HEDYOTIS Linnaeus 
HEDYOTiS CAUDATA sp. nov. 
Frutex erectus (vel scandens?) glaber, ramulis obtuse angu- 
latis; foliis chartaceis, nitidis, ovatis vel oblongo-ovatis, usque 
ad 12 cm longis, petiolatis, apice caudato-acuminatis, nervis 
utrinque 7 vel 8, baud prominentibus ; stipulis brevibus, lacin- 
iatis; inflorescentiis paniculatis, laxis; floribus circiter 5 mm 
longis, bracteolis ciliatis. 
An erect or scandent glabrous shrub, the branchlets slender, 
green, somewhat quadrangular, the angles rounded, the inter- 
nodes 6 to 10 cm long. Leaves ovate to oblong-ovate, charta- 
ceous, somewhat shining, rather pale, and of about the same 
color on both surfaces when dry, 6 to 12 cm long, 3 to 4 cm 
wide, base acute, apex rather slenderly caudate-acuminate ; nerves 
7 or 8 on each side of the midrib, not prominent, the reticula- 
tions obscure; petioles 5 to 10 mm long; stipules 4 to 5 mm 
long, laciniately 3- to 5-toothed, the teeth narrow, prominently 
pubescent. Inflorescence paniculate, terminal and in the upper- 
most axils, sessile and branched from the base, or peduncled, lax, 
the branches usually 4 at each node, spreading, the branchlets 
also arranged in threes or fours. Flowers white, their pedicels 
3 to 5 mm long, subtended by oblong to oblong-ovate, prominently 
ciliate, 1 to 1.5 mm long bracteoles, the bracts of the ultimate 
branchlets linear, 3 to 4 mm long, ciliate, those of the primary 
branches similar but twice as long and glabrous. Corolla-tube 
about 2 mm long, glabrous on both surfaces, the lobes 4, oblong, 
obtuse, 2.5 mm long. Calyx glabrous, somewhat urceolate, about 
2.5 mm long, 4-lobed, the lobes oblong, acuminate, about 1.5 mm 
long. Filaments slender, exserted; anthers narrowly oblong, 
1.2 mm long. Fruit unknown. 
Luzon, without definite locality, Loher 6il9. 
A species perhaps most closely allied to Hedyotis scandens Roxb., which 
extends from India and Burma to southern China, but with differently 
shaped leaves, quite different stipules, more lax inflorescence, and the 
corolla quite glabrous, not bearded within. 
HEDYOTIS HUMILIS sp. nov. 
Suffruticosa, erecta, glabra, 30 ad 60 cm alta, hand ramosa, 
caulibus teretibus, circiter 3 mm diametro, partibus junioribus 
distincte 4-angulatis ; foliis lanceolatis, 4 ad 5 cm longis, acumin- 
atis, utrinque subaequaliter angustatis, nervis lateralibus sub- 
obsoletis ; inflorescentiis axillaribus, longe graciliter pedunculatis, 
paucifloris, 7 ad 12 cm longis; corolla 6 mm ionga, intus villosa.
