Juniperus deppeana var. gamboana
Cedro, cipres, cipres común, bac'il nuhkupat [Tzeltal, in Chiapas], K'uk'',ton, nukul pat [Tzotzil in Chiamas], gambo juniper (Zanoni and Adams 1979).
Syn.: Juniperus gamboana Martínez 1944. This was the accepted name until DNA sequencing (nrDNA and trnC-trnD) showed that gamboana trees fall within a clade that includes the other varieties of J. deppeana (Adams and Schwarzbach 2006).
Trees up to 12 m tall, the stem usually branching 1-2 m above base. Branches ascending to erect, crown rounded or broadly pyramidal. Bark dark ash-brown, about 5 mm thick, forming quadrangular plates. Terminal whip branches ascending to erect, with straight tips, bearing red-brown, scaly bark. Angle of branching of ultimate twigs 35-45°. Scale leaves yellow-green to green, mostly opposite, ovate to elliptic, 1.5-2 mm long with acute to obtuse, appressed tips; margin finely toothed (20X hand lens). Seed cones globose, red-brown with a light bloom, 5-8 mm diameter, pulp soft. Seeds brown, 1(-2) per cone, ovoid, 4-6 × 3-4 mm with several large grooves; hilum about two-thirds length of seed (Zanoni and Adams 1979).
Mexico: Chiapas; Guatemala: Huehuetenango; at 1670-2200 m elevation, on limestone soils in understory of Quercus-Pinus-Juniperus cloud forests or in open pine (Pinus oocarpa) forest (Zanoni and Adams 1979, Farjon 2005).
Zanoni and Adams (1979) report collection locations for many herbarium specimens; among the more specific are (1) Four miles N of Teopisca on Highway 190; (2) Sixteen km NW of Comitán near Lake Jusnajav; (3) Three miles SW of Pinola Las Rosas on road to Soyatitan, municipio Venustiano Carranzo. I believe these are all in Chiapas.
Farjon (2005) provides a detailed account, with illustrations.
