The branching stem grows erect when new and then the branches droop to the ground with age, forming a bushy clump or mat. Each leaf is made up of three fleshy oval leaflets. Flowers appear in dense racemes on older stems and solitary in leaf axils on new stems. Each flower has generally four hairy green sepals and four yellow petals grouped together on one side of the involucre. The whiskery yellow stamens protrude up to 1. 5 centimeters from the flower.

Cneoridium is a monotypic genus in the Rutaceae (citrus family) which contains the single species Cneoridium dumosum, known by the common name Bushrue. This is an aromatic is shrub native to the coastal bluffs of southern California and Baja California. This highly-branched shrub may exceed a meter in height and sprawl about as wide. Its twigs are covered in small linear green leaves and flowers in clusters of one to three. Each flower is just over a centimeter wide with four or five rounded white petals and eight yellow-anthered white stamens.

Each berry contains one or two spherical seeds. May cause dermatitis in some people so use with caution. In the summer, the leaves of the plant turn an attractive golden color.

This is a tough and easy to grow plant. Amazingly drought tolerant but still tolerates occasional summer water better than most plants. It prefers full sun, and tolerates a wide variety of soil types. In the summer, its leaves turn an attractive golden color, and will green back up after the rainy season begins.

Coleogyne is a monotypic genus in the rose family containing the single species Coleogyne ramosissima, which is known by the common name blackbrush. This thorny, aromatic shrub is native to the deserts of the southwestern United States. It is a thickly branched thicket which may spread across the ground in clumps or grow erect to approach two meters in height. It is drought-deciduous, such that its branches are covered in clumps of fuzzy thick leaves until the hottest, driest parts of the desert year when it drops some of its foliage and becomes dormant for the season. This plant forms vast monotypic stands across the desert floor and on scrubby slopes. Flowering is triggered by a heavy spring rain in this desert-adapted species. The leathery flowers grow at the ends of small stems. They are encased in thick, fuzzy sepals which are yellow inside and reddish or orange on the outer surface. There are no petals, but the sepals remain after the flower opens, surrounding the patch of whiskery stamens and the central pistil. The fruit is an achene a few millimeters long. The plant reproduces from seed, but very rarely. The seeds do not disperse well and seedlings do not survive in large numbers. A narrow range of temperature and moisture is required for the reproduction of this species, so it is sporadic, but the plants are hardy and long-lived.
