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, shdpe and arrangement of leaf. Many of these 

 match described varieties fairly weU, 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 

 " Monographic de quelques Sedum " in "Memoires de la Society 

 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. Telefhium 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 m 

 the leaves and stems, and the substitution of ternate for opposite 

 leaves. These find their most marked expression in the noble var. 

 atropurpureum, referred to below. 



Description —A large glabrous herbaceous perennial. Rootstock thickened. 

 i?oo?5 a bunch of ca^ot-lfke tubers. Stems 1-3 feet, erect, smooth, round green 

 or red unbranched. or branched near summit, annual. Leaves usual y dark 

 Seen sessile clasping, usually opposite, often ternate. sometimes alternate 

 Sen? siei^is o^the^same plLt often showing all three of these vanataons 

 Iroadly ovate, blunt. sUghtl/and irregularly to°thjd J-ynches ^X 

 to two-thirds as broad. Inflorescence composed of terminal and also lateral 

 densTcoirmbs ; stems of lower corymbs long ; ultimate pedicels slender, longer 

 than th^flowers. Flowers 5-parted, crowded, greemsh-white, | inch across. 

 BuSs ovoid, ribbed, blunt, sfpals green, fleshy, lanceolate to deltoid acute, 

 ftoils long as the petals, tube short. Petals ovate-lanceolate, rather acute 

 greenth whitl Starr^ens shghtly exceeding the petals, filaments white, anthers

 erect, greenish, non-contiguous on inner face, equalhng the petals. 

 Flowers August-September. Hardy. 

 Habitat.— Widespread in Europe ; Caucasus. 



var. atropurpureum hort. 

 Leaves and stems deep purple. This definition covers a nuniber 

 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. Asmaller form is figured by Masters ("Hardy Sedums, I.e.).
