SummaryEsen, A.&Hilu, K. W.: Electrophoretic and immunological studies of prolamines in thePoaceae: II. Phylegenetic affinities of theAristideae. ‐ Taxon40: 5–17. 1991. ‐ ISSN 0040‐0262.TheAristideaeare considered to includeAristida, StipagrostisandSartidia.The phylogenetic affinity of this tribe in thePoaceaeremains controversial. To provide additional insight into the appropriate placement of theAristideae, 21 species representingAristida, Stipagrostis, Chloridoideae, Arundinoideae, andHordeum (Pooideae)were analyzed for prolamin size heterogeneity and immunological cross‐reactivities.Aristidaspecies revealed species‐specific prolamin subunit profiles. Immunological cross‐reactivities measured by the enzyme‐linked immunosorbent assay (ELISA) and immunoblotting demonstrated thatAristidawas distinct from theArundinoideaeandChloridoideae.The prolamin profile ofStipagrostisdiffered from those ofAristidaand the genus clustered with theChloridoideaeon the basis of immunological cross‐reactivities. The data indicate the heterogeneity of theAristideae, and suggest an isolated position forAristidain thePoaceaerather than its placement in either theArundinoideaeorChloridoideae.

SummaryFaden, R. B.&Hunt, D. R.: The classification of theCommelinaceae. ‐ Taxon40: 19–31. 1991. ‐ ISSN 0040‐0262.A new classification of theCommelinaceaeabove the generic level is presented. Two subfamilies are recognized, theCartonemaloideae, comprising two unigeneric tribes,CartonemateaeandTriceratelleae, and theCommelinoideae, containing the remaining 38 genera. SubfamilyCommelinoideaeis divided into two tribes,Tradescantieae, which is split into seven subtribes, each confined to either the Old or the New World, andCommelineae, which is not divided into subtribes.

SummaryMello‐Silva, R. de: The infra‐familial taxonomic circumscription of theVelloziaceae:A historical and critical analysis. ‐Taxon40: 45–51. 1991. ‐ ISSN 0040‐0262.This historical revision of the familyVelloziaceaeemphasizes a comparison between the two most recent systems of classification. The author's own opinion as to delimitation of Brazilian genera is given, and possibly represents an intermediary classification between those of Smith&Ayensu, and of Menezes.

SummaryNewton, L. E.: On the identity ofAloe pendulifloraBaker(Liliaceae/Aloaceae). ‐ Taxon40: 53–60. 1991. ‐ ISSN 0040‐0262.A recent suggestion that the poorly knownAloe pendulifloraBaker is identical withAloe confusaEngler is refuted. Living material collected in south‐east Kenya is shown to be a closer match with all that is known ofA. penduliflora.An amplified description ofA. penduliflorais provided, andA. confusais reinstated as a separate taxon.

SummarySmith, G. F.: Studies on the reproductive biology and palynology ofChortolirionBerger(Asphodelaceae: Alooideae)in southern Africa. ‐Taxon40: 61–73. 1991. ‐ ISSN 0040‐0262.While conducting biosystematic investigations towards a revision of the smaller genera of the subfamilyAlooideaeof theAsphodelaceaein southern Africa to be published in theFlora of southern Africa, I became aware thatChortolirion bergerianumDinter had not been dealt with in recent treatments of this genus. A comparative palynological and morphological study indicates thatC. bergerianumandC. angolense(Baker) A. Berger sensu lato are conspecific. Pollen grains of these taxa are free, monosulcate, bilaterally symmetrical, medium in size and have a perforated tectum.The morphological investigation and in‐vitro and in‐vivo pollen germination studies also confirmed thatChortolirionBerger represents an assemblage of both reproductive and vegetative characters that makes it unique in theAlooideae.However, the differences on which five species were previously based inChortolirionare nothing more than local variations of a variable and widespread taxon.C. bergerianumshould be included inC. angolense, the only species ofChortolirion.The taxonomic history ofC. bergerianumis also briefly discussed.

SummaryEyde, R. H.:Nyssa‐like fossil pollen: A case for stabilizing nomenclature. ‐Taxon40: 75–88. 1991. ‐ ISSN 0040‐0262.A review of the literature onNyssa‐like pollen in the fossil record reveals an unsurpassed nomenclatural snarl. There are repeated difficulties in determining whether names were validly published or not, let alone deciding on the correct name for a given taxon. Something is needed to clean up the past and avoid such snarls in the future.
