Drosophyllum, but differs in the following points. I 
could detect no sessile glands; nor would these have 
been of any use, as the upper surface of the leaves is 
thickly clothed with pointed, unicellular hairs directed 
upwards. The pedicels of the tentacles do not include 
spiral vessels; nor are there any spiral cells within the 
glands. The leaves often arise in tufts and are pin- 
natifid, the divisions projecting at right angles to the 
main linear blade. These lateral divisions are often 
very short and bear only a single terminal tentacle, 
with one or two short ones on the sides. No distinct 
line of demarcation can be drawn between the pedi- 
cels of the long terminal tentacles and the much 
attenuated summits of the leaves. We may, indeed, 
arbitrarily fix on the point to which the spiral vessels 
proceeding from the blade extend; but there is no 
other distinction. 
It was evident from the many particles of dirt stick- 
ing to the glands that they secrete much viscid matter. 
A large number of insects of many kinds also adhered 
to the leaves. I could nowhere discover any signs 
of the tentacles having been inflected over the cap- 
tured insects; and this probably would have been seen 
even in the dried specimens, had they possessed the 
power of movement. Hence, in this negative cha- 
racter, Roridula resembles its northern representative, 
Drosophyllum. 
ByBuis. 
Byblis gigantea (Western Australia).—A dried 
specimen, about 18 inches in height, with a strong 
stem, was sent me from Kew. The leaves are 
some inches in length, linear, slightly flattened, with 
a small projecting rib on the lower surface. They 
are covered on all sides by glands of two kinds
