longitudinal slits confluent at the top, so as to represent a pore. Ovary l-celled, of 

 2 connate carpels, placentation parietal; style simple ; stigma obtuse ; ovules numerous,

The genus Itamondia, *which constitutes this little family, is represented by a Pyrenean plant 

 formerly referred to Vei-hascum (F. Myconi). It is distinguished from Solanece by its one-celled fruit, 

 its anatropous ovules and straight embryo; from Scroj^hularinece by its regular pentandrous flower and its 

 1-celled ovary ; and from GesTteracem by its regular isostemonous corolla and the placentiferous dehis- 

 cence of the capsule.
