on veins and near the margin, the lower face densely tomentulose 

 with white somewhat tangled hairs, and when young particularly 

 softly and densely white tomentulose. Petioles rather densely 

 tomentose 2-5 mm. long. Cymes numerous subsessile or with a 

 peduncle of almost the length of one centimeter. Pedicels densely 

 tomentose-hirtellous. Bracts numerous, linear, hirtellous. Sepals 

 linear-lanceolate, hirtellous, or tomentulose almost or equaling 

 the corolla segments. Corolla 2-3 mm. long and wide, broadly 

 campanulate with spreading whitish segments rounded at the apex. 

 Pods arising in pairs successively from stem and branch cymes, 

 rather small 6.5- 11 cm. long subequal, those produced later being 

 larger. 



I select as type No. 9733 of the Herbarium of the University 

 collected along a branch of the Michigan Central Railroad near 

 the boat house at Notre Dame. The specimen was collected July 

 8, 19 1 2. As fruit-type I may designate No. 10304 gathered along 

 the road between Cartier Athletic Field and the Ice-house. The 

 plant is very abundant in this locality, but fruiting specimens are 

 never numerous. What will probably prove to be the same species, 

 I have found on the east shore of Upper Chain Lake, about 10 

 miles west of South Bend, Ind. I noticed and carefully examined 

 this plant several days before I found the flowering type referred 

 to, but failed to collect specimens. I expected to gather such on the 

 return from the north end of the lake and later decided to botanize 

 on the west shore. As I left this part of the country shortly after, 

 and did not return until late in fall, I have had as yet no occasion 

 to obtain specimens from the Chain Lake region.
