282 DROSERA BINATA. Cuar. XI 
Dorothy Nevill for a fine plant of this almost gigantic Australian 
species, which differs in some interesting points from those pre- 
viously described. In this specimen the rush-like footstalks of 
the leaves were 20 inches in length. The blade bifurcates at its 
junction with the footstalk, and twice or thrice afterwards, curl- 
ing about in an irregular manner. It is narrow, being only 
of an inch in breadth. One blade was 7} inches long, so that 
the entire leaf, including the footstalk, was above 27 inches in 
length. Both surfaces are slightly hollowed out. The upper 
surface is covered with tentacles arranged in alternate rows; 
those in the middle being short and crowded together, those 
towards the margins longer, even twice or thrice as long as the 
blade is broad. The glands of the exterior tentacles are of a 
much darker red than those of the central ones. The pedicels 
of al] are green. The apex of the blade is attenuated, and bears 
very long tentacles. Mr. Copland informs me that the leaves of 
a plant which he kept for some years were generally covered 
with captured insects before they withered. 
The leaves do not differ in essential points of structure or of 
_function from those of the previously described species. Bits of 
meat or a little saliva placed on the glands of the exterior 
tentacles caused well-marked movement in 3 m., and particles 
of glass acted in 4m. The tentacles with the latter particles 
re-expanded after 22 hrs. A piece of leaf immersed in a few 
drops of a solution of one part of carbonate of ammonia to 437 
of water had all the glands blackened and all the tentacles 
inflected in 5 m.. A bit of raw meat, placed on several glands in 
the medial furrow, was well clasped in 2 hrs. 10 m. by the mar- 
ginal tentacles on both sides. Bits of roast meat and small flies 
did not act quite so quickly; and albumen and fibrin still less 
quickly. One of the bits of meat excited so much secretion 
(which is always acid) that it flowed some way down the medial 
furrow, causing the inflection of the tentacles on both sides as. 
far as it extended. Particles of glass placed on the glands in the 
medial furrow did not stimulate them sufficiently for any motor 
impulse to be sent to the outer tentacles. In no case was the 
blade of the leaf, even the attenuated apex, at all inflected. 
On both the upper and lower surface of the blade there are 
numerous minute, almost sessile glands, consisting of four, eight, 
or twelve cells. On the lower surface they are pale purple, on 
the upper greenish. Nearly similar organs occur on the foot- 
stalks, but they are smaller and often in a shrivelled condition. 
The minute glands on the blade can absorb rapidly: thus, a 
piece of leaf was immersed in a solution of one part of carbonate
