d05 WILSON EXPEDITION TO CHINA 



A. Henry (No. 1747); South Cape, A. Henry (Nos. 214, 921); Ban 

 kinsing, A. Henry (No. 553). Assam: Kashia Mts., alt. 1500 m., 

 J. D. Hooker & T. Thomson. Also in Japan {Blume, Oldham, Maximo- 

 wicz, Faurie, Watanahe), Liu-kiu Islands (C Wright), Philippine Islands 

 (Elmer), Java (Horsfield). 



This is a very widely distributed species ranging from the Malayan Archipelago 

 to central Japan and western China and has also been found in eastern Africa. It 

 is characterized by the slender pedicelled flowers, the presence of conspicuous 

 abortive flowers and the very wide and loose inflorescence with the longer rays sub- 

 thyrsoid; like the two preceding species it has red fruits and shows the tendency 

 to have the upper leaflets more or less adnate to the rhachis and sometimes de- 

 current. The Chinese form is usually quite glabrous and certainly has red fruits, 

 as the specimens with rijie fruits show and as it is stated by Hance; the form of the 

 Philippine Islands and of Java has usually a puberulous inflorescence and the leaves 

 generally more or less pubescent on the veins; its fruit is described by Miquel and 

 Hasskarl as greenish, by Junghuhn as yellow. In all other characters, however, 

 the two forms agree perifectly and it does not seem possible to separate them spe- 

 cifically. 



The two following species, which are not represented in the Wilson collection, 

 occur in the Himalayas, and one of them also in China.

Western Szech'uan: near Tachien-lu, alt. 3000-4000 m., A. E. Pratt (No. 

 122). Yunnan: Mengtze, north mts. forests, alt. 2500 m., A. Hcnnj (No. 10772). 

 Tibet: Chumbi, June 27, 1878, Dungboo (Herb. Hort. Bot. Calcutt.). Sikkim: 

 alt. 2000-3500 m., J. D. Hooker. 



This species seems most closely related to S. Wightiana Wallich, from which it 

 differs chiefly in the pubescent inflorescence with the rays subtended by leaves or 

 bracts. From S. javanica it is easily distinguished by the absence of the aborted 

 flowers and the smaller and denser pubescent inflorescence. Sambucus adnata has 

 also been reported from eastern Africa, but its occurrence there is not at all prob- 

 able; very likely specimens of S. javanica with partly adnate leaflets have been 

 erroneously determined as S. adnata.

A specie affini S. javanica Reinwardt praecipue recedit floribus sessilibus v. 

 breviter pedicellatis, floribus sterilibus minoribus, inflorescentia pubescente, 

 foliolis majoribus latioribusque ad 16 cm. longis et ad 6.5 cm. latis, grossius ser-

This species is closely allied to S. javanica Reinwardt, but it differs considerably 

 in. its sessile or nearly sessile flowers and in the larger and broader leaflets with
