Podolepis gracilis (common name slender podolepis) is a slender, perennial herb native to Western Australia, belonging to the Asteraceae family. [4]
The species was first described in 1828 by Robert Graham based on plant material grown from seed said to have been collected in New South Wales and sent to England by Charles Fraser, the NSW colonial botanist. [1] [2]
Graham described the plant as follows:
Root descending, tapering, having short, lateral, branching fibres, annual. Stem erect, slender, very slightly compressed, smooth and shining, slightly flexuose, branched; branches suberect, resembling the stem. Leaves 3-nerved, central nerve keeled behind, glabrous, shining, somewhat succulent, quite entire, sessile and stem clasping, the lower (3½ inches long, ¾ of an inch broad) ovato-oblong, with a short central point, the upper ovato-acuminate, and gradually becoming smaller towards the flowers. Flowers radiate, terminal or axillary. Peduncles (3-4 inches) long, filiform, and resembling the branches, which, indeed, they should perhaps be considered, as they have distantly scattered along them abortive flower-buds, each covered with an inconspicuous leaf resembling a bractea. Anthodium ovate, imbricated, dry, membranous, shining, greenish, when withered pale brown; scales ovate, entire, having a distinct middle rib occasionally projecting at the apex in form of a little mucro, on rough footstalks, in the inner scales as long as themselves, but shorter in the outer, which are loose, and extended a little way on the peduncle. Receptacle naked, tubercled. Florets of the disk (nearly ¾ of an inch long) hermaphrodite, rose-coloured, especially at their apices, divaricated, and projecting outwards between the tubes of the ray, regular, 5-cleft, segments spreading. Anther-tube included, bursting at its apex, and discharging white pollen; filaments nearly as long as the anthers, inserted into the corolla above the middle of the tube. Ray at first rose coloured, but soon fading to white, spreading, (1¼ inch across,) corollulae ligulate; tube (⅜ths of an inch long) filiform; limb equal in length to the tube, linear-oblong, cordate at the apex, bi-nerved. Seeds small, leaden coloured, lanceolate-oblong, dotted, slightly tomentose, having at the base an umbilicus, which is circular, white, slightly excavated, with prominent edges; many abortive. Pappus simple, rough, nearly equal, half the length of the tube of the ray, two-thirds of that of the disk. [2]

It is a shrub that grows to 2–3 m in height, with leathery leaves that are suborbicular or ovate-elliptic to oblong-elliptic, 4–8.5 by 2.5–4 cm in size. Flowers are yellow.
Rhododendron thomsonii (半圆叶杜鹃) is a rhododendron species native to northern India, Bhutan, Nepal, Sikkim, and southern Xizang in China, where it grows at altitudes of 3,000–4,000 m (9,800–13,100 ft). It is a shrub that grows to 2–4 m in height, with leathery leaves that are oblong-elliptic to ovate or orbicular to obovate, 3–7 by 2–6 cm in size. Flowers are red.
Psychotria capensis, the bird-berry, is a southern African evergreen shrub or small tree. It belongs to a genus which is used medicinally in many regions, 'Psychotria' being from the Greek for 'rejuvenating', in reference to the healing properties of certain species. Kew lists some 2,000 species of Psychotria growing throughout the warmer regions of both hemispheres, but only two of them occur in southern Africa, namely P. capensis and P. zombamontana.
Clematis hedysarifolia is a liana, endemic to peninsular India, belonging to the buttercup family (Ranunculaceae). It was described by Augustin Pyramus de Candolle and published in Regni Vegetabilis Systema Naturale 1: 148, in 1817.
Passiflora bogotensis is a climbing plant native to Colombia, in the genus Passiflora. It can also be found in Venezuela.
Passiflora quetzal is a species of flowering plant native to Mexico and Guatemala described in 2004. It is named after the quetzal, which inhabits the area.
Lepanthes kokonuko is a species of orchid from southern Colombia. L. kokonuko can be easily recognized by its caespitose medium-sized plants, elliptical coriaceous leaves, long loosely, flexuous and distichous inflorescences; strongly revolute lateral sepals, transversely bilobed petals with the upper lobe lanceolate (hornlike), and a bilaminate lip with the blades ovoid–lanceolate with a bipartite appendix.
Hoffmannanthus is a monotypic genus of flowering plants in the Asteraceae. There is only one known species, Hoffmannanthus abbotianus(O.Hoffm.) H.Rob., S.C.Keeley & Skvarla Its native range is Uganda and southern Tropical Africa. It is found in the countries of Angola, Kenya, Tanzania, Uganda, Zambia and Zaïre.

Mertensia sibirica, commonly known as Japanese bluebells or Siberian bluebells, is a species of flowering plant belonging to the family Boraginaceae. Originally discovered by Carolus Linnaeus, who named it Pulmonaria sibirica, this plant is found, as its name implies, in Eastern Siberia and northern China. After review of the plant's morphology, its taxonomic position was changed to Mertensia sibirica by botanist and plant collector George Don, who put forth the notion of the change, which was eventually accepted, most likely due to the striking resemblance to the related species in the Americas like Mertensia virginica, or Virginia bluebells.
