Source-derived summary

Pinus devoniana (synonym Pinus michoacana) is a species of conifer in the family Pinaceae. It is found in more than 15 states of Mexico - from S. Sinaloa to Chiapas - and Guatemala in montane, relatively open pine or pine-oak forests at altitudes from 900 to 2,500 m (3,000 to 8,200 ft).

Pinus devoniana, which is locally called "pino blanco", "pino lacio" or "pino prieto", is a tree of medium size, which can grow 20–30 m (66–98 ft) tall, with a dbh to 80–100 cm (31–39 in). It has curved foliage twigs and very long needles, typically from 25–40 cm (9.8–15.7 in), though Mirov cites needles up to 50 cm (20 in) long, in fascicles of 5. The cones, which grow solitary or in whorls of 2-4 on thick, short peduncles, leaving a few scales on the branch when falling, are usually large and often curved, 15–35 cm (5.9–13.8 in) long and 8–15 cm (3.1–5.9 in) wide when open.

Pinus devoniana is closely related to Pinus montezumae (the Montezuma pine). These species are sometimes difficult to distinguish, while hybrids probably occur. The cones are especially variable. Overall, both foliage and cones are larger in Pinus devoniana.

Editorial summary

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

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 210-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 Pinus, devoniana and species.
Editorial analysis

Why this record matters

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

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Apr 27, 2026. The linked authority identifier is Q2744082. 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 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

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