Caulescent, attaining about 24 cm. in height ; rhizome 

 woody, repent or ascending, rooting, covered with old stipules 

 above. Stems tufted, erect or ascending, leafy throughout, 

 slender, glabrous, bay-brown when dried. Leaves radical and 

 cauline, orbiculato-ovate, oval-orbiculate, ovato-reniform or 

 sometimes reniform, obtuse or rounded at the apex, cordate 

 at the base, depressed-crenate, membranaceous, glabrous but 

 usually very slightly puberulent on nerves above or on both 

 surfaces, densely punctate with minute brown dots on both 

 surfaces when dried, 2-5 cm. long, 2|-5i cm. broad, lower 

 leaves often slightly turned into reddish colour when dried ; 

 radical and lower leaves long-petiolate and the superior ones 

 shorter-petiolate and the apical ones very shortly so ; veins 

 4—5 on each side, arcuate above, the lowest one with a few 

 main veinlets on the outer side; petiole glabrous, attaining 

 about 10 cm. long in the radical leaves but attaining about 

 8 cm. long in the cauline leaves ; stipules ovato-lanceolate, 

 subulato-lancedate, or subulato-linear, acuminate, sub-densely 

 fimbriate with erect-patent glandular-tipped teeth, but rather 

 loosely fimbriate in the upper ones, membranaceous, glabrous, 

 about 1—2 cm. long. Flowers cauline (not radical), exserted 

 upon the leaves in the superior ones, long-peduncled, c£eruleo- 

 violascent, about 1^—2^ cm. across ; peduncle very slender, 

 glabrous, or puberulent above, attaining about 14 cm. long, 

 bracteate near the flower or above the middle ; bracts 2, op- 

 posite or approximate, subulate or subulato-linear, pauci-
