It abounds near Carthagena, in New Spain ; and flowers in 

 August and September. 



15. Apocynum Nervosum; Nerve-leaved Dogs-bane. 

 Leaves ovate, nerved, cymes lateral; flowers yellow, large; 

 tube very long; stem shrubby, climbing. Flowers large, 

 bright yellow. Native of New Spain, near Carthagena. 



16. Apocynum Cordatum ; Heart-leaved Dog' s-bane. Leaves 

 oblong-cordate, pointed, sessile; flo wers lateral ; stem climb- 

 ing. This and the following species are natives of Vera 

 Cruz, in New Spain : they both have climbing stalks, by 

 which they mount the highest trees ; even in English hot- 

 houses they have risen upwards of twenty feet high. The 

 pods of these plants afford a cottony down, which is greatly 

 esteemed in France (where it is called Delawad) for stuff- 

 ing easy chairs, and making warm light quilts for persons 

 afflicted with the gout ; hence, in the south of France, where 

 it will thrive and produce seed in the open air, there are many 

 plantations of it, for the sake of the down. As these plants 

 are plentiful in the uncultivated parts of Jamaica, abundance 

 of the down might be procured from thence ; and if it were 

 only to become fashionable, would soon become vendible in 

 England. There they require no cultivation ; the only trouble 

 would be to collect the down, which on some of the large- 

 podded sorts is produced in great quantities. 



17. Apocynum Villosum ; Villose-jlowered Dog's-bane. 

 Leaves cordate, smooth ; flowers villose, lateral, on long 

 peduncles ; stem climbing. See the foregoing species.

 house or cape-stove, and may be increased by offsets from 

 the bulbs. The species are, 



1. Aponogeton Monostachyon ; Single-spiked Aponogeton. 

 Spike simple ; leaves cordate-oval, Common in fields that 

 are flooded for rice in the East Indies.

1. Aquilaria Ovata. Leaves alternate, ovate, mucronate. 

 T This is a large tree, the wood of which in its natural state 

 is white and inodorous : it has the name of lign-aloes, or wood 

 aloes, from its bitter taste. No part of this plant is poisonous ; 

 the aroma which it produces arises from a disease, caused by 

 oleaginous particles stagnating and concreting in the inner 

 parts of the trunk into a resin, which is extracted from the 

 wood when split. The perfume made of the wood is highly 

 esteemed by the Oriental nations. From its bark of the tree 

 the common writing paper of the Chinese is made. The 

 perfume is said to be good in vertigo and palsy ; the powder 

 restrains vomiting and alvine fluxes, by its astringent and 

 corroborating power. Three kinds of this wood are used 

 in the shops ; they are called Calumbac, Common Lign-aloes, 

 and Calambour. The first is the finest and most resinous ; 

 the last is almost a mere chip ; and the second a middling 

 kind. They all have the property of acting as cordials, and 

 strengthening the stomach, but in different degrees, and are 

 not much used.

 wardly, annexed inwardly to the receptacle, each produced

 mina : filamenta thirty to forty, subulate, the outer ones 

 shorter : anthers! oblong, erect, the height of the nectaries. 

 Pistil : germina five, ovate oblong, ending in subulate styles,
