Leaf 6 or 8 inches long. linear-lanceolate, carinate, acutely tridenticulate, bright green, narrowing 
below into a grooved petiole. sheathed at the base. 
Peduncle about 5 inches long, terete, slender, jointed, with a sheathing apiculate bract at each joint, 
lateral or descending from the base of the petiole, with two or three flowers expanding in succession, dull 
purplish-green ; flowering bract about 3 inch long, ovate-apiculate, sheathing below, pale green. 
Ovary nearly 4 inch long, curved, with six rounded angles, crimson-purple. 
Sepals : dorsal sepal united to the lateral sepals for | inch, forming a wide shallow cup, free portion 
triangular-ovate for about inch ; lateral sepals cohering for 4 inch, rounded beneath, free portions 
triangular-ovate for more than 3 inch ; all creamy white, tinged with yellow, and more or less spotted 
with crimson-purple, the inner surface covered with small elongated papilla, with numerous nerves, of 
which the central ones are prominent on the outer surface, terminating in slender terete crimson-purple 
tails 1 or 2 inches long. 
Petals about 4 inch long, oblong, margins angled, apex bilobed, with a mass of minute dark- 
brown papille within the cleft, white or pale pink, with a few brown spots, apex yellowish. 
Lip about 4 inch long, curved and fleshy at the base, and united to the foot of the column by a very 
flexible hinge. deeply grooved, the anterior portion saceate, with three central keels and five or six 
smaller bifurcated keels radiating towards the toothed margin, very pale pink, sometimes nearly white, 
with a very few pale pink spots. 
Colunin a little longer than the petals, narrowly winged, apex denticulate, pale vellow. 
HE first specimens of Musdecallia erythrochete were introduced from Central 
America by Mr. Sander, of St. Albans, in 1882. Numerous varieties are now 
known, and two of these were named by Reichenbach as distinct species—AZ. astuta, 
brought from Costa Rica by Carder, and AL, Gaskelliana, a plant with smaller leaves and 
flowers, of which the habitat is unknown. One beautiful variety has much wider leaves 
than the plant here represented, and larger flowers, which are nearly white, delicately 
tinged with sulphur-yellow, and with only a few bright crimson spots, the tails being 
reddish-crimson and the lip pink. The accompanying woodcut is from a photograph of 
this variety.
