Jovellana is a genus of flowering plants in the family Calceolariaceae. It was formerly included in Scrophulariaceae, and is still listed by some authorities as belonging there. However, recent molecular research indicates that the family Scrophulariaceae was polyphyletic, [3] meaning that it contained more than one lineage with different parents. So several of its genera - including Jovellana - have been split off and assigned to new or existing families.

History

During the Miocene epoch, the climate of the North Island of New Zealand was said to be subtropical. It started to cool down during the Late Miocene and Pliocene to a more temperate climate which was similar to that of central Chile. This may have allowed the South American elements of the Jovellana genus to establish their characteristics by long distance dispersal. [4]

The South American and New Zealand clades are believed to have split 4.1 Ma and both New Zealand and South American species are believed to have diverged from one another about 1.0 Ma. [4]

Description

Jovellana currently contains six to eight species of mainly herbaceous perennials native to Chile and New Zealand. They have simple leaves and, in summer, nodding sprays of single, two-lipped, bell-shaped flowers in shades of white, lilac and purple, heavily spotted with a contrasting colour inside. [5]

The following species are currently included: [6]

Distribution

Authorities have commented on the disjunct nature of the two populations in Chile and New Zealand. However, this is not unique. Fuchsia is another genus with species apparently randomly segregated between Central and South America, New Zealand and Tahiti. [7]

Cultivation

At least three species are cultivated as ornamental garden plants. They are frost-hardy down to −5 °C (23 °F), but in cultivation they require a sheltered position in full sun. [5] Jovellana violacea, growing to 2.5 m (8.2 ft) tall by 1 m (3.3 ft) broad, is a semi-evergreen subshrub with lilac coloured flowers, internally spotted with purple on a yellow background. It has gained the Royal Horticultural Society’s Award of Garden Merit. [8] [9]

Lamiales Order of dicot flowering plants

The Lamiales are an order in the asterid group of dicotyledonous flowering plants. It includes about 23,810 species, 1,059 genera, and is divided into about 24 families. Being one of the largest orders of flowering plants, Lamiales have representatives found all over the world. Well-known or economically important members of this order include lavender, lilac, olive, jasmine, the ash tree, teak, snapdragon, sesame, psyllium, garden sage, and a number of table herbs such as mint, basil, and rosemary. Lamiales and Orobanchaceae are both the largest populated parasitic angiosperms of flowering plants.

Oleaceae Family of flowering plants

Oleaceae, also known as the olive family, is a taxonomic family of flowering shrubs, trees, and a few lianas in the order Lamiales, It presently comprises 28 genera, one of which is recently extinct. The extant genera include Cartrema, which was resurrected in 2012. The number of species in the Oleaceae is variously estimated in a wide range around 700. The flowers are often numerous and highly odoriferous. The family has a subcosmopolitan distribution, ranging from the subarctic to the southernmost parts of Africa, Australia, and South America. Notable members include olive, ash, jasmine, and several popular ornamental plants including privet, forsythia, fringetrees, and lilac.

Scrophulariaceae Figwort family of flowering plants

The Scrophulariaceae are a family of flowering plants, commonly known as the figwort family. The plants are annual and perennial herbs, as well as one genus of 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.

<i>Linaria</i> Genus of flowering plants in the family Plantaginaceae

Linaria is a genus of 150 species of flowering plants, one of several related groups commonly called toadflax. They are annuals and herbaceous perennials, and the largest genus in the Antirrhineae tribe of the plantain family Plantaginaceae.

Gesneriaceae Family of flowering plants including African violets

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.

<i>Lysimachia</i> Genus of flowering plants in the family Primulaceae

Lysimachia is a genus consisting of 193 accepted species of flowering plants traditionally classified in the family Primulaceae. Based on a molecular phylogenetic study it was transferred to the family Myrsinaceae, before this family was later merged into the Primulaceae.

<i>Monarda</i> Genus of flowering plants

Monarda is a genus of flowering plants in the mint family, Lamiaceae. The genus is endemic to North America. Common names include bergamot, bee balm, horsemint, oswego tea, the first inspired by the fragrance of the leaves, which is reminiscent of bergamot orange. The genus was named for the Spanish botanist Nicolás Monardes, who wrote a book in 1574 describing plants of the New World.

Phrymaceae 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 six species of flowering plants in the order Lamiales and family Orobanchaceae, endemic to China. It is the only member of the monotypic tribe Rehmannieae. Contrary to the immense majority of the taxa of Orobanchaceae, Rehmannia is not parasitic.

Calceolariaceae 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

Linderniaceae Family of flowering plants

Linderniaceae is a family of flowering plants in the order Lamiales, which consists of about 25 genera and 265 species occurring worldwide. Vandellia micrantha is eaten in Laos, but tastes bitter.
