|Growth habit||Stems are initially upright, but soon begin to sprawl and trail as they get longer.|
|Foliage||Stems are 2-4mm wide, with internodes 1-5cm long, smooth and hairless. The colour ranges from strong yellow green (144B) to moderate reddish brown (177A), with lighter green freckles.|
Leaves are asymmetrical pointed ovals, 4-7cm long and 2-4cm wide. The upper surface is smooth, sometimes with scattered hairs near the edges. Each half of the leaf has a bold silver stripe running its length, taking up 50-70% of its total width. The leaves are also overlaid with random pale sectors, which can cover anything from 0-100% of the leaf surface.
The base colour of the upper leaf surfaces is moderate yellowish green (138A), and the silver bands are greyish yellow green (191A) with a glittery metallic appearance. The pale sectors can range from pale greenish yellow (13D) to very pale purple (75D). In intense light, the leaves become speckled with dark purple (79A) or dark purplish red (N79A), and the leaf margins are strong purplish red (72A).
The leaf undersides are shimmery and moderate yellow green (138A) in moderate light, becoming dark purplish red (N79A) in intense light. Where there are pale sectors, these show through as strong purplish red (72A) on the underside. Sheaths are light yellow green (145C), striped with darker veins in intense light.
|Flowers||10-15mm across. Petals are strong purplish red (72B) to deep reddish purple (77A). Stamen filaments are purple, anthers and pistil are white.|
