LATE and EARLY

Common Name Bergold's Catasetum [German Orchid Enthusiast in Venezuela late 1900's]

Flower Size male .8" [2 cm] female 1.2" [3 cm]

Found in Venezuela in lowlands on granite outcrops at elevations of 50 to 400 meters as a large sized, hot growing lithophyte or terrestrial related to C ochraceum that blooms in the late summer and fall on a newly arising growth with an erect, thick, 18" [45 cm] long, few flowered female inflorescence. The orchid has fusiform pseudobulbs enveloped completely by leaf-bearing sheaths and carrying plicate, subcoriaceous, oblanceolate, acute to shorly acuminate, articulated to the leaf sheaths below, 3 nerved leaves.

The third pictured flower above taken by me is a female flower and it is a bit past it's prime and I personally have not seen the male flower.

Related to Catasetum ochraceum which occcurs in a much higher elevations mainly 400 to 1700 meters and differs primarily in the height and depth of the labellum [5:4 instead of 2:3] and the divergent antennae and the much longer [over 1/2"] antenna length as well as the much narrower [3/8"] petals.
