98 . WILSON EXPEDITION TO CHINA 
subamplectentem 4-5plo superantes; stigmata parva, subsessilia; bracteae late 
ovatae, subacutae, laxe villosulae, pedicello vix aequilongae v. deciduae. 
CHINA. Fokien: without locality, Dunn's Exped. to central Fokien, April 
to June 1905 (Hongk. Herb. No. 3509; with fruits). 
This specimen is named S. tetrasperma Roxburgh in the Hongkong Herbarium. 
1t seems to belong to this section, but differs widely from all the other species in its 
small leaves. Without having seen young 9 and also c' flowers the real relation- 
ship of the new species cannot be established. S. tetrasperma Dunn & Tutcher from 
Kwangtung, “muddy banks of the Canton River; Shekmun near Canton," may 
be our new species.

Arbores v. frutices alti. Folia pleraque magna, lanceolata v. ovalia, saepissime 
acuminata, iis sectionis 1 similia, juvenilia saepe viscosa; petioli saepe glanduliferi. 
Amenta œ subpraecocia v. coetanea, satis densiflora, floribus pleiandris, glan- 
dulis duobus ut in sect. 1, bracteis concoloribus; amenta 9 floresque ut in sect. l; 
glandulae duae, distinctae!

CHINA. Southeastern Szech'uan: Nan-ch'uan, A. von Rosthorn (No. 
1511, type; with fruits). 
I have seen only a photograph and one leaf of the type specimen of this species. 
According to the author S. dictyonéura belongs to sect. Safsaf; he describes the 
glands as follows: “glandula brevi stipitem 6-plo longiorem amplectente bi- 
partita parte postica lata integra parte antica tripartita." To me it seems al- 
ways very difficult to form an opinion from withered glands of fruiting specimens. - 
It would be a very peculiar fact if an African species like Salix safsaf F orskal had 8 
MN central China. I suppose that S. dictyoneura stands very near S. Wil- 
ii Seemen.

vinee d does not embrace the pedicel, while in S. glandulosa Seemen and other 
les this gland is very similar to the ventral d of the first section. Thes
