“…The ITS1 sequence data provide additional evidence that Hosta is related to Agavaceae sensu stricto, congruent with the karyotypes, immunological studies (Chupov and Kutiavina, 1981b), and cpDNA evidence (Bogler and Simpson, 1995). For many years Hosta was associated with Hemerocallis, Hesperocallis, and Leucocrinum (Krause, 1930;Hutchinson, 1934 (Cave, 1948(Cave, , 1970.…”

“…in size, with three large chromosomes and 12 smaller ones (Sato, 1935;Fernandez and Davifia, 1991). Some species of Chlorogalum also have n = 15 chromosomes that are very similar to Camassia, but a few species of Chlorogalum have n = 30 chromosomes, with five large chromosomes as in Agavaceae (Cave, 1970;Sen, 1975). It is possible then, that the n = 30 bimodal karyotype of Agavaceae originated with a doubling of the chromosomes in a common ancestor closely related to Camassia, Chlorogalum, and Schoenolirion.…”

A distinctive bimodal karyotype and similarities of fruits and seeds strongly support close relationships among Yucca, Hesperaloe, Beschorneria, Furcraea, Agave, Manfreda, Polianthes, Prochnyanthes, and perhaps Hosta. However, Dasylirion, Beaucarnea, Nolina, Calibanus, Dracaena, and Sansevieria differ in so many cytological and morphological features that many have concluded they should be excluded from Agavaceae and separated into two families, Nolinaceae and Dracaenaceae. Chloroplast DNA restriction site data support these separations and indicate that Nolinaceae and Dracaenaceae are very close to Convallariaceae (Maianthemum, Convallaria, Aspidistra, Liriope, etc.). In this paper we report the results of an ITS rDNA sequencing study of 40 taxa in Agavaceae sensu lato and related groups in the order Asparagales. Sequence alignments were optimized using the Consistency Index, Retention Index, and Rescaled Consistency Index to find the alignment that exhibited the least amount of homoplasy. The results of our study are congruent with the conclusions drawn from cytological, immunological, cpDNA, and rbcL studies, which support a narrow interpretation of Agavaceae and a close relationship among Convallariaceae, Dracaenaceae, and Nolinaceae. In addition, the ITS sequence data provide evidence for some interesting relationships within these families.

“…For Hastingsia, Cave (1970) found n = 26 (based on four counts), suggesting that the genus has a tetraploid cytotype with five or six large chromosomes. Similarly, Cave (1948) found n = 24 in Hesperocallis, with five large chromosomes, indicating a possible fusion or loss of small chromosomes.…”

“…Notably, all members of Chlorogaloideae have a bimodal karyotype, in which chromosomes fall into two distinct groups of sizes (Sato 1935;Gould 1942;Sherman 1969;Cave 1970;Fernandez and Daviñ a 1991). The discovery of this character first indicated a close relationship to members of Agavaceae, in which the presence of bimodal karyotypes has long been recognized (McKelvey and Sax 1933;Akemine 1935;Sato 1935;Watkins 1936;Granick 1944;Cave 1948Cave , 1970Sen 1975;Tamura 1995;Pires et al 2006;McKain et al 2012).…”

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.
