Description
Roystonea lenis is a large palm which reaches heights of 20 metres (66 ft). Stems are grey-white and are usually 35–47 centimetres (14–19 in) in diameter. The upper portion of the stem is encircled by leaf sheaths, forming a green portion known as the crownshaft which is normally 2 m (6.6 ft) long. Individuals have about 15 leaves with 0.2–0.7 cm (0.079–0.276 in) petioles and 4–5.8-metre (13–19 ft) rachises; the leaves hang well horizontal. The 1 m (3.3 ft) inflorescences bear white male and female flowers. Fruit are 11.3–14 millimetres (0.44–0.55 in) long and 8.8–11.1 mm (0.35–0.44 in) wide, and black when ripe.[2]
gollark: See, it's important to recognize that distinction.
gollark: What do you mean you "perceive" time as discrete? You mean you *arbitrarily think so*, or what?
gollark: Quite a lot.
gollark: > The Planck time is the unique combination of the gravitational constant G, the special-relativistic constant c, and the quantum constant ħ, to produce a constant with dimension of time. Because the Planck time comes from dimensional analysis, which ignores constant factors, there is no reason to believe that exactly one unit of Planck time has any special physical significance. Rather, the Planck time represents a rough time scale at which quantum gravitational effects are likely to become important. This essentially means that while smaller units of time can exist, they are so small their effect on our existence is negligible. The nature of those effects, and the exact time scale at which they would occur, would need to be derived from an actual theory of quantum gravity.
gollark: Oh, no, never mind, that's not it.
