AN EASY METHOD OF PROPAGATING DROSERA FILIFORMIS (Plate 8.) — 
While cultivating Drosera filiformis, Raf., for experimental work I 
learned, quite by accident, that the quickest way to obtain new plants is by 
making cuttings. I grow all my Drosera species in a greenhouse where 
the temperature is kept low. Atsome time or other parts of the leaves 
of Drosera filiformis were broken off and allowed to lie on the sand 
where they fell. In the course of a few weeks these parts were ob- 
served to be giving off young plants at close intervals. This method 
of obtaining new plants may prove valuable to botanists who are far 
removed from the habitat of Drosera filiformis, and wish to keep a 
large supply of the species in a living state for experimental purposes. 
Drosera intermedia var. Americana, D. rotundifolia, and D. binata 
will also give off new plants if leaves are placed on sand or moss. D. 
rotundifolia has been reported (Bull. Torr. Club, 1892, p. 295) with 
young plants growing out of its leaves, and I have seen specimens of a 
similar kind collected in late July. It would seem that this species, at 
least, has a tendency to propagate itself naturally by other means than 
seed. Whether D. f/fformis and D. binata do the same in a wild state 
I am unable to say, although it seems highly probable. — OAKES AMES,

and B, young plants growing from the leaves; fig. F, longitudinal section of one of 
the young plants at point of origin. D. filiformis: figs. C and D, portions of leaves

VACCINIUM ULIGINOSUM AT A LOW ALTITUDE. — Some time ago I came 
across a large patch of Vaccinium uliginosum, growing at an altitude of 
three or four hundred feet in the town of Farmington, Maine. This 
species, generally found in the eastern states only on the alpine sum- 
mits of New England and New York, seemed as much at home at this 
lowland station as if it had been at a much higher altitude. The leaves
