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 Malavis is the representative, must be re- 
ferred to a section of the Order distinct from Epidendrez, 
which we shall take another opportunity of defining. This 
section, which may be called Maraxipeam, is formed of 
Prescotia, Microstylis badly defined by Nuttall, Malazis, — 
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, Be 
' Empvusa. Perianthium sepalis exterioribus lateralibus erectis obliquis 
basi labelli adnatis, czteris linearibus patentibus. Labellum posticum, bi- 
tuberculatum, sagittatum, facie cum basi columne elongate apice alate 
connataé. Pollinia 4 per paria cohgrentia. ” . 
Sp. 1. Empusa paradoxa. 
__ Herba terrestris, pedalis, radice bulboso. lia lineari-lanceolata, va- 
ginantia, plicata. Scapus foliis longior. acemus laxus, floribus patenti- 
bus, bracteis ovario bis torto! pauld 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 Rees’s Cyclopedia. It may be characterized thus: 
DieniA. Perianthium explanatum, sepalis linearibus liberis. Label- 
lum cucullatum, excavatum, cum columna parallelum. Columna clavata, 
apice alata. Pollinia 4, semiteretia, per paria cohzrentia. 
Sp. 1. Dienia congesta. 
_ Folia caulescentia, ovato-lanceolata, petiolis yaginantibus. Scapus foliis 
longior. (Spica terminalis, cylindracea, densissima. lores 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. ae
