ABSTRACT The distribution of mucilage cells in vegetative parts the dicotyledons is reviewed on basis an extensive literature study. Mucilage or slime occur 144 families, belonging to 47 orders as defined Takhtajan's system classification. Their systematic and diagnostic value at different levels taxonomic hierarchy discussed. Although are generally species level, variation within genera families seriously limits significance mostphylads. core Malvales, which all mucilaginous, constitute...
Data on fossil dicotyledonous wood were assembled in order to 1) test the Baileyan model for trends of specialisation anatomy by addressing question - 'primitive' anatomieal features (as defined model) more common geologie past than at present?, 2) infer, a broad geographie scale, climatie regimes, and long term climatic change, 3) assess extent knowledge woods. The resulting database has information 91 over 1200 incidence selected anatomical was plotted through time (by epoch) world two...
Ecological trends for occurrence of certain vessel, tracheid and fibre characteristics. have been analysed 505 species (belonging to 221 genera 71 families) from Europe, Cyprus, Madeira. Macroclimatic gradients boreal, via temperate mediterranean are strongly related with a decreasing incidence scalariform perforations, (almost) exclusively solitary vessels, fibre-tracheids (i. e., fibres distinctly bordered pits). In this sequence the different vessel size classes (vessel dimorphism)...
Information from the Inside Wood database (5,663 descriptions) was used to determine relative abundance of selected IAWA Hardwood List Features, for whole world and broad geographic regions in List. Features that occur more than 75 % records are: growth ring boundaries indistinct or absent, diffuse porosity, exclusively simple perforation plates, alternate intervessel pitting, non-septate fibers. The distribution vessel element features found this study is consistent with previous studies:...
Wood identification is of value in a variety contexts - commercial, forensic, archaeological and paleontological. This paper reviews the basics wood identification, including problems associated with different types materials, lists commonly used microscopic macroscopic features recent anatomical atlases, discusses ofkeys (synoptic, dichotomous, multiple entry), outlines some work on computer-assisted identification.
In a sample of 71 specimens belonging to 31 species the genus Sympiocos (Symplocaceae), vessel diameter, member length, wall thickness, fibre and ray height decrease with increasing latitude provenance, whilst frequency incidence spiral thickenings increase.Similar but weaker trends were found for altitude exceptions thickness.The number bars per perforation varies independently or latitude.These results confirm extend earlier findings, support general validity these -probably partly...
The wood anatomical diversity of the woody Myrtales, comprising Combretaceae, Lythraceae (including Alzatea), Melastomataceae Crypteroniaceae), Myrtaceae, Oliniaceae, Onagraceae, Penaeaceae, Punicaceae (can also be included in Lythraceae), Psiloxylaceae, Sonneratiaceae and Thymelaeaceae, is summarized. All these families share intraxylary phloem vestured pits, their other attributes represent parts continuous, sometimes divergent, often parallel, specialization series. Rhizophoraceae,...
Abstract Araucarioxylon Kraus is a widely known fossil‐genus generally applied to woods similar that of the extant Arau‐ cariaceae. However, since 1905, several researchers have pointed out this name an illegitimate junior nomenclatural synonym. At least four generic names are in current use for fossil wood type: Agathoxylon Hartig, , Dadoxylon Endl. and Dammaroxylon J. Schultze‐Motel. This problem inconsistent application compounded by fact type represent wide range plants including basal...
The incidences of selected features dicotyledonous wood that are believed to be ecologic and/or phylogenetic significance (distinct growth rings, narrow and wide vessel diameter, high low frequencies, scalariform perforations, tangential arrangement, ring porosity, helical wall thickenings) were plotted through time (Cretaceous–Recent). There marked differences between the Cretaceous Tertiary in frequency all anatomical features. Incidences associated with markedly seasonal climates extant...
Abstract Aim A comparison of biodiversity patterns within Malesia in relation to surface area. Location Analysis the species richness and endemism vascular plants five major Malesian islands, i.e. Java, Sulawesi, Sumatra, Borneo New Guinea. Methods Available data on ranges correlation with area respective islands were examined this work. Estimations total numbers for these are presented based extrapolation all available published Flora Malesiana information recent checklists, comprising...
Bordered pits play an important role in permitting water flow among adjacent tracheary elements flowering plants. Variation the bordered pit structure is suggested to be adaptive optimally balancing conflict between hydraulic efficiency (conductivity) and safety from air entry at membrane (air seeding). The possible function of vestured pits, which are with protuberances secondary cell wall chamber, could increased resistance or minimized vulnerability seeding. These functional hypotheses...
A comparison is made between ecological trends in wood anatomy found southern California and Israel adjacent regions. Trends for type of vessel perforation, member length the occurrence helical thickenings show striking parallels. Characters like diameter frequency incidence (fibre-)tracheids only weakly similar trends. Vessel grouping ring-porosity do not any parallel data Israel. The differences two floras can largely be attributed to different floristic composition alternative...
The wood anatomy of 37 species belonging to the eight genera Ulmaceae native China is described. Chinese characterised by mostly simple perforations (sporadic scalariform plates occur in Hemiptelea and Zelkova ); altemate, non-vestured intervessel pits; relatively short vessel elements fibres; non septate fibres with minutely bordered pits confined radial walls; mainly paratracheal parenchyma; rays rarely higher than 1 mm. Tanniniferous tubes are reported for first time Ulmaceae; they...
