Description
editSarcochilus parviflorus is an epiphytic, rarely lithophytic orchid with sparsely branched stems 30–80 mm (1–3 in) long with between two and eight leaves. The leaves are dark green, rigid, egg-shaped to narrow oblong, 80–150 mm (3–6 in) long and 30–40 mm (1–2 in) long wide. The flowering stems are 90–140 mm (4–6 in) long and bear between two and twelve bright green to yellowish green flowers 18–22 mm (0.7–0.9 in) long and 20–25 mm (0.8–1 in) wide. The sepal are 10–15 mm (0.4–0.6 in) long and 3–4 mm (0.1–0.2 in) wide whilst the petals are narrower. The labellum is 6–8 mm (0.2–0.3 in) long, 4–5 mm (0.16–0.20 in) wide and greenish cream with reddish markings. The labellum has three lobes, the side lobes curving upwards near their tips and the middle lobe with a short tooth on its midline. Flowering occurs between June and January.[2][3]
Taxonomy and naming
editSarcochilus parviflorus was first formally described in 1838 by John Lindley and the description was published in Edwards's Botanical Register.[4][5] The specific epithet (parviflorus) is derived from the Latin words parvus meaning "little"[6]: 489 and flos meaning "flower".[6]: 45
Distribution and habitat
editThe southern lawyer orchid grows on trees, rarely on rocks, in rainforest in coastal areas and nearby tablelands between Brisbane and Tathra.[2][3]
