lines. Mr. Scheidweiler gives the following definition of his 

 new genus. 



Char. gen. Perianthium explanation, sepalis petalisque subeequalibus, sepalo 

 supremo fornicato, labello indiviso oblongo apiculato, disco calloso, cum 

 basi columnar accreto, saccato ; sacculi ore cibis densis cincto ; columna 

 brevis clavata apice auriculata. Anthera unilocularis, pollinia duo, 

 pyriformia, postice sulcata ; caudicula subulata, glandula oblonga. 



123. CATTLEYA Arembergii. 

 Scheidweiler in Gartenzeit. 1843. p. 109. 



C. Arembergii; sepalis lateralibus falcatis obtusiusculis, supremo lanceolate 

 petalis latioribus undulatis, labelli trilobi lobis undulato-crispis, inter- 

 medio margine blacino lamina lutea, lateralibus margine lutescentibus, 

 spatha herbacea compressa obtusa, pseudobulbis cybndraceis nitidis, 

 foliis ovatis carnosis, obsure viridibus. Caulis 8 poll, altus, fol. 4 poll, 

 longa, 2 poll, lata, flores inodori. 



This species, says Mr. Scheidweiler, although having 

 much resemblance to some others, is nevertheless distin- 

 guished by its beautiful dull green ovate leaves, and its great 

 lilac flowers. It is a Brazilian species, and we presume 

 described from Count Aremberg's garden, though that is 

 not stated. 



124. EPIDENDRUM glutinSsum. * 

 Scheidweiler in Gartenzeit. 184<3. p. 1 10. 



E. glutino8um; foliis in pseudobulbos pyriformes tunicatos glabros, binis 

 linearibus coriaceis oblique truncatis, racemo subsimpbei pedicellisque 

 glutinosis, sepalis oblongis acuminatis petalisque spathulatis patentibus, 

 labelli fere liberi trilobi lobis lateralibus oblongis ootusis integris erectis, 

 intermedio ovato crispato, disco calloso depresso, columna bidentata. — 

 Scapus terminalis pedalis, petala et sepal a viridi-purpurea, extus lineis 

 purpureis notata, labellum albo-lutescens, lobo intermedio lineis purpu- 

 reis ornato. 



This plant, which comes from the neighbourhood of 

 Rio Janeiro, and is remarkable for the glutinous condition of 

 its scape and peduncles is, according to Mr. Scheidweiler, 

 very near Epidendrum odoratissimum, which he considers 

 identical with the Encyclia patens of Hooker and Macradenia 

 lutescens of Loddiges. Its scape is a foot high. The petals 

 and sepals are greenish purple, marked outside with purple 

 lines. The lip is whitish yellow, its middle lobe being 

 marked with purple lines.
