of both species have five stamens, and two car- 

 pels, the styles of which are combined. The 

 leaves are simple, alternate, and without sti- 

 pules. Of the other plants contained in the 

 order, I may mention that Itea virginica is a 

 North American shrub, with white flowers; 

 and Anopteris glandulosa^ which is also a shrub 

 with white flowers, is a native of Van Diemen's 

 Land. 



ORDER XCYL— SAXIFRAGACEiE. 



The genus Saxifraga of Linnseus has been 

 divided so as to form several genera ; but they 

 do not appear to be generally adopted. The 

 flowers of all the species are rather small, and 

 they are generally racemose, or panicled ; and 

 the corolla consists of five spreading petals with 

 short claws, and there are twice that number of 

 stamens. Among the most common species 

 may be mentioned London Pride {Saxifraga or 

 Robertsonia umbrosa), and the Meadow Saxifrage 

 (Saxifraga or Leioggne graiiulaia), the flowers of 

 the latter being large, and produced singly. 

 In the genus Hydrangea the flowers are dis- 

 posed in corymbs, and they have five petals, 

 ten stamens, and from two to five styles ; but 

 in the outer flowers of the corymb the stamens 

 and pistil are often wanting.
