The synapomorphies that link these taxa are the slightly curved tube (character 31) and the conical trichomes inside the flower (33).
As shown above, pollen characters provide synapomorphies for various levels of groupings within Arctotideae, including the two subtribes, Arctotidinae and Gorteriinae, the grouping of Eremothamnus and Hoplophyllum, the smaller GAZ and DID clades, the BER clade excluding Cuspidia, and the DID-BER clade (Fig.
Kochiana synapomorphies include accessory keels on male palpal bulb (character 4 in Table I), and putatively a medial crest on embolus apex (character 5 in Table I), horn-shaped spermatheca (character 9 in Table I) and spermatheca with large granules (character 13 in Table I) (Fig.
glenoides supported on their common branch by the massive movable process; however, further synapomorphies are needed to test the monophyly of either the C.
Members of the Canellaceae form a monophyletic group, which share several synapomorphies such as monadelphous stamens, parietal placentation, and campylotropous ovules (Salazar, 2006).
The rhodopis Series, containing the rhodopis group, is not definable because no synapomorphies are apparent.
Guyer and Slowinski's "well corroborated" trees simply had an internal node supported by at least five synapomorphies.
Further new or modified synapomorphies which are important as diagnostic characters for this group are: caudal and anal fin proximal portion spotted, with broad light submarginal band and dark margin; absence of dark margin on dorsal fin; absence of spots on head; absence of black margin to the scales.
7), and six of the eight mapped characters are recovered as synapomorphies (Fig.
One of Dondale's (1986) synapomorphies of the Venoniinae was "embolus small, situated distally;" however, it has been shown recently that the embolus in species of Venonia Thorell 1894, the type genus of the subfamily, originates prolaterally and curves ventrally around the embolic division challenging Dondale's (1986) concept of the subfamily (e.
Some synapomorphies are numbered: (2) sacral fusion, (3) fifth toe longer than third, (4) massive crests borne on lateral edges of frontoparietals.
