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]
Leaves and bark
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
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]
