Description
Adults may attain a total length of , which includes a prehensile tail  long.

Dorsally, T. puniceus is gray, brown, or red, with dark blotches or crossbars, which may merge to form an undulating stripe.  On each side of the head, behind the eye, is a light streak. Ventrally, it is powdered with dark brown, and usually has lateral series of yellowish spots. › The body length of the Trimeresurus puniceus depends on the gender. The male adult body ranges from 60-70cm and the adult female body 100-130cm in length. 

Scalation includes 21-23 rows of dorsal scales at midbody, 158-173 ventral scales, 41-56 subcaudal scales, and 10-13 supralabial scales. The dorsal scales are weekly keeled, and the anal plate is entire.

Venom
T. puniceus can be found on Java and southern Sumatra. Envenomation is still a relatively major issue in certain parts of the world. One major area affected by envenomation is Asia.  Through the study of the venom excreted by T. puniceus, we can potentially observe and find the effects of the venom based on the concentration and amount received. Research has shown that the higher the concentration of the venom, the greater the effect on the red blood cells. This change is referred to as morphology.

Common names
Flat-nosed pitviper, flat-nosed pit viper, ashy pit viper.

Two more common names, Wirot's pit viper and Siamese palm viper, which were applied to T. wiroti, are now part of the synonymy of T. puniceus.''
