Cytological Studies in Diploid and Triploid <i>Hosta</i>

A Karyosystematic Study of the Genus Agave

“…In the work of Taylor (1925) and Morinaga et al (1929) on Yucca filamentosa; Imai and Kanna (1934), Akemine ( 1935) and Yasui (1935) on Hosta; Matsuura and Suto (1935) on Hosia and Yucca; Sato (1935), Doughty (1936) and Vignoli (1936Vignoli ( , 1937 on Agave, relative size differences were brought out and terminal spindle fiber attachments indicated in the large chromosomes.

“…The common occurrence of vegetative reproduction by suckers and bulbils makes autopolyploidy by means of somatic doubling quite probable.

A Karyosystematic Study of the Genus Agave

“…From about 1925 on, workers paid more attention to chromosome morphology and to the phylogenetic relationships that might be indicated from karyotype similarities. In the work of Taylor (1925) and Morinaga et al (1929) on Yucca filamentosa; Imai and Kanna (1934), Akemine ( 1935) and Yasui (1935) on Hosta; Matsuura and Suto (1935) on Hosia and Yucca;Sato (1935), Doughty (1936) and Vignoli (1936Vignoli ( , 1937 on Agave, relative size differences were brought out and terminal spindle fiber attachments indicated in the large chromosomes.…”

Karyotype Alteration and Phylogeny. IV

“…Again the haploid num ber of Hosta has been stated from the time of Strasburger until quite recently to be 24 instead of 30 (cf. Whitaker 1934, Sato 1935b, Ake mine 1935, Yasui 1935, Matsuura and Suto 1935. McKelvey and Sax (1933) have called attention to the existence of taxonomic and cytological similarities of the genera Yucca ,*…”
