Quercus canbyi
species of plant

Quercus canbyi (Canby oak, Sierra oak), is a North American species of oak tree.
Description
Quercus canbyi is a semi-evergreen - evergreen tree, up to 40–50 feet (12–15 metres) tall in cultivation. Although, it can reach up to 80 feet (24 metres) in the wild in Mexico. It starts as a pyramidal form and then matures into an open irregular shape. It can reach a spread of 30–40 feet (9.1–12.2 metres) wide.
The dark, glossy green leaves are 6–8 inches (15–20 centimetres) long and have serrated edges. The petioles can have a reddish hue. It blooms in March and the acorns are then seen in August.
It has been distinguished from Quercus graciliformis by its twig shape and by producing acorns biennially rather than annually; however as of February 2023, Plants of the World Online regards them as synonymous.
Taxonomy
Quercus canbyi was first described by William Trelease in 1924.
“Quercus canbyi” enters the record as species of plant. Crown Archives preserves that source wording while asking what Quercus, canbyi and species can confirm, complicate or overturn.
Why this record matters
“Quercus canbyi” is worth following because a concise public description often conceals a longer documentary argument. Here, Quercus, canbyi 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 Jul 1, 2026. The linked authority identifier is Q6323318. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2023 and 1924.
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.
