vies with the other in loveliness. One of them, Burlingtonia venusta, 
a native of Brazil, may be literally said to sink beneath its long heavy 
clusters of snow-white blossoms just tinged with I a second, seated 
upon the highest branches of the Cedrela tree, perfumes the forests of the 
same country with the odour of Jonquils: it is Burlingtonia fragrans ; 
while a third, Burlingtonia rubescens, delicately spotted with rose 
colour, inhabits the trunks of the Calabash tree in the mission of Yurima- 
guas, in the province of Maynas, the hottest part of Peru, and is loaded 
with blossoms all the year long ; and the fourth, Burlingtonia rigida, with 
many peculiarities, to which I shall immediately advert, breathes the 
delicious fragrance of the violet. 
Atthe end of the column of Burlingtonia fragrans there are two little 
brownish purple teeth, which are probably rudiments of anthers; even 
in Burlingtonia venusta there is a trace of them, but a less distinct one. 
These bodies, in Burlingtonia rigida become long purple ears, fringed 
with gland-like hairs, and standing erect like a pair of curved pen-knife 
blades. Nothing indeed is more common throughout the whole of the 
order than such rudimentary stamens in one state or other. In Zygostates 
they attain their greatest degree of developement, separating from the 
column to the very base, and spreading away from it at a right angle. 
One species of the latter genus exists in Dr. von Martius's Brazilian 
Herbarium; the other 1 find among M. Descourtilz's drawings. 
Characters of the four additional species of Burlingtonia, and of the 
last mentioned genus, are given below. 
Burlingtonia venusta; racemis pendulis, sepalo anteriore integerrimo supremo acuto; 
labello infra medium tranversè plicato.——Brazil ; Descourtilz's drawings, No. 83. 
Burlingtonia fragrans; racemis erectis, sepalo anteriore integerrimo supremo acuto, 
labello postico cucullato supra unguem bilamellato disco pubescente elevato apice tri- 
dentato.——-Brazil, in the districts of Morro-Quemado and Macahé, and in the neigh- 
bourhood of the town of Bom Jesus de Bananal ; Descourtilz's drawings, No. 12. 
Burlingtonia rubescens ; racemis erectis, sepalo anteriore integerrimo lineari-lanceolato 
patente supremoque acuminatis, labello basi auriculato bilamellato. —— Peru; 
Pöppig (nov. gen. et sp. vol. 1. p. 41. t. 70 Rodriguezia Batemanni). 
Burlingtonia ; caulibus teretibus rigidis durissimis erectis per longa intervalla pro- 
liferis, pseudobulbis obovatis compressis monophyllis, foliis oblongis, scapo longo 
rigido apice raeemoso, labello basi mutico disco sparsè lamellato, columnà pubes- 
cente apice appendicibus 2 falcatis ereetis pilosis auritá. Found in Brazil, near 
Villa Nova de Almeida, by Prince Maximilian of Wied Neuwied, and preserved in 
the Brazilian Herbarium of Dr. Von Martins.——This singular plant has stiff, appa- 
rently erect stems, the thickness of a erow's quill, which throw out pseudo-bulbs 
at intervals of from 1} to 2 feet, each pseudo-bulb pushes forth its own roots, which 
are extremely long and as fine as hairs; and gives birth to a scape of the same thick- 
ness and texture as the main stem, a foot and half long, at the tip of whieh are 
clustered 5 or 6 flowers, the size of those of Burlingtonia nivea, with the perfume of 
violets. I believe Messrs. Loddiges possess living plants of this. 
ZYGOSTATES. Sepala membranacea, libera, reflexa, Petala dilatata fimbriata, sepalis 
multó majora, patula. Labellum cymbiforme, membranaceum, patens, basi intus 
cornutum aut dentatum, cum columna articulatam. Columna teres, antieċ exca- 
vata, basi utrinque brachio aucta lineari, apice globoso, sepalis equali, patentissimo 
(stamine sterili). Rostellum longissimum, subulatum, arcuatum. Anthera rostrata, 
unilocularis. Pollinia 2, caudiculà subulatà, glandulà minimá.——Herbw epi- 
phyte, acaules, Brazilienses, racemis pendu/is, floribus parvis viridi-luteis. : 
ki Zygostates cornuta; cornu unico incurvo ad basin labelli, petalis rhomboideis.—— 
Brazil, Prince Maximilian of Wied Neuwied. 
2. Zygostates lunata; dente duplici ad basin labelli, petalis lunatis ——On trees on the 
highest wooded mountains of the district of Bananal in Brazil, in the midst of 
dense cold fogs, which are almost perpetual, flowering in March ; Descourtilz's draw- 
ings, No, 4.——Sepals whitish. Petals greenish yellow.
