columnam convolutis apicibus reflexis ; labelli trilobi lobis lateralibus 
erectis truncatis, intermedio longiore ovato rotundato deflexo, appendice 
carnosa lingueeformi inter lacinias laterales locata ; columna subtus pu- 
beseente Guatemala . The flowers measure upwards of six inches 
across, from the tips of the lateral sepals, while the latter are nearly an 
inch and half wide in the broadest part. The sepals are pure white, 
faintly tinged with crimson at the base the petals of a more rosy hue; 
the lip is almost covered with spots and streaks of the most brilliant car- 
mine. The column is pure white at the apex, and mottled with crimson 
spots at the base ; while a number of woolly hairs are scattered on its 
under side. 
8. L. aromatica (Maxill. aromatica, Hooker Ex. Flor. t. 219. L. no. 20. Bot. 
Reg. t. 1871. Colax aromaticus, Spreng.) ; vaginis distantibus obtusis 
cucullatis ; sepalis ovato-oblongis petalisque conformibus acutis, labelli 
semicylindracei sepalis sequalis laciniis lateralibus acuminatis obtusis 
intermedia, cuneata apice serrulata; appendice magna concava carnosa 
truncata, columnse facie villosa. Mexico. The flowers yellowish- 
orange, scarcely spotted even inside the lip, which has two rows of hairs 
along its inner face. 
9. L. cruenta (Maxill. cruenta, Lindl. in Bot. Reg. 1842. t. 13.); pedunculis 
raro bifloris, vaginis distantibus obtusis cucullatis, sepalis ovatis obtusis 
lateralibus basi parum productis, petalis minoribus conformibus, labello 
sepalis duplo breviore concavo trilobo laciniis rotundatis intermedia 
crispa pubescente : tuberculo parvo piano, columna pubescente. 
Guatemala. Resembles L. aromatica , but its leaves are broader; the 
flowers are four times as large when in health ; the lip has quite a dif- 
ferent form, with a deep crimson blotch at its base, and is not half the 
length of the sepals; the middle lobe is rounded not unguiculate, and has 
only a small tubercle in the middle instead of the large concave appen- 
dage that occurs in L. aromatica. 
With regard to the species that belong to true Maxillaria, 
now that it has been weeded of these species, I must take 
another opportunity of examining them. 
21. HEXADESMIA fasciculata. 
Ad. JBrongn. in Ann. des Sciences , xvii. p. 44. 
This plant has flowered in the garden of the Horticultural 
Society, where it has been saved out of a collection formed 
by Mr. Hart weg at Quezaltenango in Guatemala. It has 
small green flowers of no beauty, and the habit of Epiden- 
drum clavatum. 
22. ONCI'DIUM suave. 
0. suave; pseudobulbis ovatis compressis utrinque bicostatis, foliis mem- 
branaceis lineari-oblongis canaliculatis acutissimis, panicula elongata 
ramosa, sepalis petalisque lineari-lanceolatis acutis undulatis revolutis.
