[2] [4] They are commonly known as ivory palms, ivory-nut palms or tagua palms (/ ˈ t ɑː ɡ w ə, ˈ t æ ɡ-/); the scientific name Phytelephas means "plant ivory" or more literally, "plant elephant". This and the first two of the common names refer to the very hard white endosperm of their seeds (tagua nuts or jarina seeds), which ...
An early use of vegetable ivory, attested from the 1880s, was the manufacture of buttons.The material is called corozo or corosso when used in buttons.Rochester, New York was a center of manufacturing where the buttons were "subjected to a treatment which is secret among the Rochester manufacturers", presumably improving their "beauty and wearing qualities".

The ability to climb on surfaces varies with the plants variety and other factors: H. helix prefers non-reflective, darker and rough surfaces with near-neutral pH. It generally thrives in a wide range of soil pH with 6.5 being ideal, prefers moist, shady locations and avoids exposure to direct sunlight, the latter promoting drying out in winter.
Hedera helix adult leaves and unripe berries in Ayrshire, Scotland. On level ground ivies remain creeping, not exceeding 5–20 cm height, but on surfaces suitable for climbing, including trees, natural rock outcrops or man-made structures such as quarry rock faces or built masonry and wooden structures, they can climb to at least 30 m above the ground.
This image shows the development of a normal plant. It resembles the different growth processes for a leaf, a stem, etc. On top of the gradual growth of the plant, the image reveals the true meaning of phototropism and cell elongation, meaning the light energy from the sun is causing the growing plant to bend towards the light aka elongate.
Poison ivy is a type of allergenic plant in the genus Toxicodendron native to Asia and North America. Formerly considered a single species, Toxicodendron radicans, poison ivies are now generally treated as a complex of three separate species: T. radicans, T. rydbergii, and T. orientale.
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 ...
Plant-animal interactions are important pathways for the transfer of energy within ecosystems, where both advantageous and unfavorable interactions support ecosystem health. [ 1 ] [ 2 ] Plant-animal interactions can take on important ecological functions and manifest in a variety of combinations of favorable and unfavorable associations, for ...
