12 REPORT ON THE BOTANY OF 
species. When it is borne in mind that this region is widely 
separated from the Allegheny Mountains, that it is not a high 
region, the presence of Adzes 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, JZztchella repens and Gaultheria procumbens were found. 
in abundance there. <Kalmia latifolia 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 Spzvaea aruncus was a very 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- 
auxit 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 * Celtis 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 see 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, 
Cheilanthes 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
