Caladenia microchila
species of plant
Caladenia microchila, commonly known as the western wispy spider orchid, is a species of orchid endemic to the south-west of Western Australia. It is relatively common orchid with a single erect, hairy leaf and up to three wispy white flowers with narrow lateral sepals and petals and a white labellum with red markings.
Description
Caladenia microchila is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, 80–120 mm (3–5 in) long and about 2 mm (0.08 in) wide. Up to three white flowers 30–90 mm (1–4 in) long and 30–60 mm (1–2 in) wide are borne on a stalk 90–250 mm (4–10 in) tall. The sepals and petals have long, dark, reddish-brown, thread-like tips. The dorsal sepal is erect, 35–70 mm (1–3 in) long, about 2 mm (0.08 in) wide. The lateral sepals are 45–70 mm (2–3 in) long, 2–3 mm (0.08–0.1 in) wide and turned stiffly downwards. The petals are 25–60 mm (1–2 in) long and about 2 mm (0.08 in) wide and held horizontally or slightly upwards. The labellum is 4–7 mm (0.2–0.3 in) long and 4–5 mm (0.16–0.20 in) wide, white with red stripes and spots and the tip is curled under. The sides of the labellum have short, blunt teeth and there two rows of creamish-white, anvil-shaped calli, sometimes with red tips, along the centre.
This brief starts where responsible research should: with the source description of “Caladenia microchila” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
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 14, 2026. The linked authority identifier is Q9673767. None of the 0 selected statements returned an explicit reference.
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.
