ALLIANCE in. UMBELLALES. 
Essential Character. — Flowers usually disposed in umbels. Calyx superior. Disk 
epigynous, very thick, in two or more pieces. Carpels always one-seeded. Stems usually 
hollow. 
ITie only other albuminous alliance with a superior calyx is the Grossal, 
and that is readily known by its solid stems, and flowers never being arranged 
in regular umbels, while there is generally more seeds than one, usually many, 
in each carpel. The leaves too of this alhance are almost always dilated, and 
sheathing at the base, as in Ranunculaceae. The motives which induced me 
to place Myristicacese in the same alliance as Anonaceae have led me to group 
Umbelliferse in the vicinity of Ranunculacese, contrary to the opinion and prac- 
tice of the greatest of our living authorities. If we consider fairly the respec- 
tive organization of Ranunculacese and UmbeUiferae, especially of such genera 
as Thalictrum in the one, and Pimpinella in the other, we shall find that no 
positive mark of discrimination between them can be pointed out except the 
superior carpels of the former, and the inferior ones of the latter ; for the in- 
definite stamens of Ranunculaceae are no longer capable of furnishing a dis- 
tinctive character since the discovery of Casalea. As for Thalictrum foenicu- 
laceum, any one would take it for an Umbelliferous plant, without attentive 
observation. Now it is impossible to acknowledge any system to be natural 
in which, under these circumstances of almost identity in structure and in sen- 
sible properties, two such orders are disjoined ; and I consider the restoration 
of UmbeUiferae and Ranunculacese to their true relative positions, one of the 
strongest arguments in favour of the necessity for this albuminous group. 
On the other hand, Umbelliferae are but little difibrent from Vitaceae, except 
in their superior calyx and pendulous ovules ; for Aralia racemosa has quite as 
much the appearance ' of a Cissus, and its structure also, except in those re- 
spects, as it has of a plant of the Umbellal alliance.

Essential Character. — Calyx superior, either entire or 5-toothed. Petals 5, 
inserted on the outside of a fleshy epigynous disk ; usually indexed at the point; aesti- 
vation imbricate, rarely valvate. Stamens 5, alternate with the petals, incurved in aestiva- 
tion. Ovary inferior, 2-celled, with solitary pendulous ovules; crowned by a double fleshy
