42 WILSON EXPEDITION TO CHINA 
from any of the following four varieties. No. 4339 has the petioles and the leaves 
slightly pubescent beneath, and may be considered a transition to the following 
variety. 
Schizophragma integrifolium, var. molle Rehder, n. var. 
Differt a typo foliis subtus dense et molliter pubescentibus petiolis 
1.5-6 cm. longis, villosis eyma laxe pubescente. Sepala florum ste- 
rilium ovata, basi rotundata, acutiuscula, 5-8 em. longa, 3-5 cm. lata. 
Western Szech'uan: Wa-shan, cliffs, alt. 1600-1800 m., July 
1908 (No. 1251, in part, flowering specimen only); Mupin, cliffs, alt. 
1800 m., July 1908 (No. 1251, in part, flowering specimen). 
Strikingly different from the type in the dense and soft tomentum of the under 
side of the leaves, which otherwise in texture, size and shape resemble closely those 
of the typical form. 
Schizophragma integrifolium, var. denticulatum Rehder, n. var. 
Differt a typo foliis membranaceis vel fere chartaceis, ovato-oblongis 
vel ovatis, basi rotundatis, acuminatis, minuto-dentatis vel denticu- 
latis basi excepta, 10-15 cm. longis et 5.5-9 em. latis, concoloribus, sub- 
tus ad venas laxe et ad venulas sparse pilosis, petiolis glabrescentibus, 
3-7 cm. longis. Sepala florum sterilium ovato-oblonga basi late 
cuneata, 4-6 (-8) em. longa et 2-3 (—4) em. lata. 
Western Hupeh: Chang-lo Hsien, rocky places, alt. 1200 m., 
June 1907 (No. 2563); Hsing-shan Hsien, cliffs, rocky places, alt. 1200- 
1800 m., November, July and August 1907 (Nos. 572, 2566, 2567); 
Changyang Hsien, rocks, sunny places, alt. 900-1200 m., April and

Differs from the type in its thinner, dentate or denticulate leaves, slightly pu- 
bescent on the veins beneath or sometimes glabrous. In the No. 2563 which I 
consider the type of this variety and also in No. 4462 the leaves are sinuately 
dentate, while in all the others they are merely denticulate. 
Schizophragma integrifolium, var. glaucescens Rehder, n. var. 
A typo recedit folis chartaceis, ovatis v. oblongo-ovatis, basi 
rotundatis v. late cuneatis, integris, 8-12 cm. longis et 3.5-7 cm. 
latis, supra laete viridibus, subtus glaucescentibus glabris sed in 
axillis barbatis; sepalis florum sterilium oblongis acutiusculis, basi 
cuneatis, 3.5-5 cm. longis et 1-2 cm. latis.
