| Alstroemeria L. (Alstroemeriaceae) is an American genus of monocots with two principal distribution centers in Chile and Brazil. In Chile, it is represented by about 32 species, most of them in central Chile, an area known for its high level of endemism. The "complex" Alstroemeria hookeri is endemic to Chile, where it is distributed from the Coquimbo to the Bío-Bío Region. We analyzed the karyotypes of 36 populations of this complex along its natural distribution. Ten metaphases per population were used for chromosome measurements. All analyzed subspecies presented a well defined asymmetric karyotype. The populations of A. hookeri subsp. hookeri collected in the coastal range of the Bío-Bío Region and the populations from the Central Valley of this Region... |

| Magnolia section Maingola Dandy is distinguished from other members of Magnoliaceae by the combination of a terminal brachyblast, cylindrical fruits, and free stipules. Morphological characters were re-examined for section Maingola and section Alcimandra, which has been considered to be closely related to the former. Although section Alcimandra is separated from section Maingola in having long stamens which hide the gynoecium, it is combined with section Maingola because this feature is frequently found in various other taxa of the family. Moreover, recent molecular phylogenetic studies have also demonstrated the close affinity between sections Maingola and Alcimandra. For the Magnolia macklottii complex, which has been problematic due to the wide range of... |
