 ting, alt. 2700 m., June 1908 (No. 1883). 



Lonicera tubuliflora seems most nearly related to L. syringantha Maximowicz, 

 which is easily distinguished by its much wider lilac corolla with the tube only 

 three times as long as the limb and not constricted at the mouth, by the 3-celled 

 ovaries, the longer lanceolate calyx-teeth, the higher cupula and the larger often 

 acute leaves.

 (1891). 



Western Szech'uan: uplands around Tachien-lu, alt. 2500 m., 

 July 28, 1908 (No. 827, in part); around Sungpan, abundant, alt. 

 2400-3000 m., August 1910 (No. 827, in part).

 bourg, XXIV. 49; in Mel Biol X. 77 (1877). 



Western Szech'uan: upland thickets, Ta p'ao shan, northeast of 

 Tachien-lu, alt. 3600 m., July 6, 1908 (No. 1872); Pan-lan-shan, west 

 of Kuan-Hsien, alt. 3600 m., June 24, 1908 (No. 1873). 



Wilson's specimens differ slightly from the type in their shorter corolla tube, 4-5 

 mm. long, and in their narrower and smaller leaves broadly cuneate at the base and 

 usually in threes. One of the branches shows the young leaves beneath and the 

 flower buds furnished with a very slight floccose pubescence which soon disap- 

 pears.
