BOTANY: 
Abnormal Plant Growths.— Trillium grandiflorum Salisb., is 
noted for its variableness, but a specimen brought in by one of our 
pupils, this spring, exceeds anything I have seen in this respect. The 
flower is double, having two sets of sepals, and two of petals. Both 
sets of sepals are of the usual form and color. The outer petals are 
striped like ribbon-grass, except the half of one which is white. The 
inner ones are white, except a thread of green through the center of 
one. There sre three stamens—one normal, one a filament without an 
anther, and the other expanded into a half-sized petal, concave on one 
* side where a thread of gold, about the length of the anther, seems to be 
holding loyally to duty. The ovary is of usual size, the styles rather 
small—one smaller than the others. Near the top of one of the carpels 
arises an outgrowth about half an inch long, white, doubled together, 
and drawn over at the top like a hood. To add to the general confu- 
sion, there are, on the edges of this growth near the top, two pollen- 
bearing lines about an eighth of an inch long. 
A member of my botany class, Mr. Cheshire Boone, found a speci- 
men of Hepatica acutiloba DC., with two flowers on one scape. The 
second flower arises from the axil of a linear bract a little above the 
middle of the scape. It is on a peduncle an inch long, and is about 
half the size of the upper flower. 
Another unusual form found this spring is Viola palmata L., var cu- 
eullata Gray, with all of the petals emarginate.

The Approaching Meeting of the A. A. A. S.—The meeting of 
the American Association for the Advancement of Science, this year, 
from August 15th to 24th, promises to be of great interest to botanists. 
It is to be held in Brooklyn, N. Y., within a few hours’ ride of the 
homes and laboratories of probably one-half of the working botanists 
of the country, which may be counted upon as insuring a large meet- 
ing. Added to this is the fact that at this time will occur the first 
meeting of the American Botanical Society, which must attract many 
of our most earnest workers.
