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...

Significant progress has been made in understanding biological invasions recently, and one of the key findings is that the determinants of naturalization and invasion success vary from group to group. Here, we explore this variation for one of the largest plant families in the world, the Araceae. This group provides an excellent opportunity for identifying determinants of invasiveness in herbac...

BACKGROUND AND AIMS For 84 years, botanists have relied on calculating the highest common factor for series of haploid chromosome numbers to arrive at a so-called basic number, x. This was done without consistent (reproducible) reference to species relationships and frequencies of different numbers in a clade. Likelihood models that treat polyploidy, chromosome fusion and fission as events with...

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...

A new species of Stenospermation (Araceae), S. coques sp. nov., endemic to the Isla del Coco National Park in Costa Rica is described and illustrated. discussion about morphologically related their differences also included.

Arisaema speciosum is a wild lily of family Araceae. This paper reports anti-inflammatory properties of the ethanolic extract of the corm of Arisaema speciosum .The ethanolic extract of corm of Arisaema speciosum showed in vitro cytotoxic effect against Ehrlich ascitic cells. When the extract was injected in tumour bearing mice, tumour disappeared in 40% animals. Injection of ethanolic extract ...
