Hence, we have erectednew series and subserieswhere needed. Our initial data are derived largely from our extensivefield experience,the eucalyptcollections in the Westem Australian Herbarium (PERTH) and the CSIRO Division of Plant Industry (CANB) and frorndiscussions with colleagu€sand other collectors. In addition,we haverelied to a largeextent upon glasshousetrials to completethe comparativemorphological studies on seedlingmoryhology. Many of the new speciesoccur over a relatively wide mnge and are in sufficient abundanceor in protected areas that they are in no danger of extinction. Some arc of restricted distribution in agriculturalareas but their occurrenceon land unsuitablefor farming, e.g. lateritic breakaways,may save them and their associatedvegetation from being cleared. One of the speciesof restdcted distribution,E angularis, prodtces apparentlyhealthy buds and flowers but is not known to have set seed. Testsmay indicatethat the two populationsare actuallyprcliferations of singleindividuals, but its distinctivenessis worthy of taxonomic recognition. Most of the descriptiveterms used in the digestsfor speciesare explained and illustated in Brooker & Kleinig (1990). Itis ofpafticular valueto recognisethe tee/mallet distinction,the latterbeingahabit form peculiarto Westem Aushalia. For an accountof our taxonomicconcepts, materials and methods, and background information on studieson Westem Ausftalian eucalypts,see Brooker & Hopper (1991). Taxonomic treatment Eucalyptus ser.
