trunk, forming very dense, hemispheric masses 8 to 10 cm in 

 diameter. Receptacles obovoid, often more or less compressed- 

 angular by pressure of contiguous ones, 10 to 12 mm in diameter, 

 green, glabrous or nearly so, the umbilicus about 3 mm in 

 diameter; peduncles slender, 1.5 to 2 cm long, with three small 

 bracteoles at the apex. Fertile female flowers numerous, their 

 pedicels up to 1.5 mm in length; perianth short, sheathing the 

 pedicel below, truncate, about 1 mm long. Ovary ovoid, 1.5 

 mm in diameter; style lateral.

 Ramon, Merrill 8089, November 28, 1911, in forests, altitude about 800 m. 



A species manifestly closely allied to Fieus rubrovenia Merr., and very 

 similar to that species, differing in its somewhat appressed-hirsute, not 

 glabrous, branchlets, and its very coarsely lobed-toothed, not merely undu- 

 late leaves.

Frutex circiter 4 m altus ramulis minute puberulis exceptis 

 glaber; foliis alternis, lanceolatis vel anguste lanceolatis, leviter 

 falcatis, usque ad 25 cm longis, utrinque angustatis, apice longe 

 tenuiter caudato-acuminatis, basi acutis, integris, subcoriaceis, 

 laevis, subtus albido-punctatis, nervis utrinque circiter 20 ; recep- 

 taculis axillaribus, solitariis, obovoideis, 1 ad 1.5 cm diametro, 

 pedunculatis, bracteis circiter 2 mm longis. 



An erect, nearly glabrous shrub about 4 m high. Branches 

 terete, slender, reddish-brown, glabrous, the younger branchlets 

 somewhat puberulent. Leaves alternate, subcoriaceous, lanceo- 

 late to narrowly lanceolate, 12 to 25 cm long, 1.5 to 3 cm wide, 

 somewhat falcate, narrowed at both ends, the apex very slenderly 

 caudate-acuminate, the acumen up to 4 cm in length, minutely 

 apiculate, the base equilateral, usually acute, rarely slightly 

 obtuse, minutely cucullate on the upper surface, the margins 

 quite entire, somewhat revolute, the upper surface smooth, gla- 

 brous, shining, rather pale or somewhat olivaceous when dry, 

 the lower surface somewhat paler, or brownish, distinctly white- 

 puncticulate under a lens; lateral nerves about 20 on each side 

 of the midrib, rather distinct, anastomosing, the ultimate retic- 

 ulations distinct, angular, about 1 mm in diameter; petioles 5 

 to 10 mm long; membranaceous, deciduous, linear-lanceolate or 

 narrowly lanceolate, acuminate, 1.5 to 2 cm long. Receptacles 

 axillary, solitary, obovoid, 1 to 1.5 cm in diameter, glabrous, 

 somewhat narrowed at the base into a very short pseudo-stalk, 

 their peduncles slender, 5 to 10 mm long, with three, ovate, 

 obtuse, 2 mm long bracts at the summit. Gall flowers very num- 

 erous, in general obovoid, sessile or shortly pedicelled, about 2.5
