400 l. crassulace.e (britten). [Sedum. 



tetragonous ; leaves few, very thick, glabrous, lanceolate or oblanceolate, 

 obtuse, 1-2 in. long, mode of attachment in our specimens uncertain. 

 Flowers erect or ascending, in few-flowered compact rounded cymes, on 

 slender peduncles. Calyx persistent, segments lanceolate, acute, about 

 1 line long. Petals oblong-lanceolate, acute, spreading, three times as 

 long as the calyx. Carpels oblong, glabrous, acuminate, normally 5 

 but often fewer by abortion. Squamulae membranous, linear, truncate, 

 about as long as the calyx.

The leaves have almost all fallen away from the specimens I have seen. 



2. S. Schimperi, Britten. Csespitose ; stems spreading, much 

 branched, glabrous, thick, leafy to the inflorescence ; leaves opposite, 

 entire, oblanceolate-spathulate, obtuse or rounded at the apex, rather 

 thick, much narrowed below. Flowers in terminal branched rather 

 dense rounded cymes. Calyx-segments deltoid-lanceolate, obtuse, 1 line 

 long*. Petals oblong-lanceolate, acute, twice as long aa the calyx. 

 Squamulae linear-lanceolate, as long- as the calyx. Carpels as in 8.

Much resembles the preceding in the flowers, but the leaves are quite different.

Calyx 6-10-fid or partite. Petals 6-10, lanceolate, free or connate 

 at the base and united with the filaments, acute. Stamens twice as 

 many as the petals, free or united with the petals, filaments filiform or 

 dilated at the base ; anthers ovate or didymous. Squamulae square or 

 linear, dentate or subentire. Carpels as many as the petals, immersed 

 at the base in the calyx-tube, lengthened into slender styles, with capi- 

 tellate stigmas. Ovules many. Follicles many-seeded. — Herbs or 

 shrubs, thick, fleshy, often acaulescent, emitting leafy branches, or with 

 leafy stems. Leaves alternate, thick, fleshy. Cymes paniculate, often 

 dense. Flowers white or yellow.
