flat along the creek, associated with sweet gum, pin oak, red oak, 
Schenck’s oak, white elm, black gum, black birch, ete. The soil 
here is a light colored hard and compact clay. In this same county 
it was noted on high ground about five miles southeast of Boonville. 
In Pike County near Ayrshire a tree over two feet in diameter was 
growing in a rather moist, sandy soil. In Posey County it grows to 
be a large tree and is found in low clay flats west of Hovey Lake 
north to Half Moon Pond, associated with pin, swamp and white oak. 
Ulmus fulva Michaux. Rep or Sirepery Hum. It has been noted 
that the fruit may ripen before the leaves expand. The fruit may 
be elliptical. 
Ulmus Thomasii Sargent. Rock or Hickory Etm. Trees observed 
on the terrace of White River north of Indianapolis, where it is 
associated with sugar maple, mature their fruit when the leaves are 
about two-thirds mature. The samaras measured 17.5—22.5 mm. in 
length. The year’s growth at this time was green and smooth. 
Celtis mississippiensis Bosc. This year a tree of this species sixty 
inches in circumference breast high was found in the Muscatatuck 
bottoms near Delaney in Washington County. 
Celtis pumila (Muhlenberg) Pursh. Hackperry. The forms in 
Indiana that have been referred to this species are not well understood. 
The form referred to under Celtis occidentalis on page 1438 as a 
“thick-leaved”’ form I now refer to the above species. Specimens 
similar to the last have been noted in Washington County on a sterile 
oak knob along Blue River near Big Spring. The same form is 
found on the limestone bluffs of Hamar Hollow, about three miles 
southeast of Mitchell in Lawrence County, where it is associated 
with Rhamnus lanceolata, both of which are mere shrubs from three 
to five feet high. It is a frequent shrub along the bluffs of the Ohio 
River in Floyd, Harrison, Crawford and Perry Counties. Unlike the 
other two species of hackberry that are found in Indiana, this species 
bears fruit when a mere shrub of four to six feet in height. Hundreds 
of specimens of this form have been seen, and the largest one found 
measured two inches in diameter breast high and twelve feet in 
height. The specimen was found at the base of the bluff of the 
Ohio River just west of Leavenworth. Here it is closely associated 
with Rhamnus caroliniana. The leaves are very variable as to 
texture, size and leaf margin. 
Magnolia acuminata Linneus. CucumBer. A few trees of this 
species were found on a ridge on the farm of Geo. W. Scott, about 
four miles southwest of Clear Spring, in Jackson County. Another 
tree in the same county is located on the farm of W. J. Robertson,
