It was larger than many other botany textbooks at the time, including a vast range of topics beyond the scope of most books on general botany. [14]

These plants, normally woody perennials, grow stems into the air, with their resting buds being more than 50 cm above the soil surface, [10] e.g. trees and shrubs, and also epiphytes, which Raunkiær later separated as a distinct class (see below). Raunkiær further divided the phanerophytes according to height as Megaphanerophytes ...
A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
In the fields of horticulture and botany, the term deciduous (/ d ɪ ˈ s ɪ dʒ u. ə s /) [1] [2] means "falling off at maturity" [3] and "tending to fall off", [4] in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit.
An individual flower is 5–6 mm (3 ⁄ 16 – 1 ⁄ 4 in) long and 8–11 mm (5 ⁄ 16 – 7 ⁄ 16 in) wide. Protandrous , bisexual flowers and male flowers exist on the same individual tree. The fruit is a smooth ( glabrous ), olive-like drupe which varies in shape from elongate oval to nearly roundish, and when ripe is 14–28 mm ( 1 ⁄ 2 ...
