Standard Cyclopedia of Horticulture

Phaius (Greek, dark; referring to the color of the flowers). Often spelled Phajus. Orchidaceae. Very large orchids with ample foliage and all clustered stems terminating in racemes of showy flowers. Sepals and petals similar, spreading or half-spreading; labellum large, with the lateral lobes inclosing the column, usually gibbous or spurred behind; column slender; pollinia 8. Distinguished from Calanthe by the free labellum; from Thunia by the leafless bracted scape which does not terminate the leafy axis.—About 20 species, natives of Trop. Asia, Afr., Austral., China, Japan, and the South Sea Isls.

The genus Phaius includes both epiphytic and terrestrial representatives. The noteworthy epiphytic types are native of Madagascar, including P. tuberculosus, P. simulans, and P. Humblotii. However they are not frequently represented in orchid collections. They enjoy a warm moist atmosphere as for vanda. The potting medium should include chopped peat and moss in equal proportion. When potting, small rafts with the potting medium packed around or sections of fern stems, the latter being preferable, should be placed in the center of the pot or basket. The terrestrial species, especially P. grandifolius, are well known, being one of the first orchids put under cultivation. It dates as far back as 1778, when it was imported from China. Various species are native to low-lying swampy places of tropical Asia and Australia, and have also become naturalized in the West Indies. They are of easy culture and will grow in an ordinary warmhouse associated with palms. They delight in moisture throughout the year, in a growing medium of sandy fibrous sod-soil, with plenty of organic fertilizer in a dried state mixed with the soil and also in liquid form when in full growth. The main factor to bear in mind is perfect drainage. Plants are increased readily by the division of the dormant pseudobulbs. Upward of thirty garden hybrids are under cultivation at the present time, including some interesting bigeneric forms. CH

P. amboinensis, Blume. Fig. white, with some veining on the lip. Malaya.—P. Ashworthianus, Sander. A garden hybrid (P. Mannii X P. maculatus). fls-. large sepals and petals clear old gold; labellum large, of the same color, with many radiating chocolate lines, outer surface clear yellow.—P. callosus, Lindl. (Geodorum plicatum. Voigt). Resembling P. grandifolius in habit: sepals and petals dull reddish brown; lip white with tinge of pink, dark purple spot beneath, with yellow on the 2-lobed spur. Malaya.—P. CMpmonmi (syn. P. Humblotii X P. Phoebe).—P. Cooksonae (P. grandifolius X P. Humblotii). Sepals and petals nankeen-groen, the broad frilled tip yellow at the base with purple-brown markings, the front lobe rose.—P. Cailcmaii—P. simularis X P. Wallichii.—P. Cooperi, Rolfe. Sepals and petals bright red-brown in front, pale yellow behind, about 2 in. long: lip funnel-shaped, white at first, soon changing to yellow.—P.fragrans, Hort. Belonging to same group as P. tuberculosus, but fls. smaller and more numerous, in color resembling P. Humblotii.—P. Marthae (P. Blumei X P. simulans). Fls. nankeen-yellow, the base of the lip with rose markings and veined light yellow, the front lobe tinged pink.—Norman (P. Sanderianus X P. tuberculosus). Sepals and petals cream to pink, lined, the lip with a reddish purple base, veined yellow ana with 3 yellow keels, the midlobe rose, blotched purple and tipped white.—P. oakwoodiensis (syn. P. Cooksonii X P. Humblotii).—P. Opoixi (P. Wallichii x P. Humblotii.).—P. Sanderianus, Hort. Fls. 6 in. wide or more, the sepals and petals copper-red, the lip with a yellow base, crimson center, and white midlobe.—P. schnoebrunnensis (syn. P. grandifolius X P. assamicus).—P. simulans, Rolfe. "The epiphytal species known in gardens under the name of P. tuberculosus is not the original plant, and has been renamed P. simulans in allusion to the remarkable resemblance which its fls. bear to those of the original species.
