ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 8l 
no variation. Since then I have had self-sown seedlings showing 
every combination of the characters of the two species as regards 
colour of flower, size, shape and arrangement of leaf. Many of these 
match described varieties fairly well, so that, for horticultural purposes, 
it seems futile to devote space to many of the latter. Descriptions 
of a large number of these segregates will be found in Boreau's paper, 
" Monographie de quelques Sedum " in " Memoires de la Societe 
Academique d'Angers," 20, 1866. A good account of the forms found 
in France, to the number of 19, is given in Rouy and Camus, " Flore 
de France," 7, p. 96. Very fine coloured illustrations of many of 
the forms of this and other of the equally variable S. Telephium are 
published in Jordan and Fourreau, " Icones ad Floram Europae," 1, 
1866-68, as species of a segregate genus Anacampseros. 
I have had in cultivation a large series of maximum forms and 
hybrids, received under many names from many sources, and have 
not succeeded in satisfying myself how far variation in character, 
such as alternate instead of opposite leaves, or reddish pigment in 
the flower is inherent in S. maximum or due to Telephium influence. 
As regards variation in undoubtedly pure maximum, its most striking 
manifestation is in the development of brownish-purple pigment in 
the leaves and stems, and the substitution of ternate for opposite 
leaves. These find their most marked expression in the noble var. 
airopurpureum, referred to below. 
Description. — A large glabrous herbaceous perennial. Rootstock thickened. 
Roots a bunch of carrot-like tubers. Stems 1-3 feet, erect, smooth, round, green 
or red, unbranched, or branched near summit, annual. Leaves usually dark 
green, sessile, clasping, usually opposite, often ternate, sometimes alternate 
(different stems of the same plant often showing all three of these variations), 
broadly ovate, blunt, slightly and irregularly toothed, 2-3 inches long by half 
to two-thirds as broad. Inflorescence composed of terminal and also lateral 
dense corymbs ; stems of lower corymbs long ; ultimate pedicels slender, longer 
than the flowers. Flowers 5-parted, crowded, greenish-white, f inch across. 
Buds ovoid, ribbed, blunt. Sepals green, fleshy, lanceolate to deltoid, acute, 
J to ^ as long as the petals, tube short. Petals ovate-lanceolate, rather acute, 
greenish- white. Stamens slightly exceeding the petals, filaments white, anthers 
yellow. Scales yellow, linear, notched, twice as long as broad. Carpels stout, 
erect, greenish, non-contiguous on inner face, equalling the petals. 
Flowers August-September. Hardy. 
Habitat. — ^Widespread in Europe ; Caucasus. 
var. atropurpureum hort. 
Leaves and stems deep purple. This definition covers a number 
of forms, varying in size, habit, and pigmentation. The most striking 
of them is an extremely vigorous plant, three feet or more in height, 
leaves usually ternate and up to 5 inches long by 3 inches broad, 
stem and leaves dark purple, flowers pink. It is not uncommon in 
gardens. A smaller form is figured by Masters (" Hardy Sedums," I.e.).
