Chromosome numbers are reported for 69 species, belonging to 11 genera of the Boronieae. In comparison with the other divisions of the Rutaceae, chromosome numbers are remarkably variable, and base numbers range from 7 to 19. Seven genera and 10 species belonging to other tribes and subfamilies of the Rutaceae are also reported. In common with the Aurantoideae, Xanthoxyleae, and Ruteae, the primitive number in the Boronieae is almost certainly 9. Chromosomal evolution has involved both… 
Chromosome studies in the tribe Clauseneae and the cytological homogeneity in the orange subfamily (Aurantioideae, Rutaceae)
Abstract  Chromosome numbers for 21 Rutaceous species, representing five genera (Bergera, Clausena, Glycosmis, Micromelum, and Murraya) in the tribe Clauseneae (Aurantioideae, Rutaceae) were
Basic chromosome number in Boronia (Rutaceae)— competing hypotheses examined
Regression analysis indicated that Boronia chromosome number has a significant negative relationship with evolutionary distance, which generally supported the present classification of Boronia species.
An investigation of chromosome numbers in the genus Brachiaria (Poaceae: Paniceae) in relation to morphology and taxonomy
Determinations of chromosome number and morphological studies of 260 populations, belonging to 32 taxa, of the genus Brachiaria from the Indian subcontinent reveal that all sexually reproducing taxa
Remarks on karyological differentiation patterns in tropical woody plants
Karyomorphology suggests a new systematic arrangement for the Laurales, a new circumscription of theCymbopetalum tribe (Annonaceae), and a placement of theCochlospermaceae/Bixaceae in theViolales.
Karyotype evolution in the genus Boronia (Rutaceae)
Analysis of chromosome number, variations of total chromosome length (TCL) and average chromosomes length (ACL), Nombre Fondamental (NF) and karyotype asymmetry suggest that dysploid reduction is the major mechanism in Boronia karyotypes evolution.
Molecular phylogeny of Phebalium (Rutaceae: Boronieae) and related genera based on the nrDNA regions ITS 1+2
Parsimony analyses of the internal transcribed spacer regions of nuclear ribosomal DNA for 38 taxa sampled from the Phebalium group confirm that, with the exception of PheBalium sensu stricto and Rhadinothamnus, six of the currently recognised genera within the group are monophyletic.
Chromosome numbers and their evolutionary meaning in the Sapindales order: an overview
A great diversity of chromosome numbers in each family is found, especially in Rutaceae, Sapindaceae, and Meliaceae, which confirms the importance of numerical chromosome changes in the diversification of families and genera.
New chromosome numbers in Homoranthus (Myrtaceae: Chamelaucieae) and notes on their taxonomic utility
Diploid chromosome counts are reported for the first time for 23 species of Homoranthus (Myrtaceae) and published counts are confirmed for a further three species. H. wilhelmii (F.Muell.) Cheel was
Cytological notes in Rutaceae. 1: Boronia tenuis
A new chromosome number determination for Boronia tenuis (n=16) corrects a prior report and has implications for the cytotaxonomy of Boronia in Western Australia.
Genomic relationships within Boronia (Rutaceae) as revealed by karyotype analysis and RAPD molecular markers
Dendograms supported cytological results, indicating B. heterophylla and B. molloyae are closely related and clearly distinct from B. purdieana, and Chromosome morphology indicated a closer relationship between B. megastigma and B .
