ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 275 
shoots a couple of inches long and flower-stems three inches high to 
strong forms with shoots 9 inches long and flower-stems of a foot ; 
(2) leaf-colour, bright green, dark green flushed with red, or glaucous ; a 
form brought from Bulgaria by Sir Josslyn Gore-Booth is so glaucous 
as to be almost white ; (3) flower-colour, this varies less, being either 
of the typical whitish hue or else golden yellow. Among this variable 
set I have found it futile to attempt to distinguish varieties, of which 
several have been described, such as chrysanthiim and chloranthum of 
Jeanbernat and Timbal-La grave, and S. Verloti of Jordan. 
Frequent in cultivation but generally under erroneous names 
or synonyms, such as collinum, elegans, elongatum, Forsterianum, 
montanum, ochroleucum, reflexum, stenopetahtm, virens. 
Its name anopetalum is descriptive of the characteristic upward 
direction of the petals.

The only representative in America of the rupestre group which 
is so characteristic of the European Sedum flora. Most resembles 
S. reflexum, but the shoots, though sometimes elongate, do not creep, 
and are normally very short and erect. The leaves are blunter and 
of a duller surface ; under the microscope this is seen to be due to 
the surface being more distinctly cut up into polygonal spaces, in 
which hemispherical papillae are often placed ; when the leaves are 
tinged purple, as is frequent, the colour resides in these prominences. 
In flower the species differs from reflexum in its shorter stem, more 
flattened leaf, inflorescence erect in bud and flatfish in both bud and 
fruit, and the petals, which are uniformly 5 in number, are much 
more acute. 
Description. — A tufted, glabrous, evergreen perennial. Stents few, erect 
or ascending, barren shoots short (about i inch long), leafy ; flowering shoots 
4 to 6 inches. Leaves scattered, glaucous, or dull green, or flushed dull purple, 
minutely papillose, i to | inch long, somewhat flattened, linear- lanceolate, entire, 
blunt, curved upwards, very shortly spurred, imbricate around the growing point ; 
those of the flowering stem similar, rather larger, less crowded. Inflorescence 
I to 2 inches across, of several forked branches with flowers in the forks, flattish, 
compact ; in strong plants elongate (3 inches long or more), by production of 
axillary branches below the main inflorescence. Buds ovate-oblong, pointed. 
Flowers short- stalked, ^ inch across. Sepals fleshy, lanceolate, rather blunt, 
pale green, flat on face, rounded on back, separate nearly to the base. Petals 
lanceolate, acute, patent in upper part, bright yellow, grooved on face, with a 
greenish keel on back, twice the sepals. Stamens spreading, shorter than the 
petals, filaments yellow, anthers orange. Scales very small, orange, notched, 
broader than long. Carpels slender, nearly erect, greenish yellow, tlie tips 
diverging in fruit.
