A neat little greenhouse plant, native of swamps near 

 Port Jackson, and in Van Diemen's Land. It should be 

 cultivated in peat earth, and planted in a pot which can be 

 immersed in a tank of water, when it will flower daily for 

 five or six weeks in the middle of summer, opening its 

 blossoms at sunrise, and closing them before noon. 



Dr. Brown suggests its being too nearly related to 



* So called after Mons. Villars, the author of a History of the Plants of 

 Dauphine.
