nato, moral )ranacoouR, nnnnt(;ly glandnloso-ciliatcd on tho margin, shortcir 

 than tlie stipnle-", chestnnt-colonnMl. Leaves .1-5, erect or ascending, 

 long-[)etioled, siiLreniform-cordate, suddenly short-acuminate with an acute 

 or acutisli tip, aurick'd with large and oval lobes and a deep not wide 

 sinus, crenato-serrate, thickly memliranaceons, thinly pubescent above, 

 pilosnlo-pubescent beneath, concoldnjus, with loose veins, about 5-10 cm. 

 long, 5-91 CQi. wide, but smaller in size and the basal lobes involute in 

 flower; petiole longer tlian tlie blade, exalate, glabrous, but puberulent 

 above, 9-16 cm. long, but 7-13 cm. long in flower ; stipules pale, free, 

 suljulato-lanceolate, acuminate, very thinly membranaceous, very delicately 

 loose-veined, minutely glanduloso-ciliated, 7-11 mm. long, 2-4 mm. wide. 

 Peduncles erect, equalling the l(\aves in ](Migth in flower, l)ut shorter in 

 those (if cleistoganious tlowers, glabrou>j, bracteate above the middle; brac- 

 teoles '2, ap[)ruxiinate, subulate, acuminate, thin, glanduloso-subciliated- 

 mnrgined bciow, 5-S mm. long. Flower large, about 2-2^ cm. across, 

 liglit lilac. Sepals oblong, obtuse, thin, glabrous, with 3 main nerves 

 and loose delicate veinlets, S-9 nuii. long, 2A-31 mm. broad; basal auricles 

 sul)rectangular, truncate often with more or less sinuate margin, glabrous, 

 about 2-3 mm. long, but smaller and obtuse narrow-oblong in the lateral 

 ones. Petals obovate or broadly obovate, attenuated at the base, round- 

 ed or sometimes subretuse at the apex, about 15 mm. long, the lateral 

 ones slightly bearded; calcar short, scrotiform, shorter than sepals, 3^-4 mm. 

 long, 3i-5 mm. wide. Connective-tip broadly ovate, obtuse ; appendages 

 lunato-falcato, obtuse, curved downwards, 21-3 mm. long. Ovary ovate, 

 gradually acute ; style slightly longer than the ovary ; stigma obovato- 

 deltoid, concave, the beak distinctly protruded. Capsule large, nutant, 

 elliptical, acute, glabrous, about l^-l^ cm. long. Seeds olwvoid, smooth,

Very closely allied to Viola vaginaia Maxim,, but differs from it by 

 its pale stipules, bearded petals, and entire or subsinuate-truncate-margined 

 calyx-appendages. The leaves of /'. var/inata Maxim, are entirely glabrous 

 on the upper surface, whili^ those of my species are hairy on both sur- 

 faces.
