CENTRAL AMERICAN ORCHIDS 
Caulis elongatus, gracilis. Folia approximata, subelliptica, 
in sicco valde membranacea, obtusa. Racemus congestus, 
flores subumbellati. Bracteae inflorescentiae squami- 
formes, acutae. Pedicelli graciles, oblique ascendentes. 
Sepala lineari-oblonga, margine valde revoluta. Petala 
fdiformia. Labellum valde concavum, vix auriculatum, 
apice obscure trilobatum; lobis lateralibus porrectis, obtusis; 
lobo medio producto, obtuso, lateralibus angustiori. Discus 
in medio carinatus. Columna brevis. 
Terrestrial herb up to 28 cm. high, bifoliate near the 
middle. Leaves approximate, 5.5 cm. long, 3 cm. wide, sub¬ 
elliptical, obtuse, membranaceous, mid-nerve prominent 
beneath. Peduncle, -— or stem, — above the leaves, 18 cm. 
long, very slender, longitudinally sulcate. Inflorescence sub- 
umbellate. Bracts of the inflorescence squamiform, about 
1 mm. long, acute, greenish, concave, much shorter than the 
slender pedicels. Flowers crowded. Pedicels obliquely 
ascending, with the ovary 5-12 mm. long, smooth, forming 
an obconical cluster. Lateral sepals nearly 4 mm. long, 
linear-oblong, obtuse, with the margin strongly revolute. 
Dorsal sepal similar. Petals filiform, 3.5 mm. long, obtuse. 
Labellum subsimple, 3 mm. long, without distinct basal 
auricles, about 2 mm. wide when flattened out, strongly con¬ 
cave, with a raised median carina within, obscurely 3-lobed 
at the tip; lateral lobes rounded and porrect; middle lobe 
narrower than the laterals and directed forward. Column 
short, hardly 1 mm. long. 
This is a close ally of Malaxis lagotis (Reichb. f.) Ktze., 
M. brachyrrhyncha (Reichb. f.) Ames and M. Javesiae 
(Reichb. f.) Ames. From M. lagotis it is at once separable 
by the single carina of the labellum. M. brachyrrhyncha has 
broad sepals and a different labellum. M. Javesiae is 
monophyllous with quite a different labellum.
