Phyllorhynchus is a genus of snakes in the family Colubridae. The genus is endemic to the southwestern United States and adjacent northwestern Mexico[1]


The genus Phyllorhynchus contains two species which are recognized as being valid.[1]

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


The specific name, browni, is in honor of Herbert Brown (1848–1913),[2] who collected the holotype.[3]


Snakes of the genus Phyllorhynchus are heavy-bodied, but small, 6 to 20 in (15 to 51 cm) in total length, which includes a short tail. The snout is short and shovel-like. The rostral scale is enlarged and has free lateral edges.[4]
