Which juniper species in New Mexico produces seed cones with a reddish-brown, fibrous, and dry (not fleshy) exterior compared to other junipers?
Answer: One-seed juniper
One-seed juniper (Juniperus monosperma) cones typically contain a single seed and have a thin, dry, bluish-waxy coating rather than the thick fleshy cones of Utah juniper.
Alligator juniper gets its name from its bark. What pattern does this bark display?
Answer: Checkered squares resembling alligator hide
Alligator juniper (Juniperus deppeana) has thick, checkered bark broken into square or rectangular plates that closely resemble alligator skin.
A New Mexico tree with smooth, chalky white bark on upper branches and dark furrowed lower trunk is most likely:
Answer: Arizona sycamore
Arizona sycamore (Platanus wrightii) has a two-toned trunk — patchy white and cream upper bark exfoliating to reveal lighter layers, contrasting with darker lower trunk.
Which tree's foliage turns golden yellow in fall, is dioecious, and produces catkin-like flowers in riparian zones of northern New Mexico?
Answer: Fremont cottonwood
Fremont cottonwood (Populus fremontii) is dioecious, produces catkins before leaves emerge, and provides brilliant yellow fall color along New Mexico's Rio Grande corridor.
An arborist in the Jemez Mountains notices a tree with 5-needled bundles, white-striped needle undersides, and cones 5–10 inches long. This is most likely:
Answer: Southwestern white pine
Southwestern white pine (Pinus strobiformis) has 5-needle bundles, long cylindrical cones, and is the primary 5-needle pine of New Mexico's southern Rocky Mountains.
The velvet mesquite and honey mesquite both occur in southern New Mexico. The key visual difference is:
Answer: Leaflet surface texture — velvet mesquite has densely hairy leaflets
Velvet mesquite (Prosopis velutina) has densely pubescent (velvety) leaflets, while honey mesquite (Prosopis glandulosa) leaflets are glabrous or only slightly hairy.
Which New Mexico tree produces clusters of bright red or orange berries in autumn and has pinnately compound leaves with 11–17 leaflets?
Answer: Smooth sumac
Smooth sumac (Rhus glabra) produces upright clusters of red drupes and pinnately compound leaves that turn scarlet in fall, making it one of the most colorful native shrub-trees in New Mexico.
