New information about ontogenesis and ontogenetic structure of cenotic populations the rarest endemic Kyzylkum mountains Eremurus anisopterus (Kar. & Kir.) Regel is presented. Plant communities with participation cenopopulations studied species are characterized. Duration in natural conditions lasts more than 20 years. The vegetation cycle E. under desert five months, from March to July. st...

Three species of Eremurus M. Bieb. grown at UASVM Iasi, Romania, were studied: E. himalaicus Baker, robustus Regel and stenophyllus (BOISS. & BUHSE) Bak. Some ornamental (morphologic phenologic) features analyzed also the anatomic structure leaf, content photosynthetic pigments enzymatic activity leaves. The biometrical phenological determinations indicate a good ecological adaptability pla...

Two-year study on the pollination ecology of Eremurus inderiensis reveals that the florescence of eremurus is from the middle ten days of May to the first ten years of June, anthesis of a single flower lasts one day. When the weather is rainy and the highest temperature is less than 20 centigrade, anthesis of a single flower can last two days. Pollen dispersal period of single flower can last f...

Two new species of Psychodinae, Psychodidae, from the semi-arid region of Brazil are described and illustrated: Arisemus rubeni sp. nov. and Lepidiella olgae sp. nov. Only nine psychodid species were previously known from that region.

Incarvillea is a herbaceous and temperate member of Bignoniaceae, previously divided into four subgenera, Niedzwedzkia, Amphicome, Incarvillea, and Pteroscleris. Niedzwedzkia and Amphicome have in the past been treated as independent genera. Different relationships have been proposed for the four subgenera. Here, maximum parsimony analysis using ITS and trnL-F sequences resulted in similar tree...
