MERRILL AND MERRITT. 
apice breviter acuminatis, basi rotundatis vel subeordatis, usque ad 23 
cm longis; floribus 5- vel 6-meris, in capitulis globosis dispositis, ebrac- 
teolatis ; capitulis circiter 1 cm diametro, racemose dispositis. 
A shrub or tree 4 to 15 m high, glabrous, except the very young leaves 
and growing tips of the branches which are densely furfuraceous-pubes- 
cent. Branches light-gray, thickened. Petioles- 30 to 50 cm long; 
stipules very thickly coriaceous, almost woody, about 4 cm long; leaflets 
digitate, 11 or 12, very thickly coriaceous, usually brownish-yellow when 
dry, oblong; 18 to 23 cm long, 5 to 9 cm wide, shining, the apex acu- 
minate, the base rounded or subcordate ; primary nerves about 12, rather 
distinct, anastomosing, the secondary ones often distinct; petiolules 
6 to 11 cm 'long. Flowers in. dense globose heads, ebracteolate, 5- or 
6-merous. Heads 20 to 40 in each raceme, in fruit reddish or purplish, 
about 1 cm in diameter, glabrous, their peduncles 1 to 3 cm long; 
racemes 40 to 50 cm long, glabrous. Fruits in dense globose heads, 
5 to 6 mm long, about 40 in each head, glabrous, narrowly obovoid, 
shortly 5- or 6-angled, the apical portion subcorneal, 5- or 6-sulcate, 
5- or 6-celled; seeds narrowly oblong, flattened, 3.5 to 4 mm long. 
In the mossy forest above 2,250 m, For. Bur. 18126 Curran, Merritt, & 
Zschoklce, January 7, 1909 (type) . I refer to the same species the following 
specimens: Province of Benguet, near Baguio, Loher 3589, For. Bur. 18321 Al- 
varez, Williams 1305, Elmer 8693; Mount Tonglon, For. Bur. lhhQh Darling: 
Province of Bataan, Mount Mariveles, Merrill 381ft. It is known to the Igorots 
of Benguet as colamot. 
This species is allied to Schefflera blancoi Merr., and the last number cited was 
previously referred by me to that species. It is, however, very distinct from 
S. blancoi, differing in its more numerous, larger, more coriaceous leaflets, its 
much longer and glabrous racemes, much more numerous, smaller glabrous heads 
and other characters. Schefflera blancoi has subglobose to ellipsoid heads 2 to 3 
cm long, from 5 to 10 heads in a raceme, the racemes short, paniculately disposed, 
the branches, and especially the heads furfuraceous-pubescent. 
UMBELLIFERiE. 
HYDROCOTYLE Linn. 
1. H. rotund ifolia Roxb. FI. Ind. 2 (1832) 88. 
Lower borders of the mossy forest and in the upper pine region, C. M. Z. 
16036, Merrill 6537. 
Abundant in the Benguet-Lepanto region; mountains of India and Ceylon to 
southern China and Formosa, Malaya, and tropical Africa. 
If the synonymy as given by C. B. Clarke in Hook. f. FI. Brit. Ind. 2 (1879) 
668 is correct, then the oldest valid name for this species is H. nitidula A. Rich. 
Monog. Hydrocot. (1820) no. 35, f. 33. The first use of the specific name 
rotundifolia by Roxburgh (1814), is a nomen nudum. H. rotundifolia Roxb. as 
interpreted by C. B. Clarke includes the two Philippine species recently described 
by Mr. Elmer, H. benguetensis and E. delicata.
