The journal - Alsterworthia International
- ISSN 1474-4635

The journal is published in March, July and November each year and printed on A4 gloss art paper (for comparison - one A4 page is the equivalent of two A5). The entire journal is devoted to plant articles, new publications, reviews etc and is liberally illustrated in colour.

Scope

Primarily the succulent genera of the Asphodelacea. The Asphodelacea family R.M.T. Dahlgren, H.F. Clifford and P.F. Yeo is defined in "The families of the Monocotyledons: Structure, Evolution and Taxonomy" published in 1985 by Springer-Verlag, Berlin. Circa 17 genera were included in the family, but, in subsequent years, some have been amalgamated with varying degrees of acceptance by botanical authorities.

The Asphodelaceae family is divided into two subfamilies, the Alooideae and the Asphodeloideae.

Subfamily Alooideae

The genera are Aloe, Astroloba, Chamaealoe, Gasteria, Haworthia, Lomatophyllum and Poelnitzia. They range in size from small, succulent-leaved rosettes (haworthias, some aloes and some gasterias etc) very suitable for glasshouse cultivation, to large shrubs/trees (some aloes, some gasterias) suitable for cultivation in gardens and larger glasshouses, though young plants can be kept in pots in a smaller glasshouse for many years before they out-grow their welcome. As these genera are highly succulent and popular with collectors, they are covered regularly in Alsterworthia International.

Subfamily Asphodeloideae

The genera include Asphodelus, Asphodeline, Bulbine, Bulbinella, Eremurus, Jodriella, Kniphofia, Simethis and Trachyandra. They are quite diverse in form ranging from succulent through mesomorphic to xeromorphic. They feature much less prominently in collections, but some, such as the "caudiciform" Bulbine, do have a following and a number of Kniphofia are popular and quite hardy garden plants. Occasional articles are devoted to the genera of this subfamily as the need and opportunity arises.

Subjects covered

Alsterworthia International is a journal comprehensive in scope. All relevant subjects are covered including habitat, laboratory and glasshouse studies; cultivation and propagation; taxonomy; pure species, hybrids and cultivars; pests and diseases; important information published in journals and books not readily available; history; personalities and more.
