[edit] Description
Grows to a total length 770 mm, tail length 170 mm.[5]
Dorsal scales in 21 (rarely 23) longitudinal rows at midbody; 9-11 upper labials, first upper labials separated from nasals by a distinct suture; a single supraocular; above green, below pale green to whitish, the two separated by a bright bicolored orange or brown (below) and white (above) (males) or white (females) ventrolateral stripe, which occupies the whole of the outermost scale row and a portion of the second row; ventrals 155-169; subcaudals 52-76, in males the base of the tail enlarged to the level of subcaudals 20-25; hemipenes long and slender, smooth, without spines.[5]
This species is most often confused with T. stejnegeri (q.v.), the two have quite distinct hemipenes, which does not make identification of individuals in the field or in the laboratory any easier without recourse to (a) male individuals and (b) an examination of the hemipenes. However, the two species are not known to have overlapping distributions, at least based on available materials. Also, closely allied to T. popeorum is T. yunnanensis (q.v.); ordinarily, the two are more easily be told apart by the number of midbody scale rows, 21 in T. popeorum, 19 in T. yunnanensis.[5]
[edit] Geographic range
Northern India, Burma, Thailand, West Malaysia and Vietnam. In Indonesia, it occurs on the islands of Sumatra, Mentawai Islands (Siberut, Sipora, North Pagai) and Borneo. The type locality, designated by lectotype, is listed as "Khasi Hills, Assam" (India).[1]
Gumprecht et al. (2004) consider records for Bangladesh, Cambodia and Vietnam to be highly questionable, as they are likely based on misidentifications involving other species of Trimeresurus.[3]

[edit] Taxonomy
There are differences in opinion as to the correct spelling of the specific epithet. The following is from David & Vogel (1996):[6]
This species was named in honour to Clifford H. Pope and Sarah H. Pope. The original spelling of the specific epithet, popeiorum, was corrected into popeorum by Smith (1943:518) on the basis that it was indeed a clerical error. Unfortunately, according to the Art. 32 (c, ii) of the Code (ICZN, 1985), such a change does not fall into the category of a “correction of an incorrect original spelling." According to the Art. 33 (d), the use of a termination -orum in a subsequent spelling of a species-group name that is a genitive based upon a personal name in which the correct original spelling terminates with -iorum, is an incorrect subsequent spelling, even if the change is deliberate. The original spelling, popeiorum, must therefore be conserved.
