Habenaria rumphii
species of plant
Habenaria rumphii, commonly known as stiff rein orchid, is a species of orchid that is widespread and common in Southeast Asia, New Guinea and northern Australia. It has six or seven leaves on the lower part of its stem and up to thirty white flowers with one long and two short lobes on the labellum.
Description
Habenaria rumphii is a tuberous, perennial herb with six or seven leaves on the lower part of the stem. The leaves are linear to lance-shaped, 60–140 mm (2–6 in) long, 15–20 mm (0.6–0.8 in) wide and stiffly pointed. Between ten and thirty white flowers 7–8 mm (0.28–0.31 in) long and 10–12 mm (0.4–0.5 in) wide are borne on a flowering stem 300–500 mm (10–20 in) tall. The dorsal sepal and petals overlap at their bases and form a hood over the column. The dorsal sepal is about 5 mm (0.2 in) long and 3 mm (0.1 in) wide and the lateral sepals are slightly longer and spread apart from each other. The petals are a similar length to the sepals but narrower. The labellum is 6.5–7.5 mm (0.26–0.30 in) long and about 3 mm (0.1 in) wide and has three lobes. The middle lobe is 5–6 mm (0.20–0.24 in) long and 1.5 mm (0.06 in) but the side lobes are only about half as long and wide.
This brief starts where responsible research should: with the source description of “Habenaria rumphii” 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 Oct 24, 2025. The linked authority identifier is Q15482814. 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 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.
