Abstract

Naturalization and invasion of alien species have made great impact on the global environment and social development, and have become global issues of biodiversity management and ecological protection. China is regarded as one of the countries that are the mostly threatened by biological invasion in the world, and faces severe challenges in the early warning, supervision and management of invasive alien species. Passiflora morifolia Mast., a newly naturalized plant of Passifloraceae from China, is reported in this article, its morphological description and related photos are provided too. P. morifolia is native to the tropical regions of central and South Americas, and was newly found in Menglian County, Yunnan Province, Southwest China. It is characterized by its leaves herbaceous, three palmately lobed, with sparsely short bristles, stipules ovate, semi-amplexicaul, cymes degenerate, bracts linear, with 1-2 flowers, pedicels 3-6 cm long, petals white, coronal purple at base, mature fruits purple, with short bristles and frost. In Chinese species, P. morifolia is the most similar to P. foetida, but the latter is with spreading pubescent and glandular hairs, petioles without glands, inflorescence bracts 1-3 pinnatifid, corona often pink at base. In addition, its potential harm and invasive risks are briefly assessed.
