In the study of habitats completed by G.F.S. Pabst and F. Dungs in Orchidaceae Braziliensis
they have indicated the representative temperature range for this habitat is 23 to 35oC. with a typical maximum
range during the year of 17 to 40oC. Humidity is typically within the range of 65 to 90%, with the diurnal temperature
variation of 15oC. being normal. The maximum temperature differential is 23oC.
From the cultural perspective, this habitat produces plants generally classified as requiring
warm or intermediate temperatures. Humidity should be maintained at a high level all year, with comparatively constant
At the equator the widespread flowering trigger of day length is often not applicable,
as there is little day length variation throughout the year in equatorial regions. It is often the variation in
rainfall that is the factor initiating flowering, and the particular rainfall pattern relevant to a particular
species can be of assistance where flowering difficulties are experienced. If water can be withhold
for a period during the plants natural habitat dryer period this will often stimulate flowering of such plants.
To repeat an earlier comment, the fact that plants from this habitat often do not receive
full sun much of the year is something we must consider, especially with the generally strong natural light conditions
normally experienced in New Zealand. Remember, however, that plants generally flower better in bright conditions
and the control of temperatures and maintenance of higher humidity levels and good air movement will facilitate
