Visitors get to see what the wildling looks like, a tall, leggy bush with bract clusters isolated at the end of long branches.
In turn, 21 descriptors were applied to determine the qualitative features: plant habit; leaf variegation, leaf variegation distribution, main color of the sheet on the upper face, leaf anthocyanin pigmentation, spinescence, color of spines, wavy-edged blades, shape of the peduncle, external color of the shell syncarp, syncarp shape, bract apex shape of the fruitlet, overlapping bracts in relation to the fruitlet, bract color of the fruitlet, bracts at the base of the crown, bract color at the base in relation to the crown, bract color of the crown, crown length/syncarp length ratio, crown diameter/syncarp diameter ratio, number of colors of the crown and the shape of the crown apex.
The genus is characterized by the following traits: stem hemiparasites rarely with long epicortical roots; bisexual flowers ultimately arranged in dichasia, often with the central flower aborted, and subtended by a main bract and two lateral bracteoles (Suaza-Gaviria et al.
The concentration of anthocyanin and chlorophyll were quantified during bract development in two selected cultivars (Red and Yellow).
Quantitative characters were: plant height (from the plant basis to top of primary head); plant diameter (one end to the other of the lower leaves); floral stem length (from the plant basis to the primary head insertion); floral stem diameter (10cm below the primary head insertion); number, length and width of the leaves; number of lateral buds formed after harvest; days of implementation to harvest; fresh mass, length and diameter of the primary head; external bract length; length, width and thickness of the bracts' edible portion (bract basis); thickness, fresh mass and diameter of the bottom; number of secondary heads per plant; bottom fresh mass/ primary head fresh mass ratio.
0 mm long; lowermost bracts oblong and obtuse, wider and shorter than the narrowly triangular and acute uppermost bracts; bract length sub-equaling pedicel length at the lower part of the racemes to sub-equaling or slightly exceeding calyx length at the apex of the inflorescences.
This section is quite well morphologically characterized and includes herbaceous species with terminal and axillary female inflorescences, axillary male inflorescences, and female bracts with long, linear-subulate teeth, usually more than 1/2 of the bract length.
