- 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)."
Named in honor of Héctor Herrera an El Salvadorian scientist.
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.
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.
