ANALISIS TAKSOMETRI Anthurium SCHOTT (ARACEAE)

Pollination of Anthurium (Araceae) by derelomine flower weevils (Coleoptera: Curculionidae).

Cyclanthura flower weevils (Coleoptera: Curculionidae: Derelomini) are identified for the first time as pollinators of multiple species of Anthurium (Araceae) in Costa Rica. The weevils are present on the inflorescences in small numbers during the pistillate and staminate phase of anthesis, and consume plant tissues and pollen. The individuals of one species of Cyclanthura can visit several Ant...

A reassessment of Anthurium species with palmately divided leaves, and a reinterpretation of Anthurium section Dactylophyllium (Araceae)

A reappraisal is made of the Anthurium Schott species with palmately divided leaves with 3 or more segments free to the base (i.e. palmatisect leaves), previously recognized as section Dactylophyllium Schott (Engler), as well as those species with 5 or more segments united at the base (i.e. palmatifid leaves), formerly placed in section Schizoplacium Schott (Engler). New molecular data indicate...

Floral vasculature and its variation for carpellary supply in Anthurium (Araceae, Alismatales)

INTRODUCTION AND AIMS Anthurium is the largest genus of Araceae, with 950 species distributed in the neotropics. Despite the great diversity of the genus, the knowledge of its floral vasculature is based on observations in only two species, viz. A. denudatum and A. lhotzkyanum, with remarkable variation in vascular carpellary supply: carpels are either vascularized by ventral bundles alone or b...

Differentiated Microelement Content in Anthurium (anthurium Cultorum Birdsey) Leaves*

The main objective of the study was to determine the nutritional status in terms of the content of microelements, such as iron, manganese, zinc, copper and boron in several standard cultivars of anthurium (Anthurium cultorum Birdsey) called Baron, Choco, Midori, Pistache, President and Tropical. The plants were grown in expanded clay (ř 8-18 mm) using drip fertigation with standard nutrient for...
