1. Leaves with orange resinous glands or gland-tipped hairs at least beneath, bruised plant strongly aromatic; without spine-like branches; flowers in small clusters.

2. Leaf blades ± copiously covered with short spreading gland-tipped hairs; stem with abundant stalked glands; flowers in branched axillary cymes.

D. botrys

2. Leaf blades with mostly sessile glands on the underside; stem glabrous or pubescent, but not or only sparsely glandular; flowers in axillary (and terminal in D. ambrosioides) spike-like inflorescences.

3. Perianth lacking glands; leaves with only sessile glands beneath (except sometimes some appressed hairs on the main veins).
