LTHOCGH Masdecallia Laucheana has been known in cultivation for five or six 
years, no drawing or botanical description of it has hitherto been published. “It 
was named by Dr. Kriinzlin, of Berlin, in honour of his friend Herr Lauche, of Eisgrub, 
Austria. [can obtain no information as to its origin or habitat. A very pretty variety 
is grown in Sir Trevor Lawrence’s collection of Masdevallias, which has a rose-coloured 
spot upon the angle of the dorsal and lateral sepals, and three streaks of the same 
colour upon the dorsal sepal. The tails of this flower are of a richer orange than those 
of the type. and the lip is very pale vellow.
