RANUNCULUS Linn. 
Ranunculus philippinensis Merrill & Rolfe sp. nov. 
Caespitosus, plus minus liirsutus^ usque ad 15 cm altus; foliis tripar- 
titis, 1.5 ad 2 cm longis, segmentis trifidis, acutis; fioribn? torminalibus, 
solitariis, luteis, 1.5 cm diam., petalis oblougo-obovatis, obtusis; acheniis 
6 ad 15, compressiusculis, in capitnia globosa aggregatis, glabris, punc- 
tatis ; stylo uncinato persistente. 
A tufted, acaulescent species with erect l-flowered scapes, but under 
some conditions stoloniferous. Petioles 3 to 15 cm long, erect, with 
scattered appressed hairs which are more numerous below. Leaves tri- 
foliolate, 1.5 to 2 cm long ^\■iai scattered appressed or .spreading long 
white hairs on both surfaces, the leaf-segments 1.5 cm long or less, the 
middle one longer petioluled tlian the lateral' ones, each segment cut 
into three, rarely more, ovate, acute lobes, the sinus very narroAV, acute. 
Pedicels erect, somewhat appresscd-hirsute, 4 to 15 cm long, l-flowered. 
Flowers yellow, 1.5 cm in diameter. Sepals membranous, oblong-ovate, 
with few long hairs outside, about 5 mm long. Petals 5, oblong-obovate, 
apex rounded, narrowed at the base, ubouL 8 nmi long, 4 mm wide. 
Filaments nearly 3 mm long; anthers 1.5 mm long. Achenes 6 to 15 
in globose lieads, compressed, glabrous, punctate, 3.5 mm long, 2 mm 
wide, terminated by a somewliat curved beak about 1 mm long.

In mossy forests and in swamps above 2,250 ni alt., the genus new to the 
Philippines. 
A most interesting species, which strangely enougli <ioes not have its closest 
allies to the north and west, but in the southeast in Queenslaii<l nnd New Zealand. 
It is in fact so closely allied to the Australian Ranunculus hqqxirrus Sm., that 
it is difliuult to distinguish the Philippine plant from some forms of the Australian 
species. Howe\;er, Ranunculus philippinensis is smaller than typical R. lappa- 
ceus. is much more hirsute than the latter, and has nuuTi fi'\ver achenes. minor
