Tlic plant is doublless a liyl)rid Ijclween llieso two species, as is sliown by 

 ils inlermediale charafter. and also by Ihe facl Ihal il is self-lerlile, and fertile 

 willi tlie pollen of either of Ihe parent species. A delailed description of Ihe 

 parent species, and of the hybrid, are given by the author, the following points 

 being of interest : 



A certain numlier of the chief characters of Ihe hybrid are intermediale 

 bchveen Ihose of the parent species. Such a characler is Ihe height of the 

 flowering stems, which in C. pyramidalis are 1 m. .50-2 m. in C. verskotor 

 Ûm. .jO-0 m. 75, and in the hybrid 1 m.-l m. 2,"). Again, in C. versicolor the slem 

 leaves are few in number, at the base of the inflorescence, in C. pyramidalis; 

 Ihey allain the summit of the inllorescence, and in the hybrid they ascend half 

 way up the inflorescence. A constant characler of C. versicolor is the ring of 

 dark blue or violet at Ihe base of Ihe pelais; this is completely absent in 

 C. pyramidalis and in the hybrid il is less niarked than in C. versicolor. 



Olher intermediale characters are the Ihickness of the pelais, and liic 

 number of flowers in each group on the inflorescence. 



Certain characters of the hybrid are much nearer the corresponding cha- 

 racters of one orolhei' of the parents. Such are the glandular tecth ^vhi<■h are 

 found on the leaves of C. pyramidalis. Another paternal characler found in 

 Ihe hybrid is Ihe duration of Ihe flowering period. 



Finally, in the hybrid are found certain features which do not exist in 

 either parent. Among thèse are the lenglh of the pétioles, and the length of 

 the floral pedicels, both of which are longer than in either parent.
