3^6 FLOWERS OF GARDEN AND GREENHOUSE 



garden varieties, was introduced in 1740, and others came at intervals of 

 a few years, until in 1835 P. Brummondii, the popular annual, was intro- 

 duced from Texas. This has produced many variations from the original 

 purple-pink of its flowers, but, being an annual, these differences are not 

 dignified with garden names, as in the perennial species. In the latter 

 case such names are necessary, for the species have been so much crossed 

 and intercrossed that their parentage is exceedingly doubtful. Although 

 we give the characters of the principal species, we ought also to state 

 that the types are rarely cultivated ; their garden varieties and hybrids 

 being in greater request.
