Base Species or Cultivar:
The cultivar came from a variegated sport of an Alocasia cuprea from a batch of regular cupreas acquired in a garden. Asexual propagation was succesfully done using its corm and has shown that the unique feature is stable and reproduced true to form in the next generations.
A reference to the color of the variegation similar to the Gangsa — a copper - brass percussion intrument from the Cordillera. Coincidentally, the namer also acquired the Plant in a garden tucked in the mountains of Benguet, a province of Cordillera Region, the Philippines.
Plant type — Tropical perennial herb.
Plant habit — Upright
Height and spread — 12 -18 inches tall, 20 inches in spread
Roots — Fleshy.
Propagation type — corms, offsets
Corm — Circular in shape, surface texture is slightly glossy at apex and bark-like and nubby at base
Growth rate — Moderately vigorous.
Leaf shape — Ovate-Cordate
Leaf division — Single
Leaf base — cordate
Leaf apex — Cuspidate and with tip downward.
Leaf venation — Pinnate,
Leaf margins — Entire
Leaf attachment — Petiolate
Leaf arrangement — Alternate
Leaf surface and color — Juvenile leaves: Both abaxial and adaxial surfaces exhibit reddish coloration (deeper on abaxial). Olive green - brass variegation is observed more prominently at the adaxial surface.
Adult leaves are large, ribbed, and glossy, resembling copper-tinted grey breastplates. The reddish coloration is maintained only on the abaxial sides. Olive green - brass variegation is observed more priminently at the adaxial surface.
Leaf orientation — vertically
Leaf size — Up to 18 inches in length and about 10 inches in width
Petioles — Held erect to semi-erect, 12 inches in length, 6mm in diameter.
Bloom and Fruit:
Inflorescence paired. Spadix surrounded by a spathe, male portion held above female portion. Female zone cylindric, ca. 2 cm long x 8 mm wide; ovaries subglobose, longitudinally 3-4-ribbed; stigma raised on a very short slender style, conspicuously 2-4-lobed; sterile interstice not attenuate, isodiametric with male and female zones, ca. 2 whorls of rhomboid synandrodia; male zone cylindric, 2/3rds or all within the lower spathe, 2 cm long; synandria rhomboid, 4-6-merous, with the synconnective raised above but not overcapping the thecae; thecae opening by apical pores; appendix white, spindle-shaped, blunt, faintly irregularly channelled, ca. 2 cm long, constricted at union with male zone
This cultivar is distinguished by the subtle variegation ranging from brass color to olive green. The petioles also display the same variegation. These following traits have been repeatedly observed and represent the characteristics of the new cultivar ‘Gangsa’
