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.
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 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.
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.
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.
The name is composed of parts of the names of three of the most popular genera. ALoe gaSTERia haWORTHIA = Alsterworthia. International signifies the international nature of the journal.
To promote and facilitate the distribution of colour-illustrated information, primarily for haworthias, gasterias and aloes, but also occasionally for related genera (Asphodelaceae family), including hybrids and cultivars, without favour by:
- Publishing the journal Alsterworthia International, ISSN 1474-4635, in March, July and November each year. Available only to members.
- Publishing occasional Special Issues on specific subjects, including reprints of not-so-readily-available scientific papers. Available to the public direct or through booksellers. Discount for members only from Alsterworthia International.
- Making relevant books and the Japanese Society journal "Haworthia Study" available to the public and members. Discounts for members only on some books and Haworthia Study.
Alsterworthia International has 12 representatives in eleven countries. Jakub Jilemicky, is representative for Czech Republic and Slovakia. If you have questions or want to receive this journal, don´t hesitate to ask me or directly Harry Mays.
A seed list is normally distributed with the March journal each year. The number of species may vary from year to year but the list will include approximately 150 Aloe, 40 Haworthia, 20 Gasteria and some Asphodelus, Astroloba and Bulbine species.
Members who supply e-mail addresses will receive the annual seed list by file attached to e-mail as soon as it is available, usually several weeks before the March journal is available.Alsterworthia International Special Issues
The subject matter of Special Issues is broadly similar to that of the journals, but articles are generally more extensive. Special Issues are also better suited to reprints of scientific papers, which are not-so-readily-available to the public. Some important articles published in parts in different journals are also published together as special issues for non-members.
Special issues may be ordered from the editor or from booksellers by title and ISBN number. Alsterworthia members receive a discount on special issues when ordering from Alsterworthia International only. Members' discounts are published each year in the November journal.
