and variety, by the production of seed-bearing mules. It is 

 supposed by several of the best-informed botanists, that 

 many of what we call species have been so originated by 

 nature in the heathery surfaces of the Cape ; and it is cer- 

 tain that a number have been so produced in the green- 

 houses about London. From these, as given in the Cata- 

 logues of Lee, Andrews, Cormack, Page, Donn, Sweet, 

 and others, we might have greatly increased our list ; but 

 we prefer a selection, and have rejected some names be- 

 cause the plants no longer exist ; others, because we consi- 

 der them as only varieties ; and some, as not to be pur- 

 chased at the public nurseries.
