Very near S. Russellianum, differing mainly by the smaller calyx and corolla and 
narrower bracts. Bract iin. Calyz scarcely l in., divided half-way down. Stamens 
2 only in n. 68 H. f. & T.; when T. Anderson says 4, he must have examined Wall.

XVII. ZECHMANTHERA, Nees. 
Small, hairy shrubs. Leaves broad-elliptic acute, crenate, often viscid. 
Clusters of flowers sessile on the branches of a trichotomous or 1-sided 
panicle, distant or close; bracts linear, as long as the calyx; bracteoles 
similar smaller. Calyx sub-5-partite; segments linear, subequal. Corolla 
tubular-ventricose, nearly straight, widened suddenly near the middle, 
glabrous, 2 hairy lines on the palate within; segments 5, subequal, rounded, 
twisted to the left in bud, pale-violet or purplish. Stamens 4, didynamous, 
included, longer filaments hairy, shorter glabrous; anthers subsimilar, 
ovate or oblong, 2-celled, cells muticous; connective excurrent at the tip or 
not. Ovary densely hairy at the apex; style sparsely hairy thickened up- 
wards, stigma large simple linear-lanceolate; ovules 4-6 in each cell. 
Capsule narrowly oblong, 6-8- (or ex Benth. 12-) seeded from the base, 
retinacula strong, hooked. Seeds discoid, densely hairy, or thicker glabrous.

as long as the calyx or more often about half as long. Sepals 1-3 in., linear-ligulate, 
somewhat unequal, herbaceous, pubescent, usually viscous. Corolla 1 in. Anthers

even in the buds just before expansion. Capsule | in., 8-seeded; hairs of the seeds 
starting out when wetted. .
