How is Kurtz’s African mistress described?

From the text:

"And from right to left along the lighted shore moved a wild and gorgeous apparition of a woman.

"She walked with measured steps, draped in striped and fringed cloths, treading the earth proudly, with a slight jingle and flash of barbarous ornaments. She carried her head high; her hair was done in the shape of a helmet; she had brass leggings to the knee, brass wire gauntlets to the elbow, a crimson spot on her tawny cheek, innumerable necklaces of glass beads on her neck; bizarre things, charms, gifts of witch-men, that hung about her, glittered and trembled at every step. She must have had the value of several elephant tusks upon her. She was savage and superb, wild-eyed and magnificent; there was something ominous and stately in her deliberate progress. And in the hush that had fallen suddenly upon the whole sorrowful land, the immense wilderness, the colossal body of the fecund and mysterious life seemed to look at her, pensive, as though it had been looking at the image of its own tenebrous and passionate soul.

"She came abreast of the steamer, stood still, and faced us. Her long shadow fell to the water's edge. Her face had a tragic and fierce aspect of wild sorrow and of dumb pain mingled with the fear of some struggling, half-shaped resolve. She stood looking at us without a stir and like the wilderness itself, with an air of brooding over an inscrutable purpose."
