Source-derived summary

Cycas balansae is a species of cycad in the genus Cycas, native to southwestern China (southeast Guangxi) and adjacent northern Vietnam (near Hanoi), where it occurs in dense mountain rainforests.

It has a subterranean, unbranched stem 12–20 cm in diameter, bearing 4-9 leaves, each leaf 1.2-2.6 m long, pinnate with 90-160 leaflets, and armed with spines along the petiole. The leaflets are papery in texture, and angled forward at 80 degrees.

The female cones are closed type, 8–12 cm long sporophylls with 2-4 ovules. Lateral spines present in lamina, apical spines not distinct, with yellow sarcotesta. The male cones are yellow, solitary, erect, 20–25 cm long and 4–7 cm diameter, with wedge shaped sporophylls.

Range

In northeastern Vietnam, Cycas balansae is found in Lang Son, Vinh Phuc, Thai Nguyen, and Quang Ninh provinces. In Guangxi, China, it is found in the Shiwan Dashan (mountains). In Yunnan, China, it is found in Jingping, Maguan, and Pingbian counties.

Cultivation

It is cultivated as a pot plant in its native range, but is not seen with any frequency outside of this area.

Editorial summary

“Cycas balansae” enters the record as species of plant. Crown Archives preserves that source wording while asking what Cycas, balansae and species can confirm, complicate or overturn.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 179-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Cycas, balansae and species.
Editorial analysis

Why this record matters

“Cycas balansae” is worth following because a concise public description often conceals a longer documentary argument. Here, Cycas, balansae and species provides the most credible route into that argument.

Evidence profile

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 5, 2026. The linked authority identifier is Q3284527. None of the 0 selected statements returned an explicit reference.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.

How to read it
