Allgemeine Informationen:
Eremospatha laurentii is found in both open areas as well as in closed-canopy forest. However, this species responds particularly well to selective logging and is a common component of regrowth vegetation where it occurs.


Heimisch in, Cameroon, Congo, Equatorial Guinea, Gabon, Liberia, Nigeria, Sierra Leone, Democratic Republic of the Congo

This species occurs predominantly in the lowland forests of the northern Congo Basin. However, intriguingly, there are outliers of this species found in the forests of Upper Guinea, with a pronounced disjunction from Ivory Coast to Benin.
