Source-derived summary

Citrus longispina (winged lime, blacktwig lime, or megacarpa papeda) is an unusual sweet lime-like citrus that has been classed as a papeda.

It is called Tai la mi san in Chinese, Taramisan in Japanese and Tanisan or Talamisan in the Philippines.

Description

Citrus longispina is an attractive citrus tree with striking colors: a background of dark-colored twigs, pale green leaves, and pale yellow fruit. Twigs are unusually dark brown, almost black, hence the name "blacktwig". The tree can reach eight feet (2.4 m) in height, and often has a spreading bushy appearance. Twigs are commonly long and bent down by the heavy fruit load.

Fruits comes in clusters and the flesh has a fair amount of natural sugar and a lime flavor. However it still lacks the intensity of acid found in more common citrus fruits, so some people might find it insipid. The fruit is spherical, about eight cm (3.1 in) in diameter. The tree has many long, strong thorns, as implicated from the botanical name, longispina.

Editorial summary

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

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 168-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 Citrus, longispina and species.
Editorial analysis

Why this record matters

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

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 28, 2025. The linked authority identifier is Q19596388. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
