DELPHINIUM Grandiflorum. ' 

 Great/lowered Larkspur. 



Class and 0/Y/er.— Polvandria Trigynia. 

 Syn. Delphinium Grandiflorum. Curt. Bot. Mag. pi. 1686. 



Root fibrous,— stem erect, much branched,— radical leaves on long naked peti- 

 oles, multipartite, segments narrow acute,— cauline leaves sessile, ver- 

 ticillate, linear acute, on the lateral branches, generally single,— lower 

 flowers on very long peduncles— calyx none —corolla very brilliant blue 

 —outer petals five, ovate, undulate, upper one terminated by a long 

 rugose spur— nectaries two, divided into four segments, the two lower 

 ones marked with a bright bearded yellow spot, enclosing the parts of 

 fructification— stamens numerous— styles three— capsules three celled. 



The o-enus Delphinium is a beautiful and showy one, and con- 

 tains almost innumerable varieties, none, however, can exceed in 

 beauty of colour the species figured, which is a native of Siberia, and 

 was introduced into this country about the year 1741. It is a hardy 

 plant, of the easiest culture, not requiring any particular treatment, 

 thouo-h it o-rows best in a rich brown loam — if allowed to sow its seed, 

 a number of young plants will soon appear, which will flower the next 

 year ; this mode, however, of propagating it, is by no means certain, 

 and therefore, in order to obtain it true, it is better to divide the roots, 

 which may be done in spring ; numerous and very beautiful varieties 

 are constantly raised fiom seed. Amongst the most desirable distinct 

 species are 



D. Aconiti. pallidum. 



— cheilanthum. pictum. 



— macranthon. Menziesii. 



— alpinum. montanum. 



— azureum. ucranicum.
