ORCHIDS FROM POTSDAM. 
WE have received several very beautiful flowers from Herr C. F. Karthaus, 
Orchideengartnerei, Potsdam, Germany. A very fine form of Cattleya X 
Hardyana, called Potsdam var., has blush pink sepals and petals, the latter 
darker towards the margin, and distinctly veined with white, while the 
lip is rich purple-crimson, with deep yellow veining on the disc, and two 
large yellow blotches on either side. A form of C. X Octave Doin has 
blush pink sepals and an undulate almost blackish-crimson lip, closely 
veined with deep yellow in the throat. A fine hybrid derived from C. 
granulosa Schofieldiana x C. labiata is a form of C. x Imperator, and has. 
rosy purple sepals and petals, and a strongly three-lobed lip, all the lobes 
being purple crimson in colour, with a clear lilac, crisped margin all round, 
and a trace of yellow on the sides of the isthmus. A flower from a plant 
purchased as Cattleya x Iris x Lelio-cattleya luminosa is a little gem,
