ORCHIDS

Rhaesteria Summerh., Kew Bull. 20: 191 (1966).
Description:
It is remarkable for the small size of the plants and for the partly united sepals and petals. It also has a broad, convex lip encircling the column at its base, and the elongated rostellum somewhat resembles the head of a hammer.
Distribution:
SW. Uganda to Rwanda.
Cultivation:

Notes:
In 1966 Summerhayes coined the name Rhaesteria in allusion to this last feature (from the Greek rhaester, a hammer). The single species is named after the collector W. J. Eggeling.
