The flowers of this hybrid seem to be intermediate between the 
two parents. The calyx is of the general shape of that of M. 
puniceus whereas the corolla is similar to that of M. longiflorus, 
except in regard to color. The amount of hairiness varies, but 
in general it is intermediate between the two parents. 
It is probable that the plants of the two other groups are also 
of hybrid origin, but further experimental work will have to be 
done to determine their éxact status. Until such studies are 
made, it seems advisable to give the members of these two 
groups varietal names.
