THE NATURAL SYSTEM OF BOTANY.

In the previous articles we have given an account of nearly 

 all the orders of polypetalous exogenous plants ; that is, of 

 such exogenous plants as possess both calyx and corolla, with 

 distinct petals. These, it will be recollected, form the first 

 division of the »ub-class Angiospermae. The second division 

 of the same sub-class consists of those exogenous plants which 

 have both calyx and corolla, but whose petals are united. I n 

 this division there are thirty-five orders. It is impossible, 

 within our limits, to give more than a brief summary of them, 

 since we must, in our next and final article, conclude our ex- 

 planations of the Natural Orders for the present. 



Division II.— Monopetalous Exogenous Plants. 



Order — Caprifoliaceje. The Honeysuckle Tribe. 



To this order belong the Honeysuckles (Lonicera), the El- 

 der (Sambucus), Viburnum, Symphoricarpu3,^>r Snow-berry. 

 Nearly all are shrubs ; some, like the common Honeysuckle, 

 being climbers. They have opposite leaves, without stipules; 

 a tubular or rotate corolla, either regular or irregular ; stamens 

 usually as many as the lobes of the corolla ; fruit generally a 

 drupe ; seeds pendulous. They inhabit temperate regions, 

 and their properties are nauseous and bitter. The order is 

 sub-divided into Lonicerejs and Sambuce^j ; the former 

 having a tubular corolla, and filiform style; and the latter a 

 rotate or urn-shaped corolla. 



Order — RuBiACEiB. The Madder Tribe. 



This is a very extensive order, mostly confined to tropical 

 countries. It includes many plants of the most opposite as-
