Distribution

Macropodanthus includes eight species collectively distributed from the Andaman Islands, Thailand, and Peninsular Malaysia, east to Indonesia and the Philippines.

Ecology

Macropodanthus philippinensis L.O.Williams occurs in hill forests at an elevation of 500 m in the Philippines. In Borneo, M. rimauensis J.J.Wood is reported from lower montane forests at elevations of 1500–1600 m, and M. sabahensis J.J.Wood & A.L.Lamb is recorded from mixed lower montane forests on sandstone ridges. Macropodanthus teysmannii (Miq.) H.A.Pedersen occurs at elevations of 1200–1900 m in Sumatra.

General Description

Usually pendent, epiphytic herbs. Stem to about 10 cm long, obscured by leaf-sheaths, leafy. Leaves narrow, strap-shaped, apex unequally bilobed, coriaceous. Inflorescences often clustered, racemose, as long as the leaves, c. 7–25-flowered; rachis terete or laterally compressed, sometimes slightly keeled or winged, the keels or wings tapering upward and mutually continuous at their base, leaving a concavity where the flower has fallen; floral bracts scale-like, obtuse or acute. Flowers showy, long-lasting, opening simultaneously, sometimes sweetly scented, white or yellow, marked with red, lilac-pink or orange-brown. Dorsal sepal free. Lateral sepals and petals adnate to column foot. Labellum articulate to column foot and bent upward at an angle, motile, distinctly clawed, trilobed, carinate, side lobes linear or tooth-like, midlobe triangular, acute, sometimes reduced to a low fleshy keel, sometimes with a pair of raised linear appendages in front of side lobes; spur distinct, about 1 cm long, saccate, ecallose. Column slightly broadened at truncate apex, with small apical stelidia, column foot long; rostellar projection terminal, about as long as the column, filiform, closely appressed to inner surface of column; anther cap ovate, cucullate, apex often triangular, acute, pollinia two, globose, sulcate, stipe to 5 mm long, viscidium obovate or oblong.

Distribution

The only known species, Cryptopylos clausus, has been recorded from Thailand, Laos, Cambodia, Vietnam, and Indonesia.

Ecology

Cryptopylos clausus is epiphytic in evergreen forests from 300 to 1500 m.

General Description

Epiphytic herbs. Roots terete, not branching, glabrous, smooth. Stem patent, rooting at the base. Leaves conduplicate, articulate, distichous, oblong to linear, subfalcate, twisted at the base so as to lie in one plane with the stem, margins entire, apex unequally bilobed. Inflorescence lateral below the lowest leaf, pendent, racemose, many-flowered; peduncle elongate, rachis continuing the line of the peduncle, flexuose, only slightly thicker than the peduncle. Flowers non-resupinate, about 2 cm wide, probably short-lived, opening in succession a few at a time, quaquaversal, glabrous, ochre-yellow, suffused or spotted with brown, labellum white marked with violet. Sepals and petals entire, free, obtuse. Labellum articulated with the apex of the column foot, spurred, trilobed; spur with a narrow opening, cylindrical, curved, continuing the line of the column foot. Column long and slender, column foot shorter than column; anther cucullate, pollinia two, porate, stipe longer than the pollinia, linear-subspatulate, viscidium small. Ovary and pedicel curved.
