194 PITTONIA. 
glabrous toward the base, short-jointed and moniliform, the 
joints 6 or 7, scarcely turgid, rounded and delicately rugu- 
lose-striate: stigmas short, subulate-linear, notably hirtellous. 
Apparently endemic on Santa Catalina Island, whence it 
has been distributed to several herbaria by Mrs. Trask. 
52. P. serosus. Compactly branched and depressed, 
single plants 5 to 8 inches broad, hardly as high, very 
leafy; branches not slender, glabrous, glaucous: leaves 
linear-oblong, 1 inch long or more, obtuse, appearing as if 
remotely serrate by the enlarged bases of a few short stiff 
marginal hairs, the upper face with similar scattered setose 
hairs: peduncles short, stoutish, setose-hispid, nodding in 
fruit: corolla 4 inch broad, cream-color, rotate, the outer 
petals obovate-oblong, the inner elliptical, all thin, venu- 
ose: filaments narrowly linear, rather hyaline than 
petaloid, narrower at the obtuse at summit than the long 
linear anthers: fruits oval, hardly 4 inch long, the 10 or 
12 carpels moniliform, the 5 or 6 short joints marked with 
delicate nerves and a low rather obscure intervening tuber- 
culation ; stigmas filiform, radiating.

THREE NEw RANUNCULI. 
R. CARICETORUM. Stout perennial, at early flowering 
almost upright and often 2 feet high ; later reclining, root- 
ing at the upper nodes; commonly very hirsute, at least as 
to petioles and lower part of stem, otherwise sparingly hir- 
sute-pubescent: lowest leaves long-petioled, either com- 
pletely biternate or the 3 leaflets deeply cleft into 3 cuneate- 
obovate incised lobes, the whole leaf of a somewhat deltoid 
outline, the largest 5 or 6 inches long and quite as broad : 
flowers few, large, the corolla more than an inch broad, the
