slender, decumbent, ramose, densely matted, with old small leaves ; the upper 

 portion ascending or erect, simple, leafy, terete, minutely pubescent often in 

 broad lines with subreflexo-patent subglandular hairs, terminally 1-3-flowered, 

 attaining about 6cm. in height; internodes usually longer than leaves. Leaves 

 rather dense, erect-patent or patulous, opposite, small, lato-ovate to elliptico- 

 ovate, but often oblong or ovato-oblong and smaller in inferior ones, acute 

 with a callose tip, sessile and very slightly vaginate, rounded obtuse or 

 acute at the base, entire, glabrous, but only slightly ciliated on basal margin, 

 thickish, green, attaining about 6^ mm. long, 4| mm. broad ; midrib 

 straight, glabrous dorsally ; veins inconspicuous, irregularly anastomosing. 

 Flower pedicellate, about 6-7 mm. across, white ; pedicel erect, strict, 

 minutely pubescent, longer than the calyx, about 5-10 mm. long in flower 

 but attaining about 13 ram. in fruit ; bract similar to the superior leaves. 

 Calyx 5-sepaled, glabrous but puberulent at the sulxjoncavo-truncate base ; 

 sepals erect-patent in flower but then erect, with a straight or scarcely 

 recurved tip, oblong-lanceolate, acuminate, entire, very loosely ciliated on 

 the basal margin, hardly scarious on margin, concave, herbaceous, somewhat 

 carinate with a glabrous edge dorsally, green, persistent, about 3^ mm. 

 long, 11 mm. wide; midrib straight; veins irregularly and very loosely 

 anastomosing. Petals 5, longer than sepals, ova to-lanceolate to trian- 

 gular-lanceolate, subacuminate with an obtuse tip or obtuse, suddenly 

 attenuated into a short claw, entire often subrepand, thinly membranaceous, 

 delicately and loosely vertical-veined, about 4^ ram. long, 1§-1| mm. wide. 

 Stamens 10, very slightly shorter than or equal to petals in height ; fila- 

 ment subulate, shortly dilated at the base, glabrous, white ; anther orbicular, 

 rosy before bursting. Disk 5-lobed, 5-glandular, thickish, connate with 

 tlie bases of filaments. Ovary ovoid-globose, substipitate, one-lccular, 

 .glabrous, green, about 1^ mm. across; carpel not thick; ovules subnumerous, 

 about 16-17, orbiculato-reniform, compressed, with a funicule ; styles 3, 

 lower than petals, filiform, longer than the ovary, erect-patent and arcuato- 

 recurved, about i-stigmatose ; stigma thickish towards the top, subclavate. 

 'Capsule ovoid-conical, obtuse, rounded at the base, subsessile, exceeding 

 the persistent calyx, straight, bursting into 6-dentato-lobed valves (narrowly 

 triangular in form with an obtuse apex) towards the top, 6-nerved, al)out 

 5mm. long; carpel smooth, not thick but coriaceous. Seeds rather many, 

 orbiculato-reniform, compressed, ferruginous, minutely tuberculate, angulate 

 or obtuse on dorsal edge, about 1 ram. or less long ; funicule thickish.
