Luzon, Province of Rizal, Novaliches, Loher 6, May 25, 1890. 
A most characteristic species, at once recognizable by its solitary long- 
pedicelled flowers and tailless achenes.

Himalayan region to central and southern China and Formosa; an interesting 
example of the eastern extension of the Himalayan flora to the high table-land 
of northern Luzon. 
RANUNCULUS Linn. 
Ranunculus phil ippinensis Merrill & Rolfe sp. nov. 
Caespitosus, plus minus hirsutus, usque ad 15 cm altus; foliis tripar- 
titis, 1.5 ad 2 cm longis, segmentis trifidis, acutis; floribus terminalibus, 
solitariis, luteis, 1.5 cm diam., petalis oblongo-obovatis, obtusis; acheniis 
6 ad 15, compressiusculis, in capitula globosa aggregatis, glabris, punc- 
tatis ; stylo uncinato persistente. 
A tufted, aeaulescent species with erect 1-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 with scattered appressed or spreading long 
white hairs on both surfaces, the leaf -segments 1.5 cm long or less, the 
middle one longer petioluled than the lateral ones, each segment cut 
into three, rarely more, ovate, acute lobes, the sinus very narrow, acute. 
Pedicels erect, somewhat appressed-liirsute, 4 to 15 cm long, 1-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, about 8 mm long, 4 mm wide. 
Filaments nearly 3 mm long; anthers 1.5 mm long. Achenes 6 to 15 
in globose heads, compressed, glabrous, punctate, 3.5 mm long, 2 mm 
wide, terminated by a somewhat curved beak about 1 mm long.

1905; Loher 11, February, 1894. 
In mossy forests and in swamps above 2,250 m alt., the genus new to the 
Philippines. 
A most interesting species, which strangely enough does not have its closest 
allies to the north and west, but in the southeast in Queensland and New Zealand. 
It is in fact so closely allied to the Australian Ranunculus lappaceus Sm, that 
it is difficult to distinguish the Philippine plant from some forms of the Australian 
species. However, Ranunculus philippinensis is smaller than typical R. lappa- 
ceus, is much more hirsute than the latter, and has much fewer achenes, minor
