Aspidistra Ker‐Gawl (Asparagaceae) is currently one of the fastest growing genera in Angiosperms. The literature is widespread in a great number of journals. In a number of cases species limits are more or less blurred, and especially the number and ranking of infraspecific entities are confusing. The paper provides a critical overview of all currently accepted infraspecific taxa in 11 species. Three...
Cross sections of petioles in 35 species of Astragalus mainly belonging to sect. Rhacophorus were studied for circumscription of natural groups within the section and reliable characters in delimiting polymorphic species. The following characters were determined to be informative: number of parenchymatous cell layers in pith, diameter of median sclerenchymatous vascular bundle sheath and diameter...
Iridaceae is a family of worldwide distribution and great morphological diversity. Differing from most monocot families, even the seedlings are remarkably diverse. The morphological analysis of seedlings of 36 genera revealed a good accordance of seedling types with recent molecular classifications of the family. Generally, the tribes as recently defined are homogeneous in their seedling structure...
