CALYCI FLOR/E. 
either straight or with the radicle bent upon the 
cotyledons. 
Trees, shrubs or herbaceous plants. Leaves generally bisti- 
pulated ; petiole very frequently callous at the base. This is a 
very extensive order, comprehending, according to the Prodomus 
of De Candolle, 3438 species. The properties they possess 
are various. I shall shortly allude to them in giving the general 
characters of the different sub-orders. 
This order is divided by De Candolle into ; 
I. CurvemembrIjE, in Avhich the radicle of the embryo is 
bent back on the cotyledons. 
II. RectemembrIjE in which the radicle is straight. Of 
each of these divisions two sub-orders are established. The 
CuRVEMEMBRiiE are divided into, 1. PapilionacEvE ; and 2. 
SwARTZiiE ; and the Rectemembri.® into, 1. Mimose®; and 
2. C®SALPINE®. 
Division I. CUR VEMEMBRUE. 
Sub-Order 1. Papilionace®. 
Character. Calycine lobes distinct. Stamens 
perigynous. Corolla papilionaceous. 
This sub-order may be further subdivided, into those, 1st, in 
which the cotyledons, when they appear above ground, become 
green, and assume the character of leaves ; and 2dly, those in 
which the cotyledons are thick and fleshy. It is deserving of 
remark that the seeds of none of the first subdivision are eaten 
by man or animals : whereas those of the second comprehend 
the different kinds of pulse, affording an important and whole- 
some description of food. 
* Papilionaceous plants, with the cotyledons leafy. 
Tribe I. Sophorew. 
Legume continuous. Stamens free. 
I. Sopiiora. 
Calyx 5-dentate, campanulate or sub-attenuated at 
the base. Petals of the keel generally concrete at the 
apex. Legume moniliform, apterous, many-seeded.
