In my plant the leaves faded in autumn, but remained withered on the 

 branches, giving them a shaggy appearance. 



Description. — A minute, glabrous, tufted perennial. Stems rooting below, 

 ascending, barren shoots very short, densely leafy, flowering shoots 1-2 inches, 

 with less dense leaves. Leaves opposite, sessile, entire, obovate-cuneate, blunt, 

 very fleshy, flat on face, rounded on back, dotted with red, J inch long by -5^5^ inch 

 broad. Inflorescence a small, terminal, few-flowered, cyme. Buds angular. 

 Flowers \ inch across, with pedicels about equalling the calyx. Sepals resembling 

 the upper leaves, separate almost to the base. Petals spreading, but not 

 widely, greenish with a reddish keel, ovate-lanceolate, blunt, 1^-2 times the 

 sepals. Stamens equalling the sepals, filaments green, anthers pale red. Scales 

 pale orange, semiorbicular, emarginate, conspicuous. Carpels green, erect, 

 shorter than the stamens. 



Flowers May. Hardy. 



Habitat. — Asia Minor, Caucasus. 



A little plant of no horticultural value. Very rare in cultivation, 

 but it is grown (as S. tenellum M. B., also a small Caucasian species, but 

 differing in its linear terete leaves, &c.) by Regel and Kesselring of

Fig. 113. — 5. Stevenianum Rouy and Camus. 



Petrograd, from whom I received it. Distinguished by its broad- 

 topped leaves and cup-shaped, greenish-white flowers tinged with red. 



My plant nearly died before I got it drawn, which accounts for 

 the fragmentary character of fig. 113. Owing to the war I was not 

 able to procure further material. 



The name commemorates the original describer, who named it S. 

 roseum, a name already occupied.

A curious and very distinct species, unmistakable in its winged, 

 triangular stem, ternate leaves, and large, greenish-red flowers. 



Description. — A straggling, light-green evergreen perennial. Stems weak, 

 smooth, green, ascending, unbranched, 6 to 9 inches high, triangular (occasionally 

 square), with the angles winged, dying back after fruiting to near the base, 

 young shoots arising from the lower part. Leaves entire, sessile, ternate 

 (occasionally in fours), often alternate below the inflorescence, spathulate in 

 lower part to orbicular in upper part of stem, often notched at apex, shorter 

 than the intemodes, about J inch long, shortly spurred, rather thin. 

 Inflorescence few-flowered, slightly branched, leafy. Buds oblong, blunt, 

 greenish. Flowers stalked, J inch across when fully expanded. Sepals semi- 

 erect, very unequal, green, leaf-like, oblong- lanceolate, blunt. Petals greenish
