chased at Mr. Skinner's sale, and which, if there is no 

 mistake in the matter, must have come from Guatemala. It 

 is, however, so exactly like specimens found in Popayan by 

 Mr. Hartweg, that we cannot help suspecting some error. 

 Its general appearance may be understood by its having been 

 mistaken for a Trichopilia. Its flowers are produced in loose 

 erect racemes, out of broad obtuse short membranous spotted 

 bracts. The stalks and ovary are an inch and half long ; 

 the latter with three very stout and strong ribs. The sepals 

 and petals are a pale watery green, erect, linear-lanceolate, 

 equal, faintly tinged with purple. The Up is cream-colour, 

 rolled round the column at the base, to which it also is 

 united at the lower end. The column has a singular fringed 

 hood, overlying the anther, and a nearly vertical stigma, 

 closed in by fleshy inflected cheeks. In these circumstances it 

 difi'ers from Aspasia, to which the genus is nearly akin. 

 Mr. Hartweg found in the same country another species, of 

 which and the present the following are the technical cha- 

 racters. 



PiLUMNA, Ovarium tricostatum. Sepala et petala sequalia 

 patula oblique inserta. Labellum basi columnse adnatum, 

 subintegrum, unguiculatum, convolutum, inappendi- 

 culatum. Columna clavata, teres, clinandrio cucullo 

 dentato membranaceo circumdato ; buccis duabus car- 

 nosis semiclausum. Stigma verticale. Pollinia 2, postice 



fissa, caudiculse brevi et glandulse ovatae adnata. 



Herbse epiphytcn, pseudobulbis vaginatis, foliis coriaceis, 



pedunculis radicalibus. Genus Aspasise proximum, 



clinandrio cucullato, columna tereti, nee non stigmate 

 verticali nee faciali diversum. 



Sp. 1. Pilumna laxa ; folio lineari-oblongo, racemo laxo 

 multifloro breviore, bracteis laxis cucuUatis obtusis, 

 sepalis petalisque lineari-lanceolatis, labello oblongo in- 

 diviso rotundato medio constricto per axin unilamellato. 

 In the woods of Timhio near Popayan. 



Sp. 2. Pilumna fragrans ; folio lato oblongo, racemo 2-3- 

 floro breviore, bracteis lanceolatis erectis obtusis, sepalis 

 petalisque oblongo-lanceolatis acuminatis, labello oblongo 



apiculato subtrilobo Isevi. Near the city of Popayan. 



Flowers large, white, sweet-scented, with an orange- 

 coloured spot on the lip, according to Mr. Hartweg.
