Naucleeae

Flower heads of Sarcocephalus latifolius, photographed by Scamperdale.


Belongs within: Cinchonoideae.

The Naucleeae are a pantropical clade in the plant family Rubiaceae, though the greater part of their diversity are found in Africa and Asia with only a few Neotropical species. Razafimandimbision & Bremer (2001) diagnosed Naucleeae on the basis of their globose spherical heads and floral nectaries embedded in the hypanthia, as well as supporting the clade by molecular analysis.

Characters (from Razafimandimbison & Bremer 2001): Trees, shrubs, rarely lianas. Raphides absent. Terminal vegetative buds conical, flattened or pyramidal. Leaves mostly opposite, rarely whorled; stipules interpetiolar, rarely intrapetiolar, caducous, rarely persistent, entire. Inflorescences terminal, lateral, or both lateral and terminal, congested into spherical heads. Flowers 4-5(-6)-merous; corolla aestivation imbricate or valvate; floral nectaries present, inconspicuous, embedded in hypanthia and ovaries. Stamens with filaments shorter than anthers; anthers mostly basifixed, rarely medifixed. Ovary bilocular, placentas attached to base, one third, middle, upper third, or apex of septa, with one to numerous predominantly imbricately pendulous, or ascendent ovules in each locule. Fruits mostly free, sometimes fused into multiple, succulent fruits; capsular fruits dehiscing loculicidally, septicidally, or both, mostly from base, rarely from top. Seeds winged or not; exotestal cells with thickenings along inner tangential wall. Secondary pollen presentation present, with pollen deposited on immature stigmatic lobes. Pollen tricolporate.
