Assessor/s:

Taylor, A.

Reviewer/s:

Donaldson, J.S. & Bösenberg, J.D.

Justification:
Qualifies for an Endangered status based on estimated decline over the past three generations (>50%), restricted distribution (extent of occurrence = 6,250 km²) and small population size of ca. 500 mature individuals and continuing decline.

History:

2003	–	Endangered (IUCN 2003)
1997	–	Rare (Walter and Gillett 1998)

Population [top]

Population:	The population status of Z. skinneri is affected by some confusion regarding the circumscription of this taxon. Currently several populations from the region of the Panama canal to the Costa Rican border could be regarded as Z. skinneri. At present, populations with green emergent leaves from the Bocas del Toro province in NW Panama region appear to be true Z. skinneri and that plants with red emergent leaves in other parts of Panama are an undescribed species. The population size of Z. skinneri, given this circumsciption is estimated to be less than 500. The new species are Z. hamannii, Z. mesophila, Z. imperialis
Population Trend:	Decreasing
