ART. IV.—NOTICE OF THREE SPECIES OF — 
FOUND IN THE VICINITY OF BOSTON. „By 
TESCHEMACHER. Read Dec. 4, 1837. 
Tuere are many of the native plants of America, 
which can only have been studied by the plurality of 
European Botanists, through the medium of dried speci- 
mens ; and the observations on which, in the Botanical 
works published in this country, are sufficiently meagre, 
not indeed, from any want of ability in the authors, but 
simply because the plans of their publications did not 
admit of more copious or minute descriptions. Several 
of these are, no doubt, destined to remain unexamined 
properly, for a length of time. The successful raising 
from seed, transplantation, and cultivation of them, even 
in their native country, is by no means an easy task ; 
they are, therefore, not likely to become common enough 
in the living state, in Europe, to invite that rigid and 
thorough examination of their habits and structures, 
which, in the present state of Botanical science, is so 
necessary for a perfect description of them. This 
knowledge and information must consequently be sought 
for and obtained here, and will, no doubt, be highly wel- 
come, as well as expected, by their European brethren, 
from those Botanists, who, by vicinity to the habitats of 
rare and curious plants, may be enabled to study and 
explain their natural habits or variations. 
It appears, that a true knowledge of the seminal 
varieties, of the variations produced by cultivation, and 
of the earliest tendencies to exhibit change in the dif- 
ferent parts of the vegetable structure, derived altogether
