Caladenia arrecta
species of plant
Caladenia arrecta, commonly known as the reaching spider orchid, is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It has a single erect, hairy leaf and up to three red, yellow and green flowers on a flowering stem up to 35 cm (10 in) high. It is distinguished from the similar C. longiclavata and C. magniclavata by its upswept petals and distinctive calli. Although not common, it is widespread in south-eastern coastal areas.
Description
Caladenia arrecta is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf 10–30 cm (4–10 in) long and about 2 mm (0.08 in) wide. The inflorescence is a raceme, 12–35 cm (5–10 in) high with up to three flowers. The flowers are 5–8 cm (2–3 in) long, 3–5 cm (1–2 in) wide and red, yellow and green. The dorsal sepal is erect and the lateral sepals have prominently clubbed, glandular ends pointing obliquely downwards. The petals are also clubbed but spread upwards. The labellum is red with fringes of pointed calli and two pairs of rows of deep red calli along its centre.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Caladenia arrecta”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.
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 31, 2024. The linked authority identifier is Q15287435. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
