Claoxylon australe: Claoxylon australe, known as the Brittlewood is a common rainforest shrub or understorey tree.  The habitat is all types of eastern Australian rainforests.  The natural range of distribution is from Eden (37° S) in south eastern New South Wales to Bowen (20° S) in tropical Queensland.

Ceanothus velutinus: Ceanothus velutinus, with the common names snowbrush ceanothus, red root, and tobacco brush, is a species of shrub in the family Rhamnaceae.  It is native to western North America from British Columbia to California to Colorado, where it grows in several habitat types including coniferous forest, chaparral, and various types of woodland.

Mark's and Jack's Island Natural Area Preserve: Mark's and Jack's Island Natural Area Preserve is a 2000 acre Natural Area Preserve located in Accomack County, Virginia.  The preserve supports Chesapeake Bay beach habitat, as well as various types of marsh, shrub, and forest vegetation.  Many species of birds can be found in the preserve's wetlands, and numerous plant species live in the marsh, including marsh-elder.  Loblolly pine and black cherry may be seen along the tops of some old dunes.  The beaches provide a home for the northeastern beach tiger beetle.

Ceanothus sanguineus: Ceanothus sanguineus is a species of shrub in the buckthorn family Rhamnaceae known by the common name redstem ceanothus.  It is native to western North America from British Columbia to Montana to far northern California; it is also known from Michigan.  It grows in temperate coniferous forest habitat in forest openings amidst the conifers.  This is an erect shrub approaching 3 meters in maximum height.  Its stem is red to purple in color, its woody parts green and hairless when new.  The deciduous leaves are alternately arranged and up to about 10 centimeters long.  They are thin, light green, oval, and generally edged with glandular teeth.  The undersides are sometimes hairy.  The inflorescence is a cluster of white flowers up to about 12 centimeters long.  The fruit is a three-lobed smooth capsule about 4 millimeters long.  This shrub is an important food plant for wild ungulates such as the Rocky Mountain Elk, it is browsed eagerly by many types of livestock, and the seed is consumed by many types of animals.

Mucuna bracteata: Mucuna bracteata is a leguminous plant.  It is a nitrogen-regulating plant that is used in agroecosystems operating around certain types of agricultural plant systems including: rubber trees, oil palm, citrus and coconut.  "M. bracteate" is a cover crop which helps to cover and shield the soil from weeds or plants, as well as providing rapid growth for existing agricultural crops, preventing soil erosion, and providing nitrogen fixation.  The "Mucuna bracteata" crop grows about 10–15 cm/day in conditions similar to those that rubber and palm oil plants thrive in.

Lycium cooperi: Lycium cooperi is a species of flowering plant in the nightshade family known by the common name peach thorn.  It is native to the southwestern United States, where it grows in a variety of desert and mountain habitat types.  This is a bushy, erect shrub approaching a maximum height of 4 m with many rigid, thorny branches.  The branches are lined thickly with fleshy oval or widely lance-shaped leaves each 1 - long and coated with glandular hairs.  The inflorescence is a small cluster of tubular flowers roughly 1 - long including the calyx of fleshy sepals at the base.  The flower is white or greenish with lavender or green veining.  The corolla is a tube opening into a face with four or five lobes.  The fruit is a yellow or orange berry under a centimeter wide containing many seeds.

Alyxia oliviformis: Alyxia oliviformis, known as Maile (pronounced "MY-lĕ") in Hawaiian, is a species of flowering plant in the dogbane family, "Apocynaceae", that is native to Hawaii.  It grows as either a twining liana, scandent shrub, or small erect shrub, and is one of the few vines that are endemic to the islands.  The binomial nomenclature means "chain resembling olive" in Latin.  The leaves are usually ternate, sometimes opposite, and can show both types on the same stem.  Flowers are quite inconspicuous and have a sweet and light fragrance of honey.  The bark is most fragrant and exudes a slightly sticky, milky sap when punctured, characteristic of the "Apocynaceae" family.  The entire plant contains coumarin, a sweet-smelling compound that is also present in vanilla grass ("Anthoxanthum odoratum"), woodruff ("Galium odoratum") and mullein ("Verbascum" spp.) .  Fruit are oval and dark purple when ripe.  "Maile" is a morphologically variable plant and the Hawaiian names reflect this (see Ethnobotany section).

Zenobia (plant): Zenobia, called honeycup, is a North American genus of shrubs in the heath family.

Mucuna: Mucuna is a genus of around 100 accepted species of climbing lianas (vines) and shrubs of the family Fabaceae and typically found in tropical woodlands.

Olearia canescens: Olearia canescens is a shrub belonging to the family Asteraceae.  Commonly known as Grey Olearia, Grey Daisy Bush or New England Daisy Bush, the species is endemic to Eastern Australia, growing in monsoon forests and drier rainforest types from North Queensland to northern New South Wales.  "O. canescens " can grow as a woody shrub up to 6 metres in height, an unusual habit for a member of the daisy family.  However it more commonly exists as a low shrub of 2 – 4 metres with only a slightly woody form.
