Inflorescence generally 6cm. long, many flowered, flowers appearing nearly to the base, slightly longer than the leaves; bracts small, obtuse. Sepals oblong-elliptical, obtuse, narrow and long (generally 6 mm long). Petals elliptical, obtuse, attenuate at both ends, longer than the sepals and slightly narrower. Labellum elliptical, longer than the petals, wider medially (to 3.25 mm), deeply concave; spur 8 mm long, narrowly cylindrical, dilate apically. Column shortly attenuate basally; dorsal margins of the clinandrium slightly enlarged; rostellum enlarged and recurved apically; viscidium sub truncate, large by comparison to the pollina globules.

Notes:
Aerangis hyaloides can best be described as a little gem, and it bears out the contention that "the best things come in small packages." It is not unusual for this plant to carry 200 flowers, and with its many little inflorescences covered with cup-shaped, starlike, glistening, waxy, snow-white flowers literally enveloping its emerald-green leaves, covering them with "snow," it gives the impression of a miniature bridal wreath. Actually, the best epithet for a well-grown plant in bloom would be "snowstorm." In spite of being only slightly scented, this tiny plant is highly recommended for maximum enjoyment in a limited amount of space, since it should never outgrow a 21/2-inch pot. The species flowers in January in the northern hemisphere.
Distribution:
E. Madagascar
