2. ARTHROPHYLLUM JUuiiie. 
1. Arthrophyllum ahernianum Merrill, sp. nov. 
A tree about 12 iii. high, with very long pinnate leaves, the leallets ohioug 
to oblong lanceolate, short aciuninate, glabrous. Leaves up to 1 in. in length, 
the upper ones much smaller, the lower ones with 30 or more leallets, the up]ier 
ones with 5 or (i leaflets, the I’hachis jointed, glabrous; leallets 10 to 18 cm. 
long, 2.5 to 5 cm. wide, membranous, [)ale when dry, entire, the base rather 
abruptly acute, usually strongly iiUMpiilateral, the a]>ex short acuminate, the 
acumen hhuit or sharp; primary nerves about (i on each side of the midrib, 
arched ascending, somewhat prominent, the secondary nerves and reticulations 
distinct beneath, lax; petiohdes 5 to 10 mm. long. Umbels sid)tended by 3 or 
4 elliptical ovate leaves nearly as long as the umhellules, each umbel consisting 
of 8 to 10 umhellules, glabrous or deeiduously ferruginous j)uhescent; undjellules 
10 to 15 flowered, the peduncles 4 to 5 cm. long, the jiedicels 1 cm. long or less. 
Calyx about 3 mm. long, truncate. Petals 5, oblong ovate, acute, 4 mm. long, 
about 2 mm. wide, free. Stamens 5; filaments 5 mm. long; anthers curved, 
about 2 mm. long. Ovary 1 -celled, 1-ovuled; style 0. Fruit uid-;nown. 
(2780 Meyer) February; {Whitfonl). In dense forests on steej) slopes at 
about (iOO m., difi'ering from ArthropJtylhnii i)iiin<tfiim Clarke, to which it is 
apparently related, in its much longer leaves and larger more numerous leallets 
which are not caudate acuminate.

2. Schefflera acuminatissima Merrill, sp. nov. 
Scandent on trees, reaching a height of 15 m. Branches giay or brownish, 
glabrous, striate, the ultimate hranchlets often with few scattered stellate hairs, 
d^eaves digitately 7 to 10 foliolate, alternate, the common ])etiole glabrous. 11 to 
17 cm. long; leaflets narrowly oldong lanceolate or ohlanceolate, glabrous sub- 
membranous, slightly shining above, the apex jirominently slender caudate 
acuminate, often abruptly so, the base acute or slightly rounded, the margins 
entire, 8 to 15 cm. long, 2 to 4 cm. wide, for most |)art rvidest in the \ti>per 
portion; primary nerves 15 or more on each side of the midrib, scarcely more 
prominent tlian the secondary nerves and reticulations, anastomosing; petioles 
slender, glabrous, 2 to 3.5 cm. long. Panicles terminal, each with 4 or 5 ascend- 
ing branches 15 cm. long or less, the rhachis and branches more or less covered 
with weak, pale, somewhat stellately disposed hairs, tin* primary branches bear- 
ing numerous racemosely disposed slender, usually spreading 1 cm. long Itranch- 
lets, each siditended by a deciduous, membranous, ovate or ovate lanceolate, 
acuminate bract about 1 cm. long, the flowers umbellately disjiosed at the tips 
of the hranchlets, about 10 flowers in each umbel, their peilieels 1.5 to 2 mm. 
long. Calyx funnel shaped, truncate, 2 mm. long. Petals 5. greenish, narrowly 
ovate, acute, glabrous, 2 mm. long, 1.2 mm. wide, slightly united at their tips, 
separating from the base and falling as a whole. Stamens 5; filaments slender, 
5 mm. long; anthei's 1 mm. in diamener. Ovary 5-celled. Fhaiit yellow, ovoid 
to elliptical ovoid, 4 to 5 mm. long, 5-celled, 5-ridged, truncate, crowned by the 
flattened styles.
