Classification
Begonia fulgurata is a newly discovered species of Begonia. It belongs to the section Diploclinium within the Begonia genus.
Distribution
This species is endemic to Chiang Mai Province in northern Thailand, specifically in the Doi Lohn area. It is known only from the type locality.
Habitat
Begonia fulgurata can be found in epipetric or terrestrial habitats. It has a tuberous growth habit and is adapted to the local conditions of northern Thailand.
Characteristics
Begonia fulgurata is a monoecious, perennial plant. It has erect or ascending stems that can grow up to 40 cm in length. The leaves are oblique, pendent, and distant, with ovate-lanceolate to widely ovate lamina. The upper side of the leaves is characterized by fine silvery-white venation, resembling lightning. The inflorescence is a terminal, bisexual, cymosely branching panicle. Staminate flowers have two tepals, while pistillate flowers have five tepals. The ovary is 3-locular.
Flower Details
Staminate flowers of Begonia fulgurata have two white to pinkish tepals, and the androecium is zygomorphic with approximately 25 yellow stamens. Pistillate flowers have a pedicel, a pale green or pinkish ovary with three wings, and five white to pinkish tepals. The styles are yellowish green and bifid.
Etymology
The specific epithet "fulgurata" is derived from the fine, silvery-white venation on the upper surface of the leaves, which resembles lightning.
Comparison to Similar Species
Begonia fulgurata shares some similarities with other Begonia species like B. integrifolia and B. grandis in terms of having tuberous growth, erect stems, and a periodically dormant habit. However, it can be distinguished by its densely hirsute leaves with maroon patches and silvery-white veins, as well as the dense glandular hairy inflorescence and specific characteristics of its flowers.
