SALICACEAE. — SALIX 147 
Sect. 23. SERPYLLA Schneider, n. sect. 
A sectione Lindleyanae praecipue differt glandulis duobus florum c? bipartitis 
V. bilobis pseudodiseum 4-partitum formantibus, stylis florum 9 gracillimis 
bipartitis ramis divaricantibus, stigmatibus minimis emarginatis. 
Aecording to these characters the following species seems to represent a distinct 
group. 
123. Salix Serpyllum Andersson in Jour. Linn. Soc. IV. 55 (1860); in De Can- 
dolle, Prodr. XVI. pt. 2, 292 (1868). — Hooker f., Fl. Brit. Ind. V. 634 (1888). —

vini Sikkim: “ reg. alp., alt. 10-14090 [non 17000] ped.," J. D. Hooker (c? 
and 9 types). 
Having seen the types from the Kew Herbarium [Lachen, 10000’, June 3, 49], I 
agree with Andersson, who says: “ Distinctissima est species, crescendi modo (fere 
ut in Thymo serpyllo) ramis et foliis omnibus diversa." The fruiting aments are 
up to 4.5 em. long; while the young 9 catkins are only from 1-1.5 em. in length. 
Andersson describes the rachis of the c catkins as “ aureopilosa." I find only a 
grayish pubescence, otherwise his description is correct.

F rutices erecti, plerique parvi. Folia elliptico-lanceolata v. elliptica usque obo- 
vata, integra, mollia. Amenta plus minusve foliato-pedunculata; flores c" glandu- 
lis duobus instructi, antheris (an semper?) rubescentibus; flores 9 glandula una 
ventrali (v. interdum etiam dorsali) instructi, ovariis sericeo-lanatis pedicellatis, 
stylis distinctis saepe apice bifidis, stigmatibus bifidis oblongis. — 
This section shows a relationship with several other groups, and it is with some 
doubt that I refer to it S. floccosa Burkill and S. opsimantha Schneider.
