CHAPTER XII. 
On THE SrructuRE AND MovEMENTS OF SOME OTHER SPECIES OF 
Drosera. 
Drosera anglica— Drosera intermedia — Drosera capensis—Drosera 
spathulata— Drosera _filiformis— Drosera binata — Concluding 
remarks, 
I EXAMINED six other species of Drosera, some of 
them inhabitants of distant countries, chiefly for the 
sake of ascertaining whether they caught insects, This 
seemed the more necessary as the leaves of some of 
the species differ to an extraordinary degree in shape 
from the rounded ones of Drosera rotundifolia. In 
functional powers, however, they differ very little. 
Drosera anglica (Hudson).*—The leaves of this species, which 
was sent to me from Ireland, are much elongated, and gradually 
widen from the footstalk to the bluntly pointed apex. They 
stand almost erect, and their blades sometimes exceed 1 inch 
in length, whilst their breadth is only the 1 of an inch. The 
glands of all the tentacles have the same structure, so that the 
extreme marginal ones do not differ from the others, as in the 
case of Drosera rotundifolia, When they are irritated by being 
roughly touched, or by the pressure of minute inorganic par- 
ticles, or by contact with animal matter, or by the absorption of 
carbonate of ammonia, the tentacles become inflected ; the basal 
portion being the chief seat of movement. Cutting or pricking 
the blade of the leaf did not excite any movement. They fre- 
quently capture insects, and the glands of the inflected tentacles 
pour forth much acid secretion. Bits of roast meat were placed 
on some glands, and the tentacles began to move in 1 m. or
