136 WILSON EXPEDITION TO CHINA 
Lonicera mucronata Rehder in Rep. Missouri Bot. Gard. XIV. 83, t. 
2, fig. 8-9 (1903); in Sargent, Trees and Shrubs, II. 47, t. 122 (1907). 
Western Hupeh: Hsing-shan Hsien, cliffs, alt. 300-€00 m., March 
26 and May 24, 1907 (No. 801). 
Subsect. BRACTEATAE Hook. f. & Thoms. 
Lonicera mitis Rehder in Sargent, Trees and Shrubs, II. 50 (1907); 
in Fedde, Rep. Sp. Nov. VI. 271 (1909). 
Western Szech’uan: southeast of Tachien-lu, uplands, alt. 3600- 
3900 m. (No. 4139). 
As the mature leaves and fruits of this species have not been described, their 
description may be given here: Leaves oblong or obovate-oblong, acutish or ob- 
tuse and mucronulate, broadly cuneate at the base, 2-3 cm. long and 8-15 mm. 
broad, minutely velvety on both sides, margin revolute, dark green above, netted 
with paler veins, paler green beneath and reticulate; petioles 1-2 em. long, puberu- 
lous. Fruits on very short peduncles 1-3 mm. long, ovoid, longer than the bracts 
deciduous at maturity, bluish black, usually with 3-8 seeds; seeds irregularly 
triangular-oblong, lustrous, dark brown, 4.5 mm. long. 
This and L. cyanocarpa Franchet are so far the only species known of the Brac- 
teatae which have blue or bluish black fruits. Lonicera cyanocarpa, of which the 
flowers are unknown, is apparently closely related, but easily distinguished by the 
narrower and somewhat larger coriaceous leaves, setulose-ciliate on the margin and 
by the ovate-lanceolate acuminate and ciliate bracts. When in fruit L. mitis looks 
in general appearance so much like L. coerulea that it might be taken for that 
species if it were not for the distinct berries. 
Lonicera setifera Franchet, var. trullifera Rehder, n. var. 
Folia quam in typo majora, 6-12 cm. longa petiolis basi valde dila- 
tatis oppositis connatis et cupulam oblongam subtus manifeste triner- 
vem interdum plus quam 1 em. latam et 2.5 cm. longam formantibus. 
Western Szech’uan: near summit of Nin-tou-shan, west of Kuan 
Hsien, alt. 2700 m., June 20, 1908 (No. 902°). 
The leaves of this variety have the same coarse dentation, a very unusual feat- 
ure in the genus, as those of the type from Yunnan, but are nearly twice as large. 
As long as the type and this variety are known from a single collection each, it can- 
not be decided whether the peculiar dilated petioles are an essential feature of the 
variety or may also occur on vigorous branches of the type.

neis v. griseo-brunneis cortice laevi. Gemmae perulis exterioribus 2
