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). Scpala concava 

 libera, inferioribus vix basi columnar connatis. Petala basi angustata, 

 unguiculata, apice rotundata. Labellum cum basi incurvata coluninse 

 articulatum, bberum, carnosum, medio constrictum articulatum, parte 

 basilari (hypochilio) oblonga, plana, lobis seu processubus lateralibus 

 membranaceis angustis retrorsum arcuatis corniformibus, parte apicilari 

 (epichilio) infra basilarem articulata, integra,.— Columna periantbio bre- 

 vior arcuata semi-teres, antice plana, vix superne alato-marginata. Stig- 

 ma transversa excavatum. Antbera opercularis depressa ; pollinia duo 

 oblonga augusta, externe sulcata, caudicula membranacea, oblonga basi 

 connata, glandula angusta lanceolata. 



Epiphyta, pseudo-bulbis ovato-conicis, monophyllis, foliis longissime petio- 

 latis, plicatis, membranaceis, scapo l'adicali ascendente, floribus racemo- 

 sis nutantibus, ovario plus minusve contorto, periantbio membranaceo 

 pallide maculato, fragrant e, labello carnoso maculis atro-violaceis in- 

 sperso, lsevem 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. 



lt)0. HOULLETIA vittata; sepalis linearibus acutis, petalis lineari-lanceo- 

 latis basi tortis, hypocbilii lobis ovatis obtusis rectis, epichilio rbombeo 

 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 Avith 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
