description

Habit, reinforced leaves and infructescence of Araeococcus flagellifolius

Detail of an inflorescence with a threefold flower from Araeococcus parviflorus

The Araeococcus species grow as perennial herbaceous plants . They can grow epiphytically , lithophytically or, less often, terrestrially. They are relatively small species with small funnel diameters and inflorescences that are up to 1 m long. They form small stocks through Kindel or grow turf-shaped through runners ( Araeococcus flagellifolius ). The alternate leaves , arranged in a basal rosette, form slender, higher than wide leaf funnels, which in Araeococcus flagellifolius look almost rush-like . The sturdy leaf blades are wide, up to whip-like in Araeococcus flagellifolius ( specific epithet flagellifolius for whip-like leaf) and end in a spike tip. The leaf margins are smooth or serrated, spiky reinforced. The leaf surfaces are covered with suction scales.

An upright or overhanging Blütenstandsschäften are branched, double or multiple traubige inflorescences (inflorescences) where many flowers are arranged mostly loose. Sit at the inflorescences relatively inconspicuous bracts (bracts).

The stalked, relatively inconspicuous, hermaphrodite flowers are radial symmetry and threefold with a double flower envelope (perianth). There are three sepals . The three free petals are green or purple. There are two circles with three stamens each. Three carpels are under constant ovary grown.

The flower formula is: ${\ displaystyle \ star \; K_ {3} \; C_ {3} \; A_ {3 + 3} \; G _ {\ overline {(3)}}}$

Low-juice berries are produced.

Systematics and distribution

Adolphe Brongniart introduced the genus Araeococcus in 1841 with the type species Araeococcus micranthus Brongn. in Annales des Sciences Naturelles; Botanique , Ser. 2, 15, p. 370. The genus name Araeococcus is derived from the Greek word araios for thin and the Latin word coccum for berry.

The neotropical distribution area of the genus Araeococcus ranges from Costa Rica to Venezuela , Colombia , Bolivia and Brazil , as well as Trinidad and Tobago .

There are about nine Araeococcus species (as of 2014):

Araeococcus chlorocarpus (Wawra) Leme & JASiqueira : It occurs in the Brazilian states of Pernambuco , Bahia and Alagoas .
Araeococcus flagellifolius Harms : It thrives epiphytically on trees and rocks in the rainforest and in the savannah at altitudes of 150 to 240 meters in the catchment area of the Orinoco and the Amazon in Colombia , Venezuela , Suriname and Brazil.
Araeococcus goeldianus L.B.Sm. : It thrives epiphytically on trees and rocks at altitudes of 10 to 80 meters only in the Brazilian state of Amapá .
Araeococcus micranthus Brongn. : It iswidespreadin Venezuela, Brazil, Guyana and on the islands of Trinidad and Tobago. It rarely thrives terrestrially, mostly epiphytic in different forest types at altitudes of 80 to 470 meters.
Araeococcus montanus Leme : It only thrives epiphytically in the Brazilian state of Bahia.
Araeococcus nigropurpureus Leme & JASiqueira : It was first described in 2007 from the Brazilian state of Bahia. It thrives epiphytically at altitudes of about 130 meters.
Araeococcus parviflorus (Mart. Ex Schultes & Schultes f.) Lindman:: It thrives terrestrially or epiphytically in forests at altitudes of 30 to 100 meters only in the Brazilian state of Bahia.
Araeococcus pectinatus L.B.Sm. : It thrives epiphytically in rainforests at altitudes of 30 to 540 meters in Costa Rica and Colombia.
Araeococcus sessiliflorus Leme & JASiqueira : It was first described in 2007 from the Brazilian state of Bahia. It thrives epiphytically in the damp Mata Atlântica at altitudes of 50 to 650 meters.
