The Tribe Wisterieae (Zhu 1994), founded on the single genus Wisteria, is emended and recircumscribed based on morphology and data from nuclear ITS and ndhJ-trnF, matK and rbcL chloroplast DNA sequences. This newly enlarged tribe comprises 36 species and 9 infraspecific taxa within 13 described genera. Six genera are new, two are reinstated and five were previously placed in Tribe Millettieae. The genus Adinobotrys is also reinstated comprising two species including the new combination A.vastus. Other reinstated genera include Whitfordiodendron, with four species, and Padbruggea, with three species, including the reinstatement of P.filipes and the new combination P.filipesvar.tomentosa. The existing genera Afgekia, Callerya, Endosamara (with the new combination E.racemosavar.pallida), Sarcodum and Wisteria, with the new combinations W.frutescenssubsp.macrostachya are evaluated. The new genera comprise three Australasian species in Austrocallerya: A.australis, A.megasperma and A.pilipes; Wisteriopsis with five species from east Asia has six new combinations: W.japonica, W.kiangsiensis, W.championii, W.eurybotrya, W.reticulata and W.reticulatavar.stenophylla. Two species comprise the new Thai genus Kanburia: K.tenasserimensis and K.chlorantha. Nanhaia comprises the two species: N.fordii and N.speciosa and the monotypic genera Sigmoidala and Serawaia are based respectively on the species S.kityana and S.strobilifera. Lectotypes are designated for the names Adinobotrysfilipes, A.myrianthus, Millettiabonatiana, Millettiabracteosa, Millettiachampionii, Millettiacinerea, Millettiadielsiana, Millettiakityana, M.maingayi, Millettianitida, Millettiaoocarpa, Millettiapurpurea, M.reticulata, M.reticulatavar.stenophylla, Padbruggeadasyphylla, Pterocarpusaustralis, Robiniaracemosa, Whitfordiodendronscandens, W.sumatranum and Wisteriapallida. A neotype is designated for the name Millettialeiogyna.

The first complete chloroplast genome sequence for Narcissus is assembled and annotated in this study. The total length of the N. poeticus chloroplast genome is 160,099 bp and comprises the large single copy (LSC) spanning 86,445 bp, the small single copy (SSC) spanning 16,434 bp, and two inverted repeat regions each of 28,610 bp length. The truncated copy of ycf1 before the junction between IR B and SSC was 1277–2428 bp longer than in other included Asparagales samples. A potential pseudogene, cemA , was also identified. This is the first reported plastome for Amaryllidaceae subfamily Amaryllidoideae.

Amaryllidaceae is a widespread and distinctive plant family contributing both food and ornamental plants. Here we present an initial survey of plastomes across the family and report on both structural rearrangements and gene losses. Most plastomes in the family are of similar gene arrangement and content however some taxa have shown gains in plastome length while in several taxa there is evidence of gene loss. Strumaria truncata shows a substantial loss of ndh family genes while three other taxa show loss of cemA, which has been reported only rarely. Our sparse sampling of the family has detected sufficient variation to suggest further sampling across the family could be a rich source of new information on plastome variation and evolution.
