Catasetum integerrimum
These are photographs of the female flower at the top (green and sleek) and a male flower (looks like he needs a bath and a shave!) below. Catasetums, unlike Clowesias and Mormodes, have male and female flowers on separate flower spikes and normally at different times. This species is very common on the gulf slope/coast mainly at sea level from Tamaulipas to Tabasco. It is deciduous in winter and be careful with the spiny sheaths on the pseudobulbs. OUCH!!!
Please note that the picture of the male flower was kindly donated by Weyman's good friend Dr. Twan Tjoa of McAllen, Texas, a retired radiologist who photgraphed this flower grown by his lovely wife, Lien.
