CÚlestin Alfred Cogniaux,
This dioecious member of the Cucurbitaceae
family was described by CÚlestin Alfred Cogniaux
in 1881. It is found in the south-western part of Madagascar,
growing in a well drained soil or even grit with some water and some
sun. The caudex can grow to at least thirteen centimetres in
diameter, and the whole plant can grow to 60 centimetres or more.
The genera name is derived from
two Greek words, trochos; 'a wheel' and meris; 'a
part'. The connection to the plant is rather obscure; perhaps the
long, narrow corolla lobes look like the spokes of a wheel? The
species name for the different shaped leaves.
