are the same in number, l—o-ovulate. Ovules often descending, 
with superior and exterior micropyle. Fruit dry, crustaceous or 
coriaceous, sometimes with from 2-12 shells separating from the 
columella, or with septicidal cells. Seeds albuminous or exalbu- 
minous.— Woody or herbaceous plants, not bitter, not punctuate, with 
branches often articulate, leaves opposite, or alternate by abortion, 
accompanied by geminate stipules, almost constantly compound, 
2—-foliolate. Flowers generally drawn upon the axis, which bears 
them to the side of a leaf at a greater elevation.—(11 genera.) 
XII. Nirrariex.'—F lowers hermaphrodite, with cucullate petals, 
valvate-induplicate, with stamens double or triple in number to the 
petals ; ovary 2—6-celled, with a single descending ovule in each cell, 
superior and exterior micropyle. Fruit fleshy, with stone fluted or 
reticulated outwardly, 6-valved at apex, monospermous. Embryo 
fleshy, exalbuminous.—Shrubs from the salt plains of the temperate 
regions of the Old World, not bitter, not punctuate, with simple 
alternate leaves, and flowers in uniparous scorpioid cymes. — 
(1 genus.) 
XIII. Corrarteæ."—Flowers hermaphrodite or polygamous, with 
diplostemonous androceum, free carpels alternate with the petals 
when they are the same in number, with free styles. Ovules solitary, 
descending, with interior and superior micropyle. Fruit formed of 
5-10 shells, surrounded by accrescent petals, coriaceous or fleshy. 
Seeds exalbuminous, or with albumen reduced to a more or less hard 
membrane.—Shrubs, often sarmentose, with opposite or verticillate 
leaves, not punctuate, with axillary inflorescence.—(1 genus.) 
XIV. Surranex.i—Flowers hermaphrodite, with diplostemonous 
androceum, free, oppositipetalous carpels, and gynobasic free styles. 
Ovules geminate in each ovary, descending, with superior and 
exterior micropyle. Fruit formed of free drupes, surrounded by 
the persistent calyx, with thin mesocarp, and solitary ascending 
seed. ÆEmbryo exalbuminous, folded upon itself, with superior and
