Pollen morphology of the subtribe Cuspariinae (Rutaceae)

  title={Pollen morphology of the subtribe Cuspariinae (Rutaceae)},
  author={Cynthia M. Morton and Jacquelyn A. Kallunki},
The neotropical subtribe Cuspariinae (Rutaceae) comprises as many as 26 genera and over 125 species. Pollen grains from 111 collections representing 71 species and 24 genera were examined by LM, SEM, and TEM. The pollen morphology of this subtribe is very diverse. Grains are mostly 3–6-aperturate and colporate, rarely porate (Spiranthera) or pantocolporate (Almeidea). Exine sculpturing is most commonly reticulate, sometimes perforate, foveolate-perforate, foveolate, foveolate-reticulate… Expand

Pollen morphology of the genus Skimmia (Rutaceae) and its taxonomic implications
Pollen morphology of the genus Skimmia was studied and it was found that pollen dimorphism is suggested in the aperture number in accordance with the floral system. Expand
A Revision of Conchocarpus with Pantocolporate Pollen Grains: The Almeidea Group (Galipeinae, Rutaceae)
Abstract Conchocarpus is the largest genus of Galipeinae (tribe Galipeeae), which is the most diverse group of Neotropical Rutaceae, with ca. 50 species. Recent phylogenetic analyses support aExpand
Almeidea A. St.-Hil. Belongs to Conchocarpus J.C. Mikan (Galipeinae, Rutaceae): Evidence from Morphological and Molecular Data, with a First Analysis of Subtribe Galipeinae
A phylogenetic analysis of Almeidea is performed, using a broader sampling of Galipeee and other Neotropical Rutaceae, the first such study focused on this subtribe, and showed Galipeinae as monophyletic, with the species of AlMEidea also monophylets and nested in a clade with a group of species of Conchocarpus, a non-monophyletics group.

Pollen morphology of species of Hortia (Rutaceae)
A palinological study covering all 10 species of the Neotropical genus Hortia Vand demonstrated that the genus is stenopalynous, with pollen grains in monads, subprolate to prolate, 3-colporate, with very thick exine and a psilate-perforate pattern of ornamentation. Expand
A tree nymph of the Brazilian Atlantic Forest: Dryades (Galipeinae, Rutaceae), a new neotropical genus segregated from Conchocarpus.
Results showed Conchocarpus as polyphyletic with its species divided in two clades, one of which includes the type species C. macrophyllus and the other includes C. concinnus suggesting a close phylogenetic affinity. Expand
Sequence data from 65 species in 59 genera that represented all subfamilies and tribes and more genera of Toddalioideae and of neotropical groups than previous studies are included to assist with the much-needed suprageneric reclassification and with studies of evolution of chemical compounds and biogeographic history of the Rutaceae.

Pollen morphology of Diosma and Coleonema (Rutaceae: Diosminae) and its taxonomic implications
Pollen data support macromorphological evidence that suggests the generic re-classification of the Diosminae, and species groupings indicated by the pollen types suggest possible relationships between species within Coleonema and with other genera that were not previously apparent. Expand
Pollen morphology and evolutionary history of Sapindales
This study aimed to compile the main pollen characters of Sapindales families occurring in Brazil through a thorough review of the literature including national or foreign taxa and to present new information on the palynology of representatives of the families. Expand
Floral biology and pollination of two sympatric species of Galipeinae (Galipeeae, Rutaceae) endemic to the Brazilian Atlantic Forest☆
The results indicate that the function of staminodes in the biology of the species may have influenced their maintenance throughout the floral evolution of Galipeinae. Expand
Pollen morphology of Phyllosma and Sheilanthera (Diosminae: Rutaceae) and its taxonomic implications
Pollen morphology of all three species was investigated by LM, SEM and TEM to shed light on their relationships to other genera of the subtribe Diosminae, Rutaceae, and the macromorphological characters of the species correspond to the pollen morphology. Expand


A revision of Erythrochiton sensu lato (Cuspariinae, Rutaceae)
In the rutaceous subtribe Cuspariinae, species with relatively large, valvate, colored calyces have been assigned to Erythrochiton, but differences in arrangement of leaves, type of inflorescence, union of petals, of filaments, and of carpels argue for the recognition of three genera. Expand

Two main types may be distinguished within Alectryon pollen: the colporate type and the parasyncolporate type. These types are not clear-cut, but merge into each other through a complete series ofExpand
Chemosystematics of theRutaceae: Suggestions for a more natural taxonomy and evolutionary interpretation of the family
The chemosystematics of Rutaceae is reviewed on the basis of updated surveys of various secondary metabolites and their biosynthetic derivation, and a stepwise replacement of benzylisoquinolines by simple and complex anthranilic acid derived alkaloids, and eventually by coumarins and/or limonoids is confirmed.
