wild pine, Tillandsia, the leaves of which are hollowed ous at 
their base, so as to be capable of containing more than a pint of 
liquid. A traveller says, ‘by making an incision into the base 
of this leaf, and collecting the water in our hats, we could ob- 
tain a sufficient supply,for the relief of the most intense thirst.”

its lanceolate leaf; beyond the apex of the leaf a, the mid-rib 
extends in the form of a tendril; at the extremity of this tendril 
is the cylindrical cup or pitcher b, about six inches in length, 
and one and a half in diameter; it is furnished with a lid, ¢. 
This is usually found filled with pure water, supposed to be a 
secretion from the plant. Insects which creep into this cup are 
drowned in the liquid, except a small species of shrimp, which 
lives by feeding on the others. The Pitcher-plant is a native 
of Ceylon, where it is called monkey-cup, on account of its be- 
ing frequented by these animals for the purpose of quenching 
their thirst. 
Compound Leaves.

termed a compound leaf, as in the Rose. :
