2040. Plukenetia. Named after Leonard Plukene.t, an English botanist, who published some valuable 
works, with an immense number of copperplates, of singular merit for their time. The names of two of these 
works are so singular as to deserve explanation. One was called Amaltheum botanicum. This word in Greek, 
AfjuctX^iKx,, was the name of the goat which suckled Jupiter. As its milk was exquisite and abundant, the 
word came to signify, among the ancients, the symbol of richness and abundance. The famous library of 
Atticus was called Amaltheum, on account of the number and variety of tlie books which it contained. In

Male and female flowers upon different plants. 
To this class many of the observations made upon the last are equally applicable. Like it, the genera would 
have been more conveniently distributed among previous classes. The genera it contains are chiefly trees, and 
many of them form the most valuable portion of the forests of all parts of the world. 
In Monandria is found the celebrated Pandanus or screw pine, which, with its strange spiral branches, con- 
stitutes one of the most singular features of the vegetation of the Isle of France. Diandria contains the 
valuable Salix ; Pentandria, the hop, the hemp, and the spinage. The black Bryony, and various palms have 
a station in Hexandria ; the poplar in Octandria ; the Papaw and the Bonduc tree in Decandria. Monadelphia 
is richly endowed with valuable trees, such as the yew, the Norfolk Island pine, the juniper, the nutmeg ; and 
it also contains the wonderful pitcher-plant of China.
