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...
متن کاملPollination 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...
متن کاملFloral 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...
متن کاملHardware Outline Character Rasterization
For several years, engineers and typographers have been working on a new generation of fonts. The old bitmap description of a character is giving way to characters defined by their outlines. This new description of a character makes a font independent of the size of the desired bitmap character. This in turn makes the font independent of the resolution of the hardware which will be used to rend...
متن کاملPlant Identification Based on Leaf Midrib Cross-Section Images Using Fractal Descriptors
The correct identification of plants is a common necessity not only to researchers but also to the lay public. Recently, computational methods have been employed to facilitate this task, however, there are few studies front of the wide diversity of plants occurring in the world. This study proposes to analyse images obtained from cross-sections of leaf midrib using fractal descriptors. These de...
