Wax gourd
species of plant, winter melon

Benincasa hispida, the wax gourd, also called ash gourd, white gourd, winter gourd, winter melon, tallow gourd, ash pumpkin, dongah or Chinese preserving melon, is a species of gourd.
The wax gourd is native to South and Southeast Asia. It is grown, especially in Asia, for its very large fruit, eaten as a vegetable when mature. One variety of the plant, called chi qua (Benincasa hispida var. chieh-qua), is commonly used in Asian cuisine.
Description
The plant grows thick vines with coarse and hairy stems. It has large, rough leaves with a width between 10–30 centimetres (4–12 in) long.
In early summer from June to September, golden yellow flowers form in the leaf axils.
After they are pollinated, they bear obloid fruit 50–60 cm (20–24 in) long and 10–25 cm wide. They typically weigh 5–10 kg, with weights of up to 34.5 kg recorded.
Begin with the source’s own compact description: “Wax gourd” is species of plant, winter melon. The dossier treats that line as a proposition to test through gourd, species and plant, not as a finished interpretation.
Why this record matters
The phrase “species of plant, winter melon” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q652206. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
