Rudbeckia hirta, L.—I collected J uly 28, 
1882, in Shelburne, N. H., a specimen of Rud- 2 
beckia hirta, in which the tubular disk flowers nats 
were all changed to ligulate flowers, nearly =" 
twice their ordinary length. The ray flowers Bh 
were as usual. The accompanying sketch 
illustrates the flower.—WaLrer DEANE, Cam- 
bridge, Mass. 
Variation and Human Interference.—Drar Eprror—I have this spring 
received from one source wild specimens of Thalictrum anemonoides, with full 
double flowers ; from another, Epigea, in the same condition. As these varia 
tions can not well be regarded as advantageous to the plants themselves, will 
you report the case to Dr. Sturtevant, who has made an acute suggestion about 
such things, and ask him if we are to infer that the aborigines of Maryland and 
New Hampshire were in former times floriculturists ?—A. G. . 
What a Lilac Bush did.—Two cut stones forming a part of a corner foun 
dation of Dr. Gray’s residence at Cambridge have been misplaced by a lilac 
two feet long. These stones form one end of the wall. In the joint between & 
the lower stone and the main body of the wall the lilac sprout established it — 
self. The bush, now searcely more than an inch in diameter, has forced his 
t 
ment.—L, H. Barney, Jr
