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) flow er -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 chrysanthum 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, ochroleticum, reflexum, stenopetahim, 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 flattish in both bud and 

 fruit, and the petals, which are uniformly 5 in number, are much 

 more acute. 



Description. — A tufted, glabrous, evergreen perennial. Stems 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 J 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 forto, 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, the tips 

 diverging in fruit.
