Hedyotis congesta R. Br. in Wall. Cat. No. 844. 
In an old clearing at 700 m. alt. (No. 5531). 
Widely distributed in the Philippines. 
Malayan peninsula and archipelago. 
Hedyotis eucapitata Merrill n. sp. 
Frutex vel sufl'rutex 0.6 ad 1.4 m. altus, ramis ramulisque gracilibus 
aut crassiusculis, puberulis, foliis oblongo-ovatis vel lanceolato-ovatis, 
acutis vel acuminatis, 3 ad 7 cm. longis, pubescentibus, nervis 3 ad 5 
utrinque, stipulis liberis, 4 ad 5 mm. longis/ fimbriatis, pubescentibus; 
inflorescentiae axillares, pedunculo 2 ad 4 cm. longo, puberulo; floribus 
capitato-congestis, bracteis foliaceis plus minusve involucratis. 
Suffrutescent or woody, erect, much branched, 0.6 to 1.4 m. high. 
Branches slender or somewhat thickened, brown, pubescent, becoming- 
glabrous. Leaves membranous, oblong-ovate to ovate-lanceolate, 3 to 
7 cm. long, 1 to 2.5 cm. wide, the apex acute or sharp-acuminate, the 
base acute, both surfaces pubescent with weak scattered hairs, dull; 
nerves 3 to 5 on each side of the midrib, ascending, distinct; petioles 
pubescent, 0.5 to 1.5 cm. long; stipules pubescent, laciniate, the laciniae 
setiform, pubescent, 4 to 7 mm. long. Inflorescence axillary, the pedun- 
cles pubescent, 2 to 4 cm. long, slender, each bearing.a single terminal 
head of sessile flowers, 1 cm. in diameter or less, the bracts foliaceous, 
forming an involucre, the bracts and flowers more or less hispid-pubescent, 
the pedicels 1 mm. long or less. Calyx tube about 1 mm. long, the lobes 
4, linear or linear-lanceolate, 2.5 mm. long, the mature capsule 2 to 
2.5 mm. long. 
In forests at 1,800 m. alt. (No. 5726) ; also collected by Merritt at 1,600 m. 
alt. (Nos. 4417, 4430). 
A species evidently closely related to Hedyotis maerostegia Stapf, from Mount 
Kinabalu, North Borneo, differing from that species in its pubescent, fewer nerved 
leaves, much shorter stipules, and other characters. It is distinguished from all 
other Philippine species of the genus by its long peduncled capitate solitary 
axillary inflorescence. 
Hedyotis whiteheadii Merrill n. sp. 
Frutex 2 ad 2.6 m. altus, ramis ramulisque crassiusculis tetragonis, 
glabris, foliis rigide coriaceis, ovatis, acutis, glabris, nitidis, 1.5 ad 3 cm. 
longis, basi late rotundatis aut subtruncatis ; inflorescentiae axillares, 
pauciflorae, cymosae; corolla alba, 6 mm. longa. 
An erect branched shrub glabrous throughout, 2 to 2.6 m. high. 
Branches stout, tetragonous, green or brown, smooth. Leaves ovate, 
usually broadly so, 1.5 to 3 cm. long, 1 to 1.8 cm. wide, the base broad, 
rounded or subtruncate, gradually narrowed above to the acute apex, 
rigid coriaceous, shining, the margins often recurved; nerves 3 to 4 on 
each side of the midrib, not prominent; petioles stout, 2 mm. long or 
less; stipules 3 to 4 mm. long, usually trifid. Inflorescence axillary, few 
flowered, cymose, the peduncles 1.5 cm. long or less, the branches few.
