438 FOREST CULTURE AND 
Wettinia Maynensis, Spruce. —Cordilleras of Peru. 
Like the foregoing, it attains a height of 40 feet, and 
advances to elevations of 3,000 feet or 4,000 feet. 
Before finally parting from the American palms it 
may be appropriate to allude briefly to some of the 
hardier kinds, which were left unnoticed in the course 
of this compilation. From Dr. Spruce’s important 
essay on the palms of the Amazon River may be 
learned that, besides other species as yet imperfectly 
known from the sources of this great river, the fol- 
lowing kinds are comparatively hardy; thus they 
might find places for cultivation, or even naturaliza- 
tion, within the limits of our colony: Geonema un- 
data, Klotzsch ; Iriartea deltoidea, R. and P.; Iriartea 
ventricosa, Mart., which latter rises in its magnifi- 
cence to fully 100 feet; Iriartea exorrhiza, Mart.; 
this, with the two other Iriarteas, ascends the Andes 
to 5,000 feet. Qsnocarpus multicaulis, Spruce, ascends 
to 4,000 feet; from 6 to 10 stems are developed from 
the same root, each from 15 to 80 feethigh. Euterpe ; 
of this two species occur in a zone between 3,000 feet 
and 6,000 feet.—Phytelephas microcarpa, R. and P.; 
eastern slope of the Peru Andes, ascending to 3,000 
feet. Phytelephas macrocarpa, R. and P.; also on 
the eastern side of the Andes, up to 4,000 feet; it 
is this superb species which yields by its seeds part 
of the vegetable ivory. Phytelephas equatorialis, 
Spruce ; on the west slope of the Peruvian Andes, up 
to 5,000 feet ; this palm is one of the grandest objects 
in the whole vegetable creation, its leaves attaining a 
length of 80 feet! The stem rises to 20 feet. Palm- 
ivory is also largely secured from this plant. Though 
requinoctial it lives only in the milder regions of the
