Paulowniaceae are a family of flowering plants within the Lamiales. [2] They are a monophyletic and monogeneric family of trees with currently 7 confirmed species. [3] They were formerly placed within Scrophulariaceae sensu lato , [4] or as a segregate of the Bignoniaceae. [5]

Contents

The Paulowniaceae are now resolved as a distinct separate family consisting of the genus Paulownia . They are deciduous trees with large heart shaped leaves and long panicles of white-purple to lavender flowers native to eastern Asia. The most widely distributed and recognized species is Paulownia tomentosa with common names such as Princess tree, Empress tree, Kiri tree, Foxglove tree, and Phoenix tree.

Taxonomy

There are 7 confirmed species of Paulownia with potentially more as hybrid, variety, or mismatched synonym species. [3]

Phylogeny

Paulowniaceae is sister to the Orobanchaceae, a primarily hemi-holoparasitic plant family, except for the clade of herbaceous genera Lindenbergia , Rehmannia , and Triaenophora . This clade of non-parasitic plants within Orobanchaceae are most closely related to Paulownia. Sister to the Orobanchaceae-Paulowniaceae clade is Phrymaceae. [3] Phrymaceae are mostly herbaceous plants with a widespread distribution.

As of August 2017, The Plant List accepted four genera in the family. [6] However of these four genera currently only Paulownia is a recognized member of Paulowniaceae.

The Scrophulariaceae are a family of flowering plants, commonly known as the figwort family. The plants are annual and perennial herbs, as well as shrubs. Flowers have bilateral (zygomorphic) or rarely radial (actinomorphic) symmetry. The Scrophulariaceae have a cosmopolitan distribution, with the majority found in temperate areas, including tropical mountains. The family name is based on the name of the included genus Scrophularia L.

Gesneriaceae, the gesneriad family, is a family of flowering plants consisting of about 152 genera and ca. 3,540 species in the tropics and subtropics of the Old World and the New World, with a very small number extending to temperate areas. Many species have colorful and showy flowers and are cultivated as ornamental plants.

<span class="mw-page-title-main">Plantaginaceae</span> Family of flowering plants in the order Lamiales

Plantaginaceae, the plantain family, is a large, diverse family of flowering plants in the order Lamiales that includes common flowers such as snapdragon and foxglove. It is unrelated to the banana-like fruit also called "plantain." In older classifications, Plantaginaceae was the only family of the order Plantaginales, but numerous phylogenetic studies, summarized by the Angiosperm Phylogeny Group, have demonstrated that this taxon should be included within Lamiales.

<i>Paulownia</i> Genus of flowering plants in the family Paulowniaceae

Paulownia is a genus of seven to 17 species of hardwood tree in the family Paulowniaceae, the order Lamiales. The genus, originally Pavlovnia but now usually spelled Paulownia, was named in honour of Anna Pavlovna, queen consort of The Netherlands (1795–1865), daughter of Tsar Paul I of Russia. It is also called "princess tree" for the same reason.

<span class="mw-page-title-main">Orobanchaceae</span> Family of flowering plants known as broomrapes

Orobanchaceae, the broomrapes, is a family of mostly parasitic plants of the order Lamiales, with about 90 genera and more than 2000 species. Many of these genera were formerly included in the family Scrophulariaceae sensu lato. With its new circumscription, Orobanchaceae forms a distinct, monophyletic family. From a phylogenetic perspective, it is defined as the largest crown clade containing Orobanche major and relatives, but neither Paulownia tomentosa nor Phryma leptostachya nor Mazus japonicus.

<span class="mw-page-title-main">Phrymaceae</span> Family of flowering plants

Phrymaceae, also known as the lopseed family, is a small family of flowering plants in the order Lamiales. It has a nearly cosmopolitan distribution, but is concentrated in two centers of diversity, one in Australia, the other in western North America. Members of this family occur in diverse habitats, including deserts, river banks and mountains.

<i>Rehmannia</i> Genus of flowering plants in the broomrape family Orobanchaceae

Rehmannia is a genus of seven species of flowering plants in the order Lamiales and family Orobanchaceae, endemic to China. It has been placed as the only member of the monotypic tribe Rehmannieae, but molecular phylogenetic studies suggest that it forms a clade with Triaenophora. Contrary to the immense majority of the taxa of Orobanchaceae, Rehmannia is not parasitic.

<span class="mw-page-title-main">Calceolariaceae</span> Family of flowering plants

Calceolariaceae is a family of flowering plants in the order Lamiales that has been recently segregated from Scrophulariaceae. The family includes three genera, Calceolaria, Porodittia, and Jovellana, but analysis suggests that the monotypic Porodittia should be placed within Calceolaria. Recent molecular phylogenies that included Calceolaria have shown not only that this genus does not belong in Scrophulariaceae but also that it is the sister clade to the majority of the other families of the Lamiales. Morphological and chemical characters also support the separation of Calceolariaceae from Scrophulariaceae and other Lamiales. Some recent studies have supported a sister-group relationship between Calceolariaceae and Gesneriaceae. Given this close relationship, some authors opt to merge this family into Gesneriaceae as subfamily Calceolarioideae

The APG system of plant classification is the first version of a modern, mostly molecular-based, system of plant taxonomy. Published in 1998 by the Angiosperm Phylogeny Group, it was replaced by the improved APG II in 2003, APG III system in 2009 and APG IV system in 2016.

Verbascoside is a caffeoyl phenylethanoid glycoside in which the phenylpropanoid caffeic acid and the phenylethanoid hydroxytyrosol form an ester and an ether bond respectively, to the rhamnose part of a disaccharide, namely β-(3′,4′-dihydroxyphenyl)ethyl-O-α-L-rhamnopyranosyl(1→3)-β-D-(4-O-caffeoyl)-glucopyranoside.

Brandisia is a genus of flowering plants in the family Orobanchaceae.

Wightia is a genus of flowering plants tentatively sister to the Phrymaceae which currently contains only two species. It grows as a tree, or a hemiepiphytic pseudo-vine, up to 15 metres (49 ft) tall. It is found in South Asia and South East Asia, from Nepal and India to Thailand, Vietnam and China's Yunnan Province, at altitudes below 2,500 m (8,200 ft). There are still morphological characters as well as nuclear genome data to support Wightia as sister to Paulownia leading it to be of proposed hybrid origin from Phrymaceae and Paulowniaceae. Due to chloroplast and mitochondrial data showing Wightia as sister to Phrymaceae it is proposed that a new family Wightiaceae be recognized.

<span class="mw-page-title-main">Mazaceae</span> Family of flowering plants

Mazaceae is a family of plants in the order Lamiales. The family was described by James L. Reveal in 2011. Genera in this family were most recently previously included in Phrymaceae and in older classifications were placed in Scrophulariaceae.

Cyrtandromoea is a genus of flowering plants belonging to the family Phrymaceae. For a considerable time, the family placement of the genus remained uncertain; it was placed in either Gesneriaceae or Scrophulariaceae. A molecular phylogenetic study published in 2019 showed that it belonged in Phrymaceae.
