Indo-China, Sontoy Province, Moiint Bavi, Pételot 2611, July 2, 1940, in open 

 forests, altitude about 600 m, 



A species characterized by ils long petioled leaves laxly arranged on the 

 upper parts of the stems, the leaf blade being gradually narrowed upward 

 to the sharply acuminate apex, the broadly rounded basai lobes being 

 parallel or only slightly diverging, as well as by being glabrous throughout 

 except for the slightlv ciliate bracts. The perianth lobes are ovate, rounded 

 or broadly obtuse, glabrous on both surfaces, distinctly 7-nerved, and char- 

 acteristically densely papillate on the base inside.

Indo-China, Tonkin, Chapa, Pételot 25S4, April 1035, in mossy humus, open 

 forests, altitude about 1500 m. 



In gênerai characterized by being glabrous throughout, the leaves promi- 

 nently and laxly reticulate beneath, the perianth about 4 cm. wide, the 

 lower half of the lobes inside transversely verruculose, the lobes broadly 

 ovate or orbicular-ovatf , rounded, and about 2 cm. in diameter. 



Lecomte, FI. Gén. I ido-Chine 5: 53. 1910, admitted a single species of 

 Ihis genus from Indo-Jhina, Asarum Balansae Franch., type from Mount 

 Bavi ; this species is aiso represented by Pételot 2555 from the type locality. 

 (). C. Schmidt, Notizbl. Bot. Gart. Berlin 11: 100. 1931, recor'ded Asarum 

 caudigerum Hance from Tonkin and described A. Petelotii O. C. Schmidt 

 from Tarn Dao, Tonkin, based on Pételot 3891. With the description of 

 the above two new species the total number now known from Indo-China 

 is five.
