 are more conspicuous than the rest. Above the leaves 

 are smooth and of a rich shining green ; beneath they are 

 rather paler, and covered with brownish, short pubescence, 

 the edges being frin'ged, tr ciliated, with the same. Flowers

 a little towards the base, and of a bright reddish purple.

 smell, like that of an over-ripe melon.
