Aglaonema costatum, called the spotted evergreen, is a species of flowering plant in the genus Aglaonema, native to Bangladesh, Thailand, Peninsular Malaysia, Laos, Cambodia and Vietnam. [2] In these areas, the plant is typically found growing in the understory of tropical rain forests. [ 3 ]
The evergreen leaves are shiny, dark green with lighter undersides, and borne on short petioles. The two subspecies have different leaf shapes. The two subspecies have different leaf shapes. The inflorescence is a cluster of woolly white flowers with many short, whiskery stamens .
Prunus ilicifolia flowers. It is an evergreen shrub [4] or small tree approaching 15 metres (49 feet) in height, [12] with dense, hard leaves [4] (sclerophyllous foliage). The leaves are 1.6–12 centimetres (3 ⁄ 4 – 4 + 3 ⁄ 4 inches) long with a 4–25 millimetres (1 ⁄ 8 –1 in) petiole [12] and spiny margins, somewhat resembling those of the holly.
Evergreen and deciduous species vary in a range of morphological and physiological characters. Generally, broad-leaved evergreen species have thicker leaves than deciduous species, with a larger volume of parenchyma and air spaces per unit leaf area. [4] They have larger leaf biomass per unit leaf area, and hence a lower specific leaf area ...
Limoniastrum monopetalum is a small evergreen shrub, [2] [3] that has long thread-like and tufted fine roots, with ephemeral roots that are produced in a wet season and then vanish afterwards. The wide spread of the roots helps the plant withstand the high salinity conditions and they can also travel down to at least 50 cm to reach the water ...
Lophostemon confertus (syn. Tristania conferta) is an evergreen tree native to Australia, though it is cultivated in the United States and elsewhere. Common names include brush box, Queensland box, Brisbane box, pink box, box scrub, and vinegartree. [3]
Buxus sempervirens is an evergreen shrub or small tree growing 1 to 9 m (3 to 30 ft) tall, with a trunk up to 20 centimetres (8 in) in diameter (exceptionally to 10 m tall and 45 cm diameter [6]). Arranged in opposite pairs along the stems, the leaves are green to yellow-green, oval, 1.5–3 cm long, and 0.5–1.3 cm broad.
Studies of plant tolerance have only received increased attention recently, unlike resistance traits which were much more heavily studied (Fornoni 2011). Many aspects of plant tolerance such as its geographic variation, its macroevolutionary implications and its coevolutionary effects on herbivores are still relatively unknown (Fornoni 2011).
