columnam convolutis apicibus reflexis ; labelli trilobi lobis lateralibus 

 erectis truncatis, intermedio longiore ovato rotundato deflexo, appendice 

 caniosa linguseformi inter lacinias laterales locata; columna subtus pu- 



bescente Guatemala . Tbe 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 covei'ed with spots and streaks of the most brUliaut 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, coluranse facie villosa. Mexico. The flowers yellowish- 

 orange, scarcely spotted even inside the lip, which has two rows of hairs 

 along its inner face. 

 J 9. L. cruenta (Maxill. cruenta, Lindl. in Bot. Reg. 1842. t. 13.); pedunculis 

 raro bifloris, vaginis distantibus obtusis cucullatis, sepalis ovatis obtusis 

 lateralibus basi pariim 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, Brongn. 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. Hartweg at Quezaltenango in Guatemala. It has 

 small green flowers of no beauty, and the habit of Epiden- 

 drum clavatum. 



22. ONCIDIUM suave. 



^ O. suave; pseudobulbis ovatis compressis utrinque bicostatis, foliis mem- 

 branaceis lineari-oblongis canaliculatis acutissimis, panicula elongata 

 ramosS^, sepalis petalisque lineari-lanceolatis acutis undulatis revolutis.
