Lycaste Linguella ; pseudobulbis lagenaeformibus sulcatis compressis, foliis 
membranaceis elongato-lanceolatis acuminatis plicatis, scapis robustis, 
spatliis obtusis, bractea coriacea obovata cucullata obtusiuscula ovarium 
superante, floribus flavo-virescentibus labello pallidiore, sepalo dorsali 
obovato-oblongo obtuse apiculato, lateralibus majoribus deflexo-curvatis 
subacutis, petalis late obovatis obtuse apiculatis, mento in cornu obtusum 
producto, labelli dimidio basilari crasso valde concavo lobis lateralibus 
angustis disco intra lobos in callmn semicircularem protrusum linguseformi 
truncato labello aequilato producto, lobo intermedio callo supposito linguse- 
formi recurvo late ovato obtuso eroso, columnse basi puberulo.

This fine Lycaste is remarkable for the structure of the lip, 
which, as indeed is the case with so many orchids, is difficult 
to describe. The body of this organ forms a coriaceous semi- 
cylindric tube, with the narrow lateral lobes appressed to its 
sides, whilst the front part is protruded as a truncate fleshy 
spout, and the mid-lobe, which arises on both sides from the 
base of the lateral lobes, is for the rest of its breadth attached 
to the back of the gutter, from which it appears to hang as a 
broad erose tongue. That this is after all only a modification of 
the prevalent character of the lip of Lycaste is obvious on 
comparing that of Z. Linguella with any other figured in 
this work. In Z. lasioglossa (Tab. 6251), the gutter is reduced 
to a tongue-shaped callus concealed in the concavity of lip. In 
Z. Barring tonice ( Tab. 5706), Z. fulvescens (Tab. 4193), and 
Z. Skinneri (Tab. 4445), it forms a similar but larger tongue, 
which approaches that of Z. Linguella in being concave and 
very fleshy; whilst in Z. gigantea (Tab. 5616) the tongue 
extends across the disk of the lip almost to the angles of the 
lateral lobes. In none of these, however, does it protrude as 
in the present species. 
Z. Linguella is, according to Beichenbach, supposed to 
JUNE 1st, 1877.
