on the tips of the leaves, and some very short. The glands 
also differ much in size and are somewhat elongated. They 
are supported on multicellular pedicels. 
This plant, therefore, agrees in several respects with 
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 pinnatifid, the divisions pro- 
jecting 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 
pedicels of the long terminal tentacles and the much attenu- 
ated 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 sticking 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 captured insects; and this probably 
would have been seen even in the dried specimens, had they 
possessed the power of movement. Hence, in this negative 
character, Roridula resembles its northern representative, 
Drosophyllum.

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—sessile ones arranged in rows, and others supported 
on moderately long pedicels. Towards the narrow summits 
of the leaves the pedicels are longer than elsewhere, and 
here equal the diameter of the leaf. The glands are purplish, 
much flattened, and formed of a single layer of radiating 
cells, which in the larger glands are trom forty to fifty in 
number. The pedicels consist of single elongated cells, with 
colourless, extremely delicate walls, marked with the finest
