RHODOREiB. 



[part I. 



The genus Clethra differs considerably from 

 the preceding genera, as the limb of the corolla 

 is so large and so deeply cleft, as to make the 

 flower appear to have five petals (see a in Jig, 

 6Q). There are ten 

 stamens, with broad 

 arrow-shaped anthers 

 (^), and a three-cleft 

 stigma, (c). The cap- 

 sule is dry, with three 

 many-seeded cells. In 

 C. alnifolia^ a native of 

 North America, (of 

 which^?^. 5 6 represents 

 a magnified flower,) 

 the flowers are erect, 

 and produced in a 

 spicate raceme ; but in C. arhorea^ a native of 

 Madeira, the racemes are panicled, and the 

 flowers drooping and somewhat bell- shaped. 

 Both species are very ornamental.

The plants included in this tribe are all con- 

 sidered to bear more or less resemblance to 

 the Rhododendron, though in some of them 

 the family likeness is not very strong ; and 

 the genera I shall describe to illustrate it are
