Loefgrenianthus is an orchid genus formed by only one very rare small epiphytic species, Loefgrenianthus blanche-amesiae, inhabitant of Serra do Mar mountains in Brazilian southeast. It can be differentiated from its closest genus, Leptotes, both because of its pending vegetation with flat leaves and the flowers which have a saccate labellum.
Distribution and habit
Loefgrenianthus blanche-amesiae is a small epiphytic species which inhabits the highest areas of Atlantic Forest of Rio de Janeiro, São Paulo and Paraná States of Brazil,[1] particularly in Serra da Mantiqueira and Serra do Mar chains of mountains, where it is very rare. It grows under the shadow of trees in shady, humid and well ventilated woods, between 1,000 and 2,200 meters of altitude on mountains slopes. It ordinarily grows at middle height, pending from thick stems, mostly of Podocarpus and Araucaria species,[2] despite there are records of plants occasionally growing in thin branches too.[3]
