ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION, m 
sessile, yellow to orange, ^ inch across. Sepals green ; linear, blunt, and terete 
in upper half ; widening below to a broad base. Petals nearly twice the sepals, 
linear-lanceolate, apiculate, yellow to orange, wide-spreading. Stamens spreading, 
nearly equalling the petals, yellow, anthers ovate. Scales white, broader than 
long. Carpels at first erect, spreading later, yellow, often becoming orange or 
red, spreading widely in fruit. 
Flowers July. Hardy. 
Habitat. — Siberia, Mongolia, Manchuria, China, Japan. 
5. Maximowiczii Kegel is, according to Maximowicz [loc. cit.), whose 
knowledge of the North Asiatic Sedums was unequalled, the form of 
Aizoon found in cultivation in Japan — very tall, large-leaved, and 
large-flowered. Recent Japanese writers agree in this view. 
5. Woodwardii N. E. Brown is undoubtedly referable to S. Aizoon. 
The type specimen in Kew Herbarium is poor, but by the kindness of 
the late Mr. Robert Woodward, in whose garden the plant appeared 
as a seedling, I received fine specimens taken from the original root. 
These represented a rather broad-leaved form, lax from growing in 
rich soil in half shade ; each of the special characters — such as the 
rather obtuse dentition, obliquely obovate leaves, and very lax in- 
florescence — on which the species was founded, has disappeared when 
the plant has been grown under ordinary conditions in my garden, and 
the plant as now growing differs in no way from ordinary S. Aizoon. 
(See Journ. of Boi., 55, 215.) 
Several varieties of S. Aizoon have been described, based on differ- 
ences in stem and leaf characters, such as var. latifolium Maximowicz, 
"Flor. Amurensis," 115, and Regel, "Flor. Ussuriensis " 70, a small 
branched form with very large leaves ; var. saxatilis Nakai, " Flor. 
Koreana," small and branched with narrow leaves ; and var. floribtinda 
Nakai loc. cit. , very tall and narrow-leaved. These may be of importance 
locally as geographical forms, but in the garden a continuous range is 
found, among which it is not possible to select any as outstanding and 
worthy of varietal names in a botanical sense. My collection came 
* from some fifty different garden sources, ranging from Japan on the 
east to Canada on the west. Among them the chief variations observed 
were as follows : — 
(1) Habit. — Some very erect, some rather diffuse. 
(2) Branching. — A strong stem will often bear many axillary 
branches, and any stem will branch if the growing point is injured, but 
some forms were branched invariably. 
(3) Inflorescence. — Typically terminal, very compact, involucrate ; 
but the cyme-branches may be lengthened, pl-oducing with the en- 
larged leaf-like bracts a lax fiat inflorescence 6 inches across ; or the 
terminal flower-head, in conjunction with others borne on axillary 
branches, may form a hemispherical inflorescence half a foot across. 
(4) Leaf -form. — Outline from linear-lanceolate to broadly ovate 
(see fig. 56), and dentition from obscure to bold, and from blunt to 
acute. 
(5) Pigmentation. — From bright green in stem and leaf, clear yellow 
in flower, and bright green in fruit, to dark red in stem, dark green in
