ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 159 



Description. — A small, erect, glaucous evergreen sub-shrub, 6-8 inches high. 

 Roots fibrous. Stem smooth, round, dull red mottled and dotted with grey, bare 

 below, much branched, branches spreading. Leaves alternate, crowded, sessile, 

 linear-fusiform, sub-terete, patent or refiexed, glaucous, blunt, J inch long. 

 Inflorescence compact, convex, i inch across, very leafy. Buds tapering, slender, 

 blunt, often curved. Flowers \ inch across, pedicels very short. Sepals slightly 

 unequal, green, very fleshy, oblong-tapering, blunt, slightly prolonged below 

 point of insertion. Petals quite free, lanceolate, acute, patent or recurved, 

 white with a slight greenish keel, more than twice the sepals. Stamens nearly 

 equalling the petals, filaments white, anthers red. Scales minute, quadrate, 

 yellowish, with a blunt notch. Carpels green, erect, shorter than the stamens, 

 with long slender styles. 



Flowers January-February (gentle heat). Not hardy. 



Habitat. — No doubt, Mexico. 



Received from New York Botanic Garden labelled S. Bourgaei 

 No. 2. Also from Haage und Schmidt, of Erfurt, under the name 

 S. farinosum, a misnomer ; S. farinostim Lowe is a small Madeiran 

 plant related to 5. album ; S.Jarinosum Rose is a flat -leaved Mexican 

 plant, with no affinity to the present species (see p. 141). 



Named from the grey colour of the plant.

Ten species fall in here, coming from many different parts of the 

 world. 5. ternatum and 5. Nevii from the United States, are allied, 

 as are also 5. moranense and 5. Liebmannianum, from Mexico. The' 

 Chinese S. Chaneti stands quite apart. The remainder are small 

 plants not closely related.

A distinct little plant which, in the arrangement and characters 

 of flowers, shows its affinity to its ally 5. Nevii, which inhabits much 

 the same area of North America. It is well distinguished among 

 the hardy Sedums by its broad, entire leaves arranged in threes 

 (from which character it takes its name) , and largest near the top 

 of the barren shoots, and white flowers with the parts in fours — the 

 latter an almost unique feature in the genus, if we except the section 

 Rhodiola.
