[Illustration: PL. 130. THUNIA MARSHALLIANA.] THUNIA MARSHALLIANA. [Plate 130.] Native of Moulmein. Terrestrial. _Stems_ reed-like, erect, glabrous, cylindrical, about two and a half feet high, becoming smaller upwards, swelling into roundish tuberous knobs beneath the soil, clothed above with distichous leaves, and terminating in a dense raceme of flowers. _Leaves_ oblong-lanceolate, acuminate, semi-amplectant, about six inches long, five to seven nerved, of a pale green colour, glaucous beneath. _Racemes_ terminal, nodding, dense, and many-flowered, the bracts large ovate-lanceolate, acute, concave, shorter than the ovaries, pale yellowish green. _Flowers_ large and delicately beautiful, white with orange-red veins; _sepals_ and _petals_ lanceolate-oblong acute, spreading, nearly equal, about two and a half inches long, pure white; _lip_ white, with the lower part convolute around the column, produced behind into a retuse falcate spur and having in the centre five veins or ribs, fringed at the edge; the front part or limb flattened out, roundish, yellow with numerous forking veins of a deep orange-red colour, occupying the whole area, the disk traversed by five yellow raised veins, and about five shorter ones on each side, all pectinately fringed with crystalline hairs, the margin toothed and beautifully crisped, the extreme edge being white. _Column_ enclosed by the lateral lobes of the lip (which are yellowish striated with red near the front) terete below, widened above, with two prominent toothed wings near the tip forming a kind of hood. Thunia Marshalliana, _Reichenbach fil._, _Linnæa_ xli., 65; _Regel_, _Gartenflora_, t. 1098. The _Thunias_ form a small genus of very beautiful Orchids, which have the further recommendation of being easy of cultivation. They are deciduous in habit, losing their stems and leaves after they have bloomed and completed their growth. That which we now figure, _T. Marshalliana_, is a most distinct and showy species. Our sketch of which was taken from a well grown plant belonging to W. Cobb, Esq., Silverdale Lodge, Sydenham, who has a well selected and finely grown collection of Orchids. This plant was indeed a marvel of cultivation, and did great credit to Mr. Catt, the gardener.
