The figure and description of this plant would indeed be imperfectly given 
in this work, were we not to publish supplementary ones to those which _ 
will be found at. T. 147. Our friend Mr Parker, the discoverer of the 
plant, has recently had the good fortune to receive from Demerara living 
plants, which, planted in water in the Liverpool Botanic Garden, have ; 4 
flourished in the greatest perfection. From these, it appears, that when 
the fructification becomes ripe, the fronds have decayed away. These 
fronds float on the water like the leaves of Trapa natans ; several pro- 
ceed from the same root, and are broadly ovate, 3-lobed, cut and notch- 
ed at the margin, thin, and somewhat membranaceous, the base tapers 
_ into a remarkably thick cellulose footstalk, having many small scales on 
the under side. The frond is proliferous in a most remarkable degree: 
every notch and cleft having the power of throwing out a new plant; 
and a piece torn from the parent, and suffered to remain in the water, 
becomes clothed, in a short time, with new plants, as seen at Fig. 1.. 
From the centre of the fronds, as at Fig. 3., the fertile stipes, which bears 
| the fructification, arises ; and till this fertile frond is fully grown, the 
---——s barren fronds retain all their vigour of form and colour; and in this 
_ state the plant is most beautiful. 
If kept j 3 the stove, this plant i is by no means difficult of 
-eultiv ation.
