• Aloe compressa H.Perrier

Description: Aloe compressaSN|15240]]SN|35393]] is a small solitary species, without suckers, and stemless or very short-stemmed The 15-20 leaves are distichous (placed in a double row lying over each other and forming a flattened 'fan'), grey or blue green 12-15 cm long, 5 cm broad. This small aloe was first described in 1926 and is much in demand, for it is one of the very few species with two-ranked leaves, as in Aloe plicatilis and Aloe suprafoliataSN|35393]]SN|15240]]. The tall, unbranched inflorescence has small; white flowers.
Derivation of specific name: The specific epithet compressa comes from Latin, meaning 'pressed' and refers to the laterally compressed (two-line) leaf arrangement.

Margin toothed, teeth flattened up to 2 mm long, green orten with a red tip and 4-5mm apart, closely set near base, wider apart upwards.
Inflorescence: 60-70 cm tall, simple (or with one branch) with 40-60 flowers clustered at the tip. Stem very long with 15-20 white, triangular-acute, bracts. Raceme dense, almost oval, (7-8 long and 6 cm in diameter). Bracts white, 20-24 mm long, 10-17mm broad. Pedicels 1-2 mm long.
Flowers: Perianth white (or pink), 25-33 mm long straight, nearly triangular.
