Mexican Stan tigrina is the most cultivated Stanhopea (and one of the most beautiful!). It has short spikes, with only two or three BIG flowers!; this clone is dark for a "type", but the "dented" hypochile and the yellow spots in the sepals (red arrows) doesn't exists in the variety nigroviolacea (considered a species for some botanists). Stan tigrina var. nigroviolacea has even BIGGER flowers (the heaviest flowers amongst all Stans), a globous hypochile (not dented) and a uniform, solid dark purple color in the sepals, with a few of yellow in the borders.
