In all three arrangements, section Prostratae is circumscribed with little to no differences, though its placement within the broader system differs. The placement of B. blechnifolia in George's 1999 arrangement may be summarised as follows: Developing buds Habit Stems with developing leaves :Banksia ::B. subg. Banksia :::B. sect. Banksia ::::B. ser.

The goldenrod gall fly (Eurosta solidaginis), also known as the goldenrod ball gallmaker, is a species of fly native to North America. The species is best known for the characteristic galls it forms on several species in the Solidago, or goldenrod, genus. The fly's eggs are inserted near the developing buds of the plant. After hatching, the larvae migrate to an area below the plant's developing buds, where they then induce the plant's tissues to form into the hardened, bulbous chamber referred to as a gall. E. solidaginis’s interactions with its host plant(s) and insect, as well as avian, predators have made it the centerpiece of much ecological and evolutionary biology research, and its tolerance of freezing temperatures has inspired studies into the anti-freeze properties of its biochemistry.

Aeschynanthus is a genus of about 150 species of evergreen subtropical and tropical plants in the family Gesneriaceae. They are usually trailing epiphytes with brightly colored flowers that are pollinated by sunbirds. The genus name comes from a contraction of aischuno (to be ashamed) and anthos (flower). The common name for some species is "lipstick plant", which comes from the appearance of the developing buds.

Adult Andricus kollari are dark brown, and about in length. It has alternating sexual and asexual generations, each often taking two years to complete. Like all gall wasps, it causes the formation of parasitic galls on trees in which it lays its larvae. In May or June, a sexual female lays her eggs in the developing buds of susceptible oak trees using her ovipositor.

Like the new leaves and stems, developing buds are covered in reddish hair. Globular in shape with longitudinal ribbing, they grow to a diameter of 0.9–1.3 cm (0.4–0.5 in). The flowers fall leaving the cup-shaped woody seed pods or fruit, which measure 1.5–2.6 cm (0.6–0.8 in) long and 1.3–2 cm (0.5–0.6 in) in diameter. These shed the mature seed in February and March.

Adult D. brevis overwinter hiding in cracks and crevices. In the spring, the adult female lays its eggs on suitable host trees near the developing buds while in the summer it inserts the eggs into plant tissues such as the midribs of leaves. The eggs hatch in two to three weeks and then pass through five nymphal instars. At , nymphal development takes about 25 days in the laboratory, and during this period, up to 400 eggs and nymphs of the pear psyllid (Psylla pyri) are consumed.

The end of a gall where infection was complete: The tissue has since become necrotic on this hardened remnant. In the fall, the immature female adelgid, small, globular, and wingless (1.2-1.7 mm), finds a spruce on which to overwinter. In the spring when the winter thaw occurs, the female matures and lays some eggs in what resembles sacks (totalling several hundred eggs) on the branches near the developing buds. These, in fact, are not sacks, but individual tufts of white waxy threads that protect the eggs.

Flower close-up Native to Central America and Mexico, the plant is a climber with twining stems up to 5 m long and is densely to scattered with long hairy trichomes. The finely hairy, emerald green leaves are ovate to almost circular, 5 to 14 cm long. The base is heart- shaped, the edge is entire or lobed three to five times, the leaf lobes are pointed or tapering. The funnel-shaped, colorful flowers (blue to reddish purple, with whitish tube) are quite showy and are individually up to five in often dense cymose groups, in which fully developed flowers and developing buds stand together.

Plant with developing buds and a previous year's old seed pod While exploring Van Diemen's Land (Tasmania) in 1792–3, French botanist Jacques Labillardière collected specimens of what he later formally described as Embothrium truncatum in his 1805 work Novae Hollandiae Plantarum Specimen. The specific epithet is the Latin adjective truncatus, meaning "truncated" or "ending abruptly", referring to the end of the seed wing. This characteristic is not specific to the Tasmanian waratah; all members of the subtribe Embothriinae have truncate seed wings. Embothrium was a wastebasket taxon at the time, and Robert Brown proposed placing the species in a new genus, Telopea, in a talk he gave in 1809, publishing the new name Telopea truncata in 1810.
