 Venezuela, Brazil, Peru, Tahiti, and Sandwich Islands. Subject to 

 considerable variation in its size, and also in the length of the point 

 of the leaf; in other respects quite uniform. Authentic specimens 

 of IT. Montagnei, Schimp. ; Meyenianum, Hampe ; Swinamense, D. ^ 

 M. ; apertum, SulUv. ; succosum, Mitten, show that they all belong 

 to the same species ; and to this list of synonymes it is highly prob- 

 able the following should also be added: H. rutilans, Brid. ; Pcep- 

 pigianwn, Hampe ; vesiculare, Schwaegr. ; suhdenticulatum and cono- 

 stegum, Mull.
