AROMA

A geo-historical perspective on the distribution and variation in , s.l. (,) in Mexico and C. Ameriesults from a fortuitous combination of a pliable and open breeding system, rapid and recent fluctuations in local climates, and the influence of mankind in creating the disturbed habitats favored by many senecios.

A preliminary cladistic analysis of the genus ,), analyses support the overall synoptic treatment of . and ., however there are areas of phylogenetic and taxonomic difficulty which need further study. Other non-morphological characters are required to resolve problematic relationships and provide a taxonomic framework reflective of phylogenetic relationships.

Introduction,on July 26, 1987, was designed to complement the University of Reading . Conference (1975). The latter had yielded two impressive and thorough volumes on “The biology and chemistry of the .”, which were edited by Heywood, . (1977). The 1987 Berlin Symposium did not attempt to update the information

Progress in the chemistry of the ,),henyl propanes and p-hydroxyacetophenone derivatives. However, some groups of genera or species differ from this general picture. Glaucolides are absent, with two exceptions, from species of the subtribes . and ., but common in the ., especially in the large genus ., but also in the subtribes . and

名词

A preliminary cladistic analysis of the genus ,), World taxa are largely distinct, but differences in topology of equally parsimonious trees indicate that the level and position of connections is unclear. The yellow-flowered trinervate-leaved species of Madagascar separate out as distinct from other Old World taxa as do the large-headed leafy-brac

Pert敏捷

Isolating mechanisms and implications for modes of speciation in ,),mechanisms between and among closely related species has been undertaken using available monographs. The predominant isolating factor is reproductive isolation, with many closely related taxa differing in chromosome number or being incompatible. Geographical isolation was found in 67% of the groups.

In Ouchterlony immunodiffusion assays the reactivities of the sera were tested using 22 cynarean species. The results strongly suggest that the traditional “.” concept may not reflect phylogenetic relationships and support separate tribal ra
