NolanaceEe. With the latter they agree in their separate ovaries, with the 
former in the structure of their embryos ; with both they disagree in the 
entirely apocarpous state of their cai'pels. If we attend to the embryo, they 
win stand among Convolvulacese ; if to the carpels, among Nolanacese : upon 
the whole, the latter must be accounted of the most importance, and conse- 
quently it is with Nolanaceee that I arrange them. Many more species of 
Nolana, than are described, are known, some of them shrubby ones ; but I do 
not find any characters that can be depended upon to form them into genera : 
in some species (N. prostrata) the carpels are combined by fours into 5 
nuculae ; in others they are aU separate (N. paradoxa) ; in others they are two 
solitary and simple and six combined in threes ; in others they are altogether 
irregular. 
Geography. Chile, Peru, and the Cape of Good Hope, are the principal 
stations of the species. Dichondra is found in most hot latitudes.

Essential Character. — Calyx inferior, persistent, 4-5-parted, with an imbricate 
sestivation. Corolla persistent, cut round at the base ; the limb regular, 4-5-cleft, imbricated 
in aestivation. Scales alternating with the segments of the corolla, and adhering to them, 
rarely wanting. Stamens equal to the segments of the corolla, and alternate with them ; 
anthers 2-celled, opening longitudinally. Ovary 2-celled ; ovules twin, collateral, erect ; 
styles 2, simple, sometimes connate. Capsule 2-celled, cut round at the base; cells 1-2- 
seeded. Seeds with a central fleshy albumen, and a spiral acotyledonous embryo. — Leaf- 
less, twining, parasitical herbs, with clustered 
Affinities. Similar motives which induced me to separate Cassythaceae 
from Lauracese have led me to divide this order from Convolvulaceae, with which 
its peculiar habits forbid us to confound it, and from which its technical cha- 
racters seem sufficient to separate it. 
Geography. Found aU over the world, occasionally, in cool, temperate, 
sub-humid climates.
