_Aloe Peglerae_ is quite a common plant in parts of the Transvaal, and
may be found in quantities on the stony hills of the Magaliesberg round
Pretoria. The species was first described by Dr. S. Schönland in 1903
from specimens collected by Miss Alice Pegler near Rustenburg. The
peculiar lax arrangement of the leaves is very characteristic, and Miss
Pegler not inaptly compared its appearance to a loose cabbage.
In the description accompanying Plate 107 (_Aloe comosa_) we described
the method in which the flowers mature. _Aloe Peglerae_, as far as we
have observed, is an exception to this general rule, as the style is
exserted with the filaments and does not wait until the filaments are
withdrawn, and the perianth withers before protruding.
Our plate was prepared from specimens which flowered at the Division of
Botany, Pretoria.
DESCRIPTION:--_Plant_ almost acaulescent with a dense rosette of leaves.
_Leaves_ curved, about 28 cm. long, 5·5 cm. broad, below lanceolate,
ending in a short spine, almost flat on the upper surface, slightly
convex on the lower surface, faintly keeled and spiny on the back in the
uppermost third, with the margins spiny; the spines on lower portion of
leaf about 1 mm. long and about 5 mm. apart, becoming 5 mm. long and 1·5
cm. apart in the upper part of the leaf. _Peduncle_ solitary from the
middle of the leaf rosette, about 1·2 cm. in diameter and covered with
ovate long-acuminate erect membranous bracts. _Flower spike_ about 18
cm. long, up to 8 cm. in diameter; flowers at first reddish, becoming
greenish-white at maturity. _Outer perianth-segments_ 2·5 cm. long, 6
mm. broad, oblanceolate, with the apex slightly recurved, 3-nerved;
inner segments 2 cm. long, 8 mm. broad, oblong, 1-nerved. _Stamens_ at
length long exserted; filaments dark purple above, greenish below,
linear. _Ovary_ 5 mm. long, ellipsoid; style 4·2 cm. long, cylindric,
exserted with the stamens; stigma small (_National Herb. Pretoria_, No.
2846).
