600 LXix. RUBiACE^. [Authosjiermum 



ternate, I'athei' slender, usually virgate, somewhat woody sub- 

 terete and sub-glabrate below, puberulous with very short dense 

 thick whitish hairs on a reddish bark above ; middle internodes 

 about equalling the spreading leaves ; upper internodes gradually 

 shorter and not as long as the leaves : leaves verticillate 3 together 

 or opposite, with very abbreviated leafy branchlets in the axils 

 giving the leaves a fasciculate appearance, spathulate-linear or 

 very narrowly so in consequence of the margins being broadly 

 revolute towards the midrib, apiculate at the apex, narrowed 

 gradually towards the sessile or sub-sessile base, glabrous or veiy 

 nearly so, rigid, spreading, 1 -nerved, ^ to 1^ in. long; stipules 

 adnate to and viniting in a short sheath the leaf-bases or short 

 petioles, truncate and uni-cuspidate or lanceolate-linear from a 

 broad sub-truncate base, minutely puberulous outside, sub- 

 persistent ; flowers apparently unisexual ; female flowers tetra- 

 merous, sessile or sub-sessile; calyx-limb very small, with incon- 

 spicuous teeth ; corolla salver-shaped, very small, sub-persistent ; 

 the tube slender, glabrous, about ^ in. long ; the lobes scattered 

 with a few hairs at the back, oblong-lanceolate, obtuse, valvate 

 in the bud, induplicately so at the apex, longer than the tube, 

 reflexed in open flower ; stamens 4, exserted, glabrous ; anthers 

 rather small, effete ; filaments filiform, inserted about the mouth 

 of the corolla-tube ; style puberulous, shortly exsei-ted, 2-lobed at 

 the apex, filiform ; fruit dicoccous, dry, puberulous, ■— in. long. 

 Male flowers unknown.

A robust sufi"ruticose herb ; stem erect, reddish, glabrate, closely 

 branched, 1 to 2 ft. high or more ; branches spreading at an angle 

 of about 45° with the stem, puberulous towards the extremities, 

 densely leafy ; leaves sub-linear or sub-spathulate, apiculate at the 

 apex, narrowed gradually to the sub-sessile base, uni-nerved at 

 the base, glabrous or very nearly so, minutely or obsoletely scaly 

 especially beneath, rigid, opposite, with abbreviated leafy branch- 

 lets in the axils giving the leaves a fasciculate appearance, ^ to 

 1\ in. long , margins revolute ; stipules truncate, 3- to 5-cuspidate, 

 joining the very short petioles or leaf -bases ; flowers sub-sessile, 

 tetramerous, whitish, small ; calyx-limb green, quadripartite ; the 

 segments lanceolate or subulate, shorter than the corolla-tube in 

 the male flowers, glabrous ; corolla of the male flowers f unnel- 

 sbaped ; the lobes lanceolate, twice as long as the tube, valvate in 

 the bud, spreading in full flower ; stamens 4, glabrous ; anthers 

 ellipsoidal-oblong ; cells 2, separated at the base for some distance
