upper leaf-axil, and successively from lower ones; spadices

the peduncle of the spadix. Fruit globose-obovoid. Leaves

A, Bonnetii and A. Listeri are rare in cultivation. 
ARGEMONE. Mexican Poppy. Syn. Echtrus. This 
genus includes about half-a-dozen species, all American, 
one being broadly scattered over the tropical regions of 
the globe. To the information given on p. 110., Vol. I., 
the following should be added:

third Duke of Argyll, who introduced many American 
trees and shrubs into this country). Syn. Oxymitus. 
Orv. Bignoniacee. A genus embracing about ten species 
of perennial herbs, confined to the Andean region 
of Chili and Pern. Flowers yellow, purple, or pink, 
variously disposed; calyx five-parted, the segments 
narrow; corolla-tube long, enlarged above, straight or 
ineurved, the limb spreading, with five nearly equal lobes, 
or the two posterior ones smaller; stamens four, affixed 
to the middle of the tube. Leaves radical or alternate, 
digitately five- to seven- (rarely three-) foliolate ; leaflets 
incised-toothed or twice or thrice pinnatisect. Only one 
species calls for mention here. It requires sandy, well- 
drained soil, and an intermediate temperature.

the inner ones much narrower; corolla funnel-shaped, the 
limb plicate, angled, or five-lobed ; stamens included ; cymes 
often few-flowered, pedunculate in the axils, or the
