“…1 c). Later reports indicate that all varieties of L. tigrinum are allotriploids (9,10). A trivalent at diakinesis and metaphase I is the product of at least one partner switch and one cross-over in the paired segments on each side of the switch.…”

On the basis of cytological data and with consideration of a wide literature, the taxonomy of Liliales as delimited by Hutchinson are represented. A review about phylogeny of Liliaceae in different systems is given. In the main part a great number of tribes of Liliaceae are treated with regard to delimitation, affinities and evolution. Further a cytological assessement of evolution and interrelationships of different families of Liliales with Liliaceae were indicated. Ultimately the lines of evolution of Liliaceae were debated. Especially e. g. the following more important conclusions were outlined: The primitive tribe Heloniadeae might have descended from Juncaginaceae. The potentiality of Asphodeleae as the progenitor of different tribes of Liliacae has been confirmed. The tribe Ophiopogoneae is quite homogeneous, whereas the tribe Hemerocalleae has been indicated as an unnatural group, and some genera are transfered under Agavales. The origin of Amaryllidaceae from Tulipeae and Hemerocallideae is confirmed. Agapantheae is an advanced representative of the subfamily Allioideae of Amaryllidaceae. In Polygonatum the “latifolium” type of “alternifolia” represents the primitive state with 9 or 10 as basic chromosome number. The midtertiary origin of Smilacina has been supported. Disporum of pleistocene origin is likely to have given rise to Polygonatum through diminution in chromosome size and asymmetry on the one hand and Smilacina on the other, with increase in asymmetry. Asiatic species of Disporum representing the most primitive form and have been reponsible for the evolution of the American species of Disporum and in another line of Aspidistreae, Convallarieae, and Peliosantheae. The creation of the tribes Dianelleae and Veratreae is supported. With the exclusion of Calochortus and Lloydia, Tulipeae would represent a homogeneous grouping. In Scilleae, Scilla sibirica with n = 6 chromosomes represents a primitive form. Muscari is to be separated into three genera. The Tulipeae should be divided into several assemblages which represents origin from a common stock.
