Caladenia crebra
species of plant
Caladenia crebra, commonly known as the Arrowsmith spider orchid, is a species of orchid endemic to the south-west of Western Australia. It has one or two relatively large, greenish-yellow flowers whose lateral sepals have thin brown "clubs" on their ends.
Description
Caladenia crebra is a terrestrial, perennial, deciduous, herb with an underground tuber and a single hairy leaf, 10–20 cm (4–8 in) long and 6–10 mm (0.2–0.4 in) wide. In August or September it produces one or two flowers on the end of a stalk 25–50 cm (10–20 in) tall, each flower 50–60 mm (2.0–2.4 in) wide. The flowers are greenish-yellow, sometimes with red markings. The dorsal sepal is erect, 25 mm (1 in) long and 3–5 mm (0.1–0.2 in) wide. The lateral sepals are 25–45 mm (1–2 in) long, 4–7 mm (0.2–0.3 in) wide and may spread widely below the flower or cross each other. The sepals have thin brown "clubs" 6–10 mm (0.2–0.4 in) on their ends. The petals are 25–30 mm (0.98–1.2 in) long, 3–4 mm (0.1–0.2 in) wide and curve backwards. The labellum is greenish-yellow, 12–15 mm (0.5–0.6 in) long, 10–12 mm (0.4–0.5 in) wide with many upturned, narrow teeth up to 6 mm (0.2 in) long, along its sides, often with hooks on their ends.
Begin with the source’s own compact description: “Caladenia crebra” is species of plant. The dossier treats that line as a proposition to test through Caladenia, crebra and species, not as a finished interpretation.
Why this record matters
The phrase “species of plant” 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.
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 Jun 11, 2026. The linked authority identifier is Q9673489. 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 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.
