Family Aloaceae

Trees , shrubs , and succulents, perennial , simple to sparsely branched, rhizomatous , some tuberous-thickened. Leaves simple, alternate, usually crowded at bases of stems or ends of branches, sessile; blade fleshy , margins often prickly, venation parallel. Inflorescences terminal , axillary , or lateral , spicate , racemose, or paniculate . Flowers 3-merous, short- to long-pedicellate, rarely sessile; perianth red, brown, yellow, orange, or whitish; tepals petaloid , connivent or connate basally to almost entirely into tube , sometimes fleshy; stamens sometimes 3, usually 6, exserted or included ; anthers dorsifixed , dehiscence antrorse ; pollen grains monosulcate; ovary 3-carpellate, placentation axile , usually with septal nectaries; style terminal; stigmas punctate , discoid , or 3-lobed. Fruits capsular , rarely baccate , dehiscence loculicidal, apical. Seeds usually winged or flattened.

Genera 5, species ca. 700 (1 genus, 2 species in the flora ) : all introduced ; Africa, Madagascar, Arabia, and Atlantic islands.

Aloaceae are closely related to and included by some authors in Liliaceae.

The juice of some Aloe species is used to make a purgative called bitter aloe; active ingredients include aloin and other anthraquinones . Additionally, the thick, mucilaginous gel of some species is widely used to treat minor thermal burns , itching, and sunburn.[1]

Genus Aloe

Plants succulent, shrubby or arborescent , scapose . Stems erect , clambering or ascending , branched or not. Leaves succulent, crowded, often rosulate or distichous; blade margins spiny-toothed or entire. Inflorescences axillary or terminal , paniculate to more often racemose, dense, bracteate . Flowers usually nodding ; perianth red to yellow; tepals connate basally to almost entirely into tube ; stamens 3 or 6; style slender; pedicel not articulate . Capsules papery to woody. x = 7.

Species 300 or more: introduced ; primarily s and tropical Africa; also Madagascar, Arabian peninsula, and Atlantic islands (Madeira , Canary, and Cape Verde) ; naturalized in the Mediterranean region, India, and China.[2]

Habitat

Ecology: Widely distributed and sometimes abundant on Soqotra and Samha; mainly in dry areas; on flat or gentle slopes , primarily on limestone pavement but occasionally on sandy plains or granite mountains. Altitude of sea-level to 900 m .

Delicate, sometimes apparently annual , plants with narrow stems found at high altitudes in the Haggeher mountains have been recognised as A. forbesii. However, there are many intermediates with typical A. perryi and so we have not found it possible to give them any formal status here. Flowers in summer and comes into new leaf after the least rain.[3]
