of the stamens, and especially in the structure of the ovary and fruit. In these 
respects Aquifoliacese are found by Brongniart to agree so completely with 
Ebenaceie, that that order does not, in fact, differ essentially from Aquifoliacese, 
except in characters of a secondary order, such as the calyx and corolla less 
deeply divided, the stamens often double the number of the segments of the 
corolla, the style being sometimes divided, the cells of the ovary usually con- 
taining 2 collateral ovula, and, finally, in the cells of the fruit not becoming 
bony, as in most Aquifoliacese. Von Martins places them near Polygalaceoe. 
Geography. Found in various parts of the world, especially in the West 
Indies, South America, and the Cape of Good Hope. Several are found in 
North America; but 1, the common Holly, in Europe. 
Properties. The bark and berries of Prinos verticillatus possess, in an 
eminent degree, the properties of vegetable, astringent, and tonic medicines, 
along with antiseptic powers which are highly spoken of by American prac- 
titioners. Barton, 1. 208. Prinos glaber and Ilex Paraguensis are used as 
tea : the latter yields the famous beverage called Mate in Brazil. Myginda 
Gongonha is diuretic. DC.

Alliance IV. NOLANALES. 
Essential Character. — Fruit divided into distinct lobes. 
Order CLXXIV. NOLANACEiE. 
Nolanace.®, Lindl. Nixus PL 18. (1833) ; Martins Conspectus, No. 119. (1835). — 
CoNvoLVULACEiE § Dichondreae, Choisy (1834). 
Essential Character. — Calyx 5-parted, regular or irregular. Corolla monopetalous, 
with a plaited aestivation, usually thickened in the tube. Stamens 5, equal, inserted into 
the tube, alternate with the segments of the corolla ; anthers oblong, 2-celled, bursting 
longitudinally. Pistil composed of several carpels, either distinct with distinct styles, or 
distinct with a single style, or partially combined into several sets with a single style seated 
on a succulent disk. Stigma somewhat capitate. Fruit enclosed in the permanent calyx, 
constructed like the pistil ; pericarp woody, and a little succulent or membranous. Seeds 
ascending, solitary ; embryo curved, w’ith either straight or doubled cotyledons, in the 
midst of a small quantity of albumen ; radicle next the hilum. — Prostrate or erect, her- 
baceous or suffruticose plants. Leaves alternate, without stipules. Flowers usually showy. 
Affinities. The genus Nolana, sometimes referred to Boraginaceae, 
sometimes to Convolvulaceae, has been erected into a distinct order, on account, 
on the one hand, of < its regular plaited corolla, and, on the other, of its 
separate carpels. It appears to approach far more nearly to the latter than 
the former, differing, in reality, in nothing excepting its separate carpels, that 
is to say, much as Boraginacese from Toumefortiaceae, or Labiates from 
Verbenaceae, 8cc, The only difficulty in this character consists in knowing 
whether the genera Falkia or Dichondra belong to Convolwilaceae or to
