Hoffm.(Asteraceae)? ‐Taxon41: 193–198. 1992. ‐ ISSN 0040‐0262.The two South African‐Namibian generaHoplophyllumandEremothamnusshare two unique floral microcharacters. It is concluded that they are sister groups belonging in an extended tribeEremothamneae.

SummaryRobinson, H.: Observations on the unique form of sweeping hairs on the styles of theEremothamneae (Asteraceae). ‐ Taxons:199–200. 1992. ‐ ISSN 0040‐0262.The same, unique type of stylar sweeping hairs that had been used in defining the originally monogeneric tribeEremothamneaehas been found inHoplophyllum.This underscores the close relationship ofHoplophyllumandEremothamnusand the distinctness ofEremothamneaeto which they both belong.

SummaryRettig, J. H., Wilson, H. D.&Manhart, J. R.: Phylogeny of the Caryophyllales ‐ gene sequence data. ‐Taxon41: 201–209. 1992. ‐ ISSN 0040‐0262.Phylogenetic relationships among selected families of the Caryophyllales were examined by analyses of nucleotide sequences of the large subunit of ribulose‐l,5‐bisphosphate carboxylase/oxygenase (rbcL). Sequences from 12 Caryophyllalean families were examined using parsimony and bootstrap analysis. The parsimony analysis produced two minimal trees with 778 steps. Major clades supported by bootstrap analysis are (1)Amaranthus (Amaranthaceae), AtriplexandSpinacia (Chenopodiaceae);(2)Mirabilis (Nyctaginaceae), Rivina (Petiveriaceae), Phytolacca (Phytolaccaceae)andTrianthema (Aizoaceae);(3)Basella (Basellaceae), Alluaudia (Didiereaceae), Portulaca (Portulacaceae)andSchlumbergera (Cactaceae);and (4)Silene, Dianthus, ArenariaandCerastium (Caryophyllaceae).TheCaryophyllaceaeandMollugoare the only taxa examined that do not produce betalains but they are neither closely allied nor basal to other elements of the order.Stegnospermais not allied with theMirabilis‐Rivina‐Phytolacca‐Trianthema clade. Thus, the Phytolaccaceae(s.l.) are not monophyletic.

摘要:

SummaryChappill, J. A.: Cladistics and theChrysobalanaceae. ‐ Taxon41: 211–223. 1992. ‐ ISSN 0040‐0262.In a recent monograph on theChrysobalanaceae, by Prance&White, a number of analytical methods currently employed by systematists, in particular cladistic analysis and vicariance biogeography, were criticised and dismissed as not being biologically informative. The criticisms made are discussed here, in particular the problems caused by parallelism, the detection, selection and coding of characters, and the role of functional considerations in systematics. A phylogenetic analysis is performed using the data presented in the monograph and this is compared with the classification of theChrysobalanaceaepresented by Prance&White. Some possible reasons for the discrepancies between the two are discussed.

J.: Genera ofCyperaceae:interactive identification and information retrieval. ‐Taxon41: 225–234. 1992. ‐ ISSN 0040‐0262.An automated data bank of the sedge genera of the world has been developed using the DELTA system. The 122 narrowly defined genera are described in detail in terms of morphology, anatomy, photosynthetic pathways, synonyms, ecology, distribution, and classification. This paper describes an INTKEY version of the data bank (available for MS‐DOS microcomputers), and illustrates its use for interactive identification and data retrieval.

摘要:

SummaryBelcher, R. O.: Rediscovery ofSenecio australisWilld.(Asteraceae)after nearly two centuries. ‐Taxon41: 235–252. 1992. ‐ ISSN 0040‐0262.Senecio australisWilld. is based on a Forster specimen said to be from New Zealand but has never again been collected there. Willdenow's name was misapplied by Sprengel to a taxon of theS. linearifoliuscomplex of Australia, a usage rejected by Willis (1957). Hooker and Bentham both supposedS. australisto be some part ofS. lautusG. Forster ex Willd. The question has remained controversial. It is here demonstrated that specimens collected on Norfolk Island and adjacent islets are identical with the holotype ofS. australis, and are specifically distinct from the holotype ofS. lautus.These two species are readily distinguished by consistent significant differences in calycular bracteoles, numbers of ray florets, and other features.
