PLANTS WITH TRAPS AND PITFALLS TO ENSNARE ANIMALS. 137 
some time after the creatures have entered the chambers the only remains of them 
that one meets with are claws, legs, bristles, and little amorphous lumps, their 
sarcode, flesh, and blood having vanished and left no trace, we must suppose that 
the absorption of nutriment from the dead prey here ensues through contact with 
the extended protoplasmic tentacular filaments as in the case of Rhizopoda, to

Big. 25.—Capturing apparatus in the Toothwort, Bartsia, and Butterwort, 
1 Piece of an underground leaf-shoot of the Toothwort. 2 Longitudinal section through the same; x2. 3 Longitudinal section 
through a leaf; x60. 4 Piece of the wall of a cavity; x200. 5 Plasmic threads radiating from the cells of the little heads; 
x540. 6 Subterranean bud of Bartsia; natural size. 7 Cross-section through part of this bud; x60. 8 The margin of 
a bud-scale in section; x200. 9 Piece of the epidermis of a leaf of Butterwort; x180. 10 Transverse section through the 
leaf of a Butterwort (Pinguicula alpina); x50. 11 Transverse section through Butterwort leaf; natural size. 
which these organs are so strikingly similar. It is not impossible that the sessile 
organs alone have the function of absorption, and that the stalked capitate 
structures serve for the retention of the prey; at least, this idea is supported by the 
circumstance that the former, which, as already stated, are much the scarcer, have 
vessels running to them connected by a peculiar barrel-shaped cell with the large 
elliptical tabular cells, whilst this is not the case with the capitate forms of 
structure. 
The openings of the chambers into the recess at the back of a Toothwort leaf 
being very narrow, only minute animals, such as Infusoria, Amcebe, Rhizopoda,
