374. V. bracteosa x iiastata. In a pasture 1 mile W. of Mead, 

 Saunders Co., in June, 1890, there were found a few specimens 

 of a Verbena, which undoubtedly is a hybrid between V. bracteosa 

 Michx. and V. hastata L. The specimens are of the size and gen- 

 eral appearance of V. hastata, but branched from the base and 

 ascending. The leaves are of the size of those of V. hastata but 

 more divided like those of V. bracteosa. The bracts are like those 

 of the latter. Dr. Engelmann mentions several Verbena hybrids 

 but not this (Rydbergj.
