Bulbophyllum pingtungense S.S.Ying & S.C.Chen in S.S.Ying, Col. Ill. Indig. Orch. Taiwan 1: 499 (1985).

This name is accepted.



AWARD 20123377, PRJC



Six flowers on two umbel-like inflorescences on a 9cm wide x 10 cm tall stoloniferous plant grown in a 10 cm octagonal plastic basket filled with sphagnum moss ; flowers chartreuse; dorsal sepal striped and spotted mahogany; lateral sepals striped and spotted dark rose, basally, lighter apically; petals hirsute apically, overlaid dark rose; lip overlaid dark burgundy, chartreuse apex; column overlaid dark rose; substance firm texture waxy.



Please note: The judges considered the possibility that this may be Bulbophyllum wightii. In Bill Thoms, in his Book on Bulbophyllum (page 2010) indicates that the Bulbophyllum pingtungense illustrated is wightii.

Cirrhopetalum Lindley, Gen. Sp. Orchid. Pl. 45, 58. 1830, nom. cons.

Rhizome creeping or straggling; roots sprouting mainly below pseudobulbs, spreading; new shoots arising from basal node of

pseudobulb. Pseudobulbs distinct, apex with 1 leaf. Leaves persistent, thick. Inflorescence solitary, arising near pseudobulbs, 1-

flowered or a ± subumbellate raceme. Pedicel with basal node ± coinciding with attachment of subtending bract. Sepals 3–5-veined;

dorsal sepal with margins ciliate, fimbriate, or with paleaceous appendages (with a single apical thread in Bulbophyllum amplifolium);

lateral sepals twisted inward near base, with upper margins approaching or meeting and connate, margins glabrous to ciliolate.

Petals: margins fimbriate or with paleaceous appendages, 1–3-veined; lip: margins with or without auricles above base, margins

usually ± glabrous, adaxially ± glabrous. Column: stigma not protruding at its base, foot distinct; anther: front margin projecting or

not, abaxially with or without a low, rounded crest; pollinia 4, inner ca. 1/2 as long as outer or longer, all without appendages.

Fifty-seven provisionally accepted species: India to W Pacific, also Africa and Madagascar; 17 species (ten endemic) in China.

1a. Dorsal sepal entire, with a terminal thread only.
