The pollen morphology of 85 species (89 collections) from 32 genera, i.e. Ancistrocarpus, Apeiba, Berrya, Brownlowia, Carpodiptera, Christiana, Clappertonia, Colona, Corchorus, Desplatsia, Diplodiscus, Duboscia, Eleutherostylis, Entelea, Erinocarpus, Glyphaea, Goethalsia, Grewia, Hainania, Heliocarpus, Luehea, Lueheopsis, Microcos, Mollia, Mortoniodendron, Pentace, Sparmannia, Tetralix, Tilia, Trichospermum, Triumfetta, and Vasivaea of family Malvaceae was examined by light microscope (LM… 
Pollen Morphology of Malvaceae s.l. from Cerrado Forest Fragments: Details of Aperture and Ornamentation in the Pollen Types Definition
ABSTRACT We analyzed the pollen morphology of 13 Brazilian native species of Malvaceae s.l. from forest fragments of Cerrado belonging to nine genera [Bastardiopsis (K. Schum.) Hassl., Byttneria
The subfamily Malvoideae (Malvaceae s.l.) in the western of the Sucre state, Venezuela.
As result of the floristic of members of the subfamily Malvoideae (Malvaceae sl) inventory realized out in the municipalities of the western of the Sucre state, 41 species included in the following genera were identified.
Pollen morphology of selected species of the subfamily Bombacoideae (Malvaceae sensu lato)
The variation in the pollen morphology confirms the eurypalynous status of the genera studied here, and separates Ceiba and Eriotheca from the other genera.
Comparative study of anther development, microsporogenesis and microgametogenesis in species of Corchorus, Heliocarpus, Luehea and Triumfetta Malvaceae: Grewioideae) from South America
This is the first embryological report of the Grewioideae subfamily, contributing to the characterization of the genera studied and the results are discussed in relation to the known data for the family.
On the relevance of molecular tools for taxonomic revision in Malvales, Malvaceae s.l., and Dombeyoideae.
An overview of changes to the taxonomy of Malvales is presented, and three possible taxonomic schemes as part of an ongoing revision of the Mascarene Dombeyoideae are proposed.
Singpuria, a new genus of Eudicot flower from the latest Cretaceous Deccan Intertrappean Beds of India
A new bisexual flower, Singpuria kapgatei, gen. et sp. nov., is described from chert of latest Cretaceous age from the Deccan Intertrappean Beds at Singpur, Madhya Pradesh, in central India. The
The distribution and pollen morphology of some Grewia species in Nigeria were studied. These species occupy a wide range of habitats; six species (G. malacocarpa Mast., G. barombiensis K.Schum., G.
A preliminary leaf epidermal and pollen morphology of some West African species of Desplatsia Bocq
The ora size, lumen width, number of epidermal cell and stomata are additional taxonomic characters that can be used for species delimitation in the genus Desplatsia.
Combined LM and SEM study of the middle Miocene (Sarmatian) palynoflora from the Lavanttal Basin, Austria: part IV. Magnoliophyta 2 – Fagales to Rosales
Köppen signatures of potential modern analogues of the fossil Fagales and Rosales suggest a subtropical climate at lower elevation and subsequent subtropICAL to temperate climate with altitudinal succession in the Lavanttal area during accumulation of the palynoflora.


Catálogo sistemático dos pólens das plantas arbóreas do brasil meridional: V - Leguminosae: Papilionatae
In this paper of the catalogue of south brazilian arboreal pollen grains, the autor deals with the Papilionatae, and finds a large correspondence with the morphology of the present pollen grains.
Phylogenetic Relationships and Floral Evolution of the Byttnerioideae (“Sterculiaceae” or Malvaceae s.l.) Based on Sequences of the Chloroplast Gene, ndhF
Results imply that the unusual hooded petals of many Byttnerioideae are plesiomorphic for the clade, with subsequent transitions to large, flat petals or small, scale-like petals that lack a distinct hood.
Support for an expanded family concept of Malvaceae within a recircumscribed order Malvales: a combined analysis of plastid atpB and rbcL DNA sequences
Sequence analyses of the plastid genes atp B and rbc L support an expanded order Malvales and propose to merge Sterculiaceae, Tiliaceae and Bombacaceae with Malvaceae and subdivide this enlarged family Malvoideae into nine subfamilies based on molecular, morphological, and biogeographical data.
The results show the extreme importance of adequate authentication of pollen type-material and suggest that in Britain both T. cordata and T. platyphyllos are native, but that much hybridization has occurred between them, giving progeny in which the somatic phenotypes show less indication of 'platyphyLLos' parentage than the pollen seems to do.
Circumscription of the Malvales and relationships to other Rosidae: evidence from rbcL sequence data.
A two-step parsimony analysis on 125 rbcL sequences to clarify the composition of Malvales, to determine the relationships of some controversial families, and to identify the placement of the MalVales within Rosidae strongly support the monophyly of the core malvalean families.
Phylogeny of the core Malvales: evidence from ndhF sequence data.
There has been extensive homoplasy in characters previously used to delineate major taxonomic groups in core Malvales, and it is suggested that /Malvatheca do not have as a synapormophy monothecate anthers, as has been previously supposed but, instead, may be united by dithecate, transversely septate (polysporangiate) anothers.
Rasterelektronenmikroskopische und morphometrische Untersuchungen an Tilia-Pollen
Proposed new realignments in the angiosperms
Our attempt at putatively phylogenetic classifications of Angiospermae, considering our vast ignorance of more than 120 million years of evolution of the class, must be very tentative and elastic to
Angiosperm phylogeny inferred from 18S rDNA, rbcL, and atpB sequences
A phylogenetic analysis of a combined data set for 560 angiosperms and seven outgroups based on three genes, 18S rDNA, rbcL, and atpB representing a total of 4733 bp is presented, resulting in the most highly resolved and strongly supported topology yet obtained for angiosPerms.
Catálogo sistemático dos pólens das plantas arbóreas do Brasil Meridional: XVII - Elaeocarpaceae e Tiliaceae
A clear separation of the four species of the genus Sloanea at palynologic basis could rot be achieved and only S. monosperma shows characteristic aspects.
