Flora of North America species comparison

erect to ascending, green when young, fastigiately branched, glabrous, gland-dotted, 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).

blades ascending, sometimes spreading when older, filiform to narrowly oblanceolate (adaxially sulcate to concave), 10–20 × 1–2 mm, midnerves not evident, apices acute, sometimes apiculate, faces glabrous, regularly gland-dotted (in circular, deep pits), resinous;

axillary leaf fascicles sometimes present, shorter than subtending leaves.

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;
