A. Nelsoniana (n. sp.) (After the Right Honourable Sir Hugh M. Nelson, 
K.C.M.G.) | Pseudobulbs about 2 in. high, arising from a mass of erect 
whitish roots, fluted, and bearing at the summit usually - linear leaves varying 
from 4 to 8 in. in length, with a breadth of less than 1 in., plicate and sharply 
keeled, apex bluntly pointed. Scapes from base of pseudobulb erect, 2 feet 
high, branched in the upper part, the branches ending in racemes of small 
pretty flowers; bracts lanceolate, small,and numerous. The whole inflorescence 
slender and wiry. Pedicels with ovary 4 lines long; sepals and petals linear, 
about 3 lines long and 3-line broad, yellowish with a green tinge. Labellum 
white, the lower part adnate to the sides of the base of the column, the upper 
portion deeply 3-lobed; lobes obtuse, the middle one bearing upon its disk 2 
erect prominent plates. Column with a projecting stipitate gland-like process 
on either side of the stigma. Rostellum gland-like. Anther-lid membranous, 
completely covered by a hood formed by an elongation of the apex of the 
column. Pollen-masses 2, clavate on rather long filiform caudicles, the gland 
to which they are attached being rather prominent.

C. Lamingtonii (n. sp.) (After His Excellency the Right Honourable Lord 
Lamington, K.C.M.G.) Plant of somewhat straggling habit, the erect stems 
attaining 6 or 7 ft, often slightly spirally twisted; the whole plant, with the 
exception of the seed and parts of the flower, velvety-pubescent. Leaves 
oblong-lanceolate, 6 to 12 in. long; lateral nerves erecto-patent from the midrib, 
parallel and rather close ; sheath closely clasping the stem, petiole above the 
sheath and ligula, about 2 or 3 lines long. Inflorescence a terminal 
oblong spike usually about 4 in. long, of a deep rusty-red colour; flowers 
white. Bracts: Outer—broad-lanceolate, 1 in. long, velvety outside, the inside 
striate ; inner—linear, obtuse, } in. Calyx-tube 4-in. long, 3-toothed at the 
top, 3-angular, inside striate. Corolla-tube 3-in. long, bearing inside near the 
orifice numerous yellow clavate glands; upper erect lobes 3, glabrous, oblong, 
membranous, 14 in. long. Labellum about 2 in. long, the sides incurved 
forming a tube with a broad wavy mouth, velvety on both sides, disk stained 
with yellow. Filament broad, produced beyond the anther, the end sometimes 
torn or lobed. Style slender semiterete in the upper part, where it lies 
between the anther-cells, expanding about the stigma. Capsule almost 8- 
winged, crowned by the persistent calyx, about 6 or 7 lines long, opening 
loculicidally in 3 slits. Seeds shining black, numerous in each cell. 
Hab : Mambare River, New Guinea. 
TAPEINOCHEILOS, Mig. 
T. pungens, Wiz. Stems leafy, 5 or 6 ft. high, below the inflorescence, close 
under which long curved leafy branches are emitted. Leaves 6 to 8 in. 
long, lanceolate with long narrow points, set on the branches spirally, con- 
tracted into a short petiole above the long sheathing base; spike very dense, 
6 to 12 in. long and 2 or 3 broad, yellowish. Bracts not so pungent as in 
the Queensland plant. Calyx forming a horny shortly 3-lobed tube above the 
ovary. Corolla horny-lobed lower down than the calyx. Filataents broad, 
petaloid ; the 2 anthers attached by their base only, the upper portion of the 
broad filament forming a hood over them. Style narrow, expanding at the 
top, and forming a broad hairy indusium about the stigma.
