180 BOTANY OF THE VOYAGE OF THE SULPHUR. 
Cuar. Gen. Perigonium longe tubulosum, limbo 5-fido, laciniis zstivatione imbricatis. 
Squame ad faucem 5, laciniis alternze. Stamina 10, 5 ad faucem laciniis perigonii opposita, 5 paullo 
inferius inserta, squamis opposita; filamenta brevia; anthere lineares, versatiles, biloculares, loculis 
longitudinaliter dehiscentibus. Vagina brevis, ovarii basin cingens. Ovarium biloculare, ovulis in 
quoque loculo solitariis, ab apice anguli interioris pendulis. Stylus longus, filiformis, apice incras- 
satus in stigma oblongum leviter emarginatum. Drupz sarcocarpium tenue, putamen crassum 
lignosum biloculare dispermum. Semina pendula, exalbuminosa, cotyledonibus crassis, radicula 
brevissima supera. 
S. Burnettiana. Frutex (vel arbor?) glaberrimus. Folia opposita, exstipulata, breviter petiolata ovato- 
elliptica vel suprema fere orbicularia, brevissime acuminata, integerrima, subcoriacea, nitidula, penninervia, 
reticulato-venosa, 24-34 poll. longa. Flores in capitulo terminali breviter pedunculato circa 10, sessiles. 
Involucrum in speciminibus nullum, sed cicatrices supersunt bractearum vel deciduarum, vel abortientium. 
Perigonium gracile, basi et apice leviter ampliatum, extus glabrum, bipollicare; laciniee limbi crass, oblong, 
obtuse, concave, 3-4 lin. longs, in alabastro valde imbricate ; tubus intus hirsutus. Squamee faucis parve, 
ovate, vagina brevissima, glabra, integra. Ovarium oblongum, leviter compressum, villosum. Drupa magni- 
tudine nucis avellane, compresso-globosa, siccitate rugosa, et interdum subdidyma, putamine crassissimo lignoso- 
fibroso. Seminum testa nigro-fusca. (Benth. 1. c. pp. 231, 282.) 
At the request of Mr. Hinds, I dedicated this species to Sir William Burnett, 
Inspector-General of the Navy, a zealous promoter of natural history, and much 
respected by the medical officers of the navy; regretting, at the same time, that a 
genus existing already of the name of Burnettia, precluded my fulfilling entirely 
the wishes of Mr. Hinds, to dedicate one to Sir William.

Denprosium bifalce, Lindl. sp. n., (Plate LVIII.) caule tereti levigato, folio (solitario ?) coriaceo 
obovato acuto oblique emarginato, pedunculis longissimis rigidis nudis apice paucifloris, pedicellis 
racemosis erectis floribus triplo longioribus, petalis lanceolatis trinerviis membranaceis labello ungui- 
culato tripartito supra unguem crista duplici carnosa biloba undulata aucto, laciniis lateralibus 
linearibus obtusis falcatis intermedia subrotunda, cornu obtuso incurvo. 
This very singular plant exists in an imperfect state in the collection. Its 
habit is different from that of any Dendrobium I am acquainted with; but since 
this genus presents great diversity of habit, I cannot attach importance to that 
circumstance, in the absence of a more complete knowledge of the structure of the 
fructification. In my solitary specimen the main stem is gone, and I have only a 
couple of rigid peduncles proceeding from a common point, with a surface like 
that of a small bamboo, and a foot and a half long. With them, but separate 
from them, is a remarkably coriaceous leaf, six inches long and two inches broad 
at the broadest part, but how it fits on the stem there is no evidence to show. 
The flowers are inserted in a few-flowered raceme at the end of the peduncles ; 
they appear to have been purple and some pale colour, and are about as large as 
: those of Aporum anceps. At the base of the middle lobe of the lip are two parallel
