Ecological and botanical characteristics of plant of the genera Heuchera L. species

Abstract

The article considers the environmental confinement of the genera Heuchera L. species. It was presented botanical characteristics and detailed description of morphological characters of vegetative and generative sphere of plants of Heuchera species from the collection fund of M.M. Gryshko National Botanical Garden of the NAS of Ukraine. It was found that in conditions of introduction plant of ge nera Heuchera species form a system of half-way female, polycarpic, vegetative and generative, orthotropic, polycyclic, monopodially interconnected shoots. Heuchera species can be distinguished by the shape of the fruit, the size of the box, the depth of the constriction around the receptacle, the degree of submergence boxes in a cup. These differences can be used as supplementary diagnostic criteria. It was detected morphological differences in the form of seed (broad (H. chlorantha), rounded narrowl oval (H. cylindrica), narrowly oval (H. grossulariifolia), narrowly lanceolate (H. villosa)), which have diagnostic value at the species level.
