570 WILSON EXPEDITION TO CHINA 
The flowers, shoots and under surface of the leaves of this plant are covered 
with a fulvous-gray, rather loose tomentum which readily distinguishes this 
variety from the type.!

Western Szech'uan: Wa-shan, thickets, alt. 1300-2000 m., 
August 1908 (No. 3358; bush 1.5-2.5 m. tall, flowers purple); south- 
east of Tachien-lu, Tung valley, alt. 1300-2000 m., August 1908 (No. 
3356; bush 1-1.5 m. tall, flowers lilac purple); Wa-shan, alt. 2000- 
2600 m., July 1903 (Veitch Exped. No. 4121 and seed No. 1428, 
type). 
A rather rare plant. Duthie describes the calyx as one-third the length of 
the corolla-tube, whereas, as shown in the figure accompanying his description, it 
is half as long as the corolla-tube.

Frutex 2-metralis; ramuli hornotini sparse stellato-pilosi quadrialati alis ad 
1.5 mm. latis. Folia membranacea, lanceolata v. oblongo-lanceolata, acuminata, 
basi cuneata, serrata dentibus late triangularibus v. rotundatis mucronatis, 14- 
28 cm. longa et 4-7 cm. lata, supra laete viridia, glabra, subtus tomento fulvo- 
cinereo tenui obtecta costa media glabrescente excepta, costa nervis venulis supra 
leviter impressis subtus elevatis; petioli fulvo-tomentosi, glabrescentes, circiter 
l cm. longi. Panieulae plures, anguste cylindricae, 10-20 longae et 1.5-2.5 
diam., laxe fulvo-tomentosae e cymis plurifloris inferioribus breviter v. brevissime 
pedunculatis superioribus sessilibus et paucifloris bracteis bracteolisque subulatis 
instructis compositae; flores subsessiles v. brevissime pedicellati; calyx campanu-

corolla lilacina, extus tomentosa, tubo 5 mm. longo intus in parte superiore 
loso; stamina paullo infra faucem inserta, filamentis brevissimis, antheris ovato- 
oblongis basi cordatis apice fere basim limbi attingentibus; ovarium villosum; 
stylus tubo paullo brevior, stigmate clavato. Capsula (juvenilis) cylindrico- 
stk. acuta, sparse villosa, basi calyce et corolla persistente plus minus fissa 
circumdata. 
Western Szech'uan: without precise locality, in a ravine, alt. 1300 m., 
August 1903 (Veitch Exped. No. 4118). 
Buddleia alata differs from all the allied species in its four-winged stems. Itseems 
most nearly related to B. albiflora Hemsley, which is, however, easily 
by its glabrous or glabrescent corolla, by the glabrous ovary, shorter style and by 
the subterete stems.
