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 cm. 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-ciUate on the margin and 

 by the ovate-lanceolate acuminate and ciliate bracts. When in fruit L. mitis looks 

 in general appearance so much hke L. coerulea that it might be taken for that 

 species if it were not for the distinct berries. 



Lonicera setifera Franchet, var. truUifera 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 cm. 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. 



Lonicera subdentata Rehder, n. sp. 



Frutex erectus 1-3 m. altus ramuhs glabris, annotinis pallide brun- 

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

 acutis circa 5 mm. longis. Folia decidua, oblongo-ovata v. elliptico- 

 oblonga, acuminata, basi late cuneata v. rotundata, Integra v. utrin-
