HAB. Mt. Morrison. 



OBSERV. Apparently perennial with long fibrous roots. Stein slender, 

 hirsute, branchless, with a solitary Mower. Radical leaves long petiolate, 

 petioles 6 cm. long, slender, nearly glabrous or thinly hairy, blades rounded 

 in outline, 3-5-lobed towards the apex, somewhat thick, nearly glabrous 

 or hirsute. Cauline leaves 1 at the middle portion of the stem, subsessile, 

 deeply 3-lobed, lobes lanceolate, obtuse or acute, hirsute. No flowers, in- 

 determinable. There is something like this at Kew, labelled Ranunculus 

 philipplnensia MERE et ROLFE. Without examining the flowers, it is difficult 

 to say whether our plant is identical with the Philippine plant or not.
