308 : -. PITTONTIA. 
orbicular but largest below the middle and the basal sinus 
closed, none of the lobes either lobed or toothed, all broader 
than long, very obtuse or almost truncate, obseurely undulate, 
or quite entire. 
A Georgian species, rare and little known. According to 
Wood » supposing his plant to be the same I have described— 
the leaf is sometimes without lobes: such plants probably 
young. My type is Mr. Harper’s n. 1146, from near Americus, 
Ga., 1901. The rootstock here, as in S. australis, appears to be 
hard-fibrous rather than succulent. 
5. S. GRANDIFLORA, . Sweet, Fl. Gard. 2 Ser. t. 147. This 
seems likely to prove a valid species ; for, although from “ Car- 
olina,” it can hardly displace either of my names here proposed 
for southern plants. Its rootstocks are indicated to be as 
fleshy as those of any of the northern kinds. 
6. S. MEsocHoRA. Corolla and large mature foliage of 5S. 
canadensis; rootstock stouter and very succulent: fruiting 
peduncle shorter: mature pod smaller by one-third, much more 
compressed, almost flat, not acuminate, of oblong-elliptic outline 
and merely acute. 2 
Wooded slopes along bluffs of the upper Mississippi and its 
tributaries in Wisconsin, lowa and Minnesota; type specimens 
as to fruiting stage recently sent from Winona, Minn., by Prof. 
J. M. Holzinger, i
