Cult. The leaves of most of the species of this genus are 

 sensitive to the touch, and are therefore all worth cultivating for 

 curiosity. They thrive well in a mixture of loam and peat, and 

 young cuttings will root if planted in a pot of sand, with a bell- 

 glass placed over them in heat. Some of the kinds ripen seeds 

 in abundance, by which they are easily increased. The seeds of 

 the annual kinds require to be sown in pots, and the pots placed 

 in a hot-bed, and when the plants rise to the height of 2 or 3 

 inches they should be potted off' separately into small pots, and 

 shifted from size to size of pots as they grow, giving the plants 

 plenty of heat and moisture.

LIN. SYST. Polygamia, Monce'cia. Flowers polygamous. Calyx 

 5-toothed. Petals 5, connected together into a 5-cleft corolla. 

 Stamens numerous, exserted, sometimes joined together a short 

 way at the base, and sometimes a great way up. Legume broad, 

 linear, compressed, 1 -celled. Seeds sometimes imbedded in 

 pulp, sometimes in farina, and sometimes, though rarely, en- 

 wrapped in a pellicle.- Usually unarmed trees or shrubs, with 

 spikes or heads of red or white flowers. This genus will require 

 to be still further divided into separate genera, when the charac- 

 ters of the species are better known. The legumes being in some 

 thickened at the margins, in others flat, straight, or twisted. The 

 seeds in some are imbedded in pulp, in others enveloped in a 

 dry pellicle at maturity. The stamens in some are monadel- 

 phous only at the base, while in others they are connected into 

 a long exserted column, and the pollen in the anthers in some is 

 powdery, but in others it is in a few granular masses, as in Ascle- 

 piadeee.

 nate. Leajlets large, from 2 to 9 pairs, the extreme ones always 

 the largest. The species contained in this division are all natives 

 of South America; they are unarmed trees, bearing spikes of 

 flowers, with a few exceptions, and furnished with glands on the 

 petioles between the pairs of leaflets. 



* Pterdpodae (from irTspov, pteron, a wing, and TTOUQ iroSoc, 

 pous podos, a foot ; in reference to the footstalks of the leaves 

 being winged). Common petiole evidently winged.
