154 . PITTONTA. 
SEDUM DIVERGENS. Annual, glabrous, 2—3 inches high, 
erect-spreading, with numerous divergent branches: leaves 
scattered, fleshy, 1—2 lines long, narrowly oval or oblong, 
obtuse, sessile by a broad base : flowers large (4 lines broad), 
solitary or in a divergent pair at the ends of the branches, 
white or faint rose-color; sepals lanceolate, half as long as 
the oblong-linear obtuse petals: fruit unknown. 
HYPERICUM PARVULUM. Perennial: stems many, erect from 
a decumbent or somewhat creeping and stoloniferous base, 
2—5 inches high : leaves spatulate-oblong, obtuse, 3—4 lines 
long: eymes open and few-flowered, the flowers a half inch 
broad; sepals oblong-lanceolate, herbaceous, equal; petals 
not punctate; stamens about 12 in 3 fascicles; styles 3 
elongated ; capsule short and roundish, barely equaling the 
sepals. 
Plant recalling at once the Californian H. anagalloides and 
the Mexican H. pauciflorum, but very different from either. 
Ranuncvtus Forrert. Perennial from a fascicle of fleshy- 
fibrous roots, the whole plant canescent with an appressed 
silky-tomentose pubescence: leaves mostly radical, linear- 
oblong, 2—3 inches long, less than an inch broad, on petioles 
of an inch or more, conspicuously 3-veined, the margins entire, 
the apex formed of a large terminal and two smaller lateral 
teeth or lobes: stem erect, almost leafless, 3—7-flowered : 
calyx deciduous: petals 10, oblong with a nearly truncate 
apex, pale yellow: akenes orbicular, compressed, 4 line wide, 
wrinkled along the sharp margin, tipped with a filiform 
straight style. 
VALERIANA RHOMBOIDEA. Stem solitary, from a small oval 
tuber, erect, simple up to the dichotomous inflorescence, about 
a foot high, sparingly puberulent at the nodes, the plant 
otherwise glabrous: leaves an inch long, in about four pairs, 
the lowest obovate, attenuate to a petiole of nearly their own 
length, the upper rhomboid and sessile, all coarsely sinuate-
