12 REPORT ON TIE BOTANY OF 
species. When it is borne in mind that this region is widely 
separated from the Allegheny Mount:ins, that it 1s not a high 
region, the presence of Adres Canadensis will be unexpected ; 
but this makes a large growth in the gulches of Edmonson 
county. The //ex opaca attains the size of fifteen to eighteen 
inches in diameter, and forty to fifty feet in height. ‘The little 
shrubs, JJitchella repens and Gaultheria procumbens were found 
in abundance there. Kalmta /atifolia is abundant. ‘The 
Ptelea trifoliata grows on the Nolin. I mention this to say 
that I noticed that the petals did not open in all instances, but 
cohered at their apices, and were pushed off by the stamens 
and pistils as in some species of the vitis genus. 
The Spiraea aruncus was avery common plant, and I noticed 
a feature of it which I have never seen referred to by any one; 
it was the occurrence of a small deciduous bractlet on each 
pedicel, but not touching the flower. The Leavenworthia Mich- 
auxii was collected by me near the town of Glasgow Junction, 
just northwest of town, growing in a nearly filled-up sinkhole. 
This is quite a rare plant, and but few specimens were found. 
Trifolium reflexum occurs in several localities between the 
railroad and Mammoth Cave, which is in the eastern part of 
Edmonson county. I mention it because I have never found so 
many specimens in any one locality before, and also to make a 
note of the fine rose-pink color it everywhere had. The variety 
of Celt’s occidentalis, called pumila, commences to appear in 
Barren county, and extends everywhere through the country 
as far as Hopkinsville, in Christian county. I did not sée the 
ripe fruit; but shrubs ten feet high were not uncommon, with an 
abundance of fruit. The leaves are thin, smoother than those 
of the large form, and much tapering. I did not see a large 
tree of Celtis occtdentalis anywhere in this section such as are 
everywhere seen in creek bottoms north of the Ohio. Among 
ferns, I found, in Barren county, growing on the extreme east- 
ern end of the sandstone ridge, under which is Short Cave, 
Chetlanthes vestita. The hairs on this fern were distinctly 
jointed, and between each joint much flattened; but the con- 
tiguous sections flattened in different planes. This character
