Dracoscirpoides having six to seven bristle-like perianth segments (Muasya et al., 2012), Hellmuthia having two well-developed lateral scale-like perianth parts and a third small adaxial scale (Vrijdaghs et al., 2006; Muasya et al., 2009b) (Fig.
(5) the development of perianth segments is unique to the Ficinia clade and has never been reported for taxa of the Cyperus clade.
chartacea in its larger flowers (up to about twice as large in linear measurements of the perianth segments
), its sepals and petals not tinged with greenish-brown below the middle, the lateral sepals spreading above the middle (vs.
Style divided into 3 deep red clavate branches, each branch 25-32 mm long, much exceeding the anthers and at least half the length of the perianth segments
, arising at a point well below the base of the anthers in the throat of the flower.
The magnolia's large simple flowers are borne singly at the tips of the shoots and have six to nine petals (strictly perianth segments
), which are white, cream, or reddish, and have a slight pleasant smell.
The diaspores of Calectasia and Kingia are both wind-dispersed, the perianth segments
in Kingia (Fig.
3 Flowers yellowish with intense honey-brown continuous blotches or with confluent dark red-chocolate spots; perianth segments
of the right side of the flower spreading at 90[degrees] to the main axis of the flower, thus parallel or subparallel to each other; central lobe of the labellum yellowish with honey-brown or dark red-chocolate tinges; plants restricted to the Candelaria and Palizada rivers, Campeche, Mexico L.
Blaser (1941) described them as organised in five fascicles corresponding with five perianth segments
, an observation that we cannot confirm (Vrijdaghs et al., 2005a).
1), have bristle-like perianth segments. Similar perianth segments, some well developed and others rudimentary, have been observed in Ficinia material (Muasya et al., unpublished results).
Recent floral ontogenetic studies (Vrijdaghs et al., 2006) have revealed an adaxially situated third scale in some proximal flowers in spikelets of Hellmuthia, and these are interpreted to be perianth segments and not glumes of reduced florets as in Mapanioideae.
We expand the tribal circumscription to include characters states such as the occasional presence of floral scales and bristle-like perianth segments, observed in the Ficinia clade.
