There cannot be the smallest doubt of this being the L. acu- 
tangulus of Ruiz and Pavon. The figure is excellent, save that the 
large fruit, apparently belonging to L. revolutus of the same writers 
is added gratuitously. Those authors found the L. acutangulus 
in Chinchoa of Peru, in mountain districts; Mathews gathered it 
at Casapo (n. 2096); Humboldt and Bonpland m J^ew Grenada, 
between Maraquita and Santanna; Moritz at Menda and in 
the province of Truxillo; Piirdie on the Sierra Nivada, Sierra 
SEPTEMBER IST, 1847.
