Base Species or Cultivar:

Alocasia cuprea


Cultivar Origin:

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.

Name Origin:

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.

Growth Habit:

General Description

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 Blade:

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

Distinguishing Characteristics:

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’
