. 6755 the pubescence is shorter 

 and much less dense; Wilson's Nos. 3533 and 4307 have the under side covered by 

 a close white tomentum and represent apparently a distinct variety. 



Elsholtzia fruticosa, var. tomentella Rehder, n. var. 



A typo recedit foliis subtus tomento minuto albido v. canescente 

 dense obtectis et reticulatis margine minus argute serratis plerum- 

 que in triente v. dimidio inferiore Integra et supra minute et remote 

 serrulatis v. grossius serratis. 



Western Szech'uan: Wa-shan, October 1903 (Veitch Exped. 

 No. 4307, type; sub-shrub 1.6 m., flowers white); near Wa-shan, 

 Tung River valley, thickets, alt. 900-1200 m., September 1908 (No. 

 3533^; sub-shrub 1.3 m., flowers white). 



In the close whitish tomentum of the under side of the leaves this variety differs 

 markedly from the type, but as there is apparently no difference in the flowers, it 

 does not seem advisable to treat it as a distinct species. 



Elsholtzia flava Bentham, Lahiat. 161 (1832); in De Candolle, 

 Prodr. XII. 160 (1848). — Hooker f., FL Brit. Ind. IV. 642 (1885). — 

 Diels in Not. Bot. Gard. Edinburgh, VII. 40, 260 (PI. Chin. Forrest.) 

 (1912). — Dunn in Not. Bot. Gard. Edinburgh, VI. 149 (1915). 



Aphanochilus flavus Bentham in WalHch, Cat. 1553 (nomen nudum) (1S2S) ; 

 in Wallich, PI. As. Bar. I. 28, t. 34 (1830). 



Western Szech'uan: Hungya Hsien, foot of Wa-wu-shan, alt. 

 1200 m., September 13, 1908 (No. 3535, sub-shrub 1 m., flowers 

 bronzy-red). Yunnan: "in dumetis ad lat. orient, mont. niveorum 

 prope Lichiang," alt. 3200 m., October 1914, C. Schneider (No. 3907). 



Wilson's specimen differs in the broadly cuneate base of the leaves from the 

 Himalayan and Yunnan specimens before me, which have the leaves subcordate 

 at the base.
