Hedyotis congesta Iv. lir. in \\'all. Cat. No. 844. 

 In an old ek-arin-i' at TOO m. alt. (No. rtrilM). 

 Widely distributed in the Pliilippines. 

 Malayan i)eninsula and arcliipelago.

 capitato-congestis, bracteis foliaceis plus miniisve involucratis. 



Suffrutescent or woody, erect, much branched, 0.(5 to 1.4 m. high. 

 I)ranches slender or somewliat thickened, brown, pubescent, becoming 

 ghibrous. Leaves membranous, ol^long-ovate to ovate-lanceolate, 3 to 

 7 cm. long, 1 to 2.5 cm. wide, the apex acute or sharp-acuminate, the 

 l)ase 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 lacinifB 

 setiform, ])ubescent, 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 nun. long, the mature capsule 2 to 

 2.5 mm. long. 



In forests at 1,800 ni. alt. (No. 5726); also collected by Mcrritt at 1,000 ni. 

 alt. (Nos. 4417, 4430). 



A species evidently closely related to Hedyotis macrostegia Stapf, from Mount 

 Kinabalu, North Borneo, difllering 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.() m. altus, ramis ramulisque crassiuseulis tetragonis, 

 glabris, foliis rigide coriaceis, ovatis, acutis, glabris, nitidis, 1.5 ad 3 cm. 

 longis, basi late rotundatis ant su1)truncatis; inflorescentiae axillares, 

 pauciflorae, cymosae; corolla alba, G 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, f(3w 

 flowered, cymosc, the })eduncles 1.5 cm. long or less, the branches few.
