34 
rounded angles, has flowered with Messrs. Loddiges, who im- 
ported it from Oaxaca (No. 1265). It is most nearly allied 
to C. filipes, figured in the present number, but differs in the 
form of the lip. 
181, EPIDENDRUM (Encyclium) calocheilum ; pseudo-bulbis ovato-oblongis 
apice diphyllis, foliis ensiformibus obtusis coriaceis obsoleté striatis 
panicula elata multiflora brevioribus, sepalis petalisque lineari-oblongis 
spathulatis uniformibus patentissimis, labello libero suborbiculari pro- 
fundé trilobo basi carinato, lobis lateralibus laté ovatis intermedio latis- 
simo lineato margine undulato crispato, columna superné hinc ala obtusa. 
Hooker in Bot. Reg. t. 3898. 
A Guatemala plant, from the Woburn collection, very 
near Epidendrum altissimum, but apparently distinct. The 
flowers, in a large panicle, are light greenish yellow with the 
sepals and petals tinged with purple at the points, and the lip 
crimson-veined with a yellow border. 
182. PLEUROTHALLIS picta ; folio oblongo coriaceo caule vaginato race- 
moque longiore, spatha diphylla, racemo plurifloro, sepalis reflexis 
inferiore trilineato extus basi villoso duobus superioribus ultra medium 
unitis maculatis, petalis columna longioribus ovato-lanceolatis, labello 
ovato carnoso velutino maculato obtuso intus basi profundeé canaliculato, 
clinandrio dentato, anthera ovarioque pubescenti-tomentosis. Hooker 
in Bot. Reg. t. 3897. 
A Mexican Orchidaceous plant, with purple flowers ar- 
ranged in a spike about one-third the length of the leaf. It 
is very near P. strupifolia and aphthosa (which latter is the P. 
peduncularis of Hooker’s Journal of Botany, vol. 3. t. 9.) but 
apparently distinct from both. 
183. DYCKIA altissima 3 foliis acuminatis recurvo-patentibus distanter 
spinosis glabris, scapi tomentosi (orgyalis) squamis acuminatis integris, 
spica elongata dissitifiora, bracteis acutis sepalis rotundatis brevioribus. 
A native of Buenos Ayres, whence it was sent to the 
Glasgow garden by Mr. Tweedie. It has a flowering stem 
fully six feet high and slender, but the leaves are barely a foot 
long. The flowers resemble those of D. rariflora in colour, but 
are less brilliant. It is a rather pretty greenhouse plant, and 
flowered in the Garden of the Horticultural Society in 
October, 1841.
