entirely destitute of a spur, or, at most, with nothing more 
than a pouch. To the same section belong Dendrobium, 
Stenoglossum, Restrephia, Ornithidium, Telipogon, Brough- 
tonia, Cattleya, Epidendrum, Polystachya, and Cryptar- 
rhena. 
The other Orchideous genera with four cereaceous pollen 
masses, of which Malaxis is the representative, must be re- 
ferred to a section of the Order distinct from Epidendre:e, 
which we shall take another opportunity of defining. This 
section, which may be called MaLAXIDEZ, is formed of 
Prescotia, Microstylis badly defined by Nuttall, Malaxis, 
Liparis, Dienia, Empusa, and, as a separate tribe, of Pe- 
dilea and Stelis. 
Empusa is a most remarkable plant, which can scarcely 
be compared with any known genus. We are acquainted 
with only a single species, for specimens of which from 
Nepal we are indebted to Mr. Lambert. Its character will 
be i 
"EMPUSA. Perianthium sepalis exterioribus lateralibus erectis obliquis 
basi labelli adnatis, czteris linearibus patentibus. Labellum posticum, bi- 
tuberculatum, sagittatum, facie cum basi column: elongate apice alate 
connatà. Pollinia 4 per paria cohzrentia. 
Sp. 1. Empusa paradoxa. 
Herba terrestris, pedalis, radice bulboso. Folia lineari-lanceolata, va- 
ginantia, plicata. Scapus foliis longior. Racemus laxus, floribus patenti- 
bus, bracteis ovario bis torto! pauló brevioribus. 
Hab. in Nepalia (v. s. comm. cel. Lambert). 
The genus Dienia is founded upon plants from Nepal 
with the aspect of Malaxis, to which genus it is probable 
that some of them have already been referred by Sir Jas. 
Smith, in Reess Cyclopzedia. It may be characterized thus: 
DIiENIA. Perianthium explanatum, sepalis linearibus liberis. Zabel- 
lum cucullatum, excavatum, cum columna parallelum. Columna clavata, 
apice alata, Pollinia 4, semiteretia, per paria cohzrentia. 
Sp. 1. Dienia congesta. i 
Folia caulescentia, ovato-lanceolata, petiolis vaginantibus. Scapus foliis 
longior. Spica terminalis, cylindracea, densissima. Flores minutissimi, 
sepalis interioribus filiformibus. 
Hab. in Nepalia (v. s. sp. comm. cel. Lambert). 
Prescotia we have referred to Epidendrez, chiefly on ac- 
count of its habit. In the nature of its pollen masses it 
approaches Mr. Brown's third section of Orchidee, as it 
also does in the structure of its column; but it is in both 
these respects of ambiguous character. 4r
