Part 13

O. triumphans does not appear to be so plentiful in its native habitats as O. Hallii, O. luteo-purpureum, and many other N. Grenada kinds that now swarm in our collections. The range of elevation within which it grows is nearly identical with that of O. Hallii, hence the same treatment is suitable to both. It is easily grown and flowers freely.

KRAMER'S ODONTOGLOSSUM.

O. pseudobulbis suborbicularibus valde compressis ancipitibus 1-phyllis, foliis oblongo-lanceolatis, scapis ascendentibus vel sub-pendulis foliis brevioribus pauci-(2-5) floris, sepalis petalisque oblongis acutis subæqualibus, labelli ungue 2-calloso laminâ subquadratâ 2-lobâ pallide-roseo-violaceâ plagâ basi utrinque semilunari albâ aureo et purpureo maculatâ.

Habitat in COSTA-RICA.

DESCRIPTION.

PSEUDOBULBS nearly round, flattened, 2-edged, 1-leaved; LEAVES oblong-lanceolate, leas than a foot long, by about an inch wide, longer than the SCAPES which bear from 2 to 5 flowers. PEDUNCLES with the ovary one to one and a half inches long. FLOWERS one to one and a half inches in diameter. SEPALS and PETALS subequal oblong-acute, pale violet-red in the centre with broad white margins. LIP one-third of an inch wide, neck short, broad, deeply hollowed in front with two erect calli; limb subquadrate, two-lobed at the apex, angles rounded, the basal lateral lobes small, reflexed, pale violet-red with two confluent semilunar white patches at the base, on each of which is a concentric red-brown band, and a few spots of the same colour on a golden yellow ground. COLUMN short, thick, without wings or appendages. (Hooker, l. c.)

This though not a striking is a very distinct plant. It is a native of Costa-Rica, where it seems to be plentiful enough though it long eluded detection. It was first exhibited in 1868 by Mr. Veitch at one of the shows at S. Kensington, but appeared almost simultaneously in the collection of Mr. Day, by whose direction a careful drawing was prepared. Like other Costa-Rica plants, though not requiring a high temperature, it is scarcely content with the small amount of heat that is now allotted to the great majority of cool Orchids. Its proper place would be in the Mexican House. It is a free bloomer.

ODONTOGLOSSUM CORDATUM.

HEART-LIPPED ODONTOGLOSSUM.

O. (EUODONTOGLOSSUM) pseudobulbis oblongis compressis monophyllis, foliis lato-oblongis planis acutis scapo squamis carinatis vaginato brevioribus, racemo simplici vel paniculato, bracteis navicularibus acuminatis membranaceis, ovario multo brevioribus, sepalis petalisque lineari-lanceolatis acuminatissimis, labello cordato acuminatissimo integerrimo, appendice unguis carnosâ apice bilobâ basi utrinque dente unico auctâ, columnâ pubescente clavatâ subapterâ.

Habitat in MEXICO, Barker. GUATEMALA, Hartweg, Skinner.

DESCRIPTION.

PSEUDOBULBS oblong, very much compressed and very sharp at the edges, 1½ to 2 inches long. LEAVES one (rarely if ever two) on each pseudobulb and broadly-oblong acute shorter than the scape. SCAPE and RACEME sheathed at intervals with long keel-shaped membranaceous BRACTS, few or many flowered, simple or (more rarely) branched, from one to two feet high. SEPALS and PETALS nearly equal, linear-lanceolate, extremely acuminate, an inch or more long, greenish-yellow richly blotched with brown. LIP shorter than the sepals heart-shaped, with a very acuminate slightly recurved apex, white with dark brown spots and a purplish 2-lobed callus at the base. COLUMN pubescent, club-shaped, almost wingless.

Though scarcely to be classed among the more attractive species, O. cordatum is occasionally seen at our Shows with branching scapes 2 feet high and flowers much more richly coloured than those in the Plate. It is found both in Mexico and Guatemala (whence plants were sent to me by my lamented friend Skinner), but always at high elevations.

It flowers in the early summer without any special treatment, except that it is perhaps more impatient of water than some of its congeners.
