AFRICAN

ORCHIDS

Habenaria section Diphyllae Kraenzl. in Bot. Jahrb. Syst. 16: 56, 147 (1892).
Description:
Plants with one or two basal leaves adpressed to the ground and several sheath-like leaves scattered up the flowering stem. It is a heterogeneous group comprising some species that are florally very different, and includes some of the most attractive species, several well worth cultivation. However they tend to be reluctant to flower; in the field, any colony has usually many more non-flowering than flowering plants. This is taken to extremes in some of the one-leafed species, in particular H. nyikensis, where it is possible to find literally hundreds of leaves without seeing a single flowering plant.
