Simarouba is a genus of trees and shrubs in the family Simaroubaceae, native to the neotropics. It has been grouped in the subtribe Simaroubina along with the Simaba and Quassia genera. They have compound leaves, with between 1 and 12 pairs of alternate pinnate leaflets. Their flowers are unisexual, relatively small (around 1 cm long) and arranged in large panicles. Plants are dioecious, bearing only male or female flowers. [2] The individual flowers have between 4 and 6 sepals and petals and between 8 and 12 stamens. The fruit is a carpophore and has up to 5 drupaceous mericarps.


In 1944, Adolf Engler and Arthur Cronquist separated the species in the genus, [3] based mainly on the morphology of their flowers, but also using differences in their leaf structure. S. amara, S. glauca and S. versicolor are continental tree species and are often confused with each other, particularly in areas where more than one species is present in the flora. S. amara can be distinguished by having smaller flowers and anthers than S. glauca and S. versicolor and by it having straight, rather than curved petals; its fruit are also smaller. S. glauca can be distinguished by the lack of trichomes on its leaves compared with those of S. versicolor, which has dense tomentose leaves. S. versicolor has a greater variation in flower size than S. glauca and the leaf veins of S. glauca are generally more evident than those of S. versicolor. Geographically, S. glauca and S. versicolor are easy to distinguish since the southerly range of S. glauca is limited to Panama, whereas S. versicolor is only found in South America. [3] [4] A phylogenetic analysis in 1995 based on the large sub-unit of rubisco suggested that Simarouba was most closely related to the Leitneria and Ailanthus genera, [5] but a later study in 2007, based on three chloroplastic genes and one nuclear gene, [6] found it was most closely related to Pierreodendron and Simaba .

Discovery and uses

In 1713, the genus was discovered by French explorers. Between 1718 and 1725, the bark was exported to France where it was used to treat an epidemic of dysentery. The bark of Simarouba species has been used by indigenous tribes as a tea to treat many diseases. [8] [9] The seeds of Simarouba glauca have been proposed as suitable for producing edible oils in India. [10] Simarouba amara is harvested for timber, with its bright and lightweight timber being highly sought after in European markets to use in making fine furniture and veneers. [11] Simarouba glauca , also known as Lakshmi Taru in India, is also valued for its wood.

Ecology

The alianthus webworm ( Atteva aurea ) is a pest of the genus Simarouba. [12]

The Ericales are a large and diverse order of dicotyledons. Species in this order have considerable commercial importance including for tea, persimmon, blueberry, kiwifruit, Brazil nuts, argan, and azalea.

<span class="mw-page-title-main">Flowering plant</span> Clade of seed plants that produce flowers

Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae, commonly called angiosperms. They include all forbs, grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / angeion and σπέρμα / sperma ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta.

Quassia is a plant genus in the family Simaroubaceae. Its size is disputed; some botanists treat it as consisting of only one species, Quassia amara from tropical South America, while others treat it in a wide circumscription as a pantropical genus containing up to 40 species of trees and shrubs.

<i>Acorus</i> Genus of aquatic plants

Acorus is a genus of monocot flowering plants. This genus was once placed within the family Araceae (aroids), but more recent classifications place it in its own family Acoraceae and order Acorales, of which it is the sole genus of the oldest surviving line of monocots. Some older studies indicated that it was placed in a lineage, that also includes aroids (Araceae), Tofieldiaceae, and several families of aquatic monocots. However, modern phylogenetic studies demonstrate that Acorus is sister to all other monocots. Common names include calamus and sweet flag.

The Simaroubaceae are a small, mostly tropical, family in the order Sapindales. In recent decades, it has been subject to much taxonomic debate, with several small families being split off. A molecular phylogeny of the family was published in 2007, greatly clarifying relationships within the family. Together with chemical characteristics such as the occurrence of petroselinic acid in Picrasma, in contrast to other members of the family such as Ailanthus, this indicates the existence of a subgroup in the family with Picrasma, Holacantha, and Castela.

<i>Simarouba amara</i> Species of tree in the family Simaroubaceae

Simarouba amara is a species of tree in the family Simaroubaceae, found in the rainforests and savannahs of South and Central America and the Caribbean. It was first described by Aubl. in French Guiana in 1775 and is one of six species of Simarouba. The tree is evergreen, but produces a new set of leaves once a year. It requires relatively high levels of light to grow and grows rapidly in these conditions, but lives for a relatively short time. In Panama, it flowers during the dry season in February and March, whereas in Costa Rica, where there is no dry season it flowers later, between March and July. As the species is dioecious, the trees are either male or female and only produce male or female flowers. The small yellow flowers are thought to be pollinated by insects, the resulting fruits are dispersed by animals including monkeys, birds and fruit-eating bats and the seeds are also dispersed by leaf cutter ants.

In phylogenetic nomenclature, the Pentapetalae are a large group of eudicots that were informally referred to as the "core eudicots" in some papers on angiosperm phylogenetics. They comprise an extremely large and diverse group that accounting about 65% of the species richness of the angiosperms, with wide variability in habit, morphology, chemistry, geographic distribution, and other attributes. Classical systematics, based solely on morphological information, was not able to recognize this group. In fact, the circumscription of the Pentapetalae as a clade is based on strong evidence obtained from DNA molecular analysis data.
