Corymbium

Corymbium is a genus of flowering plants in the daisy family comprising nine species. It is the only genus in the subfamily Corymbioideae and the tribe Corymbieae. The species have leaves with parallel veins, strongly reminiscent of monocots, in a rosette and compounded inflorescences may be compact or loosely composed racemes, panicles or corymbs. Remarkable for species in the daisy family, each flower head contains just one, bisexual, mauve, pink or white disc floret within a sheath consisting of just two large involucral bracts. The species are all endemic to the Cape Floristic Region of South Africa, where they are known as plampers.

== Description == thumb|left|Corymbium has unusual long Cypsela (botany)|cypselae covered in very long hairsThe species of Corymbium are monoecious, stemless, perennial, herbaceous plants of high, that grow in tufts and look like a monocotyledon as long as they are not flowering. The plants have a fibrous rhizome that is covered the persisting bases of old leaves and long, soft, silky hairs. Most parts of the plants may be covered in long soft hairs, or coarse hairs or lack indumentum. All leaves are in a basal rosette and lack a discernable stalk. If the leaves are covered with glandular hairs, they are sticky. The leaf blades may be circular in cross-section, flat or the margins may be curved upward, have a line-shaped to broadly elliptic or lance-shaped outline, with a pointy tip or tapering, the base much narrowed, like a leaf stalk. The leaf margins are entire. The leaves may have prominent or more or less obscured parallel veins, and the leaf surfaces may be hairless, or carry long soft or coarse hairs. The texture of the leaves may be cartilaginous, leathery or herbaceous. The flowers are at the end of one or several branching inflorescence stalks, that carry several bracts much smaller than the leaves, at least subtending each of the branches. These inflorescence stalks may be roughly hairy to hairless, and round or angular in cross-section. The compounded inflorescences may be compact or loosely composed racemes, panicles or corymbs. Each head is on a very short or long pedicel, except in C. cymosum, where it is absent.
