Validation of the Name Anthurium nutibarense (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...

construction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers

the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
