- Zamia montana A. Braun, "Monatsber. Königl. Preuss. Akad. Wiss. Berlin, Apr 1875 : 376" (1875).
- "TYPE: Colombia, Antioquia, 1750m, Zarucchi et al. 5724 (neo NY; isoneo MO, fide Stevenson, Fl. Colombia)."
Etymology: In reference to the submontane to montane habitat
of the species.
Zamia montana was described in 1875 by Alexander Braun (one of
the most famous, eclectic German botanists of the 19th century)
from material collected in by Gustav Wallis in Colombia. The species
was collected once again in 1888 by Kalbreyer and then not seen again
for 100 years. Both the Wallis and Kalbreyer collections were lost and
no type specimen was extant resulting in some doubt about the existence
of the species until its recent rediscovery in 1980's.
Zamia montana is readily identified by its obviously long
obovate leaflets with shallow grooves between the veins of the upper surface.
Distribution and habitat:
Zamia montana is endemic to the submontane and montane areas
of Antioquia, Colombia where it grows from 1800-2000 m in wet montane
forest. Z. montana grows at highest elevation known for any
neotropical cycad and is known only from collections at and near the
Conservation status: Zamia montana is extremely rare and is
unknown in cultivation. Its habitat is also extremely threatened by
logging activities. In fact, it may well be extinct in the wild because
the only known population occurs in an area that was recently logged.
