Lemurorchis Kraenzl., Bot. Jahrb. Syst. 17: 58 (1893).
This strange orchid genus is represented by a single species that has been infrequently collected in central Madagascar. The genus was established by German botanist Fritz Kraenzlin in 1893, when he described a specimen collected by botanist-explorer J. M. Hildebrandt, who travelled widely in Africa and Madagascar. The generic name seems to refer to the geographic location for this orchid (see also Lemurella).
The habit of the plant with its long, folded leaf bases overlapping around a short stern is quite distinctive. It looks like some of the large plants of Jumellea and even more like a large Phreatia, although the leaves are quite leathery. The inflorescences are axillary and quite long, though usually shorter than the leaves, and the small white flowers are borne very close together.
Type species:
Lemurorchis madagascariensis Kraenzl.
This epiphyte is endemic to a small remnant of evergreen forest at about 2000 m above sea level, near Antananarivo.
In a glasshouse it grows best in cool and semi-shady conditions with high atmospheric humidity. Mature plants can be quite large and are therefore best potted in compost that is free draining and contains some moisture-retentive material. The pendent inflorescences are produced readily but abort easily when temperatures are too high and humidity is too low.
