When characteristic, S. purpureum and 5. Fabaria are easily 

 distinguished, but there are many plants which one hesitates to refer 

 to one form or to the other — ^whether this is due to crossing or not 

 I cannot offer an opinion. The " wild " British plants which I have 

 grown have all been Fabaria, but I do not attempt to go into the 

 question of the distribution in the British Isles of the two forms. 

 The confusion which seems fated to hang over the Sedums is here 

 especially marked, as, for instance, when one receives from one of the 

 ablest of English field botanists roots of the Japanese 5. alboroseum 

 as a native Telephium form from woods in Sussex ! 



As in the case of its near ally S. maximum, a large number of 

 varieties of 5. Telephium have been described, particularly by French 

 botanists, and a good account of these will b6 found in Rouy and Camus, 

 " Flore de France," vol. vii. For reasons stated in the Introduction to 

 the present paper (p. 15) and under S. maximum on p. 81, no attempt 

 is made here to enter into a discussion of these. The reader seeking 

 information regarding them should consult Boreau, " Monographie 

 de quelques Sedum," Mem. Soc. Acad, d' Angers, vol. xx.. 1866 ; Masters 

 in Gard. Chron., 1878, ii. ; Rouy and Camus, " Flore de France," vol. vii, 

 1901 ; and the beautiful coloured plates in Jordan and Fourreau, 

 " Icones ad Floram Europae," vol. i. 1866-8. It may be said that 

 they belong almost altogether to S. purpureum, not to 5. Fabaria. 

 Among the garden forms variation is very noticeable in the height 

 and colour of stem ; in the arrangement, size, shape, dentition, and 

 colour of leaves ; and in the- size, shape, and colour of inflorescence 

 and flower. 5. Telephium seems to vary much more in directions 

 other than towards maximum, than S. maximum does, except towards 

 Telephium. Nevertheless, the presence of many intermediates is 

 discouraging in the search for satisfactory varieties. In the case 

 of Telephium, confusion is very probably produced in gardens by the 

 natural crossing of varieties, as the species tends to produce itself 

 from seed more freely than the majority of Sedums. 



Var. Border! Rouy and Camus. 



Of the forms of S. Telephium found in gardens which I have 

 succeeded in identifying with described varieties, the one which appears 

 most satisfactory, as maintaining a distinct and uniform facies, is 

 5. purpureum var. y Borderi Rouy and Camus, " Flore de France," 

 7, 103-4 {Anacampseros Borderi Jordan' and Fourreau, " Brev. Plant. 

 Nov.," fasc. i. 30, and " Icones Plant. Eur.," t. 96), which has leaves 

 deeply and irregularly toothed and distinctly stalked (fig. 38, a) . This 

 was received from several garden sources, mostly named var. 

 carpaticum (S. carpaticum Reuss), which is somewhat similar.
