Rostral scale as deep as broad or broader than deep; upper head-scales small, smooth, imbricate; supraocular scale narrow, rarely broken up; internasals in contact or separated by one or two scales; 8 to 13 scales on a line between the supraoculars; usually one or two, rarely three, series of scales between the suboculars and the labials; 9 to 12 upper labials, second usually forming the anterior border of the loreal pit, third largest; temporal scales smooth.

Dorsal scales more or less distinctly keeled, in 21 (rarely 19 or 23) rows. Ventrals 145–175; anal scale entire; subcaudals in two rows 53–76.

Upper parts usually bright green, rarely yellowish, greyish, or purplish brown, with or without black, brown, or reddish spots; usually a light, white, yellow, or red streak along the outer row of scales; end of tail frequently yellow or red; lower parts green, yellow, or whitish.[6]

Grows to a total length of 3.25 feet (0.99 m); tail 5.5 inches (14 cm).[6]

Common names[edit]

Trimeresurus gramineus (satara, Maharashtra)

Bamboo pit viper,[7][8] Indian tree viper,[9] bamboo snake, Indian green tree viper, green tree viper,[10] bamboo viper,[11] bamboo pitviper,[12] boodro pam, grass-green snake,[13] green pit viper.[14]

Geographic range[edit]

The range of this species is restricted to Peninsular India and Central India. It is a hill-dwelling species found in parts of Eastern Ghats, Western Ghats, hill ranges in the Malwa plateau and Seoni district. It occurs in the states of Andhra Pradesh, Tamil Nadu, Telangana, parts of Kerala, Karnataka, Goa, Maharashtra, Odisha, Jharkhand, Madhya Pradesh and even in parts of West Bengal.

The type locality is "Vizagapatam, India", which is based on Russell (1796).[2]


It is found in hills of 300-1600 m asl elevation, frequenting bamboo groves and forests, often near streams.[14]

venom type[edit]

Predominantly Hemotoxin, but not that thoroughly documented.


T. gramineus is a slow-moving, arboreal and nocturnal snake. An ambush foraging snake, relying on its camouflage and sit-and-wait strategy for prey-capture. Becomes active during the monsoon season. When threatened, it gets defensive and lunges forward with open mouth. May strike repeatedly, often vibrating the tail-tip, when further provoked.[14]


It feeds on chiefly lizards, frogs, mice and small birds.[14]


T. gramineus is ovoviviparous. Adult females gives birth to 6 to 11 young ones, which measure up to 4.5inches in length.
