Morphologically it looks close to Bronze-headed Vine Snake (A. perroteti) but can be differentiated from later by checking usually 2 (or 1) loreal scales which are absent in other Vine Snakes. Also it grows much larger than A. perroteti.
Maximum length- 78.8cm.
Body long and slender. Scales smooth, long and obliquely arranged. Dorsal color bright green or brownish-green with black and white interscale color.
Belly yellowish or greenish-brown with a white line running along the edge of ventral scales. Subcaudal scales paired in zigzag manner.
Head elongated, broader than neck; snout pointed but shorter than most of Vine Snakes; rostral appendages absent. Upper lip color (of supralabials) depends on dorsal and ventral color and always lighter. Oval shape eyes have horizontal pupils.
Long and slender tail ends with a pointed tip.
