 For fear that this purely arti6cial key may not be fouDd 

 to apply with all garden plants, which are "so much more 

 liable to variation, there is given below a key based on 

 more technical characters, derived from Gray's Synop- 

 tical Flora: 



botaxist's key. 



1. Section Euthacelia. Ovules 4, a pair to each 

 placenta; seeds generally fewer, with reticulate or pit- 

 ted testa: corolla-tube with 10 laminate appendages in 

 pairs at the base of the stamens.
