ceous plants, founded on a specimen that has flowered in the 
Garden of Plants, and which he calls Houlletia, assigning it 
the following character :— 
Perianthium membranaceum patens (non reflexum). Sepala concava 
libera, inferioribus vix basi column connatis. Petala basi angustata, 
unguiculata, apice rotundata. Labellum cum basi incurvaté columne 
articulatum, liberum, carnosum, medio constrictum articulatum, parte 
basilari (hypochilio) oblonga plana, lobis seu processubus lateralibus 
membranaceis angustis retrorstim arcuatis eorniformibus, parte apicilari 
(epichilio) infra basilarem articulaté integré.—Columna perianthio bre- 
Vior arcuata semi-teres, antice plana, vix superne alato-marginata. Stig- 
ma transyersé excavatum. Anthera opercularis depressa; pollinia duo 
oblonga angusta, externé sulcata, caudicula membranaced oblonga basi 
connata, glandula angusta lanceolata. 
Epiphyta, pseudo-bulbis ovato-conicis, monophyllis, foliis longissime petio- 
latis, plicatis, membranaceis, scapo radicali ascendente, floribus racemo- 
sis nutantibus, ovario plus minusve contorto, perianthio membranaceo 
pallidé maculato, fragrante, labello carnoso maculis atro-violaceis in- 
sperso, leevem odorem stercoreum olente. 
He considers it near Stanhopea, from which it differs in 
its sepals not being reflexed, its lip articulated in the middle, 
the lower half bearing two membranous horns directed back- 
wards and upwards towards the column, by the column being 
short and not membranous at the edge, by the petals having 
a stalk, by the lanceolate form of the gland of the pollen- 
masses, and by the flowering stem being erect, not pendulous. 
Upon considering this character it is evident that Houlletia 
is either the same as Maxillaria? Brocklehurstiana, already 
mentioned in this volume, p. 10. no. 28, or a plant very 
nearly related to it. As the genus is no doubt a good one, it 
will be necessary to change the name of my species to Houl- 
letia Brocklehurstiana. At the same time I have a new 
species to add. 
100. HOULLETIA vittata ; sepalis linearibus acutis, petalis lineari-lanceo- 
latis basi tortis, hypochilii lobis ovatis obtusis rectis, epichilio rhombeo 
apice rotundato angulis lateralibus acutis. 
This very curious plant was received by Messrs. Lod- 
diges from Mr. Schomburgk. It has the erect raceme of 
Houlletia Brocklehurstiana, but the flowers are much smaller, 
form a pyramidal mass, and are yellow, streaked with so 
much deep chocolate colour that the former is hardly seen 
except on the lip. From the similarity in habit between 
these plants and Maxillaria Warreana one would have thought
