Pterostylis bryophila
species of plant
Pterostylis bryophila, commonly known as the Hindmarsh Valley greenhood, is a species of orchid endemic to South Australia. As with similar greenhoods, plants in flower differ from those that are not. In this species, plants not in flower have a rosette of leaves lying flat on the ground, but those in flower have a single small, shiny, bright green and white flower with a protruding, platform-like sinus between the lateral sepals.
Description
Pterostylis bryophila is a terrestrial, perennial, deciduous, herb with an underground tuber and when not in flower, a rosette of between three and five leaves, each leaf 10–22 mm (0.4–0.9 in) long and 5–15 mm (0.2–0.6 in) wide. When in flower, plants have a single flower 18–20 mm (0.7–0.8 in) long and 8–10 mm (0.3–0.4 in) wide on a stem 120–180 mm (5–7 in) tall with four or five stem leaves. The flowers are shiny, bright green and white and curve forwards. The dorsal sepal and petals are fused, forming a hood or "galea" over the column, the dorsal sepal pointed and longer than the petals. The lateral sepals are held closely against the galea, have erect thread-like tips 16–21 mm (0.6–0.8 in) long and a flat, protruding, U-shaped sinus between their bases. The labellum is 9–11 mm (0.35–0.43 in) long, about 3 mm (0.1 in) wide, curved, dark brown and just visible above the sinus. Flowering occurs from April to July.

Why this record matters
“Pterostylis bryophila” is worth following because a concise public description often conceals a longer documentary argument. Here, Pterostylis, bryophila and species provides the most credible route into that argument.
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 Oct 19, 2025. The linked authority identifier is Q15491663. 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 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.
