Upwards of 600 species of this genus have been described ; many of them, however, 
are imperfectly known, and it is probable that with fuller materials a, considerable 
reduction of this number would be made. Some of them are tall herbs, and others are 
trees; but most of them are shrubs, some of them of climbing habit.
