Inflorescence and flower features. Flowers aggregated in ‘inflorescences’, or solitary; not crowded at the stem bases. Inflorescence few-flowered. Flowers in cymes. Inflorescences simple; terminal (or opposite the upper leaves). Flowers pedicellate (, pedicels articulate near middle in K. velutina); ebracteate; bracteolate; small; regular; not resupinate; neither papilionaceous or pseudo-papilionaceous; 4 merous, or 5 merous; cyclic; tricyclic, or tetracyclic (usually). Floral receptacle with neither androphore nor gynophore. Perianth with distinct calyx and corolla; 4, or 5, or 10; 1 -whorled, or 2 -whorled; isomerous. Calyx present; 4, or 5; 1 -whorled; gamosepalous; lobed. Calyx lobes markedly shorter than the tube. Calyx hairy (densely stellate hairy); valvate; exceeding the corolla (when corolla is present); broad; regular; neither appendaged nor spurred; pink, or purple. Epicalyx absent. Corolla vestigial, or absent; 5 (scale-like when present); 0 -whorled, or 1 -whorled. Androecium present. Fertile stamens present. Androecial members definite in number. Androecium 5–10. Androecial members free of the perianth; free of the gynoecium; markedly unequal; free of one another, or coherent (stamens and staminodes shortly connate at the base into staminal tube); 1 - adelphous; 1 -whorled. Androecium exclusively of fertile stamens, or including staminodes. Staminodes 5 (when present); non-petaloid. Stamens 5; all more or less similar in shape; isomerous with the perianth; alternisepalous; filantherous. Anthers separate from one another; all alike; dehiscing via longitudinal slits; bilocular. Fertile gynoecium present. Gynoecium 3–5 carpelled. The pistil 3–5 celled. Carpels reduced in number relative to the perianth, or isomerous with the perianth. Gynoecium syncarpous; synovarious, or synstylovarious, or eu-syncarpous; superior. Ovary plurilocular; 3–5 locular; subsessile. Ovary summit glabrous, or hairy, the hairs not confined to radiating bands. Gynoecium stylate. Styles 3–5; free, or partially joined; simple; apical. Placentation axile.
