This species has been long known, but it was slow in making its appearance, and slow likewise in flowering after it had reached us. During the last four years both Messrs. Veitch and M. Linden have succeeded in importing it alive, but it has only produced flowers in two or three instances; the finest specimens I have seen being those exhibited by Lord Londesborough during the present spring (1874). Even in its native country it seems to be a shy flowerer. As it is never met with lower than 7000 feet on the mountains of Pamplona, it of course requires a cooler treatment than many of its congeners which affect a lower level. The shining surface of the sepals and petals is very remarkable, and has the appearance of being due to a coat of the best varnish. Another species, _O. brevifolium_, found in lofty mountains in Peru, is closely allied to this, if indeed, which I greatly doubt, it be anything more than a very high-level variety of it.
O. (EUODONTOGLOSSUM) pseudobulbis ovatis 1-2-phyllis, foliis lineari-lanceolatis acutis racemis multifloris subæqualibus, sepalis petalisque cuneato-lanceis acuminatis; labelli ungue bilamellato, lamellis oblongis antice obtusangulis, laminâ ab ungue cuneato velutino ampliato ovatâ acuminatâ crispulâ, cornubus brevibus geminis ante lamellas, antepositis falcibus geminis, tumore parvo interjecto; cirrhis columnæ basi angulatæ bifidis setaceis.
ODONTOGLOSSUM BLANDUM, _Rchb. fil. in Gardeners' Chronicle_, p. 1342 (1872).
PLANT _about a span across, in a compact mass_.
PSEUDOBULBS _ovate, somewhat compressed, about an inch long, bearing 1 (rarely 2) narrow lanceolate_ LEAVES _of about the same length as the slender nodding many-flowered_ RACEMES. _The_ FLOWERS, _of which there are from six to twelve (or more) crowded together on the racemes, are all expanded at the same time, and emit a pleasant honey-like smell_. SEPALS _and_ PETALS _nearly equal, less than an inch long, lanceolate, acuminate, of a creamy white sprinkled over with numerous crimson dots_. LIP _about the same length as the sepals, and of the same hue, but destitute of spots except at the apex, the central portion bearing a large crimson mark nearly in the form of the letter_ W; _the lip's base is formed of two parallel blunt lamellæ out of which springs the main limb which is broadly ovate, curled and jagged at the edges and recurved and acuminate at its extremity; at the point of junction with the unguis or claw occur two horned falcate processes, between which a small tumour is interposed, at foot of which are two short and blunt horns_. COLUMN _short, bifid, angular with three or four straggling cirrhi or filaments on either side_.
