TRILLIUM NIVALE. 
F. M. ANDREWS. 
In the year 1898 the writer transplanted twenty specimens of Tril- 
lium nivale from the “North Pike” road, about one mile north of Bloom- 
ington, to his yard. The purpose of this was to be able to study more 
conveniently certain structural features and observe as closely as pos- 
sible the period of anthesis over a series of years. 
A study of the habitat was made and all of the observed condi- 
tions as to soil, shade and other factors were duplicated closely. It 
was necessary to protect the plants at first by a low box frame, but 
the sides of this box stood at some distance from the plants and afforded 
no more shade to the plants than the rocks which originally surrounded 
the place from which the plants were taken. This distance between 
the plants and the sides of the box is evident to some extent in the

accompanying photograph (Figure 1). This photograph shows only 
one corner of the box and was taken five years after the transplanting 
had been done. 
The box was four feet square, made of one-inch poplar lumber, 
was twenty-five em. deep and had no bottom. It was found necessary 
later on to protect the plants at times by galvanized iron wire netting 
having meshes about one-half cm. square. 
The transplanting was done in early spring, care being taken to
