(botany)
The laurel family of the order Magnoliales distinguished by definite stamens in series of three, a single pistil, and the lack of petals.

Lauraceae

 

a family of dicotyledonous plants. They are trees and shrubs and, rarely, parasitic herbs. The simple leaves are generally leathery and persistent; as a rule, they are alternate and exstipulate. The flowers are three-parted (more rarely five-or two-parted), bisexual (sometimes unisexual), regular, small, and racemose. The ovary is superior; very rarely is it inferior. The fruit is a monospermous berry or drupe and is often surrounded by a fleshy floral tubule. The leaves, bark, and other parts of many plants of this family have glands that contain essential oils.

There are 40 to 50 genera (over 2,000 species) of Lauraceae, distributed predominantly in the tropics; they are less frequently encountered in the subtropics. Only a few genera are found in temperate regions, where they had been widely distributed in the Tertiary period. The Lauraceae include the genera Cinnamomum (including the camphor tree), Laurus, and Sassafras, as well as other useful plants. Many species of Lauraceae yield spices (bay leaves and cinnamon), edible fruits (avocado), camphor, essential oils, medicinal substances, wood for construction and the manufacture of small articles, and other valuable products.

Lo anterior es evidencia de la heterogeneidad de los remanentes de bosque de la planicie payanesa y la accion antropica que ademas genera restriccion a la dispersion y establecimiento de muchas especies como se refleja en la poca representatividad de especies de las familias Lauraceae y Ericaceae, que son una fuente importante de alimento para la fauna silvestre (Pincheira et al.
El primer grupo es de especies tolerantes a la luz pertenecientes a familias como Annonaceae, Burseraceae, Clusiaceae, Melastomataceae, Meliaceae, Ochnaceae, Rubiaceae, Simaroubaceae y Vochysiaceae; y las especies tolerantes a la sombra de familias como: Caesalpiniaceae, Chrysobalanaceae, Apocynaceae, Euphorbiaceae, Humiriaceae, Lauraceae, Lecythidaceae, Linaceae, Mimosaceae, Moraceae, Myristicaceae, Myrsinaceae, Papilionaeae, Sapotaceae y Sterculiaceae (MARTINEZ-HIGUERA, 2006 El TFP mas importante para la evaluacion de la resiliencia fue el TFP1 por contener especies del grupo ecologico de las esciofitas con frutos y semillas grandes y de gran peso, dispersadas por gravedad y animales, lo que indica un alto grado de conservacion; este grupo funcional es representativo en Don Sixto.

As an example, plants belonging to the families Amaryllidaceae, Apocynaceae, Araceae, Asteraceae, Bixaceae, Clusiaceae, Dilleniaceae, Lamiaceae, Lauraceae, Lygodiaceae, Myrtaceae, and Santalaceae were used only in Dinajpur district but not in the other three districts surveyed.
pertence a familia Lauraceae, genero Persea, o qual compreende tres variedades botanicas, em uma unica especie: Persea americana var.
The objectives of this study were to: 1) determine if volatile monoterpenes, produced by redbay and other trees in Lauraceae attract Xyleborus glabratus and 2) determine the seasonal activity of Xyleborus glabratus.
De acordo com levantamento florístico prévio, as famílias mais freqüentes na área são as Myrtaceae, Mimosaceae, Lauraceae e Rubiaceae (Campos e Souza, 1997; Souza et al.
As familias com maior presenca na Floresta Ombrofila Densa Sub Montana foram Caesalpiniaceae, Moraceae, Myristicaceae, Annonaceae, Lauraceae, Melastomataceae, Lecythidaceae, Sapotaceae, Clusiaceae, Flacourtiaceae e Mimosaceae, determinando estas 11 familias a composicao floristica deste ambiente, com pouco mais do que 50% do total da composicao floristica.
Todos os fragmentos analisados foram identificados como pertencendo ao genero Ocotea, da familia Lauraceae, plantas vernaculamente conhecidas como canela.
