the Botanic Garden at Rio, with the information, that it 
was one of two specimens that had recently been dis- 
covered in the Organ Mountains. In August of the same 
year, its lovely flowers were displayed, when the drawing 
here represented was made on the spot. Widely as the in- 
florescence differs in size and colour from Dr. Linprey’s C. 
guttata above quoted, it cannot be considered otherwise 
than as a beautiful and stately variety, worthy of a place in 
every choice collection of epiphytes. 
Descr. Stems clustered, three feet high, erect, but with 
a graceful curve, rounded and striated, jointed, about as 
thick as one’s finger, of asilvery greenish-white, with green 
blotches. Leaves two from the top of the stem, large, six 
inches and more long, spreading, fleshy, oblong-oval, or 
elliptical, scarcely striated, somewhat concave. From be- 
tween the leaves springs a short spatha, whence arises the 
peduncle, which is short, bearmg a raceme of about five 
handsome, spreading flowers, each about five inches across. 
Sepals oblong-lanceolate, obtuse ; petals similar to them, 
but waved at the margin ; all of them of a rich greenish- _ 
brown colour spotied with purple. Zp short for a species” 
of the present Genus ; the side-lobes a delicate rose colour, 
the intermediate one, which is broadly wedge-shaped, red- 
purple, with deeper lines. Colwmn scarcely longer than the 
side lobes of the lip. 
Guiapiotus Mortonius. (t. 3680.) 
Mr. Herserr further observes, with regard to this species, that it 
always blows in the winter, and rests in the spring. G. oppositiflorus 
flowers very late, viz., at this season (Sept.), but Mortonius shows no 
signs of flowering yet.
