others characteristic of the Ozark or southeastern mountain 
region, quite an element of southwestern species and some 
that are distinctly southern. That the central Mississippi 
Valley is the meeting ground of these various floras is well 
known, and Jasper County, through its diversity of soil and 
topography, fairly epitomizes, and is typical of, the region.

CvsroPTERIS BULBIFERA (L.) Bernh. 647, 2964, 2977, 3169. 
This species is sometimes difficult to distinguish from Cys- 
topteris fragilis, as it seldom produces the characteristic 
fleshy bulblets in our area, and the fronds seldom exceed 20 
em. in length, but it differs from the next species in being 
broader at the base, thinner, and with segments less decur- 
rent along the rachis. It is found along moist shaded ledges 
of limestone bluffs. C. fragilis seems to prefer rich banks 
and shaded hillsides.
