These colonies of Sphatoglottis plicata and Spa. plicata var. alba were obliterated when the road was repaired from damage






These orchids were growing on a fern prairie next to highest point of highway 10 in Puerto Rico.  Unfortunately, the road on this spot, started cracking and slumping.  A massive rework of the down slope side of the road was done to protect the road from further damage and to repair it.  The whole area was denued and reshaped.  Some day I will return to see if the orchids have returned.  However these particular orchids are abundant in the extreme in certain estreches of this road.  In this places even constant removal of plants by people that stop to uproot them, seems to make no dent in the populations.

Epidendrum boricuarum Hágsater & Sánchez Mata 1993, "in situ" in the Rio Abajo Forest






This species is found in Hispaniola and in Puerto Rico, is also probably found in other neighboring islands (Ackerman 2014).  It is similar to Epidendrum difforme and for many years it was considered this species.  I have seen it in many places growing in live and dead trees.  It is a common species.    I have previously photographed this species in situ in El Yunque mountain in the Sierra de Luquillo.   The photos here are from the karst region of Puerto Rico near the center of the island.  These photos were taken at roughly 1000 feet of altitude in the Rio Abajo forest.  The plants are growing on trees close to the edge of a wetland.  Humidity in the area is very high and the soil is permanently wet.

It is not uncommon to see plants of this species in captivity.  I have seen plants that seemed to have been in captivity for many years but these are a small minority and are either in the hands of skilled orchidists or of people that live in this orchid habitat.  I suspect that these plants fare poorly when removed from the wild mainly due to the lack of knowledge of the collectors of its particular care these plants need to survive in captivity.    In general orchids from the mountainous interior of the island, which is wet and relatively cool tend to fare very poorly when they are taken to the drier, much hotter environment that prevails in the coastal lowlands and then not provided with the level of humidity that prevails in their habitat.

Bletia patula var alba Hawkes 1950, a rare sighting

Fully mature flower

Newly opened flower
I had heard of Bletia patula alba for many years but had never seen one “in the flesh”.  Yesterday in the Mayaguez Orchid festival I finally was able to see one.  A plant of this type was awarded by the AOS many years ago, but so far as I know that plant was lost.  I found a very pale form of this species in the wild some years ago, but in all my field trips I have never seen an alba in the wild.  In some areas of Arecibo I have seen fields where there were thousands of plants but all of them were uniformly colored.  I would hope that this clone will be selfed and the seed sown or some divisions are distributed among hobbyists so that it is not lost again.
