BRYOPHYLLUM CALYCINUM. 
Class. Order, 
OCTANDRIA TETRAGYNIA. 
This is a native of the Moluccas and of the 
Isle of France, where it was found by 
Sonnerat. It grows about four feet high, 
and flowers in a large terminal panicle. 
The whole plant possesses curious proper- 
ties: the calyx, which has the appearance 
of a small open bladder, is produced first, 
and the corolla grows out of it a consider- 
able time afterwards: the leaves have the 
power of producing young plants from the 
notches at their edges, and this power is 
not destroyed or lost by cutting or breaking 
them into pieces. It requires the stove, 
and should be potted in rich loam. 
Our late friend, Dr. Heyne, detected 
another remarkable property in the leaves ; 
they have a sour taste, resembling sorrel, in 
the morning, while in the middle of the day 
they become tasteless, and somewhat bitter 
towards evening. This change is ascribed 
by him to the absorption of oxygen during
