Microsporogenesis and pollen sulcus type in Asparagales (Lilianae)
Canadian Journal of Botany, 1997Cladistic analysis of molecular data (plastid rbcL sequences) supports the interpretation of simultaneous microsporogenesis as an apomorphy for Asparagales (Lilianae), with a reversal in the most derived 'higher' asparagoid clade, which is entirely successive.

Sansevieria pfennigii (Ruscaceae, Asparagales)
2021Sansevieria pfennigii, which to date has been a doubtful species, is confirmed as extant by a recent collection from the Lindi Region in southern Tanzania. The original description of the species, which is based on herbarium material only, is here emended based on additional observations recorded from living plants, including fruits that were ...

Two New Monocotyledon Families: Anemarrhenaceae and Behniaceae (Lilianae: Asparagales)
Kew Bulletin, 1997Summary. Two new monocotyledon families Anemarrhenaceae and Behniaceae are described for the monotypic but somewhat isolated genera Anemarrhena and Behnia. The differences from previous morphology-based associations near Anthericaceae and Luzuriagaceae respectively are considered, and their current relationships based in part on molecular sequence data

Miocene Astelia (Asparagales: Asteliaceae) macrofossils from southern New Zealand
Australian Systematic Botany, 2011The discovery of Early Miocene Asteliaceae fossils at Foulden Maar in southern New Zealand provided a good opportunity to assess the usefulness of cuticular information for identifying members in this family. On the basis of cuticular morphology, the Foulden specimens are assigned to Astelia Banks & Sol. ex R.Br.

Flower Anatomy and Systematics of Comospermum (Asparagales)
Systematics and Geography of Plants, 1999Flower anatomy and ovule development is described in Comospermum yedoense and Eriospermum natalense. A close relationship between Comospermum and Eriospermum, earlier indicated by rbcL, now seems doubtful, as their seed hair types are not homologous and they differ in other respects.

Two new species of Clinanthus (Asparagales: Amaryllidaceae: Clinantheae) from northern Peru
Phytotaxa, 2020Clinanthus fabianae and C. thiagoi are described from Ancash and La Libertad departments of Peru. Both species have similar perigone coloration, broadly lobed staminal coronas, and incurved free filaments. They may represent a distinct species group, along with the previously described C. inflatus.

RNA editing has been lost in the mitochondrial cox3 and rps13 mRNAs in Asparagales
Biochimie, 2007RNA editing in plant mitochondria alters the RNA sequence by converting C-to-U or U-to-C at a specific site. We investigated the requirement for RNA editing in the complete genomic sequences of the gene encoding the cytochrome oxidase subunit III (cox3) and the ribosomal protein S13 (rps13) in 59 closely related species within the Asparagales and ...

A karyological review of the orders Asparagales and Liliales (Monocotyledonae)
Feddes Repertorium, 1995AbstractKaryology 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 withx= 10, and Tecophilaeaceae, Cyanastraceae, and Ixioliriaceae withx= 12.Tricyrtis(Uvulariaceae) is karyologically similar ...
