We received a specimen of this rare plant in August 

 last from Mr. Blair, gardener to Miss Martineau, as a native 

 of Mexico. Upon comparing it, however, with the figure of 

 Phijsianthus albens, given by von Martins from specimens 

 collected by him in the woods of Ypanema in the Province 

 of St. Pauls, and with the plate in the Botanical Magazine 

 of the same plant from Buenos Ayres, we are obliged to con- 

 clude either that there has been some mistake with regard 



Liteiallv bladder-flower, in allusion to the inflated corolla.
