* I omit SchistantJie, Kze. (DC. 1. c. p. 251), as probably founded in 

 error ; it is thus cliaracterized :— " Calyx 5-parted, unequal. Corolla re- 

 supinate, the limb expanded, 5-fid, the back (apparently front) lobes sepa- 

 rate even to the base of the corolla, tlie throat under the anteal lip 2- 

 saccate. Capsules ovate, obtuse, emarginate, septicidal." Said to resemble 

 Alonzoa incisifolia ; possibly only a monstrous state of that common gar- 

 den plant.
