2 (two) is a number, numeral, and glyph. It is the natural number following 1 and preceding 3.
Tillandsia is a genus of around 650 species of evergreen, perennial flowering plants in the family Bromeliaceae, native to the forests, mountains and deserts of northern Mexico and south-eastern United States, Mesoamerica and the Caribbean to mid Argentina. Their leaves, more or less silvery in color, are covered with specialized cells (trichomes) capable of rapidly absorbing water that gathers on them.
They are also commonly known as airplants because of their natural propensity to cling wherever conditions permit: telephone wires, tree branches, barks, bare rocks, etc. Their light seeds and a silky parachute facilitate this spread. Most Tillandsia species are epiphytes – which translates to 'upon a plant'. Some are aerophytes, which have a minimal root system and grow on shifting desert soil. Due to the epiphytic way of life of the plants the peculiarity arises that these bulbs do not lie in the ground, but hang in the air on branches.
A branch (UK: /ˈbrɑːntʃ/ or UK: /ˈbræntʃ/, US: /ˈbræntʃ/) or tree branch (sometimes referred to in botany as a ramus) is a woody structural member connected to but not part of the central trunk of a tree (or sometimes a shrub). Large branches are known as boughs and small branches are known as twigs. The term "twig" often refers to a terminus, while "bough" refers only to branches coming directly from the trunk.
Due to a broad range of species of trees, branches and twigs can be found in many different shapes and sizes. While branches can be nearly horizontal, vertical, or diagonal, the majority of trees have upwardly diagonal branches. A number of mathematical properties are associated with tree branchings: they are natural examples of fractal patterns in nature, and, as observed by Leonardo da Vinci, their cross-sectional areas closely follow the da Vinci branching rule.
