harrisoniaes grow at sea level and some river valleys up to 500m
always on the edge of rivers in this case
loddigesiis grow >400 m and only in the inner country, they do not occur by the sea
lips have a different shape
although the sprout exactly at the same time
harrisonianas flower imediately as the bulb matures
whereas loddigesii enter a 6 month rest and flower only after that and before sprouting again
because of this detail, harrisonianas flower from a green spathe
whereas loddigesii the spathe withers during the rest, and they flower from a dry spathe
 the color tends to be a lot paler in loddigesii,
not only the pink,the yellow in the lip is kinda pale
whereas in harrisoniana it is often bright yellow
Cattleya
harrisoniana var. coerulea, award 20151208, has been determined to be Cattleya loddigesii
(coerulea) by SITF (March 2016).

The
fotos we have make calling this a coerulea a hard call, so if you feel this is
blue and not lavender as in the description, then add the (coerulea) to
the name, otherwise, Â if it is not
coerulea then the ID is Cattleya loddigesii.Â
