Corybas dowlingii, commonly known as red lanterns,[2] is a rare species of terrestrial orchid endemic to New South Wales. It grows in colonies and has a round or heart-shaped leaf and a dark purplish red flower with white patches in the labellum.

Description

Corybas dowlingii is a terrestrial, perennial, deciduous, herb with a single round or heart-shaped leaf {{convert|15-35|mm|in|sigfig=1|abbr=on}} long and wide. The leaf is dark green on the upper surface and slightly reddish on the lower side. A single erect, dark purplish red flower, {{convert|26-32|mm|in|sigfig=2|abbr=on}} long and {{convert|6-10|mm|in|sigfig=1|abbr=on}} wide is borne on a stalk {{convert|1-2|mm|in|sigfig=1|abbr=on}} long. The dorsal sepal is {{convert|15-23|mm|in|sigfig=1|abbr=on}} long, {{convert|6-10|mm|in|sigfig=1|abbr=on}} wide and curved. The lateral sepals are linear, about {{convert|2|mm|in|sigfig=1|abbr=on}} long and {{convert|0.5|mm|in|sigfig=1|abbr=on}} wide, tapered and held horizontally or turned upwards towards the labellum. The petals are about {{convert|0.5|mm|in|sigfig=1|abbr=on}} long and hidden behind the labellum. The labellum is translucent white with red blotches and tube-shaped near its base. The tube is about {{convert|4|mm|in|sigfig=1|abbr=on}} long then expanded into a flat area {{convert|10-12|mm|in|sigfig=1|abbr=on}} long and {{convert|5-6|mm|in|sigfig=2|abbr=on}} wide. There are two whitish spurs about {{convert|3|mm|in|sigfig=1|abbr=on}} long turning downwards from the base of the labellum. Flowering occurs from June to August.[2][3]

Taxonomy

Corybas dowlingii was first formally described in 2004 by David Jones from a specimen collected by Bill Dowling on Bulahdelah Mountain. The description was published in The Orchadian.[4] The specific epithet (dowlingii) honours the collector of the type specimen.[5]

Distribution and habitat

Red lanterns grows in gullies in tall forest and is only known from four localities between Bulahdelah, Port Stephens and Freemans Waterhole.[2][3]

Conservation

This orchid is listed as "endangered" under the New South Wales Threatened Species Conservation Act. It is threatened by land clearing and habitat degradation, rubbish dumping and recreational overuse.[3]
