Zamia herrerae

Zamia herrerae Calderón & Standl., "Proc. Wash. Acad. Sci. 14(4): 93-99, fig. 1" (1924).
"TYPE: Salvador, vicinity of Sonsonate, 17 Jul 1923, S. Calderon 1682 (holo US)."


Etymology: Named in honor of Héctor Herrera an El Salvadorian scientist.

Historical notes:

Distinguishing features: Marginal teeth of the leaflets distant and well developed. Leaflets are most similar to Z. standleyi but the cones, in particular the seed cones, are quite different from Z. standleyi and those of Z. herrerae lack the apical "hook" of the former.

Distribution and habitat: Known from El Salvador and more recently Honduras, Guatemala and neighboring Chiapas, Mexico and Nicaragua. Zamia herrerae grows in primary and secondary forest from 200-800 m and does best as an understory plant in pine-oak forest and well drained sites in cloud forest and mesic situations.

Conservation status: Not well known from the wild or in cultivation most likely because the areas it is from have not been well collected botanically. However, given recent botanical activities in these areas and the paucity of collections of Z. herrerae would indicate that it is quite rare and thus easily endangered in the wild. 1997 IUCN Red List of Threatened Plants Category R,II,E.

Description:

Stems subterranean and tuberous, 3-10 cm in diameter.

Cataphylls from 1-2 cm long, sheathing at first, with a pair of inconspicuous stipules.
