    [A-EM]
    Morphology

    Schill and Pfeiffer (1977) studied pollen tetrads of C. lunifera (Rchb.f.) J.J.Sm. and described them as convex with laevigate sculpturing and a rounded sexine.

    General Description

    Epiphytic or lithophytic, usually stemless and commonly leafless herbs (C. godefroyana (Rchb.f.) Schltr. may have persistent leaves clustered at stem apex at anthesis). Roots flattened, ribbon-like or subcylindric, scabrid, green, photosynthetic. Leaves (when present) oblong-elliptic to ligulate, obliquely subacute or unequally bilobed, sometimes slightly falcate, articulate. Inflorescence lateral, racemose, rarely paniculate (C. ramifera Seidenf. and C. trudelii Seidenf.), erect or pendent, many-flowered, pilose or glabrous; floral bracts ovate-lanceolate. Flowers resupinate, ephemeral, fragrant, white to yellow, with or without reddish or purple spots. Sepals and petals free, subequal, oblong-ovate or oblong-elliptic, lateral sepals and petals usually laterally adnate to column foot by a broad base. Labellum clawed, articulate to apex of column foot, motile, trilobed, basal portion concave or saccate, with an erect or ascending, entire or weakly bilobed, pilose callus on inner surface of posterior wall, side lobes erect, midlobe commonly abbreviated, transverse, entire or rarely bilobed, disc often pilose. Column semi-terete, foot perpendicular to column, broad, at least twice as long as column; clinandrium shallowly excavate, with a membranous posterior margin; anther cap provided on either side with a long-filiform, glandular-tipped appendage, or appendages reduced to a small tooth; pollinia four, waxy, stipe sublinear, viscidium small; stigma transverse, deeply set; rostellum deflexed, shortly bifid after removal of pollinarium.

    Distribution

    There are about 10 (possibly more) species of Chiloschista collectively distributed from China and the Indian subcontinentthrough Southeast Asia to Australia, the Palau Islands, and Fiji.

    Ecology

    Species are epiphytes from 0 to 2000 m. Kores (1991) recorded Chiloschista godefroyana as epiphytic on trees on limestone and in coastal areas in Fiji. Comber (1990) reported C. javanica Schltr. as epiphytic on tree trunks where the light level is high, e.g., on roadside trees, on poorly grown teak, etc. Chiloschista lunifera is epiphytic on trees in deciduous forests at 200 m and on trees overhanging streams at 600 m in Thailand. Pearce and Cribb (2002) recorded C. parishii as epiphytic on the branches of Panax pseudoginseng Wall. (Araliaceae) between 600 and 1800 m in Bhutan. Chiloschista phyllorhiza occurs epiphytically in mangrove and Melaleuca L. (Myrtaceae) swamps in Australia. Chiloschista segawae (Masam.) Masam. & Fukuy. is epiphytic on tree trunks in forests between 700 and 1000 m in Taiwan. Pearce and Cribb (2002) recorded C. usneoides as epiphytic on oaks and in evergreen forests between 700 and 1900 m in Bhutan; it also occurs as a lithophyte on rocks in oak forests at about 1700 m in Bhutan. Chiloschista yunnanensis Schltr. is epiphytic on tree trunks at forest margins and in open forests between 700 and 2000 m in China.
