In our judgment the present plant can be regarded 
only as a variety of the species of this name. It expands 
its flowers like the other plants of that in the evening, and 
has all their features, except in as far as regards the colour 
of the corolla, the smaller size of the parts (where however 
the same proportions are preserved), a calyx in which the 
leaflets can scarcely be said to be either so far or so slenderly 
prolonged as to be called awned, as they are in the other, 
and the shortness of the floral organs, which do not emerge.
