Flora of North America species comparison

erect to spreading or recurved, green when young, soon becoming tan to brown, then nearly black when older, highly branched, twigs glabrous, glandular, usually resinous.

decumbent to ascending, green when young, often reddish tinged, soon reddish brown to brown, branched, twigs long-stipitate-glandular (sometimes with crinkly hairs interspersed).

ascending to spreading;

blades usually elliptic to oblanceolate, occasionally spatulate, 10–15 × 0.5–1.5 mm, mostly adaxially sulcate, margins entire, midnerves usually obscure to weakly evident, apices acute, apiculate, faces glandular, sometimes irregularly gland-dotted (in shallow pits), resinous;

axillary fascicles present, persistent.

mostly erect or ascending;

blades spatulate (flat), 25–40 × 2.5–7 mm, midnerves (plus 2 smaller, collateral nerves) evident, apices acuminate, faces long-stipitate-glandular;
