“…A shared feature of all three genera studied here is the presence of postgenitally united carpel tips (style and stigma), as known from most other Rutaceae (Endress et al, 1983;Ramp, 1988;Caris et al, 2006;Wei et al, 2012). In Galipeinae, it was first observed in E. brasiliensis by Ramp (1988).…”

“…Both N. pulverulenta and C. tricoccon have been described as andromonoecious (Tébar & Llorens, 1997) but N. pulverulenta might be (functionally) androdioecious (Lorenzo & al., 2003). Additionally, septal cavities in the ovules were found in C. tricoccon but are absent in N. pulverulenta (Schmid, 1985;Caris & al., 2006). Apart from these characters, the two species are very much alike.…”

Cneorum trimerum (Urban) Chodat is only known from the type specimen collected in 1861 in eastern Cuba. The species has sometimes been regarded as a synonym of C. tricoccon L., which is otherwise confined to the Mediterranean. As no other Cneorum specimens are known from Cuba, the specimen is a mysterious finding with a disputed taxonomic rank. The goal of this study is to clarify the status of the Cuban specimen using molecular and wood anatomical data. We succeeded in extracting DNA out of the 150 year old type specimen in our ancient‐DNA lab and amplified two chloroplast markers (atpB, trnL‐trnF) and one nuclear marker (ITS). Comparison of the sequence data with several sequences from C. tricoccon clearly suggests inclusion of the Cuban specimen into the latter species; wood anatomical features confirm the molecular results. The transatlantic distribution of C. tricoccon is probably the result of an introduction in Cuba by humans.

“…In Rutaceae, the most early-diverging lineage Cneoroideae is represented by haplostemony [ 1 ]. Most genera in this subfamily have small haplostemonous flowers like Cneorum [ 51 ]. The ancestral state reconstruction also showed that haplostemony is the ancestral character in Rutaceae.…”

Phylogenetic Relationships and Evolution of the Androecia in Ruteae (Rutaceae)

Ruta, which belongs to tribe Ruteae, is the type genus of the subfamily Rutoideae and the family Rutaceae. Molecular systematic studies have shown that the genera in Ruteae are closer related to Aurantioideae than to most other genera of Rutoideae, some of the genera traditionally placed in Ruteae have been shown to be nested within the Aurantioideae clade, but the diagnostic characters for determining new patterns in the relationship are poor. In this study, we investigated the floral development of Boenninghausenia in Ruteae (sensu stricto), Haplophyllum in the basal position of Aurantioideae and Murraya in traditional Aurantioideae using scanning electron microscopy. The androecium of Boenninghausenia is obdiplostemony. As androecia in other genera within Ruteae (s.s.) are also obdiplostemonous, reconstruction of the ancestral state indicates that obdiplostemony is an ancestral character in this clade. Because the androecia of Haplophyllum and Murraya are also obdiplostemonous, obdiplostemony is also an ancestral character in Aurantioideae clade. The ancestral state reconstruction indicates this character can serve as a synapomorphy of the Ruteae-Aurantioideae clade. The results of our work also shed light on the evolution of the androecium in Rutaceae, as the obdiplostemony of this group is clearly derived from haplostemony in the ancestral genera in Rutaceae and has develop into polyandry by increasing antepetalous stamens.
