deflexed Aoire.— Several species (?) allied to this are nearly or 

 quite scentless : V. permixia ( Jord.) liaa large glabrous glan- 

 dular-denticulate stip. ciliate towards the tip, short robust 

 stoles usually not rooting, fl. pale blue : V. sepincola (Jord.) 

 has large glandular-denticulate stip., longer somewhat rooting 

 stoles, and much darker flowers. These plants and their allies 

 seem quite different when growing, but are very difficult to 

 define. Some authors join them to V. hirta. — Common. P. III. 

 IV. Sweet Violet. E. S.? I. 



b. Stohs wanting or very short. 



3. V. hir'ta (L.) ; anth.-spurs nearly linear blunt, spur of the 

 cor. blunt hooked at the end, pet. entire or slightly emarginate, 

 1. cordate-ovate, stoles wanting. — M. B. 894. R. iii. — ^Anth.- 

 cells diverging below. Spur of the petals compressed, not 

 channelled. Fl. pale blue sometimes white, scentless. Fr.- 

 sep. roundly triangular, bluntish, as long as broad, more or less 

 cuiate, mostly downy. Bracts below the middle oftheflowei-stalk. 

 Stip. not hispid at the margin. Petioles with spreading hairs. — 

 (3. calcarea (Bab.) ; fl. smallei', ped. much longer than the leaves, 

 Sep. oblong-ovate. — V. sciaphita (Koch P), found by Newbould 

 at Harlton near Cambridge, differs by having larger 1. with 

 the basal lobes more spreading and (moid glabrous capsules. — 

 Common on limestone. B. Gogmagog Hills. Portland. P. IV. 

 Hairy Violet. E. S. I. 



*** Stigma hooked ; beak horizontal. Having a stem. 

 Fruitstalks erect. 



t Without a true sohole. 



4. V. sylvat'ica (Fries) ; anth.-spurs narrowly lancet-shaped 

 (5 times as long as broad), cor.-spur blunt, caps, glabrous, 1. 

 broadly cordate,_/?owmn^ branches axillary from a short Jlower- 

 less central rosette of leaves. — Fl. scentless. — It is probable that 

 the following are distinct species : — a. V. Rdohenbachiana 

 (Bor.); 1. cordate-prolonged, calycine appendages small be- 

 coming indistinct, pet. oblong narrow (lilac), lower with few 

 parallel nearly simple veins at the base, spur compressed entire 

 (usually darker than the petal). E. B. S. 2986. — ,8. V. Riviniana 

 (K.) ; 1. broad cordate-acute, calycine appendages broad and 

 squarish persistent with fruit, pet. broadly obovate {blue), lower 

 with many branched darh veins at the base, spur thick (usually 

 yellowish white). E. B. 620. Curt. i. 182. V.Jlavicornis (Forst.) 

 is a dwarf form having small 1. and large flowers. — Common on 

 hedge-banks or in thickets. P. IV. V. Wood-Violet. E. S. I.
