Zamia urep may be distinguished by the combination of symmetrical
almost perfect elliptic to broadly lanceolate leaflets with sharply serrated
margins and acuminate apices and unarmed petioles and rachis. In general
appearance, Zamia urep is most similar to Z. obliqua
and indeed looks like a smaller version of the latter. It differs
from Z. obliqua in being a smaller plant with subterranean,
lacking prickles on the petiole and rachis, and have more prominently
toothed leaflet margins. Also, the cones are much smaller and with
Distribution and habitat:
Zamia urep is known from only five collections from three
nearby localities even though over the past 50 years many expeditions
have collected in the area where it is found. Thus, it is assumed
that the species is quite rare. Not yet listed in the
1997 IUCN Red List of Threatened Plants.
Stem subterranean, to 20 cm long, 2.5-5 cm diam.
Cataphylls narrowly lanceolate, 3-4 cm long, 5-8 mm wide.
Leaves 1-4, 40-70 m long; petiole smooth, 20-40 (48) cm
long, canaliculate adaxially at the base and flat distally; rachis
without prickles, 8-15 cm long, 2-5 pairs of leaflets.
Leaflets broadly lanceolate to elliptic, corieacous, obliquely
cuneate basally, acuminate apically, margins sharply serrulate in upper
third, the median ones 10-20 cm long, 3-6 cm wide.
Pollen cones 1-2, tan to light brown, cylindrical, 3-6 cm long,
0.6-1 cm diam.; peduncle 18-22 cm long, 2-3 mm diam.; microsporophylls
with sterile tip composed of six steeply inclined facets surrounding
a centrally depressed terminal facet, sporangia present on both the
adaxial and abaxial surfaces of the fertile region.
Seed cones tan to light brown, cylindrical to ovoid-cylindrical,
3.5-5 cm long, 1.5-2.5 cm diam; peduncle 13-16 cm long, 3-5 mm diam.
