44 AMERICAN FERN JOURNAL 
River, is a wonderful rocky hammock; one writer calls 
it “‘a Paradise of ferns.’ Here are all the rock-loving 
ferns of the West Coast that can be found in this lati- 
tude, among them the rare creeping fern with so many 
different names of which the most recent is Goniopteris 
reptans. It has two sorts of fronds, one erect and stout, 
the other long and tapering, and bending over to the 
ground to take root like the well known Walking Leaf 
of the Northern woods. 
Another fern of unusual appearance is the Tectaria 
trifolata, with fronds 12’-18’ long, 6’-12’ broad. It 
has scant resemblance to the usual form of a fern, but 
the large round sori are very evident and unmistakable.

Greene County lies in the southwestern part of Mis- 
souri, its western and southern borders being about 55 
and 40 miles distant, respectively, from the Kansas and 
Arkansas borders. 1t occupies the Missouri summit of 
that geologically most ancient part of the central Mis- 
sissippi Valley, the Ozark Uplift. The central and 
western parts of the county consist chiefly of a nearly 
level prairie, given over to agricultural uses and now 
possessing but little of the original forest, while the 
eastern, northern, and southern parts are composed 
largely of low, rocky, thinly forested hills. The rocks 
are chiefly Carboniferous and Ordovician limestones, 
but sandstone is found occasionally. 
The flora of this part of Missouri possesses many 
features of interest, for this county is one of those several 
hundreds in the United States which are “‘peculiar”’ in be- 
ing the meeting point for the eastern, western, northern, 
and southern floras. It is a fact, nevertheless, that the
