'''''Xeronema''''' is a [[genus]] of [[flowering plant]]s containing two species, ''[[Xeronema moorei]]'' from [[New Caledonia]], and ''[[Xeronema callistemon]]'' (the Poor Knights lily) from the [[Poor Knights Islands]] and [[Hen and Chicken Islands|Taranga Island]] in [[New Zealand]]. The plants are herbaceous [[monocots]], spreading by [[rhizomes]], and have large flowers set on terminal spikes, with stamens towering above the flowers.

The type species ''X. moorei'' is found in the mountains of New Caledonia.

The Poor Knights lily (''X. callistemon'') is endemic to the Poor Knights Islands and Taranga Island in the north of New Zealand. It was discovered in 1924. The Poor Knights lily has large bottlebrush [[flower]] clusters that grow horizontally. The clusters begin growing vertically and then bend sideways. Bright red flowers grow upward from the stalk, with bright orange [[pollen]].  The plant can reach a height of one metre tall and across.

The [[APG IV system]], of 2016, accepts this genus as constituting its own [[Family (biology)|family]] '''Xeronemataceae'''. It places this in the [[Order (biology)|order]] [[Asparagales]], in the clade [[monocots]].<ref name = APG4 /> The family can be separated from other Asparagales families on DNA evidence; it is related to [[Asphodelaceae]] but differs in having uniformly unifacial leaves like [[Iridaceae]].<ref name=ChaseEtAl />
