Acaulescent, small, the simple ascending rootstock rather 

 small for the plant, closely jointed : leaves few, small, from 

 ovate-reniform to subcordate-ovate, ^ to i inch long at time of 

 petaliferous flowering, the undeveloped ones cucullate, all very 

 regularly crenate, glabrous and shining above, mostly sparse- 

 hirsutulous beneath and on the petioles, these in the earliest 

 not longer than the blade, in the later more than twice as 

 long : flowers very few, often i only ; peduncles hirsute, 

 minutely bracted below the middle : sepals small, lanceolate, 

 veinless, serrate-ciliolate : corolla large, more than y^ inch 

 broad, rich purple ; the upper pair of petals much the largest, 

 obovate, the middle pair narrower in proportion and strongly 

 bearded with long cylindric hairs, the odd one as long as 

 these and a trifle broader. 



Growing with V. blanda under trees north of the road 

 running from Rockcliffe to Beechwood. The plants grow 

 singly and are generally one-flowered. Collected in the 

 spring of 1901 and in fruit in September by Dr. J. Fletcher

 from cordate-reniform to broadly cordate with deep and often 

 almost closed sinus, subserrately crenate, the more strictly
