458 SALICACEAE 



Var. ACUMINATA, F. B. White, 1. c. S. acuminata, Sm. E, B. t. 1434, 

 and Fl. Brit. iii. 1068. Syme, E. B. viii. 229, t. 1326. 



I have seen a plant which probably comes under this form near 



Wantage. 



I have here ventured to group under S. Smithiana various hybrids of 

 S. viminalis with caprea, cinerea, and aurita, but the synonymy of the various 

 forms will give the names of their supposed parents. It is quite likely that 

 some of the plants placed under Smithiana are ternary hybrids. 



S. Smithiana, which is kept as a distinct species in Index Kewensis, 

 is recorded for all the bordering counties except Wilts, but I have 

 seen it in that county in the Vale of Pewsey. 



S. cinerea, Linn. Sp. PI. 1021 (1753). Gh'ey WiVoiv. 



Top. Bot. 375. Syme, E. B. viii. 230, t. 1327. Nyman, 667. Fl. Oxf. 274. 

 Native. Sylvestral. Woods, hedges, damp bushy places, stream-sides, 

 occasionally on walls. Common and generally distributed. Shrub 

 or small tree. April. 

 First record. S. cinerea. Dr. Noehden, Mavor's Agr. Berks, 1809. This and 

 the var. aquatica are noticed by Mr. H. C. Watson in Brit. Contr. 187 1. 

 S. cinerea is very variable and hybridizes with aurita, caprea, purpurea, 

 viminalis, &c. 



Var. AQUATICA (Sm. E. B. t. 1437 and Fl, Brit. iii. 1065, as a species), 

 Fl. Oxf. 274, Syme, E. B. viii. 231, t. 1328, which is for the greater part 

 a hybrid of aurita x cinerea. 



1. Isis. Cumnor. Appleford. 2. Ock. Bagley. Radley. 



Tubney. Hagborne. 3. Pang. Pangbourn. 4. Kennet. 



Thatcham. Aldermaston. 5. Loddon. Near Wokingham, 



Watson. Near Twyford. Swallowfield. Bray. Ruscombe. 



Plants w^hich agreed with named forms of S. oleifolia, Sm. E. B. 



t. 1402, and Fl. Brit. 1065, Syme, E. B. viii. 231, t. 1329, have been 



seen in Bagley, Burghfield, &c. 



A form with narrow leaves was seen in woods at Tilcombe Green, 

 near Kintbury. 



S. cinerea is found in all the bordering counties. 



S. aurita, Linn. Sp. PL 1019 (1753). Round-leaved Willow. 



Top. Bot. 376. Syme, E. B. viii. 232, t. 1330. Nyman, 667. Fl. Oxf 275. 



Native. Sylvestral. Hedges, thickets, damp woods, and heaths. Not 



uncommon. Small shrub. April-May.
