Habenaria medusae orchid
This rare orchid species can grow up to 16 in. (40 cm) tall in. (cm) long tall when in bloom with an erect stem emerging from the center of a basal rosette of leaves.
About 7 per inflorescence. The flowers, which are about 1.3 in. (3.3 cm) wide when measured across the side lobes of the lip, are whitish and pale green. The egg-shaped dorsal sepal is sharply pointed, concave, and about 0.3 in. (0.7 cm) long. The lateral sepals are obliquely egg-shaped, sharply pointed, and about 0.3 in. (0.7 cm) long but a little wider than the dorsal sepal, measuring 0.2 in. (0.475 cm) wide. The narrowly linear, bluntly pointed petals are 0.2 in. (0.57 cm) long by 0.02 in. (0.05 cm) wide. The 3-lobed lip has spreading lateral lobes at the base that are divided into about 15 very narrowly linear, fringelike lobules that are up to 0.8 in. (2 cm) long by 0.01 in. (0.025 cm) wide. The linear mid-lobe is very convex and is about 0.2 in. (0.6 cm) long by 0.03 in. (0.07 cm) wide. There is a pendent spur at the base of the lip that is 1.2-1.6 in. (3-4 cm) long and is mostly thin but is slightly swollen along the apical 0.6 in. (1.5 cm).
To about 16 in. (40 cm) long. Flowers are placed about 0.2 in. (0.6 cm) apart from an apical raceme with a rachis that is about 1.6 in. (4 cm) long. Each blossom is subtended by a narrowly lanceolate, sharply pointed floral bract that is about 1 in. (2.5 cm) long by 0.1 in. (0.3 cm) wide
To about 6 in. (15 cm) long by 1 in. (2.5 cm) wide. Four of five lanceolate leaves that taper to sharply pointed tips are arranged in more or less spreading positions at the base of the stem.
Sumatra, Java, Borneo, and Sulawesi. In Sumatra, plants are found in southern Sumatra from Bengkulu to the Lampung district at about 1950 ft. (600 m). Plants in Java are found in only a few places in the northern half of East Java in areas that experience a long dry season at elevations of 350-3300 ft. (100-1000 m).
