Key to the species of the genus Scleria (Cyperaceae) in Costa Rica based on the morphology of achenes
(2016)
We described the achenes of 21 species of the genus Scleria reported in Costa Rica using 16 morphological characters and developed a key based only on achene characteristics. Specimens deposited in herbaria in Costa Rica ...

Achene dimorphism in Bidens pilosa L. (Asteraceae) as determined by germination test
(Brazilian Archives of Biology and Technology, 1998-06-01)
The germination of achenes of Bidens pilosa L. was analyzed during the life span of the mother plant. Decrease in the range of achene size was monitored until the senescence of the mother plant when the shortest achenes ...
