77B9CB2B847B5F4FB42BC8E18EA42DF7.taxon	diagnosis	Diagnosis. Similar to Hoya edeni King & Hook. f. in its shrubby habit and caudate and curved inner corona lobe processes, distinct by the corona processes (wavy to serpentine in H. medusa versus linear and curved at the tip in H. edeni), corolla shape (urceolate in H. medusa versus rotate with reflexed lobes in H. edeni) and size (8.5 - 10 mm in H. medusa versus c. 20 mm in H. edeni).	en	De Leon, Miguel David, Cabactulan, Derek, Cuerdo, Ryu D., Rodda, Michele (2023): A new species of Hoya R.

Stems slender, terete, 1.5 - 7 mm in diam., green, sparsely puberulent when immature, turning lignified, brown and glabrescent when mature, internodes 2.8 - 6 cm long. Leaves: petiole stout, usually curved, canaliculate above, flattened towards lamina base, 3 - 7 mm long, 1.5 - 2.0 mm in diameter, dark green, sparsely pubescent turning glabrescent when old; blades coriaceous, stiff, flat to slightly curved, variable in shape, oblong, ovate, to elliptic-ovate, 55 - 90 mm long x 20 - 34 mm wide; base acute to obtuse, apex acute to acuminate, with a caudate tip, adaxially mid-green, abaxially light green; margins entire, occasionally slightly undulate; adaxially and abaxially sparsely pubescent to glabrescent in older leaves; venation pinnate-brochidodromous, with 4 - 8 lateral veins on each sides of mid vein, prominent (very pale green) on younger leaves and obscure on older leaves yet clearly visible on dried specimens; colleters one at each lamina base, conical, c. 0.20 mm long, grayish brown. Inflorescence extra-axillary, umbelliform, convex, with up to 11 flowers (occasionally up to 16 flowers in particularly strong cultivated specimens). Peduncle short stout or sometimes sessile, cylindrical, 1.0 - 3.0 mm long and 1.0 - 2.0 mm in diam., perennial, sparsely pubescent. Pedicels terete, outer pedicels slightly curved, otherwise straight, 8 - 10 mm long and 0.5 - 0.8 mm in diam., light green, lenticellate except the base of the calyx which is pubescent. Calyx lobes oblong, 1.8 - 2 mm long, c. 0.50 mm wide, reddish, abaxially strigose, adaxially glabrous, basal colleters 1 between each calyx lobes, oblong, c. 0.02 mm long x c. 0.02 mm wide. Corolla basally urceolate, with flat spreading lobes, white, corolla lobes spreading, 8.5 to 10 mm in diam. across the corolla lobes, corolla tube 2.0 - 3.0 mm long, 4 - 5 mm in diameter, lobes triangular ovate, 2.5 - 3.0 mm long, 2.5 - 3.5 mm wide, apex acute, slightly revolute, margins revolute, corolla lobes adaxially densely strigose, densely hirsute towards the rim and interior of the tube and the column, abaxially glabrous; gynostegium stipitate; column cylindrical, 0.50 - 0.70 mm high x c. 0.50 mm in diam.; corona staminal 4 - 5 mm high, c. 3 mm in diam.; corona lobe bulbous-obpyriform, c. 3.5 mm long x 0.5 - 0.7 mm wide, inner (apical) process caudate, upright, curved, wavy to serpentine, meeting at the center and overlapping, erect above the gynostegium, outer (basal) process obovate, with basal revolute margins, guide rail raised, laterally compressed, prominent at the base of the corona lobes c. 0.80 mm long and extending c. 0.20 mm laterally. Pollinia erect, elliptic-oblong, c. 0.50 mm long, c. 0.22 mm wide; caudicle obovoid, c. 0.10 mm diam; corpusculum oblong, c. 3.0 mm long by c. 1.0 mm wide; ovary ovoid, c. 1.5 mm long, each carpel c. 0.9 mm wise at the base, glabrous. Fruit and seed not seen. Flowers vespertine lasting up to 15 days in cultivation, drying of the inner corona processes begins on the second day causing brown to black discoloration, flowers slightly fragrant, fragrance floral, powdery scent or mild jasmine persistent throughout the day and night.	en	De Leon, Miguel David, Cabactulan, Derek, Cuerdo, Ryu D., Rodda, Michele (2023): A new species of Hoya R.

77B9CB2B847B5F4FB42BC8E18EA42DF7.taxon	etymology	Etymology. The specific epithet refers to the serpentine processes of the inner corona reminiscent of the snake headdress of Medusa in Greek mythology.	en	De Leon, Miguel David, Cabactulan, Derek, Cuerdo, Ryu D., Rodda, Michele (2023): A new species of Hoya R.

77B9CB2B847B5F4FB42BC8E18EA42DF7.taxon	distribution	Distribution and ecology. Hoya medusa was collected by local collectors in Luzon Island, Mt. Cetaceo and has been in cultivation, circulated by local plant nurseries and plant hobbyists. It was first collected in low montane forest at 500 to 1,000 m where it was growing as an epiphyte in disturbed primary broadly leaf and mossy forest in full sun to part shade.	en	De Leon, Miguel David, Cabactulan, Derek, Cuerdo, Ryu D., Rodda, Michele (2023): A new species of Hoya R.
