Range: Marojejy National Park, northern Madagascar
A rare and little-studied species, this Madagascan endemic is thus far known only from the mountain for which the park it’s found in is named after, and Mount Manantenina; here, it grows from 1400-2137 meters in elevation in open vegetation in scrublands or subalpine meadows. Plants may reach 15-20 cm in length, most of which is a narrow, leafless stem left behind after years of growth and topped by a small rosette only up to 7 cm across with 2-6 active sub-linear leaves held upright to semi-erect. Petioles are around 2 cm long, un-tapered, and glabrous to sparsely covered in small hairs; the lamina are slightly longer and oblong to near-lanceolate, narrowing toward the tip or of equal width up to a rounded apex. Inflorescences are ascending, up to 15 cm in length and glabrous, bearing 2-10 blooms. Each flower is approximately 1 cm in diameter, with ovular, pale to bright pink petals. This species is readily distinguished from most other species and from its closest relative D. arachnoides by its lengthy stem, few and short active leaves, mostly glabrous nature, and lack of persistent senescent leaves.
Cultivation: grow in a 2:1 peat/sand mix, kept moist to wet but well aerated and humid with temps of 50-85°F daytime, cooler at night, year round. Keep slightly drier in summer, and sow seeds on the soil surface. Grow in strong artificial light to full sun.
Lifespan and reproduction: perennial. Reproduces through seed, and possibly leaf or stem cuttings.
