Philodrayas baroni can reach a total length of 59 – 71 inches. The males are smaller than the females. The length of the tail is about 30% of the total body length. The head is small and elongated, with an extension of the rostral scale, forming a small flexible nasal protuberance more developed in males. The coloration of the body is rather variable. Usually it is green, but there are found specimens tending to blue or brown. The pattern can be uniform or with black longitudinal stripes on the back and on the sides, on the anterior third of the body. The ventral area under the black lateral lines can be white or yellowish-white, sometimes with shades of green or blue. Threats include habitat loss due to deforestation for agricultural development. It is also collected for the pet trade.
