Paraserianthes lophantha (syn. Albizia lophantha), the Cape Leeuwin wattle, Bicol wattle, Cape wattle, crested wattle or plume albizia, is a fast-growing tree with creamy-yellow, bottlebrush like flowers.[4] It is the sole species in genus Paraserianthes.[5]
It is a small tree (uppermost height approximately 5 metres) that occurs naturally along the
southwest coast of
Western Australia, from
Fremantle to
King George Sound.[6] It is also native to
Sumatra,
Java, and the
Lesser Sunda Islands.[3] It was first spread beyond southwest Australia by Baron
Ferdinand von Mueller, who gave packets of P. lophantha seeds to early explorers under the assumption that if they planted the seeds at their campsites, the trees would indicate the routes they travelled.[7]
It was first described in 1806 as Acacia lophantha by
Willdenow, but was transferred to the genus Paraserianthes by Nielsen, Guinet and Baretta-Kuipers in 1983.[1][2]
The genus Paraserianthes originally comprised four species, divided into two sections based on morphological traits by Nielsen.[10][11] Section Paraserianthes included P. lophantha with two recognized subspecies, and section Falcataria included three species (P. falcataria, P. pullenii, and P. toona).[10][11]
Based on morphology P. falcataria (L.) I.C.Nielsen was moved to the genus Falcataria by Barneby and Grimes,[12] and renamed Falcataria moluccana (Miq.) Barneby & J.W.Grimes.[12] Brown et al. used biogeographical, morphological and molecular studies to completely separate of these sections into two genera as Paraserianthes sensu Nielsen was
paraphyletic.[13] Now P. pullenii (Verdc.) I.C. Nielsen[10][11] = Falcataria pullenii (Verdc.) G.K. Brown, D.J. Murphy & P.Y. Ladiges;[13] and P. toona (F.M. Bailey) I.C. Nielsen[10][11] = Falcataria toona (Bailey), G.K. Brown, D.J. Murphy & P.Y. Ladiges.[13]Paraserianthes section remained in the genus with only Paraserianthes lophantha.[13]
