younger branchlets pubescent, otherwise glabrous. Heads about 
1.5 cm long, each peduncle with several, scattered, filiform bracts 
usually about 5 mm in length. Bracteoles about 10, linear- 
lanceolate, acuminate, about 12 mm long, glabrous. Achenes 
glabrous. 
Luzon, Abra Province, Mount Posuey, Bur. Sci. 27023 Ramos, February 
4, 1917, climbing over shrubs on damp forested slopes. 
In many respects this species resembles Gynura bicolor DC. and G. 
angulosa DC., but differs from both in being scandent, not erect, and from 
the former in its sessile, not petioled leaves. • 
GYNURA ACUMINATISSIMA sp. nov. 
Erecta, glabra, usque ad 50 cm alta; foliis lanceolatis, mem- 
branaceis, longissime acuminatis, basi decurrento-acuminatis, 
usque ad 20 cm longis et 4 cm latis, margine distanter irregulari- 
ter dentatis vel denticulatis, nitidis; inflorescentiis laxis, corym- 
bosis, ramis elongatis; capitulis circiter 1.5 cm longis, bracteo- 
latis, bracteis lineari-lanceolatis, circiter 12 mm longis. 
An erect glabrous or nearly glabrous plant, attaining a height 
of 50 cm, the stems below attaining a diameter of 5 mm, terete, ' 
brown. Leaves somewhat crowded on the lower part of the 
stem, lanceolate, membranaceous, brownish when dry, shining, 
17 to 20 cm long, 3 to 4 cm wide, gradually narrowed upward 
to the long and slenderly acuminate apex, the base decurrent- 
acuminate, the margins distantly and irregularly toothed, or 
sometimes merely denticulate, the smaller reduced leaves sub- 
tending the branches sessile, often laciniate-lobed in the lower 
part, the petioles of the normal leaves 2 to 4 cm long. Inflores- 
cence corymbose, lax, the branches slender, elongated, up to 20 cm 
long, each primary branch bearing two or three heads on long, 
slender, slightly pubescent branchlets. Heads about 1.5 cm long, 
each subtended by about 10, linear, glabrous, 6 mm long brac- 
teoles. Involucral bracts linear-lanceolate, glabrous, about 3 mm 
wide and 12 mm long, glabrous. Flowers numerous, yellow. 
Corolla-tube slender, about 12 mm long, the upper 2 mm of the 
tube somewhat inflated, the lobes 2 mm long, slightly pubescent 
at their tips. Achenes cylindric, ribbed, 3 mm long. Pappus 
copious, white, 8 to 10 mm long. Disk conspicuously alveolate, 
the margins of the alveolae produced, scale-like, about 0.5 mm 
long. 
Luzon, Tayabas Province, Mount Dingalan, Bur. Sci. 26556 Ramos & 
Edano, August 26, 1916, on slopes at medium altitudes. 
A most characteristic species, readily distinguished from its congeners in 
its glabrous, lanceolate, very slenderly acuminate leaves.
