LINNdEAN ARTIFICIAL SYSTEM. 149 



stamens united into more than two parcels by their fila- 

 ments. (F. 191.) 



This collection of plants, has but little claim to the character of 

 a natural class. The genera which it contains belong to very 

 different natural orders. Thus, the genera theobroma, abroma, and 

 symplocos, belong to the Linnaean natural order i-olumniferrr. 

 Monsonia is referred to the order gruinales ; citrus to Mcornes. Hy- 

 pericum and ascyrnm belong to the order rotacece. Though one of 

 the smallest classes, it nevertheless furnishes many luxuries. 



117. Division: The orders of this class have long 

 been imperfectly defined, but Sir James Edward Smith, 

 has proposed the class should be divided into three 

 orders ; viz. dodecandria, icosandria, and polyandrm. 

 These are, of course, established on the number or in- 

 sertion of the stamens. 



118. Dodecandria: In this order the plants produce 

 flowers with stamens, or rather anthers, from twelve to 

 twenty or twenty-jive in number, their filaments uncon- 

 nected with the calyx. 



The orange, the lemon, and the theobroma or chocolate tree are, 

 according to Sir J. E. Smith, decidedly of this order. 



1 19. Icosandria : The plants of this order, have 

 flowers with numerous stamens, inserted, by means of 

 their filaments, in several parcels, into the calyx. 



Professor Willdenow has removed the genus melaleuca from the 

 next order to this; and Sir J. E. Smith has referred the orange, 

 lemon, &c. which have been previously arranged in this order, to 

 the order dodecandria as above.
