description
Vegetative characteristics
In Alpinia luteocarpa is a perennial herbaceous plant , the stature heights of up to 1.5 meters reached. They form creeping rhizomes as persistence organs. The unbranched stems are smooth. Of the alternate, simple leaves that are all in one level, the largest have a length of up to 17 centimeters and a width of up to 5 centimeters. Most of the leaves remain smaller and are lanceolate with a pointed upper end. The top of the leaf is dark to olive green and the underside is red.
Generative characteristics
The terminal inflorescence contains three to five flowers. The bracts are brown to dark purple in color. The hermaphrodite flowers are zygomorphic and threefold. The red sepals are fused to more than half of their length. The white petals are fused tubular to about the middle. Only one of the six stamens is fertile . The other five have grown together to form a lip-shaped structure. Three carpels have become an ovary grown.
The fruits, which are yellow when ripe, have a diameter of about 3 centimeters, are round, three-way and contain numerous seeds. The brown seeds are about five millimeters long.
distribution
Alpinia luteocarpa was first described in 1939 from the island of Luzon in the Philippines . A finding is also available for Thailand.
Systematics
Adolph Daniel Edward Elmer wrote this species in 1939 in his first description in Leaflets of Philippine Botany , 10, pp. 3803-3805, without adding a diagnosis in Latin , as was still required in the nomenclature rules at that time . There is therefore some doubt as to whether the species name is taxonomically valid.
Alpinia luteocarpa belongs to the subgenus Dieramalpinia within the genus Alpinia according to the classical taxonomy . A phylogenomic study based on the comparison of homologous DNA sequences by Walter John Kress et al. 2005 resulted in a position in a species group ( clade V), which is closely related to the genera Etlingera , Hornstedtia and Amomum . The u. a. the necessary splitting of the genus into monophyletic units, which will lead to the renaming, has not yet been carried out. According to the analysis, the closest related species were Alpinia pinetorum and Alpinia elegans . In Chaveerach et al. In 2008 Alpinia luteocarpa is still mentioned as occurring in Thailand.
