On a Supposed New Species of Ceratozamia. 113 
drical and flexuose! Again, in the description of the leaves it is 
stated, “folia patentissime, apicem versus graciliter recurvata,’ 
1-2 metres long. ° The leaves of our plant are much recurved 
towards the apex, and are three metres long, or more. The leaflets 
are described as being from “22-35 c. m. longa, utrinque lete 
viridia.” Now, this last observation is quite at variance with the 
colour of the leaflets of our plant, which are fuscous brown on 
their under sides, and dull green on the upper sides. 
De Candolle, in his Prodromus (vol. 16, p. 547), describes the 
leaves of C. longifolia as being “ circa 35 pedalia, foliolis utrinque 
15-16, pedalibus vel paulo longioribus, pollice paulo latioribus 
instructa.” The leaves of our plant are 8-10 feet long, with 
30-40 pairs of leaflets. 
Finding that the plant on the table disagrees so materially in 
these instances from the descriptions of Regel and De Candolle, 
I incline to think it may prove to be a distinct species from C. 
longifolia (Miquel) ; and if so, I propose to name it, ora 
Ceratozamia fusca-vridis. 
The following description is applicable to it, viz. :— 
Trunk globose, dark brown, more or less clothed with fuscous 
hairs and the bases of old leaves, dividing occasionally from apex 
to base into secondary trunks; bases of the leaves broadly ovate, 
and adhering closely to the trunk, mixed with perules, ovate at 
the base, tapering gradually from base to apex into a sharp point, 
which is slightly reflexed and spreading, clothed with silky fuscous 
down. Leaves rather slender, erect at first, ultimately spreading 
and recurved at their points; from eight to ten feet long. Petiole 
roundish, clothed with dark fuscous pubescense, and beset with 
numerous short, sharp, strong prickles, more especially near the 
base; rachis, with two rather deep channels, one on each side of 
the upper surface, and more or less covered with scattered prickles. 
Leaflets alternate or opposite, sessile, with slightly decurrent bases 
at point of attachment—from thirty to forty pairs, eight to ten 
inches long, two-thirds of an inch wide in the central portion, 
where the margins are slightly raised, entire, fuscous on the under 
side, dull green on the upper side, subfalcate, tapering to a sharp 
point, which is slightly reflexed, nerved with eighteen to twenty 
obscure nerves. Female cones on brown scurfy stalks, two or
