SOUTH AMERICAN PLANTS. 33 
24 in. broad, and are angularly sinuate. Numerous flowers 
are crowded together in a fascicle on one side of each axil, the 
peduncles being 9 lin. long, with a glabrous, spathulate bract, 
at the base of each, from 2 to 9 lin. long. The calyx is 
deeply cleft into 5 acuminate, subulate, membranaceous, 
green segments, pilose, 2 lin. long. The corolla is of a dusky 
green, less than half the size of that of the former species, 
sparsely covered with long, soft pubescence, broadly campanu- 
late, submembranaceous, veined, and deeply divided into 5 
ovate, acute lobes, with undulated margins, and terminated 
by a woolly rostrate apex; the stamens are included; the 
filaments, entirely free, slender, glabrous, erect, and re- 
curved at the summit, arise from the points of a slender, 
adnate, 5-toothed ring in the base of the corolla; the anthers 
are ovate, cordate, 2-lobed. The ovarium is round and smooth ; 
the style short and thick; the stigma clavate, broad, and 2- 
lobed. 
PIoNANDRA. 
Under this name I propose to found a genus comprising 
some Solanaceous small trees and arborescent shrubs with 
wide spreading branches, and long racemes of flowers 
similar to three species that I found in the Organ Mountains 
in 1829 and 1838. The Witheringia diploconos,* figured by 
Von Martius in his Nov. Gen. et Sp. vol. 111. p. 76, tab. 229, 
evidently belongs to this genus, the characters of which may 
be thus defined. 
* The genus Witheringia, according to the latest arrangement in the 
Repert. Bot. of Walpers, 3.29, contains many (24) heterogeneous species, 
and it appears to me that very few of those enumerated, harmonize with 
the generic character as established by L’Heritier. In the herbarium of 
Sir William Hooker, I can find no plant. corresponding with the typical 
in the British Museum where L’Heritier’s original specimens 
there are two plants marked Witheringia solanacea, both 
the figure and description of the founder 
of the genus. In the absence, therefore, of the typical plant, without any 
good description of it, or any satisfactory, drawing of its details, without 
even the knowledge of the country where the original was obtained, nor 
by whom collected, it is difficult to understand the true limits of the genus.
