CAPRIFOLIACEAE. — LONICERA 139 



This species forms with L. Webbiana Wallich, L. heterophylla Decaisne, L. 

 heteroloba Batalin, L. tatsienensis Franchet, and L. perulata Rehder a group of very 

 closely related species. The first differs chiefly in the glandular pubescence, pale 

 flowers and broader not acuminate partly reflexed bud-scales; L. heterophylla in 

 the quite glabrous foliage; L. heteroloba and L. tatsienensis differ in the smaller re- 

 flexed bud-scales, in the smaller leaves being pilose on the whole under surface and 

 usually rounded at the base and in the shorter bracts; L. perulata is easily distin- 

 guished by its numerous obtuse bud-scales. From all these species L. mupinensis 

 differs in its upright lanceolate acuminate bud-scales; in the shape of the leaves and 

 in the amount of pubescence it seems rather variable.

Western Szech'uan: Pan-lan-shan, west of Kuan Hsien, alt. 

 2100-3000 m., June 1908 (No. 1870), August 1910 (No. 4037), Octo- 

 ber 1910 (No. 4319). 



One of Wilson's specimens under No. 1870 has part of the leaves deeply and 

 irregularly lobed, but agrees otherwise with the type; another specimen under the 

 same number and No. 4319 differ in their nearly glabrous and broader leaves.

Western Hupeh: Hsing-shan Hsien, cHffs, rare, alt. 1800 m.. May 

 1907 (No. 1871). 



No. 1871 differs from the type in the leaves being loosely pubescent beneath 

 and sometimes rounded at the base, in the shorter cupule and in the style being 

 glabrous near the apex.

Lonicera modesta, var. lushanensis Rehder, n. var. 

 A typo recedit foliis ovalibus v. oblongis, glabris v. fere glabris. 

 Kiangsi: Kuhng, Lushan Mountains, side of streams, common, 

 alt. 1200 m. (Nos. 1657, type, 1655, 1656). 



This variety seems rather variable in pubescence and shape of the leaves; No. 

 1657 has the young branchlets villous and the midrib on both surfaces of the leaves 

 and also the peduncles and bractlets pubescent; the leaves are oval to elliptic. 

 No. 1655 is nearly glabrous except a few hairs on the petioles, the peduncles and 

 on the branchlets just below the nodes; the leaves are elliptic to ovate-lanceolate 

 and often acute. No. 1656 has the pubescence of the preceding specimen, but the 

 leaves are narrowly elliptic or oblong and obtuse or acutish.
