 at the apex, unequal, about a line long ; petals twice longer, greenish 

 white, narrowly oblong, obtuse: stamens 10; scales at the base of 

 the carpels purple, oblong-obovate : carpels purple, divergent, equalling 

 the petals. — In the crevices of rocks ; Norogachi (374). 



Sedum filiferum. Perennial, csspitose, glabrous, the branching 

 rootstock bearing rosettes of numerous spatulate leaves, 4 to 8 lines 

 long, which are abruptly acute and attenuate into filiform appendages

 cending, about 4 inches high, bearing an open cyme ; pedicels 3 or 4

 to G lines long, reduced above to linear hirsute bracts : flowers 1 to 3 

 in the axils, on pedicels 2 lines long or less . calyx 5 lines long, nar- 

 row in flower, gibbous, hirsute on the veins, the dorsal lobe produced ;
