more numerous similar ones subtending the involucre. Involucral bracts 
about 12, linear, about 13 mm long, 2 to 2.5 mm wide, glabrous, or 
very slightly pubescent at the tips, margins hyaline, apex acute or 
acuminate. Flowers orange-yellow, about 60 in each head. Achenes 
glabrous, nearly 2.5 mm long. Corolla slender, tubular, 1.5 cm long, 
narrowly-campanulate at the apex, and with 5 oblong, 1.5 mm long 
lobes. Anthers 2.3 mm long. Style-arms spreading or recurved, 3.5 
mm long. Pappus white, copious, nearly as long as the corolla-tube. 
Disk shortly fimbrillate.

Among the Philippine species, this proposed new one is. most closely allied to 
Gynura vidaliana Elmer, but is at once distinguished from that' species by being 
almost entirely glabrous, as well as by its sessile, reduced, and usually cordate 
upper leaves. In many respects it similates Gynura sarmentosa DC., but is at 
once distinguished from that species by its erect habit, larger heads, and larger 
leaves. It is manifestly allied to the extra-Philippine group represented by 
Gynura nitida DC., G. angulosa DC., G. pseudo-china DC., and G. bicolor DC., but, 
so far as I can determine from the descriptions, is apparently distinct from all. 
SENECIO Linn. 
1. S. confusus Elmer Lead. Philip. Bot. 1 (1906) 153. 
In the pine region, extending into the lower parts of the mossy forest, G. M. Z. 
16115, Merrill 6589. 
Confined to the higher altitudes of the Benguet-Lepanto region. 
This species is apparently the Philippine representative of Senecio scandens 
Ham., which extends from northern India to Ceylon and south-eastern China, and 
may at a later date have -to be reduced to that species. 
2. S. luzoniensis Merr. in Philip. Journ. Sci. 1 (1906) Suppl. 245. 
Bather common in the mossy forest, extending down ravines into the upper 
limits of the pine region, G. M. Z. 16111, Merrill 6567. 
A species known only from high altitudes of the Benguet-Lepanto region, and 
the mountains of Zambales. 
As the preceding species is apparently the Philippine representative of Senecio 
scandens, so the present one apparently is our representative of the widespread 
Senecio nemorensis Linn., which extends from central and northern Europe to 
Eamtschatka, Japan, and China.
