means of which it has been propagated and distributed. 
Other plants identical with these have been received 
since at La Mortola from the Botanic Gardens in Palermo 
and Paris under the name of A. asperruna. One of the 
plants derived from the original specimen flowered at La 
Mortola in June, 1911, and provided the material on which 
our figure is based. Our plant agrees well with the 
description of A, marmorata given by Baker in his Hand- 
book of the Amaryllideae, p. 179: his remark, ‘‘ between 
A. Scolymus and A. americana,” well expresses its characters. 
The leaves are glaucous, almost white, and only become 
greener in dying off on the flowering plant. They are 
extremely rough, especially on the underside and near the 
point; the marginal and end spines are also tubercular and 
rough. The Indians are said to make use of the leaves in 
veterinary medicine. 
The position of A. marmorata is not altogether clear. 
From the leaves it might be considered a member of the 
Americanae of Baker, but the small bright yellow flowers 
preclude this and suggest a closer affinity to the species 
allied to A. Willdingii, Tod., though here again A. marmorata 
differs as regards the arrangement of its flowers on the 
branches. 
Description.—Shrub; stem 0; rosette simple, without 
suckers or offshoots, 2 yards in diameter and 1 yard high, 
with about thirty leaves. Leaves spreading from the base, 
recurved from the middle and with a slightly inflexed tip, 
lanceolate or oblanceolate-spathulate, 40-44 in. long, above 
the middle 10-11 in. broad, hence gradually narrowed to 
a channelled point ending in a conical, greyish brown, very 
rough spine, ? in. long, not decurrent; constricted towards 
the base and about 53 in. broad at the neck, about 3 in. 
thick at the base, convex on both sides, but very markedly 
and almost broadly keeled on the underside, gradually 
thinner above, broadly channelled and with the margins 
erect and somewhat undulate, much repand between the 
large irregular spines, very glaucous or almost white or 
with a bluish tint, becoming paler and greener only before 
decaying, very rough everywhere, especially on the under- 
side and near the top; marginal spines from a broad horny 
base, cuspidate-uncinate, brown, rough, rising from a broad
