Leea (Tagalog: Talyantan) is a genus of plants that are distributed throughout northern and eastern Australia, New Guinea, south and southeast Asia and parts of Africa. The APG IV system places Leea in the subfamily Leeoideae (Vitaceae). [2] [ irrelevant citation ]Leea is now placed in the family Vitaceae having previously been placed in its own family, Leeaceae, based on morphological differences between it and other Vitaceae genera. These differences include ovule number per locule (two in Vitaceae and one in Leeaceae), carpel number (two in Vitaceae and three in Leeaceae), and the absence or presence of a staminoidal tube (present in Leeaceae) and floral disc (present in Vitaceae). Pollen structure has also been examined for taxonomic demarcation, though studies have concluded that the pollen of Leeaceae and Vitaceae suggests the families should remain separate while other studies conclude that Leea should be included in Vitaceae. [3]

Contents

The genus was named by Linnaeus after James Lee, the Scottish nurseryman based in Hammersmith, London who introduced many new plant discoveries to England at the end of the 18th century. [4]

Ecology

Leea flowers are visited by a variety of potential insect pollinators, including flies, wasps, bees, butterflies, and beetles. Some species may have evolved synchronized dichogamy as a mechanism to prevent self pollination. [5]

Species

Plants of the World Online accepts the following 45 species in this genus as of 12 July 2023 . [1]

<i>Aeschynanthus</i> Genus of flowering plants in the family Gesneriaceae

Aeschynanthus is a genus of about 150 species of evergreen subtropical and tropical plants in the family Gesneriaceae. They are usually trailing epiphytes with brightly colored flowers that are pollinated by sunbirds. The genus name comes from a contraction of aischuno and anthos (flower). The common name for some species is lipstick plant, which comes from the appearance of the developing buds emerging from the calyces. A full list of the accepted species and their synonyms can be found in the Smithsonian Institution's World Checklist of Gesneriaceae.

<i>Macaranga</i> Genus of tropic trees

Macaranga is a large genus of Old World tropical trees of the family Euphorbiaceae and the only genus in the subtribe Macaranginae. Native to Africa, Australasia, Asia and various islands of the Indian and Pacific Oceans, the genus comprises over 300 different species.

<i>Tetrastigma</i> Genus of grapevines

Tetrastigma is a genus of plants in the grape family, Vitaceae. The plants are lianas that climb with tendrils and have palmately compound leaves. Plants are dioecious, with separate male and female plants; female flowers are characterized by their four-lobed stigmas. The species are found in subtropical and tropical regions of Asia, Malaysia, and Australia, where they grow in primary rainforest, gallery forest and monsoon forest and moister woodland. Species of this genus are notable as being the sole hosts of parasitic plants in the family Rafflesiaceae, one of which, Rafflesia arnoldii, produces the largest single flower in the world. Tetrastigma is the donor species for horizontal gene transfer to Sapria and Rafflesia due to multiple gene theft events.
