Abies

Trees evergreen, crown usually spirelike to conic, sometimes flat to round topped in age. Bark initially thin, smooth, bearing resin blisters, in age furrowed and/or flaking in plates. Branches whorled, irregular internodal branches occasionally produced by epicormic sprouting (growing from a dormant bud) ; short (spur) shoots absent; leaf scars prominent, ± circular to broadly elliptic, flush with twig surface, slightly depressed, or slightly raised evenly all around. Buds ovate or oblong, resinous or not, apex rounded or pointed. Leaves borne singly, persisting 5 or more years, spirally arranged but often proximally twisted so as to appear either 1-ranked (pointing up like toothbrush bristles) or 2-ranked, sessile, typically constricted and often twisted above the somewhat broadened base, sheath absent; leaves on vegetative branches flattened, frequently grooved adaxially, usually notched to rounded at apex; leaves on fertile branches sometimes appearing 4-sided, upright, sharp-pointed to rounded at apex; resin canals 2. Cones borne on year-old twigs. Pollen cones grouped, ovate or oblong-cylindric, leaving gall-like protuberances after falling, yellow to red, green, blue, or purple. Seed cones maturing in 1 season, erect, ovoid to oblong-cylindric or cylindric, not falling whole but scale by scale, cone axis persisting as an erect "spike" on branch; scales shed individually, fan-shaped, lacking apophysis and umbo; bracts included to exserted.

Callistemon

Bottlebrush (Callistemon) is a with 34 species of shrubs in the family Myrtaceae. The majority of Callistemon species are endemic to Australia; four species are also found in New Caledonia. They are commonly referred to as bottlebrushes because of their cylindrical, brush like flowers resembling a traditional bottle brush. They are found in the more temperate regions of Australia, mostly along the east coast and south-west, and typically favour moist conditions so when planted in gardens thrive on regular watering. However, at least some of the species are drought-resistant. [more]
