Caladenia leptochila subsp. leptochila, commonly known as the narrow-lipped spider orchid,[2] is a plant in the orchid family Orchidaceae and is endemic to South Australia. It has a single leaf and one or two yellowish or red flowers. It differs from subspecies leptochila in the colour of its flowers, lack of toothed edges to its labellum, and its distribution.
Caladenia leptochila subsp. leptochila is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect leaf, 100–200 mm (4–8 in) long and 8–12 mm (0.3–0.5 in) wide. One or two yellowish or red flowers 25–35 mm (0.98–1.4 in) in diameter are borne on a stalk 200–450 mm (8–20 in) tall. The sepals have thin, reddish, club-like glandular tips 5–8 mm (0.2–0.3 in) long. The dorsal sepal is erect, 40–65 mm (2–3 in) long and about 4 mm (0.2 in) wide. The lateral sepals are about the same size as the dorsal sepal but are turned stiffly upwards. The petals are 35–45 mm (1.4–1.8 in) long and about 3 mm (0.1 in) wide and spread horizontally or turn upwards. The labellum is 12–15 mm (0.5–0.6 in) long and 5–7 mm (0.2–0.3 in) wide and red with the tip rolled under. The sides of the labellum lack the teeth of subspecies dentata but there are four rows of short, red calli along its mid-line. Flowering occurs from September to November.[2]
