DORSET PLANTS. 77 



Viola palustris, L. F. Moist woodland, Button Holms. V. 

 hirta x odorata. F. At two spots near Button Waldron. E. 

 Near Fontmell. 



V. silrestris, Reich. The commoner species on the chalk and 

 London Clay, flowering two or three weeks earlier than V. 

 Riviniana, Reich. F. Both occur at Edmondsham. The latter 

 is more frequent in heath districts, where I have not observed 

 the former at all. 



V. ericetorum x Riviniana. F. Railway bank near Dagham's 

 Road. V. tricolor, L. D. Field S. of Morden Decoy. The 

 type is rare in the county. A pure yellow form, which I have 

 no name for, occurs in chalky fields.

 fodder field, Compton Abbas, 1894. S. officinalis, L. E.

 Abbas and Fontmell. F. Longfleet to Parkstone.

 uncommon on the chalk, Shillingstone ; N. and S.W. of 

 Blandford. S. conica, L. F. In another spot at Parkstone (2 m. 

 from Mr. Molesley's locality), where this very rare plant has all 

 the appearance of being native. S. noctiflora, L. F. Two fields 

 between Foxholes Wood and the railway near Baileygate. Not 

 in the Flora.

 no localities. F. Ensbury ; near Cranborne ; Longfleet ;

 land ; Corfe Castle. C. tetrandrum, Curt. F. Abundant from

 Haven. C. arvense, L. F. Alderholt ; fieldside, Wallis Down.

 Hamworthy ; Wool Bridge. D. N. of Wareham. Var. sa/iva, 

 Boenn. F. Canford Cliffs ; Parkstone ; Heatherlands ; Ham-
