NATURAL ARRANGEMENT. 
of the suborders will not be found in the body of the work. M. Decandolle's method, however, being here 
adopted, it will be useful to explain the principles upon which it is founded. He divides LeguminosEe into two 
grand divisions, the first of which consists of plants, the radicle of whose seed is curved back upon the edge of 
the cotyledons, and the second of those whose radicle and cotyledons are straight : the former are Curvem- 
BRiiE, the latter RectembrijE. In the Curvembrics, certain diversities in the structure of the calyx and corolla 
again divide into two principal forms, one of which, comprehending all the genera with papilionaceous flowers, 
is called Papilionacese, and the other, consisting of a very small number of species, with one or two petals or 
more, and an obscurely lobed calyx, is called Swartzieas. The last is not subdivided, but the Papilionaceae 
resolve themselves into the two great tribes pointed out by M. Decandolle, namely, those with fleshy cotyle- 
dons and eatable pulse, Sarcolobce, and those with foliaceous cotyledons and seeds which are not eatable, 
Phyllolobce. Each of these is divisible by three, upon slight differences in the fructification. In Rectembrice 
two suborders, Mimoseae and Ceesalpines, are formed upon variations in the asstivation of the calyx and 
corolla; in the former, it is valvate, in the latter, imbricated; the first constitute a single tribe, the latter 
divide into three, distinguished by less momentous peculiarities of structure. Having premised thus much, 
the following tabular explanation will be intelligible :
