THE SPECKLED PERISTERIA. 
PERISTERIA. Sepala subaequilonga, lata, crassiuscula, in globum conniventia, lateralia postico latiora et 
basi breviter connata. Petala sepalis minora, caeterum subsimilia. Labellum carnosum, cum pede columnae conti¬ 
nuum, basi patens ; lobi latérales lati, erecti; médius articulatus, indivisus, basi incumbens, margine et apice 
recurvis; discus saepe callosus. Columna erecta, subincurva, brevis, crassa, exalata, antice biauriculata vel nuda, 
basi in pedem producta; clinandrium obliquum, postice elevatum. Anthera terminalis, opercularis, incumbens, imper- 
fecte bilocularis; pollinia 2, cerea, angusta, oblonga, saepius sulcata vel subdivisa, inappendiculata, anthera déhis¬ 
cente glandula oblonga cuneata vel lata affixa. 
Herbae epiphyticae, validae, caulibus brevissimis vaginatis mox in pseudobulbum carnosum apice uni-vel pauci- 
foliatum incrassatis. Folia ampla nunc longissima, plicato-venosa, in petiolum contracta. Scapi ad latera pseudo- 
bulborum erecti nutantes vel a basi deflexi, simplices. Flores speciosi, in racemo brevi vel elongato breviter pedicellati. 
Bracteae parvae vel membranaceae at ovario breviores. 
Species circa 8, Andium Columbiae incolae.

his interesting Peristeria was collected by the intrepid collector M. Bun- 
geroth, on the declivities of the Sierra de Marawaca, one of the most 
elevated mountains of the Parama chain, in Venezuela, and flowered 
in the collection of L’Horticulture Internationale, Parc Léopold, Brussels, 
during last summer. It is closely allied to the rare P. Rossiana , Rchb. f., known 
to me by an excellent example sent by Signor H. J. Ross, of Florence, Italy, 
from the type plant. Both hâve a strong transverse keel-like ridge behind, 
connecting the transverse plates of the side-lobes, but in P. Rossiana there is 
a second smaller ridge connecting the front edges of the said transverse plates 
of which I cannot detect a trace in P. aspersa. This, taken in conjunction with 
a number of minor différences, seems to show that they are quite distinct 
species. Indeed the pendulous-flowered species of the genus bear such a strong 
external resemblance to each other that careful examination is often necessary 
in order to distinguish them. 
The flowers of P. aspersa are borne in short racemes, ten being présent in 
the specimen now before me. The colour is a light brownish-yellow, densely
