Caryophyllaceae - Paronychioideae - Paronychieae - Pollichia Aiton

Description :

  • Scandent, pilose subshrubs, freely branched, with rather stiff branches
  • Leaves clustered at nodes to form false whorls, usually linear, sometimes lanceolate; stipules free, scarious
  • Inflorescences dense, subsessile, axillary cymes, surrounded by white, scarious bracts, and each flower subtended by a bracteole; after anthesis each cyme forms a fleshy (berry-like) infructescence due to swollen bracts and peduncles
  • Flowers bisexual, perigynous, sessile; receptacle cupuliform, as long as sepals
  • Sepals 5, free, small
  • Petals 5, minute, scale-like, white
  • Stamens 1 or 2, inserted on 5-lobed nectary disc
  • Ovary 1-locular; ovules 2, basal, on short funicles; style 1, filiform, persistent
  • Fruit 1-seeded, indehiscent, enclosed by persistent calyx and borne with several other fruits in milky white to reddish brown berry-like infructescence in which rachides and lower parts of bracts are enlarged and fleshy
  • Seeds 1 or 2, ± ovoid; embryo curved
  • x = 9 (1 report, polyploidy)
