236 CALYCIFLOBJB. 



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. CuRVEMEiMBRi^E, in which the radicle of the embryo is 

 bent back on the cotyledons. 



II. RECTEMEMBRI^E in which the radicle is straight. Of 

 each of these divisions two sub-orders are established. The 

 CuRVEMEMBRiiB are divided into, 1. PAPILIONACE^E ; and 2. 

 SWARTZI^SE ; and the RECTEMEMBRIJE into, 1. MIMOSE^E ; and 

 2. C.ESALPINE^E. 



DIVISION I. CURVEMEMBRIJS. 



Sub- Order 1. PAPILIONACE.E. 



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. Sophorece. 



Legume continuous. Stamens free. 



I. SOPHORA. 



Calyx 5-dentate, campanulate or sub-attenuated at 

 the base. Petals of the keel generally concrete at the 

 apex. Legume moniliform, apterous, many-seeded.
