252 CRASSULACE^. Till^a. 



Stems 1-2 inches long, branching towards the base, and rooting in the mud. Leaves 

 2-3 lines long, spreading and somewhat recurved, their bases uniting round the stem. 

 Flowers about the size of a pin's head, on short pedicels. Sepals oblong, obtuse, united at 

 the base. Petals oblong, obtuse, white. Stamens shorter than the petals : filaments slender : 

 anthers roundish. Hypogynous scales none ? Carpels membranaceous, slightly united. Seeds 

 oblong ; the testa crustaceous, striate and dotted. Albumen very thin. Embryo conformed 

 to the seed : cotyledons short : radicle thick. 



On the banks of the Hudson one or two miles north of Peekskill {Dr. Mead). Very nearly

2. SEDUM. Linn. ; Endl. gen. 4622. STONECROP. 



[ From the Latin, scdo, to sit; the plants of this genus appearing to sit on naked rocks.] 



Sepals 5 (sometimes 4 - 8), more or less united at the base, often resembling the leaves. 

 Petals distinct, mostly spreading. Stamens twice the number of the petals. Carpels as 

 numerous as the sepals, many-seeded, with a scale at the base of each. — Herbaceous or 

 rarely suffrutescent plants, mostly branching from the base. Leaves alternate or scattered, 

 sometimes opposite or verticillate, usually crowded on the sterile branches. Flowers cymose. 



1. Sedum telephioides, Michx. American Orpine. 



Leaves flat, ovate or oval, attenuate at the base, rather acute, somewhat toothed, smooth ; 

 stem erect; cymes paniculate-corymbose, densely flowered ; stamens 10, scarcely exceeding 

 the ovate-lanceolate petals. — Michx. jl. \.p. 277; Pitrsh, fl. 1. p. 324; Ell. sk. 1. p. 529; 

 Torr. Jl. I. p. 464; DC. prodr. 3. p. 402; Torr. <^ Gr. Jl. N. Am. 1. p. 558. 



Perennial. Stem about a foot high, simple, leafy. Leaves about an inch and a half long, 

 smooth and fleshy, broadly oval, obtusely toothed. Cymes compound, crowded, with small 

 leafy bracts interspersed. Sepals lanceolate-obtuse. Petals elliptical-oblong, pale purple, 

 twice as long as the calyx. 



Shore of Seneca Lake {Prof. J. Hall). I have not seen the plant from this locality, and 

 it may possibly be the following, which it greatly resembles. 



2. Sedum Telephium, Linn. Orpine, or Live-forever. 



Leaves flat, oblong and oval, attenuate at the base, toothed, smooth ; stem erect ; cymes 

 corymbose ; stamens shorter than the corolla. — Engl. hot. t. 1319 ; DC. plant, grass, p. 92, 

 and prodr. 3. p. 402. 



Diflers from the preceding chiefly in the more obtuse leaves and shorter stamens. 



Rocks ; Catskill Mountains, particularly near the Mountain House. In fields, Orville, 

 Onondaga county {Dr. Bradley). A naturalized plant of European origin, and very common 

 in gardens.
