CALANTHE viridi-fusca; pseudobulbis oblique lato-ovatis lobato-sulcatis, folio 
solitario lanceolato acuminato striato basi longe vaginato, scapo radicali 
glabro, spica elongata laxa multiflora, sepalis petalisque (viridi-fuscis) lan- 
ceolatis, labello erecto oblongo subspathulato columnam amplectente 3-lobo 
lobis lateralibus brevibus obtusis intermedio lato semiorbiculari mucronato, 
disco longitudinaliter lamellato maculato, calcare brevi obtuso incurvo. 
A native of Assam, whence it was sent to the Royal Gardens 
of Kew by Mr. Simon. It flowered with us in April, 1852; 
and is remarkable among known species of Calanthe for the 
erect or nearly closed sepals and petals, the peculiar form of the 
lip, and the colour of the flowers. We presume it to be ter- 
restrial. The habit approaches that of Calanthe Masuca more 
than any other species. : 
Dzscr. The pseudo-bulh is broad-ovate, spreading out most 
on one side, dark green, firm, at the base furrowed and lobed, 
the upper part more or less covered with the remains of the 
long sheathing scales of the preceding year’s leaf. Leaf solitary, 
arising from an infant inconspicuous pseudo-bulb, a foot or 
more long, lanceolate, membranaceous, plicato-striate, much and 
gradually acuminated at the point, the base tapering into a very 
long petiole, which is sheathed by three or four, long, cylindrical 
scales. Scape (including the long lax spike) a foot and a half 
long, terete, glabrous, erect, arising from the base of a pseudo-— a 
bulb bearing brown, striated, sheathing, membranous bracteas, 
especially at the base. Spike many-flowered, bracteated ; drac- 
teas subulate, green, one under each ovary, and shorter than it. 
Ovary slender, clavate. Flowers greenish-brown, moderately
