The species is named for the Lacandona rainforest of Eastern Chiapas,
which is in turn named for the Lacandona Indians of Mayan descent.
Zamia lacandona is most similar to Z. cremnophila,
Z. standleyi, and Z. verschaffeltii (= Z. splendens
Schutzman and Z. katzeriana (Regel)Rettig). It differs from the
latter in having curved leaflets and from the former two in having
slightly but clearly obovate leaflets.
Distribution and habitat:
Endemic in Eastern Chiapas, Mexico where it grows in primary tropical
evergreen forest and also in disturbed areas of slash and burn
agriculture. It regenerates after clearing and burning along roadsides
and garden margins.
Apparently not threatened by local habitat destruction. Not yet listed
1997 IUCN Red List of Threatened Plants.
