Geographic variation in Crowea exalata (Rutaceae) and the recognition of two new subspecies

  title={Geographic variation in Crowea exalata (Rutaceae) and the recognition of two new subspecies},
  author={Wayne A. Gebert and Marco F. Duretto},
Crowea exalata F.Muell. was sampled throughout its morphological and geographical range to test the validity of the current circumscription of the species and subspecies. Through numerical analysis of morphological and chemical (leaf flavonoids and volatile oils) data four taxa are recognised, subsp. exalata, subsp. revoluta Paul G.Wilson, subsp. magnifolia Gebert subsp. nov. and subsp. obcordata Gebert subsp. nov. Descriptions and a key to all taxa are provided.

Major Clades of Australasian Rutoideae (Rutaceae) Based on rbcL and atpB Sequences
This comprehensive molecular phylogeny of the Australasian Rutoideae gives a broad overview of the group’s evolutionary and biogeographic history and provides a basis for taxonomic revision and a necessary framework for more focused studies of genera and species.


Analysis of hybridization between Eucalyptus pauciflora Sieber ex Spreng. and E. radiata Sieber ex DC. (Myrtaceae)
The data from adult and seedling morphology, flavonoid composition, and volatile oil composition of the plants studied prove that they are indeed hybrids between the two species of Eucalyptus; however, these data also indicate some interesting problems in the application of some of these techniques to this particular situation.
Geographic Variation in Eucalyptus diversifolia (Myrtaceae) and the Recognition of New Subspecies E. diversifolia subsp. hesperia and E. diversifolia subsp. megacarpa
Patterns of geographic affinity between populations are consistent with a hypothesis of genetic exchange between normally disjunct regional populations of E. diversifolia via coastal land-bridges exposed during periodic times of low sea level since the mid Tertiary.
Volatile oils and the study of natural hybridization between Correa aemula and C. reflexa (Rutaceae)
A small hybrid swarm between Correa aemula and C. reflexa was located and examined morphologically and chemically, with an emphasis on volatile oils, and it was found that ordination is a more useful technique for the study of hybridization than is classification.
Patterns of variation and relationships in the Eucalyptus Alpina–E. baxteri complex (Myrtaceae) based on leaf volatile oils
Phenetic and phylogenetic analyses were undertaken of the leaf volatile oil composition of the sampled plants, and E. arenacea emerges as a cohesive, monophyletic species, while E. baxteri is a variable and probably paraphyleticspecies.
A new species of stringybark, Eucalyptus mackintii, from eastern Victoria and its phenetic and cladistic relationships
Populations of stringybark trees from East Gippsland, with affinities to Eucalyptus macrorhyncha, were studied by pattern analyses of adult and seedling morphology, leaf volatile oils and flavonoid
Morphological Variation within the Boronia grandisepala Group (Rutaceae) and the Description of Nine Taxa Endemic to the Northern Territory, Australia
Within Boronia Sm. section Valvatae (Benth.) Engl. the B. grandisepala F.Muell. species group is characterised by a calyx as large or larger than the corolla, simple leaves, and multiangular stellate
Chemical documentation of allopatric introgression in Juniperus.
Chemical data from volatile extracts of leaf foliage obtained from an array of populations of juniperas virginiana and juniperus virginiana are examined for allopatric introgression.
Analysis of a hybrid swarm between Acacia brachybotrya and A. calamifolia (Leguminosae)
A hybrid swarm between Acacia brachybotrya and A. calamifolia, involving plants referable to A. grayana, was studied in detail and confirmed as hybrids and other intermediate plants are determined as backcrosses to either parent.
Population ecology of Banksia saxicola (Proteaceae)
P Phenetic classification and ordination analyses indicated that population differences are present but individual plants do not exclusively group into geographically isolated populations, and Banksia saxicola had the highest level of serotiny.
Variation and Evolution in the Genus Flindersia (Rutaceae). II. Review of Methods for Geographic Variation Analysis of Volatile Oil Data
The genus Flindersia is currently being studied as it provides an ideal system for the investigation of variation and evolution in a group of tropical tree species. The first stage in this
