108 WILSON EXPEDITION TO CHINA 
eality (Veitch Exped. No. 1382); no locality, A. Henry (No. 6543). 
Eastern Szech’uan: South Wushan, A. Henry (No. 5691). 
From the Szech’uan form this variety differs chiefly in its glabrescent leaves, 
the slender and loose inflorescence with part of the flowers on slender pedicels, 
the saucer-shaped calyx with very broad, often obsolete, teeth, the yellow anthers 
and the narrower fruits. Some specimens, however, as Nos. 1814 and 1824, ap- 
proach in their narrower and more pubescent leaves the Szech’uan form, but they 
have yellow anthers, while some Szech’uan plants have a saucer-shaped calyx like 
var. gracilipes.!

(1888). 
Western Hupeh: ravines around Ichang, alt. 30-300 m., March

Wilson's flowering specimen bears on its label the note “flowers white function- 
ally dioecious " and consists of two branches apparently from different plants and 
Showing two kinds of flowers. One of the branches bears a terminal many-flowered 
panicle with the peduncle 6.5 cm. long; the corolla does not seem to be fully de- 
veloped, the lobes are upright and slightly incurved, not spreading, the rudimentary 
stamens are about 1 mm. long with deformed dark colored and empty anthers, and 
the short thick style bears a large capitate three-lobed stigma. The other branch 
bears two small panicles, 1.5 and 2.5 cm. long, in the axils of the leaves of the pre- 
ceding year; the corolla is rotate, about 6 mm. in diameter, with spreading lobes; 
the stamens are 4 mm. long and exceed somewhat the corolla-lobes, with yellow 
oval pollen-bearing anthers; the style is reduced to its conical base with three minute 
blunt points at the apex; the ovary is smaller and apparently sterile. As I have 
seen no other flowering specimen of the species I do not know whether dioecious 
flowers are the rule or whether this is only an abnormal case. No other speciesin 
the genus Viburnum is known to have diclinous or incompletely diclinous flowers.

Western Szech'uan: Wa-ssu country, Wén-chuan Hsien, thickets, 
alt. 1500-1800 m., July and October 1908 (No. 1031); Mupin, thickets, 
alt. 1200-2250 m., May and August 1908 (No. 805*). 
! In connection with these varieties another very distinct variety of V. eru- 
bescens from Upper Burma may be described here: 
Viburnum erubescens, var. burmanicum Rehder, n. var. 
Folia chartacea, glabra, oblonga, basi rotundata, apice subito in acumen longum 
falcatum producta, remote denticulata, 10-12 em. longa et 4.5-5.5 cm. lata, supra 
obscure viridia, subtus pallidiora, utrinsecus 6-costata costis curvatis anasto- 
mosantibus trabiculis parallelis conspicuis conjunctis. Panicula glabra, longe 
pedunculata, late pyramidalis, 6-8 em. diam. et 4-6 cm. longa; corolla 
dibuliformis limbo patulo, antheris flavis semiexsertis. 3 
Upper Burma: Kachin Hills, 1898. Shaik Mokim (Ex. Herb. Hort. Calcutt. in 
Herb. Arnold Arboretum). 
This very distinct form is easily recognized by its chartaceous perfectly oblong 
= quite glabrous remotely denticulate leaves and by the very broad and short 
orescence.
