Growth habit: upright, sympodial, epiphyte. Roots: short, appearing from each internode and the base of the pseudobulb. Rhizome: terete, 3 mm in diameter, covered with persistent sheaths; bearing the pseudobulbs at intervals between 7 to 12 cm. Pseudobulbs: cylindrical, slightly fl at- tened, from 3 to 5 cm long by 7 mm wide; new pseudobulbs are covered by a large papery sheath; unifoliate. Leaves: thinly-textured, broadly ovate, apex acute; new leaves are heavily veined with purple. Petiole channelled, from 1.5 to 2.5 cm long; leaf blade from 9 cm to 12 cm long by from 4 to 6 cm wide. Infl orescence: appearing from the base of the pseudobulb, to 2 cm long, bearing 1 or 2 large fl owers. Flower colour: on the dorsal sepal

Mindanao. It grows as an epiphyte, in mossy forest, in shady locations at el- evations of 1,200 metres. This species is a member of section Pahudia Schltr. Comparison: Bulbophyllum hampeliae is related to Bulbophyllum virescens J.J.Sm., but differs in the much shorter length of the infl orescence; the one or two-fl owered infl orescence; the smaller fl owers and the smaller plant; and the very differently coloured blooms. Etymology: It is our great pleasure to name this magnifi cent species for Mrs. Charisma Hampel, a most gracious hostess, whenever we visit their nurs- ery.

Bulbophyllum marknaivei Cootes, R. Boos, & M.D. De Leon sp. nov. TYPE: Cultivated, Philippines: Mind- anao, Misamis Oriental, Claveria, May 26th, 2016, GH 004/2016, ex collected Mindanao: Misamis Orien- tal, Georg Hampel s.n. (HOLOTYPE: CMU00010806)

Growth habit: upright, sympodial, epiphyte. Pseudobulbs: minute; clustered; surrounded by persistent hairs; unifoliate. Leaves: petiolate: petiole 5 mm long, channelled; leaf blade, oblanceolate, apex unequally bilobed, to 6 cm long by 2 cm wide. Infl orescence: upright; 8.5 cm long, appearing from the base of the pseudobulb; rachis nodding, 3 cm long bearing about 16 tiny fl owers. Flower colour: base colour is pink heavily marked with Dendrobium butchcamposii deep red; labellum is golden-brown.

Petals: Cootes, Boos & M.D. De Leon narrowly lanceolate, to 1.5 mm long by 0.5 mm wide; with a central stripe. Lat- eral sepals: triangular, to 2.8 mm long by 1.8 mm wide; outer surface covered with tiny papillae. Labellum: oblong, fl eshy, deeply furrowed on the basal half, 1.2 mm long by 0.8 mm; covered in minute papillae. Column hood: squarish, exceeding both sides of the anther cap; minute 0.6 mm long.
