64. LXXV. RUBIACEX. (J. D. Hooker.) [ Oldenlandia. 
ANOMALOUS SPECIES, 
57. H. andamanica, Kurz in Journ. As. Soc, 1872, ii. 311; annual. 
succulent, stems furfuraceous, short stout, leaves large sessile or short-petioled 
oblong or ovate-oblong apiculate flat, stipules bristly, cymes terminal 1-3 in. 
long, peduncles erect, flowers subcapitate, calyx-teeth longer than the corolla~ 
tube and than the small didymous capsule, 
Sourn ANDAMAN and Nicobar Istanps, Kurz. 
Stems 4-6 in. high, erect, simple or branched. Leaves 3-5 pair, 1-23 by $-1} in.,. 
membranous, quite glabrous. Peduncles 1-2 in., slender, strict, erect, bearing 2-3 
small bracteate heads of subsessile flowers. Calyx-tube short; teeth large, ovate- 
lanceolate, recurved. Corolla funnel-shaped; tube broad and glabrous; mouth with 
a few hairs; lobes linear, Stamens much exserted, anthers linear. Capsule with the 
crown not protruded, gaping loculicidally. Seeds many in each cell, angular, smooth. 
—Resembles an Oldenlandia near O. nudicaulis, but the calyx-teeth are close together 
in fruit, and the seeds, though not ripe, have no appearance of pitting; the corolla, 
too, resembles that of Hedyotis, and the stamens have linear anthers. 
21. OLDENLANDIA, Z. 
Slender erect or diffuse di-tri-chotomously branched herbs. Leaves usually 
small and narrow; stipules acute or bristly. Flowers small, white or pink, in 
dichotomous axillary and terminal usually panicled cymes, rarely solitary. 
Calyx-teeth 4, rarely 5, usually erect and distant in fruit, with sometimes alter- 
nating teeth. Corolla rotate funnel- or salver-shaped, tube short or long; 
lobes 4, rarely 5, obtuse, valvate. et d 2-celed; style filiform, stigmas 2 
linear; ovules numerous, placentas attached to the septum. Capsule small, 
usually membranous, terete didymous or angled, loculicidal at the top, rarely 
indehiscent, many-seeded. Seeds angled or globose, testa not winged, smooth or 
pitted ; embryo clavate in fleshy albumen.—Disrrrs. Species about 70, tropical 
and subtropical, chiefly Asiatic. 
Svserx. I. Euoldenlandia. Corolla-tube usually short, ovary terete. 
Capsule didymous. Seeds numerous, angled, testa smooth,—Herbs, diffuse or 
branching, usually very slender, stipules with bristles.

An abundant weed throughout Inp1a, from the Punjab southward and eastward 
to Ceylon and Malacca.—Distrin. Tropical E. Asia to Java and the Philippines; 
Trop. Africa and America. 
Very variable, not always distinguishable from O. diffusa and O. Heynii. It 
varies from a diminutive straggling herb, with branches 1-2 in., to an erect one a foot 
and more high. Leaves from 4-2 by 4-4 in., erect spreading or recurved, sometimes.
