 or lanceolate; nerves close; stipules connate into a scarious bristly tube. 

 FUmers minute, polygamo-dioecious, in axillary dense cymes, pale purple. 

 Calyx-tvhe obconic ; limb bell-shaped, 4rribbed and ■with 4 bristle-like teeth,

 bud. Stamens 4, inserted between the coroUar-lobes, filaments of ^ long ex- 

 serted ; anthers Unear-oblong, obtuse. Ovary 4-celled ; style filiform, $ ex- 

 serted, arms 4 linear; ovules 1 basilar erect in each cell. D-uit small, tm-- 

 binate, with 4 bony indehiscent pyrenes. Seeds erect, minute, broadly oblong or

 short, cylindric. — Distbib. Species 3, one Malayan, the others as below. 



1. A. deciplens, Thw. JEnum. 147; more or less hirsute or glabrate,. 

 leaves sessUe or petioled ovate or lanceolate acute or acuminate, nerves strong 

 beneath, stipules bi'oad, calyx-teeth equalling the hairy fruit. Hedyotis nodu— 

 losa, var. a. Thw. Enum. 143, as to C. P. 105, not of Arnott. 



Cetxon ; Central Province, alt. 3-7000 ft. 



An erect 3-chotomously branched shrub. Leaves 1-2 J by ^1 J in., usually coria- 

 ceous and hairy or scabrid above, very variable in shape from broad ovate to narrow- 

 lanceolate, base acuminate rounded or cordate, upper surface flat or bullate ; petiole- 

 or ^-5 in. ; stipular bristles hairy. Calyx-limb membraaous. Corolla-tvhe hairy, 

 lobes narrow, villoais within. Style slender, hairy, arms spreading. — There are three 

 varieties : one with broad sessile or petioled coriaceous leaves, scabrid above, with 

 very strong nerves beneath ; the second (var. flavescens, Thw. 1. c.) with ovate-cordate 

 petioled membranous very hairy leaves ; the third with narrow-lanceolate coriaceous 

 leaves glabrous and wrinkled above and strong hairy nerves beneath. — Closely allied 

 to Hedyotis rugulosa, Korth., of the Malayan Islands, which has much longer calyx- 

 teeth, on which Miquel founded the section Tetragyneia of Hedyotis. 



2. A . Amottii, Hook. f. ; glabrous or nearly so, leaves petioled ovate-' 

 lanceolate acuminate nerves distinct, stipules caducous ovate with few sub- 

 tei"minal bristles, calyx-teeth shorter than the glabrous fruit. — Hedyotis nodu- 

 losa, var. a. Thwaites Enum. 143, as to C. P. 87, not of Arnott. 



CbyI/ON ; Newera Ellia, Gardner ; Adam's Peak, Thwaites. 



Closely allied to A. decipiens, but almost glabrous, with longer differently shaped 

 stipules, smaller glabrous fruit and shorter calyx-teeth; the style, too, is quite- 

 glabrous. 



19. FEBG'USOM'XA, Sook.f. 



A slender procumbent herb, branching from the base ; branches very long, 

 rooting below, acutely 4rangled; nodes cUiate. Leaves opposite, subsessile, 

 lanceolate, scaberulous, 1-nerved, margin recurved ; stipules connate with th& 

 petioles, erect, herbaceous, lanceolate, ciliate, persistent. Flowers small, axil- 

 lary, shortly pedicelled, 2-bracteolate. Calyx-tube subpyriform ; lobes 4, erect, 

 lanceolate, ciliate, persistent. Corolla funnel-shaped, thxoat glabrous or hairy ; 

 lobes 4, short, vEilvate in bud, tips ciliate. Stamens 4, inserted between the 

 coroUa-lobes, filaments short ; anthers linear-oblong. Dish epigynous, 4-lobed. 

 Ovary 4rcelled; style filiform, arms 2 linear hairy; ovules 1 basilar erect in 

 each cell. Fruit of 4 pear-shaped coriaceous cocci crowned with the calyx- 

 teeth. Seeds erect, pyriform ; embryo compressed, subeylindric, radicle inferior.
