Notes:
Janotia is similar to Breonia, and has been confused with that; for their separation, see the key to Breonia and similar genera on the page for that genus. Janotia is characterized by its relatively large, persistent, lingulate or obovate stipules, its relatively large leaves, and its axillary inflorescences with each peduncle bearing a single globose head. Ridsdale (1975: p. 550-551) presented morphological descriptions of this genus and of J. macrostipula. Razafimandimbison & Bremer (2001) presented an analysis based on molecular sequence data of the relationships of Janotia, which they found grouped with Gyrostipula and Breonia, and these all related to Breonadia. Janotia has apparently been documented by very few specimens.
