PITCHER-PLANTS.

<cxtends on each side, and below all is the bottom of 

 the pitcher, which is smooth and without glands. 

 The surface of the conducting-shelf is furnished with 

 ihairs projecting downwards. 



Looking at this arrangement as that of a fly-catching 

 apparatus, it seems to be admirably adapted to the 

 purpose, the projecting ledge, the downward directed 

 hairs with which it is fur- 

 nished, and the incurved 

 •teeth of the rim, all present 

 •obstacles to the exit of any 

 insect which may enter. 



Small glands with six cells, 

 two of which are central and 

 four peripheral, are scattered b 

 over the under-surface of the 

 •lid and upon the rim. The 

 upper walls of the interior 

 immediately beneath the 

 ledge contain numerous 

 large glands of from thirty 

 to forty cells. The oblique curved elevations below 

 the glandular walls are studded with similar glands, 

 but nearly twice as large. Mixed with these are 

 smaller hyaline glands, which consist of a central 

 oval cell surrounded by two to four others ; the 

 appearance is somewhat that of stomata, but the 

 central cell, as Mr. Gilburt believes, is glandular, and
