into one body or cylinder, through which the pistil 

 passes. (F. 189.) 



The class monadelphia upon the whole, is a natural class, the 

 greater number of the genera of which, are arranged by Linnaeus in 

 his natural order columnifercc. 



101. Division : The orders of this class, are neither 

 founded on the pistil nor on the seed-vessel, but upon 

 the number of the stamens. They are eight in number, 

 and are called after the classes, triandria, pentandria, 

 keptandria, octandria, decandria, endecandria, dodecan- 

 dria and polyandria, according to the number of stamens 

 in each flower. 



In all the preceding classes we have observed, that the stamens, 

 whether few or many, have been evidently distinct from each other ; 

 lut in the present case, you will always find them united at the 

 bottom, though perfectly separate at the top, by which their number 

 is very readily ascertained^ 



102. Triandria: Including such plants of the class, 

 as produce flowers with three stamens. 



Here is arranged the genus tamarind, consisting of only one 

 species The ferraria whose fugitive Howers scarcely last one fore- 

 noon, and galaxia, whose beauty is almost as transient, are likewise 

 found here. In this order also, is the pretty genus sisyrinchiutn, 

 and the singular Cape plant aphyteia, consisting of a large flower 

 and succulent fruit springing immediately from the root, without 

 stem or leaves. 



103. Pentandria : In this order of the class, we have 

 such plants as produce flowers vfltitfive stamens. 



The genus erodium or heron's-bill, which of late has been sepa- 

 rated from that of geranium, hennannia a pretty Cape genus, and a 

 fe\v others constitute this division. Sir J. E. Smith refers the family
