Description
Vegetative characteristics
Spathiphyllum silvicola is a perennial herbaceous plant with short, creeping rhizome. It leads no milk juice. The two lines on the rhizome standing leaves are stalked 13-76 cm long. The petiole is formed down to about 1/3 to 3/5 of its length, as a sheath and has at its upper end, a 1-2 cm long thickening ( geniculum ), which serves as the joint, if necessary. The simple and undivided, ganzrandigen leaf blades are narrow elliptic to lanceolate, rounded or rarely thickness taper at the base and pointed forward. They are 15 to 38.5 cm long and 4.5 to 11.5 ( -15.3 ) cm wide. You own both sides of each (9 - ) 12-23 lateral nerves of the first order, the reach with their bent toward the blade tip ends of the Spreitenrand, and parallel to other intervening weaker nerves. The lateral veins forming an angle of about 60-70 degrees in the center of the page with the midrib.
Generative features
The individually standing, bulbous stalked inflorescence is about 35-96 cm long. The wide-open spathe is the heyday light green or white with green veins and remains even after flowering. She is about 7.9 to 15 cm long and 1.7 to 4.3 cm wide and has a lanceolate or narrowly elliptic to ovate - lanceolate shape. The spathe is running 0.4-1.4 cm wide at the peduncle down and forward acuminate, with later something back curved tip. The white, later yellowish or green expectant, uniformly occupied with hermaphrodite flowers spadix is approximately 3.6 to 7.3 cm long, has about 4-8 mm in diameter and is stalked in the spathe 0.4-1.6 cm long.
The usually six tepals are fused in their lower half together, free at the top. There are usually six free stamens with short stamens present. The inverted pyramidal, truncated above stamp is about as long as the perianth. Only the three-lobed stigma projects beyond the perianth slightly. In the Upper constant, usually dreifächerigen ovary sit in each subject 2-3, total 6-7 ovules at the central angle constant placenta. The fruits are berries that are white when ripe and have a yellow tip.
The plants can bloom almost all year round. Only in the months of March and April, no flowering individuals have been observed so far.
Distribution and habitat
The species was endemic to 2003 as the Pacific side of Costa Rica, is now but also from Panama and the West of Colombia demonstrated.
It grows mainly in tropical lowland rain forests, from sea level up to about 500 ( -950 ) m altitude.
Taxonomy
Spathiphyllum silvicola was described in 1976 by Richard A. Baker, on the basis of collections made by the U.S. botanist Paul Allen Hamilton. The type locality is located in the canton of Osa in the province of Puntarenas in the south of Costa Rica. Up to the first description of this type plants have been mainly considered as Spathiphyllum fulvovirens, an also in Costa Rica, however, occurring only on the Caribbean side manner that differs among other things, larger leaves and spadix. Both types are found within the genus Spathiphyllum to section Amomophyllum. In habitat is also very similar to the more widely used Spathiphyllum laeve, which is not used as a member of the Section Massowia close and differs by the deformed to an undivided, ganzrandigen cup perianth.
Etymology
The specific epithet silvicola is composed of Latin silva (forest ) and lat - cola ( dwellers ) and thus means forest dwellers. It refers to the presence of the species in the interior ( forest shade ) of tropical forests. The word is a noun and therefore does not need to be adapted to the generic name with its extension. The genus name Spathiphyllum consists of spathe, the name for the conspicuous bract, which accompanies the inflorescence of Arum, and the ancient Greek word φύλλον together ( phyllon, dt Journal). The name refers to the fact that in this genus the spathe less different from foliage leaves, as is usual with the arum family.
