stance, from a groove in the base of the leaf, arising from 
one or more filamentous or fibrous bractexw, scaly with 
bracteez below, bearing flowers for the rest of their length, 
which are distichous, erect, each with a sheathing short 
bractea at its base. Calyx of three erect, nearly equal and 
connivent, thick and coriaceo-carnose, obtuse, pieces or 
leaves, quite surrounding and concealing the rest of the 
flower, downy and pale brownish-green externally, within 
minutely tubercled and richly spotted and lined with brown, 
of these the two lateral or lower ones are combined for half 
their length. Petals exceedingly minute, erect, pale-green, 
spathulate, acute, serrated at the point and crested. Lip 
scarcely larger than the petals, quite erect, ovato-oblong, 
greenish-purple, with two large tubercles near the middle. 
Column erect, smaller than the lip, semicylindrical, dilated, 
concave and serrated at the top and there somewhat winged, 
including the stigma and operculiform anther, which is 
yellow, and contains two hemispherical, yellow, waxy 
pollen-masses, united at their bases by a small gland. 
Germen clavate, furrowed, short, straight. 
Brazil is still sending forth new contributions to our 
vegetable treasures; and among the Orchideous tribes her 
productions rank pre-eminent. Many of great interest are 
communicated to the rich collection of Mrs. ArnoLp 
Harrison of Aigburgh, by her brother W. Harrison, Esq. 
long a resident in that country; and among them is the 
present interesting species, which Mr. Loppices from speci- 
mens sent to him by Mr. F. Warre from the same part of 
the world, has published in his Bot. Cabinet, under the ap- 
propriate name of PLeurorHauis saurocephalus, It is 
unquestionably nearly allied to the P. proliferus of Mr. 
Herszerr in Bot. Register, t. 1298: but it differs in its stem, 
leaf, and in the shape and colour of the calyx. 
__P. saurocephalus flowered in Mrs. Harrison’s collection, 
in the stove, during the month of May, 1830.
