native of Brazil, presented to our garden by Messrs. Henderson.

which he found growing in rocky places about Rio Janeiro. [i 
is quite different from Billbergia pyramidalis, and every other 
with which we are acquainted. Our readers will observe, that, 
though the leaves grow erect, or nearly so, on the living plant, 
our figure of the leaf represents it bent back, to enable us te 
bring an entire one into the plate. It requires the heat of the 
stove, and flowered with us in November of the present year,
