Epiphytal. _Stems_ short, clavate, with a thickened bulbiform base, jointed, deeply furrowed, the internodes almost wholly covered by membranaceous sheaths, bearing leaves at the apex. _Leaves_ two or four, lanceolate, ovate, coriaceous, dark shining green. _Racemes_ many-flowered, drooping, lateral, proceeding from near the top of the stem, just beneath the leaves, the pale green pedicels with a small concave ovate bract at their base. _Flowers_ bright golden yellow, showy; _sepals_ oblong-ovate, bluntish, spreading, of a clear bright golden yellow; _petals_ of the some colour, much broader, roundish-ovate, almost meeting at the edges; _lip_ concave, roundish, subunguiculate, with a small blunt spur behind, pubescent on the upper surface, and denticulate at the edge, of a deep rich orange-yellow, which contrasts agreeably with the lighter and brighter yellow of the outer perianth segments. _Column_ small, pale yellow. Dendrobium Farmerii aureum, _supra_. Here we have a most charming Orchid, and one that blooms very freely on short bulbs or stems. The plant is of less vigorous habit than certain other of the varieties of _D. Farmerii_, some of which grow as vigorously as _D. densiflorum_. Indeed, excepting by cultivators who are well acquainted with the plants, it is a most difficult matter to distinguish them readily from each other. The plant we now describe and illustrate is a yellow-flowered variety of _D. Farmerii_, the typical form of which has pinkish sepals and petals and a rich yellow lip. It is a very lovely species. Our drawing of this rare variety was taken from a plant in the Victoria Nursery, Upper Holloway, where we have had the different forms flowering during the months of May and June, many of them growing on a back wall on blocks of wood, and producing a fine effect with their spikes of yellow blossoms hanging over the foliage. Even when grown in pots or baskets they have a pleasing effect, and take but little space. _Dendrobium Farmerii aureum_ is a compact evergreen species from Moulmein. It grows about ten inches high, with dark green shining foliage. The flower spikes proceed from the top of the old bulb stems, and are sometimes ten inches in length. The sepals and petals are bright golden yellow, and the lip rich orange. The plant blooms during March, April, and May, and lasts about a fortnight in perfection.
