Taxonomic notes

Type locality in Chiapas, 12 km S of Comitan; hence the epithet (Zanoni and Adams 1979).

Description

Trees to 10 m tall, usually with a single trunk branching several meters above base. Crown rounded or broadly pyramidal. Bark light ash-brown, about 5 mm thick, exfoliating in long strips. Terminal branchlets ascending to erect, branch tips straight, red-brown with scaly bark. Angle of branching on ultimate twigs 35-45°. Scale leaves green, mostly opposite, ovate with appressed acuminate tips, 1.5-2 mm long, margin finely toothed (requires a 20X hand lens); very slender ultimate branchlets (less than 1 mm thick); very weak odor due to unusually low terpenoid content (Zanoni and Adams 1979).
