remarkably from the other Hedyotidean genera in the form and insertion of the seed, 

 and in the dimerous style with a 4-merous ovary, but is united with them through 

 Allteophania. 



20. KEDVOTXS, L. 



Herbs, undershrubs or shrubs. Leaves very rarely ternately whorled; 

 stipules free or combined in a bristly sheath. Flowers white or lilac, in ter- 

 minal or axillary open close or capitate cymes. Calyx-lobes 4, acute, persistent, 

 without interposed teeth. Corolla funnel- or bell-shaped; lobes 4, ovate, or 

 linear, valvate in bud. Stamens 4, in the tube or throat of the corolla. Ovary 

 2-celled : style filiform, stigma 2-fid or 2-lobed ; ovules numerous on sessile or 

 pedicelled placentas, attached to the septum at or below the middle. Fruit 

 small, membranous coriaceous or crustaceous, indehiscent or septi- or loculi- 

 cidal or of 2 separable or connate cocci, 2-many-seeded. Seeds plano-convex or 

 angled, testa very rarely winged ; embryo clavate in horny albumen. DISTRIB. 

 Species about 80, chiefly tropical Asiatic. 



A very difficult genus to define, a few species being intermediate between it, 

 Anotis and Oldenlandla. Flowers rarely 5-merous. The solitary ovules on the face 

 of the septum in each cell, and the seeds, distinguish Spermacoce from it ; in habit 

 they are often very similar. 



SECT. I. Diploph rag-ma. Capsule septicidally splitting into two 1-4- 

 (rarely more-) seeded cocci, which dehisce ventrally, top not protruded between 

 the calyx-teeth. Erect or decumbent shrubs or herbs ; stipules various. /- 



* Erect shrubs j cymes terminal or axillary, rarely corymbose or panicled, 

 very rarely capitate ; stipules not large and sheathing. 



t Stipules entire or gland-serrate or -crenate, rarely pectinate. 



1. ZZ. fruticosa, Linn. ; glabrous, branches obtusely 4-angled, leaves 

 petioled lanceolate acuminate, nerves distinct, stipules gland-crenate, cymes 

 terminal panicled, calyx-teeth triangular recurved shorter than the ovoid smooth 

 capsule. W. $ A. Prodr. 408 ; Burm. Fl. Zeyl. t. 107. Spermacoce ? hedy-

TKAVANCORE Mts., Bottler, $c. CEYLON, common up 3000 ft. 



An erect shrub, green when dry. Leaves 2-4 in., coriaceous ; nerves 6-12 pair. 

 Corolla-throat woolly. Seeds 4 in each cell, plano-convex, or concavo-convex. Wight 

 and Arnott's var. &., with hispid cymes, appears to be H. pruinosa; Wallich's 837 , 

 the same authors refer to this species because it was gathered by Rottler, but 

 Bottler's Herbarium contains Malayan plants, and that in question is H. capitellata. 

 Wallich's 83 7 a, also from Bottler's Herbarium, is H. pruinosa. 



2. ZZ. BTaing-ayi, Hook. /. ; glabrous, leaves shortly petioled lanceolate 

 or ovate-lanceolate acuminate nerveless, stipules entire eglandular, cymes ter- 

 minal panicled, calyx-teeth lanceolate longer than the capsules. 



MALACCA ; on Mt. Ophir, Griffith, Maingay (Kew Distrib. 887). 



A short much branched shrub, green when dry, 12-18 in. Leaves 1-2 in , acute 

 or rounded at the base, petiole winged. Flowers more crowded than in H fruticosa ; 

 flowers and fruit and seeds similar, except that the calyx-teeth are much longer and 

 lanceolate.
