Castanopsis fissa
species of plant
Castanopsis fissa is a species of tree native to Southeast China, Hong Kong, Laos, Thailand and Vietnam.
The specific Latin epithet fissa means fissure, referring to its fruits splitting into segment when they mature.
Description
This species is a large evergreen tree that can reach up to 20 meters (66 ft) in height. Its bark is greyish-brown and becomes coarse with age, while the branchlets are red-purple with conspicuous ribs. The leaves are alternate, thick, and papery, highly variable in size and shape, ranging from oblong to obovate-elliptic, with a cuneate base and rounded, undulate, and crenate teeth on the lower half. Lateral veins are numerous, typically 15–20 pairs, raised on the underside; the upper surface is glabrous, while the lower surface is initially yellowish-brown puberulent but becomes glabrescent. Flowers are arranged in erect spikes forming panicles that resemble fireworks; they are unisexual, monoecious, and many-flowered, with white, clustered stamens. The fruit consists of an ovoid to ellipsoid cupule, slightly dark reddish-brown and tomentose, which fully encloses the nut when immature and splits into 2–3 irregular segments at maturity. Each cupule contains a single globose to elliptic nut that is reddish-brown in color.
Life cycle
The species flowers from April to June, and fruits from October to November.

Why this record matters
“Castanopsis fissa” is worth following because a concise public description often conceals a longer documentary argument. Here, Castanopsis, fissa and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q1048531. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
