stipe ; and the latter ovate fronds of the same length, 
but usually cordate at the base and upon long stipes. 
Lomaria zaniioicles of Gardner, a plant with a trunk 
four feet high, resembling a Zamia, found by Gardner 
in boggy places near the summit of the Organ Moun- 
tains, would also be a valuable addition to our small- 
growing Tree-ferns.* Brazil is rich in Tree-ferns, but 
only a few of them have as yet been introduced. I will 
mention only one or two. Dicksonia Selloiuiana, found 
onthe Organ Mountains, is,like the Lomaria above men- 
tioned, remarkable for its resemblance to an extreme 
southern species, dried specimens being scarcely dis- 
tinguishable from the Dicksonia antarctica, though 
most probably if the two were cultivated side by side 
they would prove very distinct. Cyatliea vestita and 
<7. Schamschin appear to be very plentiful throughout 
Brazil, and both are very fine species, the former 
having a trunk from twenty to thirty feet high. The 
two species of TricJiopteris — T. excelsa and T. elegans 
— are also very graceful trees, found in Southern 
Brazil, and although the latter is included in the fol- 
lowing enumeration, it is still very rare in our collec- 
tions. Several special localities in Brazil may be men- 
tioned as abounding: in Ferns, such as the Organ 
Mountains and St. Catherine’s, in the east; on the 
eastern slopes of the Andes, where at elevations of 
from fifteen hundred to four and five thousand feet, 
in some localities, they flourish in great luxuriance. 
At Tarrapota, in Peru, Dr. Spruce, in a diameter of 
fifty miles, collected no less than two hundred and 
* Fine plants of this Fern have been recently imported to this 
country by Mr. Low of the Clapton Nurseries.
