Sherard. Flowers the size and colour of the preced- 
ing. While writing the genus Gerardia, I strongly 
suspected G. cassioides to be a distinct genus, which al- 
ready had been considered so by Walter and Gmelin. 
Havingnomaterialsthen at hand, I followed the authority 
of Michaux. But finding in the Sherardian Herbarium 
not only that species, but also a new one described 
here, I was convinced of its generic distinction, the 
character of which is well expressed \i\ Walt . fi. car.iyi. 
I have named this genus in memory of the late Henry 
Seymer, Esq. of Hanford, Dorsetshire, a gentleman 
much celebrated for his extensive collections in natural 
history, and for whom Dr» Solander had so great a re- 
gard as to dedicate the plant which afterwards was 
called Solandra grandifLora to his memory, as I have 
seen it named Seymera in the Herbarium of A. B. Lam- 
bert, Esq., in Dr. Solander’s own handwriting.
