Hedyotis.] LXXV. RUBIACE&. (J. D. Hooker.) 49 
Coore, Beddome; CeyLon, near Colombo, W. Ferguson. 
Branches 1-2 ft. Leaves 1-14 in., and whole plant pale green when dry. Corolla 
4 in. long.—A very singular plant, which I was at first disposed to consider as 
belonging to Psychotriez, but which I think now to be closely allied to Alleophania, 
as I suspected when placing it in that tribe in the “Genera Plantarum.” It differs 
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 
Alleophania. 
20. HEDYOTIS, Z. 
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.—DiIsTRIB. 
Species about 80, chiefly tropical Asiatic. 
A very difficult genus to define, a few species being intermediate between it, 
Anotis and Oldenlandia. 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. 
Secr. I. Diplophragma. 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, cymes terminal or axillary, rarely corymbose or panicled, 
very rarely capitate ; stipules not large and sheathing. 
+ Stipules entire or gland-serrate or -crenate, rarely pectinate. 
l. H. 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- 
otidea, DC. Prodr. iv. 555.—Rheede Hort. Mal. iv. t. 57. 
AYANCORE Mts., Rottler, $c. Cryton, common up 3000 ft. 
AR 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 coneavo-convex.— Wight 
and Arnott's var. B., with hispid cymes, appears to be H. pruinosa; Wallich's 837 b, 
the same authors refer to this species because it was gathered by Rottler, but 
Rottler's Herbarium contains Malayan plants, and that in question is H. capitellata, 
Ke a 837 a, also from Rottler's Herbarium, is H. pruinosa. 
` H. Maingayi, Hook. f.; glabrous, leaves shortly petioled lanceolate 
or te-lanceolate acuminate nerveless, stipules entire eglandular, cymes ter- 
ming panicled, calyx-teeth lanceolate longer than the capsules. 
ALACCA; on Mt. Ophir, Griffith, Maingay (Kew Distrib. 887). 
A shori 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 
lanepolate.
