Females can attain total lengths of up to 1 metre (39+3⁄8 inches), but males are typically only around 75 cm (29+1⁄2 in).

Phases vary greatly from having a black or brown colouration as a base, with orange and yellow banding, to others having a light green as the base colour, with yellow or orange banding, and many variations therein.

[3] The average litter consists of between twelve and fifteen young, with the neonates measuring 12–15 cm (4+3⁄4-5+7⁄8 inches) in total length.

[1] Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Tropidolaemus.

Two species here were once classified as Trimeresurus, but were given their own genus due to distinct morphological characteristics.
