1905] Fernald,— Drosera rotundifolia 9 
arbor-vitz forest, occupying an area of perhaps a half acre. Occa- 
sional normal plants of Drosera rotundifolia were found but these 
were always taller and coarser and far less abundant than the plant 
with foliaceous carpels. That this little plant maintains its peculiar 
character was shown not only by its distribution throughout one end 
of the bog, but by the shrivelled remnants of similar inflorescences on 
scapes produced in past years. 
Whether the plant reproduces itself by means of the peculiarly 
developed carpels cannot now be stated. Living material now being 
studied at the Ames Botanical Laboratory and forming the basis 
.for Dr. Leavitt’s notes on page 14 will doubtless demonstrate this 
point. The plants, however, are not without their own method of 
abundant reproduction, for many of the specimens showed, springing 
from the decaying leaf-blades or the injured petioles, young plants 
such as have been already described by various observers. 
The dwarf plant perpetuating itself and occupying a considerable 
area almost to the exclusion of normal Drosera rotundifolia may be 
called 
DROSERA ROTUNDIFOLIA, var. comosa. Dwarf, the scapes 2 to 8 
cm. high: leaves comparatively small, the blades 3 to 7 mm. long: 
inflorescence 1- to few-flowered, subcapitate: calyx crimson or 
roseate: petals greenish to crimson, sometimes foliaceous : carpels 
in maturity developed into green glandular broadly obovate or oblate 
petioled leaves: other portions of the inflorescence occasionally 
modified. — Wet boggy margin of a marl-pond, near the mouth of 
Grand River, Gaspé County, Quebec, August 13, 1904 (J. F. Collins, 
M. L. Fernald and A. S. Pease). Type in Herb. Gray.

THE earliest authentic records that we have of the presence of 
prickly lettuce in this country are three specimens collected in 1863 
and 1864, in the vicinity of Cambridge, Massachusetts, and now in
