3. QUAMOCLIDION Choisy ; DC. Prod. 13': 429. 1849 

 This genus was based on two species, of which the second was 

 referred doubtfully to the genus. The first had before been known 

 as a species oi Mirabilis, viz., -J/, triflora Benth. The type of the 

 genus Mirabilis L. is J/. Jalapa L. In the latter the filaments are 

 united at the base, the fruit is not viscid and the corolla is salver- 

 shaped with a long tube and broad limb. In Quamoclidion the 

 filaments are distinct, the fruit viscid and the corolla from nearly 

 cylindrical to bell-shaped but with a small limb. In Mirabilis the 

 flowers are solitary and in the typical species of Quanwilidion 3—6 

 in the involucre ; but as the number of flowers are not of value as 

 a generic character I have here included a species with one-flow- 

 ered involucres.
