Phaneroglossa is a low, up to high, perennial plant that is hairless except for the woolly
leaf axils, and has short, woody, upwardly inclined stems. Its leaves are crowded on the short stems, leathery in consistency, and
set alternately along the stem. The leaves are line-, lance- or inverted lance-shaped, with a conspicuous
midvein, seated with the base more of less clasping the stem, with an entire margin or some shallow teeth, often slightly curving down, the tip tapering or ending abruptly in a small sharp point as a continuation of the midvein. The flower heads are set on top of long, stout, unbranched
stalks with few, scattered, awl-, line- or lance-shaped bracts. The flowerhead has an
involucre that is initially cup-shaped with a flat base, later becomes broadly cone-shaped, while the bracts eventually flip down to press against the stem when the seeds are ripe. It consists of a single whorl of eleven to fifteen lance-shaped, leathery bracts, with one or three
resin ducts tapering to a long point, that are merged at their base, with a distinct thin and dryish margin that has a fringe of soft hairs towards the tips. The
common base of the florets is flat and wide, without bracts at the foot of each floret, with a smooth surface except for regularly distributed indents where the florets are implanted. The
flower heads each have five to eight female
ray florets that consist of a closed tube at base and a strap nearer the top. The tube is cylinder-shaped and has a few to many blunt hairs, which are several rows of cells thick and are topped with
glands. The straps are white or cream-coloured,
elliptic or
obtuse in shape, mostly have four veins and is split in three teeth at the tip. From the mouth of the ray floret tube emerges a
style that splits in two outward curling, hairless branches each topped by an obtuse conical appendage. Surrounding the base of the ray floret corolla are many, white, barbed
pappus bristles which are quickly shed in the ray florets. At the base of the ray floret develop eventually dark brown to black, dry, one-seeded,
indehiscent fruits called
cypselae, which are oblong in shape, and have five or six wing-like, hairless ridges along their lengths. The ray florets surround many
bisexual disc florets with a yellow, tube-shaped
corolla that near its top splits star-like into five, outward curving oval lobes with a vein parallel to their margin, a central resin duct and a finely grainy surface near the tips. In the center of each
corolla are free
filaments, topped by five
anthers that are merged into a tube, through which the
style grows when the floret opens, hoovering up the
pollen on its shaft. The
anthers have an arrow-shaped base, and one large, oval appendage at their tip, that is wider than the anther. The filaments each have a distinct bulbous collar just below the anthers. The pappus of the disc florets is persistent, and the cypselae are narrowly oblong, and have always five wings covered with blunt hairs that become slimy when wet. ==Taxonomy==
