- Zamia soconuscensis "Schutzman, Vovides & Dehgan", Bot. Gaz. 149(3): 347-351 (1988).
- "TYPE: Mexico, Chiapas, Feb 1939, Matuda 2659 (holo F iso MICH CR)."
Named for the geographic area, Sierra del Soconusco (Sierra Madre de
Chiapas), in which it is found.
Linear-lanceolate leaflet with entire margins and an attenuate apices.
Leaflets often adaxially concave. Zamia soconuscensis is in
many ways similar to Z. inermis. Zamia inermis has
smooth petioles and erect leaves with very coriaceous leaflets with
short acute apices. In contrast, Z. soconuscensis has
prickled petioles and spreading to recurved leaves with mildly
coriaceous leaflets with long acute to attenuate apices.
Distribution and habitat:
Found as an understory plant from 500-1000 m growing on organic
clay soils in evergreen forest to cloud forest.
The species appears to be threatened in habitat as a result of
clearing for agricultural purposes. However, the efforts of
Andrew Vovides to establish nurseries for endemic plants, including
cycads are proceeding successfully, so that wild collecting is
minimized, propagated material is entering the horticultural
market. and habitat is being conserved to some extent.
