456 SALICACEAE 



As the Rev. E. S. Marshall remarks, the leaves and bark show strong 

 signs of trianclra. The facies is obviously that oi purpurea. 

 S. purpurea occurs in all the bordering counties. 



S. rubra, Huds. Fl. Angl. 364 (1762). 



S. purpurea xviminalis. S. Helix, Linn. Sp. PL 1017 (1753)? 



Top. Bot. 375. Syme, E. B. viii. 221, t. 1320. Nyman, 665. Fl. Oxf. 273. 



Native. Paludal. River-sides and wet places. Rare. Shrub. April- 

 May. 



First record. S. minima fragilis, fol. longissimis, utrinque viridihus nori 

 serratis, Ray, Syn. 238, 1690. 



1. Isis. Near Eynsham. 



2. Ock. Near Besilsleigh. 



3. Pang. Pangbourn, Hon. J. L. Warren. Tilehurst. 



4. Kennet. Padworth. Burghfield. 



5. Loddon. In the Osier Holts between Maidenhead and Windsor, 



Ray, Syn. I. c. Wargrave, S. Helix, Melvill. Loddon side. Near 

 Wokingham. 



I have only seen the S. rxibra, var. purpureoides, Gren. et Godr. Fl. 

 Fr. iii. 129, in Berkshire ; this variety is made up of hybrid plants in 

 which S. purpurea is the predominating partner, the leaves being 

 broader and less hairy than in the var. viminaloides, Gren. et Godr. 

 1. c, in which S. viminalis is more evident ; that is, in viminaloides 

 the leaves are narrower and longer and covered underneath w^ith 

 a greater amovint of pubescence. The form Forhyana (Sm. Fl. Brit. iii. 

 1041, as a species), Syme, t. 1321, I have seen near Wytham. 



In this case, as in S. virldis, I have kept a distinct heading for a hybrid 

 plant. 



S. rubra is recorded for all the bordering counties except E. Glouces- 

 tershire. 



S. viminalis, Linn. Sp. PL 1021 (1753). Osier. 



Top. Bot. 375. Syme, E. B. viii. 233, t. 1322. Nyman, 666. Fl. Oxf. 273. 

 Native. Paludal. Pond-sides, marshes, meadows, osier-holts. Com- 

 mon and generally distributed. Shrub or small tree. April-May. 

 First record. S. viminalis. Osier. There are three varieties, the 

 Spanish, the French [? S. triandra'], and the new kind, Mavor's Agr. 

 Berks, 1809. Plentiful at Blewbury, &c., Mr. J. Lousley in Russell's 

 Neivbury Cat. 1839. 

 The common osier is too frequently planted in Berkshire to require 

 localities ; occasionally it is seen in apparently native situations, and 

 is much less subject to variation than the preceding species. 



Var. stipularis (Sm. E. B. t. 1214 and FL Brit. iii. 1079, as a 

 species), Syme, E. B. viii. 225, t. 1323. Nyman, 666. Fl. Oxf. 273. 

 I have only seen this plant, which has broader leaves and large
