Perennial, acaulescent. Khizome subterranean, slender, creeping, ascend- 

 ing above, gracile and rarely branched in the lower portion, loosely with 

 delicate ramose roots throughout, about 2-6 cm. long, hard, approximately 

 with notched numerous nodes having old rusty-brown stipules and the base 

 of petioles. Leaves 1 to 4, long-petiolate, reniform, suborbiculato-reniform, 

 or ovato-reniform, deeply cordate with a close or open sinus at the base, truncate 

 or truncato-obtuse or shortly produced or angulato-obtuse with a callose end at 

 the apex, depressed-crenate with papillato-subcallose point, membranaceous, 

 very thinly pubescent or glabrate above, glabrous beneath, loosely ciliated 

 or glabrous on margin, 16-22 mm. long, 18-24 mm. broad in flower, but 

 afterwards attaining nearly 45 mm. long, 54 mm. broad ; nerves delicate^ 

 7-9-radiato-palmate, with loose veinlets ; petiole slender, gracile, wing- 

 less, glabrous, about 3-6 cm. long in flower, but then attaining about 

 9 cm. long ; stipules erect, subulato-deltoid, usually produced-acuminate, 

 shortly adherent to the petiole, membranaceous, loosely papilloso-ciliated on 

 margin, brown, glabrous, about 2 mm. long. Peduncles 1-3, erect, usually 

 exceeding the leaves, slender, gracile, glabrous, about 2-9^ cm. long, bracteolate 

 above the middle ; bracteoles 2, opposite or approximate, linear-subulate^ 

 acuminate, glabrous, papillose on the basal margin, 2-2 1 mm. long. Flower 

 small, about 8 mm. across, white. Sepals oblong- to ovato-lanceolate, acutish- 

 obtuse at the apex, narrowly hyaline and sometimes minutely loose-ciliated 

 on margin, glabrous, delicately 3-nerved, about Z\ mm. long excepting the 

 basal auricles, lateral ones somewhat shorter ; basal auricles depressed-semi- 

 orbicular, rounded at the apex, entire, \-\ mm. long. Upper and lateral 

 petals obovato-oblong, attenuated below, rounded-obtuse at the apex, beard- 

 less, about 8 mm. long, 3 mm. or a little more wide ; the lower petal slightly 

 shorter and broader, obovate, emarginate at the apex, marked with dark 

 purple veins as are the lateral petals ; calcar short and small, shorter than 

 sepals, ovato-semiorbiculate, 1 mm. and a little more long, 1^ mm. broad. 

 Stamens 2 mm. and a little more long ; connective-tip oblong-ovate, obtuse, 

 hardly shorter than the anther-cell; appendages minute, short, subdeltoid- 

 seraiorbiculate, rounded-obtuse, thicker towards the margin, \ mm. long. 

 Ovary ovoid, tapering above, glabrous, 1 mm. and a little more long ; style
