ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 107 



The figure (fig. 53), such as it is, conveys an idea of the appearance 

 of the plant, the barren shoots being drawn from the living plant, and 

 the inflorescence added from the plate in " Gartcnflora." 



Apparently the leaves are irregular in their arrangement. Rudolph 

 and Maximowicz say they are alternate ; so does Ledebour {Fl. 

 Rossica, 2, 182). Regel figures them as opposite, but says alternate 

 in the accompanying description. In Miss Willmott's plant they 

 are opposite. 



Named from the lilac-glaucous hue of the leaves. 



SECTION IV.— GIRALDIINA. 



[Section Giraldiina Diels in Englcr's Boi. Jahrb., 36, 

 Beibl. 82, p. 48, 1905. 



Founded to include two Chinese species — 5. Scallanii Diels and 

 another undescribed. Allied to section Telephium, but differing 

 especially in possessing only five stamens. Neither species is in 

 cultivation.] 



SECTION v.— AIZOON. 

 Section Aizoon Koch, Synopsis, 259, 1836. 



Perennial. Rootstock thickened, roots slender. Stems annual 

 (except 5. hyhridum). Leaves flat. Flowers hermaphrodite, 5-parted, 

 bright yellow. Hardy East Asiatic plants. 



A small and compact group confined to N. and N.E. Asia. The 

 species vary considerably in habit, from tall and erect to creeping, 

 but the flowers, and in most cases the leaves, are very similar. Seven 

 out of the nine species are in cultivation. The two not in cultivation 

 are 5. Sikokianum Maxim., resembling a slender S. kamtschaticum, 

 and S. Yabeanum Makino, the only one of the section with entire 

 leaves ; both are natives of Japan. 



Aizoon Linn. kamtschaticum Fisch. and Meyer. 



Selskianum Regel. floriferum Praeger. 



Middendorffianum Maxim. hyhridum Linn. 

 Ellacombianum Praeger. 



Maximowicz divided S. hyhridum from the rest by its fruiting 

 carpels " lanceolati basi connati erectopatuli," those of the others 

 being " oblique ovati ad ■*- imam v. ultra connati indeque stellato- 

 patentes." In fig. 54 the full-grown fruit of the species in cultivation 

 has been drawn (excepting S. Selskianum, of which good fruit was not 

 available) , one carpel being removed to show the amount by which 

 they are connate. It will be seen that the characters used by Maxi- 

 mowicz are evident, but that they are not at all striking, a well-marked 

 gradation being observable ; this gradation does not accord well with 

 characters of flower, stem, and leaf. The group, indeed, does not
