Featured blooms in the Atlantic Forest, March 2023

Houlletia brocklehurstiana Lindl.

A terrestrial plant in rich forest soil, pseudobulbs are oblong ovoid and bear a single, long petiole leaf with a recurved, somewhat convex blade.
It is a large plant that reaches about 50 cm with an incredibly heavy inflorescence whose flowers are drooping, inclined downwards.
The flowers are fleshy and large, the fruits are extremely rare, I found them only once in over 15 years of observation.
It is interesting to note that the column does not have a stigma, but a very narrow cavity where the pollinae must be deposited to the millimeter by a specific bee.
A true jewel of the Atlantic Forest, a spectacular orchid.
They can be found in the most varied types of environments, as a rule they seem to like brighter places and with always humid soil, apparently they are not very demanding in terms of habitat.

"Very ornamental, but very difficult to get in crops.
In the lowlands closer to the sea, the flowers tend to be more developed and have a more prominent lip with lateral lobes at the base." (Hoehne, Flora Brasilica Vol XII VI)

Huntleya meleagris Lindl.

A lush plant that forms sizable colonies in the middle and lower parts of trees growing in a spiral with its beautifully fan-shaped leaves apparently collecting debris that falls from the canopy.
The flowers are large and unique, with details that impress.
It is a plant that appreciates places with intense humidity.

Epidendrum bothryanthum M.R.Miranda et al.

One of the many alliance species of the Epidendrum proligerum group, plants whose stems ramify successively forming new shoots and inflorescences.
A group difficult to identify given the proximity between the species, E. bothryanthum is probably the smallest species in the group, very delicate with an inflorescence that resembles a small bunch of grapes, hence the name bothryanthum (Greek).
Inhabits the thin, sunny forests in the inselbergs close to the sea.
