Passiflora semiciliosa

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Passiflora semiciliosa faces significant pressure from agricultural expansion and urban development throughout its limited range in the Atlantic Forest region. Habitat fragmentation has isolated remaining populations, reducing genetic diversity and limiting natural pollination networks essential for this vine's reproduction. The species' specialized ecological requirements make it particularly vulnerable to microhabitat changes caused by edge effects in forest fragments.

Threat summary

Habitat

This passion vine inhabits humid Atlantic Forest environments, typically growing in secondary forest edges and clearings where it can climb on supporting vegetation. It requires well-drained soils and partial shade conditions found in the understory and forest margins of southeastern Brazil's coastal mountain ranges.
