1332 LEAFLETS or PHILIPPINE BOTANY [Vor. IV, Arr. 70 
slender ultimate ones with glabrate and suberect tips. Leaves 
submembranous, opposite, 1 to 3 pairs at the ends of the branch- 
lets, horizontal, the abrupt sharply acuminate tips recurved, 
much paler green beneath, glabrous, drying green though unequal- 
ly so on the 2 sides, obovately oblong or broadly oblanceolate, | 
entire, base slenderly cuneate, blades 17.5 em. long by 6 cm. E 
wide above the middle; midvein whitish in the fresh state, eon- | 
spieuously raised beneath, grooved on the upper side; lateral 
nerves 14 to 19 pairs, parallel, oblique, tips curved and gradually 
disappearing, also prominent, glabrous, eross bars very faint; 
petiole 1 cm. long or longer, pulverulent especially along the 
lower side; stipule brown, thin, caducous, at least 1 cm. long, 
oblong, grayish hairy on the inner side toward the base, otherwise 
glabrous, obtusely pointed. Flowers usually solitary, terminal, ‘ 
suberect, subtended by bracts, subsessile; calyx pale or light | 
green, 4.5 cm. long, glabrous, the basal 1 em. subcompressed and 
somewhat tapering toward the base, the middle portion strongly j 
carinate or winged and extended into the 5 segments; segments P 
green, finely nerved, linearly oblong, 4 mm. wide, 2 cm. long, 
subfalcate and acute toward the apex, occasionally with blunt 
dwarfed intermixed appendages or lobes; corolla tube creamy 
white, 6 cm. long, 6 mm. thick, subglabrate; lobes in the bud 
strongly imbricated and twisted from right to left, similar in 
color but soon turning deeper yellow, averaging 9, much narrowed 
and unequal at the base, oblong, 5 cm. long by 1.5 cm. wide across 
the middle, deflexed; stamens as many as there are corolla seg- 
ments, inserted upon the glabrous throat, linear, 1.5 cm. long, 
obtuse at apex, striate and more or less twisted, upon short and 
glabrous filaments, alternating with the segments; style 1.25 
mm. thick, terete, glabrous especially the basal portion; ovary

It differs particularly from G. barnesii Merr. in the calyx 
and from G. pseudosidium Blco. in the corolla segments. There 
are other minor differences.
