Magnolia poasana (known locally as the candelilla, or by the common name Poas magnolia) is a sub-tropical to tropical, subcanopy tree, growing in areas of montane rainforest. The names "Poas", and "poasana" originate from the Poás Volcano in Costa Rica where, along with Panama, they grow in the wild.[4] First described by Henri François Pittier in 1910 (treated in the genus Talauma), it was later described and included in Magnolia by James Edgar Dandy (1927).[2][3]
Magnolia poasana is between 10 and 30m in height, with a dbh of about 90 cm, and its growth habit is round and densely compact. It tends to be low branching, or tending to branch off from the base when in more open areas with greater sun exposure.[4]
The glossy, glabrous leaves are 12 x 5 cm in length, simple, alternate, elliptic, entire, apiculate, acute and lanceolate with prominent stipules, a scar encircling each leaf's petiole. The bark is smooth, reddish brown with a gray cast.[4]
Flowers bloom from the months of November through July, peaking in February, March and April. They are bisexual, 10 cm in diameter, with 6 spatulate, white petals and 3 gray membranous sepals. A perianth is formed of a yellowish white corolla.[4]
The tree bears its fruit, which are aromatic, cone-like, aggregate infructescenses, about 4 cm in length, in July and August. There are approximately 25 fruits of dehiscing capsules per infructescense. The fruit's seeds are exserted, and covered with bright networks of arils which dangle from threads. Seed germination is epigean.[4]
Mostly located in foothills of the Cordillera de Talamanca and Central, M. poasana has been documented as growing naturally as low as 500m, and as high as 2400m, but most trees have been found at elevations between 1300m to 2200m.[4][5] All specimens of M. poasana prior to 1972 were collected from Costa Rica, but since then samples have been collected in Chiapas, Mexico; in 1982 samples were also collected in Panama.[5] M. poasana is most often found growing in soils of alluvial or volcanic origin, in climates in which the temperature ranges between 4 and 25 degrees C; where the precipitation accumulates at rates of 2,000 to 3,000 mm per annum.[4]
The Poas magnolia has applications in construction and carving.
The wood is colored greenish-grey with an oven-dry specific weight of 0.38.[6] It has fine texture and an attractive finish, is easy to work and turn, yet durable. It is used in general construction and as a component in plywood; to decorate interiors as panelling, veneers and finishing; in cabinetry and the manufacture of furniture.[4]

Magnolia poasana est une espèce d'arbres de la famille des Magnoliacées présente au Costa Rica et au Panama.
Magnolia poasana est appelé en espagnol candilillo ou simplement magnolia au Costa Rica[2],[3].En français il est appelé magnolia de Poas[3]. En anglais il est appelé Poas magnolia[3].
Arbre moyen au feuillage persistant pouvant atteindre 20 m. Les feuilles simples, de formes elliptiques à oblongues, mesurent entre 10 et 20 cm. Leur marge est entière. Le sommet du limbe est acuminé alors que la base est arrondie ou cunéiforme. Le pétiole mesure entre 2,5 et 5 cm[2]. Le dessus des feuilles est coriace et glabre tandis que le dessous est presque glauque. Les fleurs crème hermaphrodites actinomorphes. Le périanthe est composé de neuf tépales obovaux. Les trois tépales externes qui sont sépaloïdes verdâtres à l'extérieur et blanc vers l'intérieur mesurent environ 5 cm[2].
Présente sur les contreforts de la cordillère de Talamanca et la cordillère Centrale, M. poasana pousse généralement entre 1 800 et 2 550 m[2]. On la trouve depuis la province d'Alajuela au Nord jusqu'à celle de Cartago et celle de San José (particulièrement présente sur les volcans de Poás et Barva)[2]. M. poasana se trouve plus souvent sur des sols d'origine alluviale ou volcanique, dans des climats où la température est comprise entre 4 et 25 °C; où les précipitations sont comprises entre 2000 et 3000 mm par an[4].
