LOSS OF TYPE SPECIMENS It is with regret that we have to report the loss of a large number of type specimens of Rubiaceae, Naucleeae that were being sent on loan. The boat, which was carrying the postal packages, sank in the Azores. As part of the routine work for the herbarium type specimen database the material had been processed beforehand and so digital images remain. Clearly some material is completely lost, particularly Blume and Korthals collections, isotypes will exist in many other cases, though the position 288 REINWARDTIA [VOL.12 for BW numbers is uncertain, generally distribution was Canberra, Lae, Arnold Arboretum. NHN Internet site for type specimens gives the type images and indicates that they are no longer extant in NHN herbarium. The taxa involved are indicated in the table below. The digital images have no status under the code as they cannot be considered to be epi-types but are useful in connection with future identification of some of the rare taxa. Illustrations of the floral parts of can be found in Ridsdale (1989). ACKNOWLEDGEMENTS I would like to thank Dr. J.F.Veldkamp for help with the Latin descriptions. LITERATURE RIDSDALE, C.E. 1979.

Two printed copies (on A4 paper) of the manuscript of not more than 200 pages should be sent to Editors, together with an electronic copy prepared on Word Processor computer programme using Times New Romance letter type and saved as Rich Text File must be submitted. For the style of presentation autohrs should follow the latest issue of Reinwardtia very closely. Title of the article should be followed by author's name and mailing address and one-paragraphed abstract in English (with French or German abstract for paper in french or German) of not more than 250 words.Keywords should be given below each abstract, on a peparated paper author(s) sholud the preferred running title of the article submitted. Taxonomic keys should be prepared using the aligned-couplet type. Strict adherence to the International Code of Botanica Monenclatural is observed, so that taxonamix and nomenclatural novelties sholud be clearly shown, Latin description for new taxon proposed should be provided, and the herbaria where type specimens are deposited should be indicated. Synonyms should be presented in the long form [name of taxon, author's name, year of publication, abbreviated journal or book title, volume (number): [page]. Maps, line drawing illustrations or photographs preferably should be prepared in landscape presentation to occupy two columns. Illustrations must be submitted as original art accompanying, but separated from the manuscript. On electronic copy, the illistration sholud be saved in .jpg or .gif format. Legends for illustrations must be submitted separately at the end of the manuscript. Bibliography, list of literature cited or references follow the Harvard system.
