		These plants may grow in the form of a small, stemless rosette of fleshy leaves to a huge tree 30 feet in height.
		The residue from the leaves of A. vera is known as Barbados Aloes and Curacao Aloes.
		The thick, fleshy leaves are able to store great amounts of water during a rainy season and are therefore able to survive throughout drought.

	Garden Botany
		Stolon: A horizontally growing stem at ground level with leaves along its length (not just a rosette at the end, as in a runner) and adventitious roots that form at the nodes.
		They usually have leaves, and their growing tip or shoot apex has small stubs on its side, which develop into leaves.
		The vascular system is made up of xylem, which transports water and nutrients from the roots to the leaves, and phloem, which transports food to the roots and the stem.

	Rosettes - Wikipedia, the free encyclopedia
		A botanical term, referring to a circular arrangement of leaves (see: Rosette (botany)).
		A symmetrical configuration of 3 or more similar bodies in orbit around their center of mass (see: Klemperer rosette).
		A small, circular, device that can be awarded with medals (see: Rosette (decoration)).

	AZ Master Gardener Manual: Leaves
		Rosulate arrangement is one in which the basal leaves form a rosette around the stem with extremely short nodes.
		The base of the petiole is attached to the stem at the node.
		Alternate or spiral leaves are arranged in alternate steps along the stem with only one leaf at each node.

	Hawaiian silversword alliance, UH Botany
		Silverswords may grow for 50 years or more as a compact rosette before they initiate a flowering stalk in a rapid bolting process that reaches full development in just a few weeks.
		The leaves are clothed with a dense layer of silvery hairs and are arranged in a parabolic rosette that focuses the rays from the sun and elevates the temperature of leaves near the shoot tip as much as 20 degrees C above the surrounding leaves.
		In the waning twilight of life, as seed development proceeds, the reserves accumulated in the rosette over a period of many years are mobilized into the fruiting stalk, and the once succulent leaves become flacid.

		Erect, single-stemmed and monocarpic or rarely branched and polycarpic rosette shrub with epigeal or nearly epigeal rosettes; flowering stems up to nearly 3 m tall.
		This species is found on the upper slopes of Mauna Kea, Hawai'i and the summit area of Haleakala, East Maui in high elevation scrub or alpine cinder desert habitats ranging in elevation from 2,125 to 3,750 m.
		It occurs in sites receiving about 50-175 cm of annual precipitation.
