Leaf 4 or 5 inches long, oblong-ovate, apex acutely tridenticulate, narrowing below into a slender 
grooved petiole sheathed at the base, bright green. 
Peduncle about 2 inches long, terete, slender, erect from the base of the petiole, pale green ;_ bract 
nearly 4 inch long, ovate-apiculate, sheathing below, with a minute rudimentary bud within at the base, 
pale green. 
Ovary J inch long, curved, with six rounded angles, pale green. 
Sepals all cohering for about 3 inch, forming a narrow tube, gibbous below, free portions roundly 
triangular, 3-nerved, pure white, each with one rose-crimson streak, and all terminating in terete bright 
orange-tails nearly 1 inch long. 
Petals less than } inch long, oblanceolate, with a thick angled keel on the anterior margin and a 
small one near the opposite side, acuminate, pure white with a green apex. 
Lip longer than the petals, thickened at the base and united by a hinge to the foot of the column, 
with two angled longitudinal keels, terminating in a velvety crimson cushion, pale yellow, apex slightly 
crenate, orange-yellow. 
Column shorter than the petals, slender, narrowly winged, apex denticulate, white, with a narrow

LTHOUGH Masdevallia 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. Krinzlin, of Berlin, in honour of his friend Herr Lauche, of Eisgrub, 
Austria. I 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 yellow.
