Delairea odorata
species of plant
Delairea odorata is a climber within the family Asteraceae that is native to South Africa. One of the two species in the genus Delairea (the other being Delairea aparadensis), it was previously included in the genus Senecio as Senecio mikanioides. It is known as Cape ivy in some parts of the world (US) and German ivy in others (Britain, Ireland). Other names include parlor ivy and Italian ivy.
It is a twining perennial, herbaceous plant that grows 3 metres (9.8 ft) tall. Its multi-lobed leaves somewhat resemble those of the unrelated English ivy. Originally used as an ornamental plant on trellises and as groundcover, it is now rarely cultivated because of its invasiveness, in addition to being a weed. Although it resembles Senecio tamoides, Open Tree of Life indicates that it is most closely related to species in the genus Curio, followed by Senecio angulatus.
Description
Delairea odorata is a fast-growing vine that can climb to heights of 2–4 metres (7–13 ft).
The glossy and semi-succulent leaves, which are 3–10 centimetres (1+1⁄4–4 in) long and 3–8 centimetres (1+1⁄4–3+1⁄4 in) wide, are alternately arranged along the stems.

Why this record matters
The phrase “species of plant” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q2702202. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
