This appears to be found throughout ahiiost the whole or 

 South America, and in the southern States of North America 

 tooj if Roemer and Schultes are correct in considering H- 

 umhellata of Linn, as the same. It is indeed a very variable 

 species in the neighbourhood of Mendoza; the young um- 

 bels are sometimes simple, sometimes proliferous, each um- 

 bel sending out many rays, or often only a single ray, which 

 again becomes proliferous in the middle, and that repeatedly, 

 so that the rays have four or six whorls of flowers, as in the 

 H. trihotrys of Ruiz and Pavon.

The Bowlesia hhata of Ruiz and Pavon differs from this 

 in the shorter lobes of its leaves, which are undivided, m 

 the acute sinuses, in the greater length of its peduncle and 

 much larger size of the fruit. Stems procumbent.— Schlecht- 

 endal and Chamisso say tlie stem is erect, and yet « cubitaltSi
