Other claims from this paper (14)
- Observation Eriocaulaceae staminate and pistillate flowers were trimerous except dimerous P. flaccidus.
- Observation Staminate flowers of these species had isostemonous androecia.
- Observation Four species had microscopic scalelike staminodes adnate to the filament base.
- Observation Pistillate staminodes were reduced and adnate to the petal basis except in R. roraimae.
- Observation Pistillate flowers had solid unvascularized styles interspersed with vascularized nectariferous appendages.
- Observation Nectariferous appendages were homologous to styles.
- Observation An isostemonous androecium was interpreted as a derived reduction from a diplostemonous ancestor.
- Observation Staminode traits indicated a probable basal position of R. roraimae within Paepalanthoideae.
- Observation Nectariferous appendages could be ancestral or derived from gynoecial modification.
- Observation C. riedelianus had oblong, poricide, yellow anthers.
- Observation C. riedelianus had a superior, tricarpellar, trilocular, uniovulate ovary.
- Observation C. riedelianus had a simple hollow style and reduced stigma.
- Observation Floral epidermal cells contained phenolic compounds, possibly associated with herbivory protection.
- Observation Authors suggested C. riedelianus anthers attract pollinators with pollen rewards in the absence of floral nectaries.
