FERNALD: ANTENNARIA IN NEW ENGLAND. 
249 
young pistillate flowers of A. canadensis ancl A. neodioica in 
July, when no staminate flowers could be discovered. 
As already stated, propagation by stolons is highly developed 
in these Antennarias. This is so much the case that we find the 
plants growing in extensive colonies apparently all originating 
from one central plant. Or at other times colonies of different 
species originating near together soon produce an almost insepara¬ 
ble tangle of stolons and offsets. It has been suggested that as 
this vegetative method of propagation has become so highly devel¬ 
oped, the necessity of reproduction by seed has been diminished; 
and that now, though the plants appear to produce good seed, and 
may sometimes do so, they are most often spread, as seems to be 
the case, by the numerous stolons. If these plants were often 
reproduced by the abundant akenes, we should expect to find 
scattered young plants in large numbers; but such scattered indi¬ 
viduals, if they occur at all, are certainly very unusual. Instead 
we find colonies of plants near together, and in the case especially 
of the small-leaved species they form extensive mats. 
The question is by no means solved: it is rather merely opened. 
It is such a problem as can be settled only by careful cultures; but 
for those who, during the spring and early summer, can give it 
critical attention, it offers a most attractive and productive field 
for investigation.
