“…Nevertheless, the chromosomes of C. indica and Indian Iphigenia species differ in their morphology. The chromosomes in I. indica , I. magnifica , I. mysorensis , I. pallida , and I. stellata were either metacentric or submetacentric (Rama et al, ). Metacentric chromosomes dominated the karyotype in I. indica , I. magnifica and I. stellata while I. mysorensis and I. pallida had predominance of submetacentric chromosomes.…”

The tribe Iphigenieae (Colchicaceace, Liliales) includes two genera, viz. Camptorrhiza and Iphigenia, which are distributed in Africa, India, and Australasia. Iphigenia is represented by 12 species, of which six occur in India while Camptorrhiza comprises one species each in Africa (C. strumosa) and India (C. indica). The genus Camptorrhiza possesses a knee‐shaped tuber attached to the corms, filaments with a thick bulge in the middle and styles with single stigma. Iphigenia on the other hand lacks knee‐shaped tuber, bears linear filaments and has styles with three stigmas. Camptorrhiza indica possesses ovoid corms, linear filaments and styles with a single stigma. These characters are intermediate between Iphigenia and Camptorrhiza and hence we studied the cytogenetics and phylogenetic placement of this species to ascertain its generic identity. Somatic chromosome count (2n = 22) and karyotypic features of C. indica are very similar to that of Iphigenia species. Molecular phylogenetic studies based on atpB‐rbcL, rps16, trnL, and trnL‐F regions showed that C. indica is nested within a lineage of Indian Iphigenia species. Thus, C. indica was reduced to a species of Iphigenia, i.e., I. ratnagirica. Camptorrhiza is now a monotypic genus restricted only to southern Africa. A key to the Indian Iphigenia species is provided. In addition, a new combination Wurmbea novae‐zelandiae is proposed for Iphigenia novae‐zelandiae.

Karyology of the Asparagales and Liliales is reviewed with references to their morphology, embryology, DNA analyses, and other aspects. Asparagaceae, Ruscaceae, Dracenaceae, and Nolinaceae may share a common ancestor with x = 10, and Tecophilaeaceae, Cyanastraceae, and Ixioliriaceae with x = 12. Tricyrtis (Uvulariaceae) is karyologically similar to Tulipa, Gagea (Liliaceae) and Smilax (Smilacaceae); Clintonia (Uvulariaceae) to Medeola (Liliaceae); Prosartes and Streptopus (Uvulariaceae) to Calochortus (Calochortaceae); Scoliopus (Trilliaceae) to the Medeola‐Clintonia group or Calochortus‐Prosartes‐Streptopus group. The original chromosome size of the Asparagales and Liliales may be estimated as small.
