 litica, Moc. et Sesse, fl. mex. icon. ined. This plant is said to 

 possess powerful antisyphilitic properties; its expressed juice, 

 taken in doses of 4 ounces, excites violent perspiration and secre- 

 tion of urine, and is said to cure venereal disorders in an incredi- 

 bly short space of time. 



Syphilitic Heimia. Shrub 4 to 6 feet. 



Cult. The species of Heimia are very pretty shrubs when in 

 flower ; they only require to be sheltered from frost in winter ; 

 this may be done by mats, if the plants are planted against a 

 south wall in the open ground ; and if in pots they'should be 

 placed in the greenhouse. Cuttings of them strike readily either 

 in sand or mould under a hand-glass.
