Description

edit

Dendrobium litorale is an epiphytic herb with very short rhizomes and crowded stems 300–600 mm (10–20 in) long and 5–10 mm (0.2–0.4 in) wide at the widest point. The leaves are arranged in two rows, and are flattened, fleshy and pointed 30–60 mm (1–2 in) long and 30–80 mm (1–3 in) wide. The flowers are arranged along leafless parts of the stem and are pale greenish cream, 10–15 mm (0.4–0.6 in) long and 10–12 mm (0.4–0.5 in) wide. The dorsal sepal is 4–5.5 mm (0.16–0.22 in) long, about 4 mm (0.16 in) wide and the lateral sepals are 8–10 mm (0.3–0.4 in) long and 4–5 mm (0.16–0.20 in) wide. The petals are 4–5 mm (0.16–0.20 in) long and about 2 mm (0.08 in) wide. The labellum is 10–12 mm (0.39–0.47 in) long, 7–10 mm (0.28–0.39 in) wide and has three lobes. The side lobes are blunt and the middle lobe has a central notch. Flowering occurs in April and July.[2][3]

Taxonomy and naming

edit

Dendrobium litorale was first formally described in 1912 by Rudolf Schlechter and the description was published in Repertorium Specierum Novarum Regni Vegetabilis Beihefte.[4][5] The specific epithet (litorale) is a Latin word meaning "of the seashore".[6]

Distribution and habitat

edit

The coastal shaggy orchid grows on trees in lowland rainforest and beach scrub on Dauan Island in the Torres Strait and in New Guinea.[2][3]
