19. Arenaria (Pentadenaria, Rariflorae) Katoana Makino, Le, p. 88. 
Perennial, caespitoso-diffuse. Stems numerous, gracile; the lower 
portion 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 sub- 
glandular hairs, terminally 1—3-flowered, attaining about 6 cm 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 6/3 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 mm in fruit; bract similiar to the superior leaves. 
Calyx 5-sepaled, glabrous but puberulent at the subconcavo-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, 1!⁄ mm wide; midrib straight; veins 
irregularly and very loosely anastomosing. Petals 5, longer than sepals, 
ovato-lanceolate to triangular-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 
41/, mm long, 1?/,—1!/, mm wide. Stamens 10, very slightly shorter 
than or equal to petals in height; filament subulate, shortly dilated at 
the base, glabrous, white; anther orbicular, rosy before bursting. Disk 
5-lobed, 5-glandular, thickish, connate with the bases of filaments. Ovary 
ovoid-globose, substipitate, one-locular, glabrous, green, about 11}, 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 !/,stig- 
matose; 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, about 5 mm
