338 SALICINE^:. [SAUX. 



much wrinkled pubescent and reticulate beneath, stipules reniform, cat- 

 kins short dense-flowered, male ovoid, female cylindric. 

 Moist copses, heaths, &c. ; ascending to 2,000 ft. in the Highlands ; fl. April- 

 May. A small bush, 2-4 ft., with straggling branches ; probably a form 

 of 8. Caprea, being so closely allied to sub-sp. cinerea that it is chiefly 

 distinguishable by its smaller size, reddish twigs, leaves rarely 2 in., very 

 much wrinkled, young reddish and crisped, often petioled, large stipules, 

 shorter catkins, A-f in., and narrower more tomentose capsule. DISTRIB. 

 Europe, Siberia, W. Asia. 



7. S. re'pens, L. ; leaves small oblong- or linear-lanceolate obtuse or 

 acute, margin recurved entire or serrulate shining and reticulate above, 

 silky or glaucous beneath, stipules Oor lanceolate, catkins cylindric-oblong, 

 scales spathulate, anthers at length black. S. faetida, Sm. 



Heaths, commons, &c. from Argyle and Aberdeen southwards ; ascending to 

 2,590 ft. in the Highlands ; fl. April-May. A small, straggling bush ; 

 brauches slender, elongate, erect or decumbent ; buds silky. Leaver exces- 

 sively variable, ^-1^ in., young always silvery silky. Catkins preceding or 

 appearing with the leaves, erect, short, sessile, rarely on lengthening 

 leafy peduncles -1 in., bracts leafy ; scales yellow-green or purple, silky, 

 always dark at the tip ; anthers yellow till the pollen is shed. Capsule 

 pedicelled, glabrous or silky. DISTRIB. Europe, Siberia. The following are 

 the chief British forms. 



VAB. 1, repens proper; stems decumbent below, flowering branches erect or 

 ascending, leaves appearing with the flowers elliptic-oblong quite entire silky 

 beneath tip straight, stipules 0, capsule glabrous. VAU. 2, fus'ca, L. (sp.); 

 stem suberect, branches spreading, leaves elliptic-oblong faintly serrate tip 

 straight ; the rest as in var. 1. VAR. 3, prostra'ta, Sm. (sp.) ; prostrate, 

 branches many slender, leaves appearing after the flowers faintly serrate 

 puberulous above glaucous and silky beneath, stipules minute or 0, capsule 

 silky. VAR. 4, ascen'deiis, Sm. (sp. ) ; stem decumbent, branches ascending, 

 leaves as in var. 3 but appearing with the flowers more silky beneath and tips 

 recurved, stipules ovate or lanceolate or 0, capsule silky at length glabrous. 

 VAR. 5. parvifo'lia, Sm. (sp.) ; stem as in var. 3, leaves and capsules as in 

 var. 4, stipules small ovate or 0. VAR. 6, argen'tea, Sm. (sp.); stem and 

 simple slender branches erect, leaves appearing with the flowers elliptic-ovate 

 quite entire densely silky and silvery especially beneath, tip recurved, capsule 

 silky. A large form, growing in sandy places. VAR. 7, rofinarinifo'lia, L. 

 (sp.) ; leaves 2-3 in., linear or linear-lanceolate faintly glandular-serrate or 

 entire glabrous or silky beneath, stipules ovate or lanceolate, catkins short 

 sessile dense, scales black, capsule tomentose. Said to have been found in 

 the last century by Sherard in bogs in Scotland. 



K. ambiff'va, Ehr. (S*. incuba'cea, L. ; S. re'pens, var. incuba'cea, Syme), is a 

 hybrid between S. auri'ta and S. reopens (Andersson), remarkable for the 

 reticulate leaves with recurved margins and large stipules. S. spathula'ta, 

 Willd., is referred by Andersson to a hairy form of this. 



** Capsule with a slender pedicel ; style distinct. 



8. S. ni'grricans, Sm. ; leaves thin ovate-oblong cordate or lanceolate 

 fiubacute reticulate above, stipules or J-cordate, catkins sessile or on short 

 leafy peduncles ovoid or cylindric, scales linear-oblong pilose. 



Hocks and banks of streams, from Aberdeen southwards to Norfolk and Here- 

 ford ; ascends to 2,300 ft. in the Highlands ; rare in Ireland ; fl. May-June.
