2. MAXILLARIA foveata ; foliis lanceolatis undulatis plicatis racemo triplò 
longioribus, bracteis linearibus sphacelatis ovario longioribus, sepalis peta- 
lisque lineari-oblongis obtusiusculis, labello postico oblongo apice trilobo : 
laciniá mediá rotundatá carnosá excavatá, disco ter aut quinquies sulcato. 
A new species from Demerara, for which I am obliged 
to Messrs. Loddiges. It is very near M. squalens, but has a 
different lip, and its flowers are of a pale uniform dull straw 
colour. They have a faint, and not unpleasant, smell. 
3. PLEUROTHALLIS strupifolia ; folio longissimo coriaceo obtuso lorato 
plano, racemis brevibus fasciculatis pendulis, floribus hiantibus pubescenti- 
bus, sepalo intermedio oblongo apice carnoso revoluto lateralibus semicon- 
natis majoribus porrectis intús maculis pilosis (!) notatis, petalis rhombeo- 
linearibus acutis, labello oblongo obtuso concavo nudo. 
This is the most remarkable species of the genus I have 
yetseen. Its leaves are like leather thongs, and full eighteen 
inches long. The flowers are dull purple and white, with 
patches of short deep purple hairs on the inside of the lower 
sepals. It was imported from Rio by Messrs. Loddiges. 
4. LALIA albida 3 pseudo-bulbis ovalibus diphyllis, foliis linearibus acutis 
spicá multiflora 4-pld brevioribus, sepalis oblongo-lanceolatis acutis vel sub- 
acuminatis petalisque latioribus acutis, omnibus apicibus reflexis fortiter 
mucronulatis ; labelli alte trilobi, tricostati lobis lateralibus erectis rotundatis 
intermedio duplo majore subrotundo obscure apiculato reflexo. Bateman

* A native of the environs of Oaxaca, whence it was 
sent to me this spring by the Messrs. Sadler of that place. 
Its colour is quite a novelty in the genus, all the other 
species bearing rose-coloured or lilac flowers. [t has the 
graceful appearance of L. autumnalis, from which it can 
scarcely be distinguished in habit. [ts flowers are ver 
different in their form (as well as colour) from all the other 
species; they are about two inches across, sweet-scented, and 
excepting a bright yellow streak down the centre of the lip, 
and a few crimson dots at its base, are of a uniform semi- 
transparent white. It appears to be of easy cultivation, and 
the most free flowering individual of the genus." The fore- 
going memorandum has been communicated to me by Mr. 
Bateman. I have also received the plant from Mr. Harris. 
It will be figured hereafter in this work.
