Young plants, often several metres tall, and coppice regrowth have stems that are more or less square in cross-section with a prominent wing on each corner. Juvenile leaves are mostly arranged in opposite pairs, sessile , glaucous elliptic to egg-shaped, up to 150 mm (5.9 in) long and 105 mm (4.1 in) wide.
Jojoba is a dioecious plant, which brings one of its main challenges. Only the female bushes bear seeds that can be used for jojoba oil production. The sex of the plant is only visible to the eye after flowering (3-4 years after planting). [28] A proportion of 10% male plants is required in a field for efficient production.
Young plants and coppice regrowth have leaves that are linear to lance-shaped or curved, 40–100 mm (1.6–3.9 in) long and 5–18 mm (0.20–0.71 in) wide. Adult leaves are lance-shaped to curved, the same shade of green on both sides, 70–185 mm (2.8–7.3 in) long and 10–30 mm (0.39–1.18 in) wide, tapering to a petiole 5–22 mm (0.20 ...
A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally above ground and specialized for photosynthesis.Leaves are collectively called foliage, as in "autumn foliage", [2] [3] while the leaves, stem, flower, and fruit collectively form the shoot system.

Conocarpus erectus is usually a dense multiple-trunked shrub, 1–4 m (3.3–13.1 ft) tall, but can grow into a tree up to 20 m (66 ft) or more tall, with a trunk up to 1 m (3.3 ft) in diameter.
V. thapsus is a dicotyledonous plant that produces a rosette of leaves in its first year of growth. [3] [4] The leaves are large, up to 50 cm long. The second-year plants normally produce a single unbranched stem, usually 1–2 m tall. In the eastern part of its range in China, it is, however, only reported to grow up to 1.5 m tall. [5]
In plant taxonomy, which is the study of the classification and identification of plants, the morphology of plant's flowers are used extensively – and have been for thousands of years. Although the history of plant taxonomy extends back to at least around 300 B.C. with the writings of Theophrastus , [ 124 ] the foundation of the modern ...
On August 22, 2013, with the plant online at 98% power, two of the plant's main feedwater pumps tripped, causing a drop of the reactor water level. Operators inserted a manual SCRAM to shutdown the reactor prior to the third feedwater pump subsequently tripping. The loss of feedwater and sudden trip from the high power level caused the reactor ...
