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 philippinensis Merrill & Rolfe sp. nov. 



Caespitosiis, plus minus hirsutus, usque ad 15 cm altus; foliis tripar- 

 titis, 1.5 ad 3 cm longis, segmentis trifidis, acutis; floribus terminalibus, 

 solitariis, luteis, 1.5 cm diam., petalis ol)longo-obovatis, obtusis; acheniis 

 6 ad 15, compressiusculis, in capitula globosa aggregatis, giabris, punc- 

 tatis ; stylo uncinate persistente. 



A tufted, acaulescent species with erect 1-flowered scapes, but under 

 some conditions stoloniferous. Petioles 3 to 15 cm long, erect, with 

 scattered appressed Jiairs 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-hirsute, 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 G to 15 

 in globose heads, compressed, glal)rous, punctate, 3.5 mm long, 2 mm 

 wide, terminated by a somewhat curved beak about 1 mm long.

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.. tliat 

 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
