1918] Blake,— Variety of Smilax glauca 79 
verulent. The former, if one may judge from the material in the 
Gray Herbarium, ranges from Massachusetts to North Carolina, and 
occurs again in Florida and Oklahoma. The latter is represented in 
the Gray Herbarium and the United States National Herbarium by 
material from Virginia to northern Florida (Jacksonville), west to 
Texas (Houston) and north to Ohio and Illinois. The material of 
this papillose form was separated by the writer in the two herbaria 
mentioned under a manuscript name, the smooth and more northern- 
ranging plant being taken as the typical form of the species. Publi- 
cation of the variety was delayed, however, as the writer expected to 
have an opportunity to examine the type in Walter’s herbarium 
in the British Museum. However, careful examination of the Walter 
Herbarium showed no specimen representing Walter’s name. In the 
De Candolle (general) Herbarium at Geneva, however, I found a good 
specimen of the plant with leaves densely pulverulent beneath, which 
was labeled “Smilax sarsaparilla L. Carol. merid. Fraser.” It seems 
to the writer that this specimen of Fraser’s may be taken, in the lack 
of any direct evidence from the Walter Herbarium, as indicating the 
varietal identity of Walter’s Smilax glauca! It is not suggested that 
this plant of Fraser’s is in any sense a type of Walter’s S. glauca, but 
merely that, coming as it does from somewhere near the type locality 
of Walter’s plant, all means for absolutely identifying which are now 
forever lost, it affords sufficiently strong presumptive evidence of the 
identity of Walter’s S. glauca with the papillose form to justify the 
restricted use of the name in this sense. To this it may be added that 
the papillose form is much the commoner of the two south of Virginia 
and that the smooth-leaved form, so far as is shown by the herbaria 
consulted, is not found in South Carolina. 
The two varieties of Smilax glauca here recognized may be distin- 
guished as follows. 
SMILAX GLAUCA Walt. var. genuina: foliis subtus dense papillosis 
vel hirtello-pulverulentis.— S. glauca Walt. Fl. Car. 245 (1788), 
as here restricted.— Viretnta: Bedford Co., 1871, Curtiss (U. S.?). 
Norra CAROLINA: near Waynesville, 900-1500 m., 1910, Standley 
5513 (U.S.), 5589 (U.S.); Biltmore, 1896-97, Biltmore Herbarium 1322, 
1322b; Swain Co., 515 m., 1891, Beardslee & Kofoid; Sunburst, 
Haywood Co., 1911, House 4610. Sours Carora: Fraser (hb. DC.) 
1 The description by Walter of his plant as with ‘‘foliis . . laevibus” probably refers to their 
unarmed character rather than to glabrosity.
