Sophora tetraptera foliage Sophora tetraptera flowers, foliage and seed pods. Most species of kōwhai grow to around 8 m high and have fairly smooth bark with small leaves. S. microphylla has smaller leaves (0.5–0.7 cm long by 0.3–0.4 cm wide) and flowers (2.5–3.5 cm long) than S. tetraptera, which has leaves of 1–2 cm long and flowers that are 3–5 cm long.
These illustrations depicted a vast array of European and exotic plants, often accompanied by detailed annotations on plant anatomy, including flowers, leaves, seeds, and fruits at various stages of development. While a few drawings were done in black ink or pencil, most were finely enhanced with watercolor.
The trunk is usually twisted and low branched, with grey-black rough bark. [2] [4] The thick leathery green leaves have a gummy feel to them and are glutinous when young. [2] [4] The plant flowers during the dry season after the bush fires which facilitate leaf flushing that supports flowering. [2]
Rudbeckia hirta is an upright annual (sometimes biennial or perennial) growing 30–100 cm (12–39 in) tall by 30–45 cm (12–18 in) wide.It has alternate, mostly basal leaves 10–18 cm long, covered by coarse hair, with stout branching stems and daisy-like, composite flower heads appearing in late summer and early autumn.
Sambucus nigra is a species complex of flowering plants in the family Viburnaceae native to most of Europe. [1] Common names include elder, elderberry, black elder, European elder, European elderberry, and European black elderberry. [2] [3] It grows in a variety of conditions including both wet and dry fertile soils, primarily in sunny locations.
The slit between the leaves contains the meristem and produces flowers and new leaves. The leaves of Lithops are mostly buried below the surface of the soil , with a partially or completely translucent top surface known as a leaf window which allows light to enter the interior of the leaves for photosynthesis .
The bark is smooth and has a light grey color. Leaves are in whorls of three to four, simple, penni-veined, membranous, and glabrous above. Leaf-blades are 10 to 50 centimeters long, 5 to 15 cm wide, widest in or above the middle, and cuneate at the base. Flowers are about 7 mm in diameter, white, with narrow corolla tube, placed terminal on twigs.
Plants in the genus Eucalyptus have bark that is either smooth, fibrous, hard, or stringy and leaves that have oil glands. The sepals and petals are fused to form a "cap" or operculum over the stamens, hence the name from Greek eû ("well") and kaluptós ("covered"). [4] The fruit is a woody capsule commonly referred to as a "gumnut".
