These paper deals with 45 taxa, seven of which are new to the Balearic Islands flora: Agrostis capillaris L., Centaurea solstitialis L. Chenopodium strictum Roth, Datura wrigthii Regel, Kickxia elatine (L.) Dumort. subsp. elatine, Ranunculus xatardii Lapeyr. and Senecio inaequidens DC. On the other hand, six taxa [Catananche caerulea L., Centaurea apula Lam., Filago micropodioides Lange, Legous...

Two new benzophenones, methyl (R)-3-[2-(3,4-dihydroxybenzoyl)-4,5-dihydroxyphenyl]-2-hydroxypropanoate (1) and n-butyl (R)-3-[2-(3,4-dihydroxybenzoyl)-4,5-dihydroxyphenyl]-2-hydroxypropanoate (2), were isolated from the roots of Ranunculus ternatus along with the two known compounds vanillic acid (3) and gallic acid (4). Their structures were elucidated by physical and spectroscopic analysis. I...

In a project on the Flora of Iran (Trib.: Ranunculeae), many herbarium specimens of thegenus Ranunculus were studied. The results of this study are a new record and suggestion of a synonym for the Flora of Iran, specimens of which are preserved in the herbarium of Research Institute of Forest & Rangelands (TARI). 

The taxonomic affinity of six species of Crocus (C, cancellatus subsp. Damascenus C. almehensis, C. gilanicus, C. sativus, C.pallassi subsp. haussknechtii,C. speciosus subsp. speciosus) from Iran were studied usingdifferent electrophoresis techniques. The similarity index of the species was computed by comparison of protein bands of - Corm and seed tissues, and the related dendrogms of affi...

Genome evolution in asexual organisms is theoretically expected to be shaped by various factors: first, hybrid origin, and polyploidy confer a genomic constitution of highly heterozygous genotypes with multiple copies of genes; second, asexuality confers a lack of recombination and variation in populations, which reduces the efficiency of selection against deleterious mutations; hence, the accu...
