small and irregularly formed ; sometimes they are rolled inwards, and 
much twisted, with a few imperfect stamens intermixed among them. 
The size of the outer petals is remarkable, many of them being about 
an inch and a half in diameter, and some will be found even larger. 
They are very prettily marked with dark-coloured veins, and altogether 
form as elegant a flower as any which we have yet represented.
