==== Description ====
==== Classification and Distribution ====
- **Growth Habit:** Monoecious, epipetric, perennial, and rhizomatous.
Begonia subcoriacea is a monoecious, epipetric perennial species that belongs to the Begonia genus.
- **Rhizome:** Rather stout, 5-15 cm long, and 0.6-1.2 cm thick, with brown color, villous when young, and glabrate when old.
 
- **Stipules:** Triangular-ovate or narrowly so, 1-2 cm long, and 0.8-1.4 cm wide, brownish, herbaceous, keeled or weakly so, with abaxial hairs, ciliate or ciliolate margin, and an arista of 3-4 mm.
==== Habitat ====
- **Leaves:** Alternate, simple, asymmetric, unlobed, widely ovate or suborbicular, with a strongly oblique cordate base and an inconspicuously irregularly repandly denticulate and ciliolate margin. The apex is shortly acuminate, and leaves measure (10-)12-20(-22) cm long (including basal lobes) and (8-)10-14(-17) cm wide. Adaxially, they are green and may have white maculation between major veins. Abaxially, they are pale green, yellowish green, or reddish, especially near major veins. The leaves are subcoriaceous, flat, adaxially glabrous, and abaxially tomentose on major veins and sparsely pilose on tertiary venation.
This begonia species thrives in broadleaved forests, particularly on semishady slopes of limestone hills.
- **Venation:** Basally 6-7-palmate with a distinct midrib and 1-3 major lateral veins on each side. Other primary veins dichotomously branch or nearly so, and tertiary veins are reticulate or percurrent. Minor veins are reticulate, with major (1° & 2°) veins on the abaxial surface prominently raised.
- **Petiole:** Terete, 9-20 cm long, 3-7.5 mm thick, greenish or brownish, tomentose.
- **Inflorescences:** Axillary, 1-6 in number, arising directly from the rhizome. They are diffusely cymose, branched 3-7 times.
- **Flower Characteristics:** Staminate flowers number 20-60, while carpellate flowers number 10-32. Peduncles are well-developed and red, with reddish glandulose-pilose trichomes.
- **Fruits:** Dehiscent capsules that are nodding and red when fresh. They measure 6.5-11 mm long and 5-6 mm wide (wings excluded). Lateral wings are 2-3 mm wide, and the abaxial wing is crescent-shaped or triangular, 2.5-5 mm high.
- **Seeds:** Numerous, brown, ellipsoid, or ovoid-ellipsoid, measuring about 0.4-0.5 mm long and 0.27-0.3 mm across, with chalazal end rounded and micropylar end obtuse. Outer periclinal walls of mature seeds are concave, and collar cells are elongated and nearly rectangular.
