Centothecoid grasses and the evolution of panicoid spikelets
(Springer Wien, 2003-09)
An evolutionary pathway leading to acrotonous, 2-flowered spikelets of Panicoideae has been suggested elsewhere, which involves apical reduction of many-flowered mesotonic spikelets. Current phylogenies of the grass family ...

Spikelet Structure in Cypereae (Cyperoideae-Cyperaceae)
(Springer, 2016-09)
This work provides an analysis of the spikelet structure in Cypereae, and their taxonomic and phylogenetic implications. The main variations in the Cypereae spikelets are seem in: number and phyllotaxis of the glumes, ...
Reproductive morphology of the early-divergent grass Streptochaeta and its bearing on the homologies of the grass spikelet
(Springer Wien, 2008-10-01)
Reproductive morphology and development are described in the Brazilian grass Streptochaeta spicata, in order to assess the homologies of the characteristic grass inflorescence, termed a spikelet, and other reproductive ...

Developmental Morphology of a Dimorphic Grass Inflorescence: The Brazilian Bamboo Eremitis (Poaceae)
(Univ Chicago Press, 2015-07-01)
Premise of research.The highly specialized grass inflorescence varies with respect to phyllotaxis, with the reproductive meristem forming primary lateral branches that are either spirally arranged or distichous. The Brazilian ...
Holocene paleoagrostological impressions from the eastern Chaco region (Argentina)
(Elsevier Science, 2015-09-18)
Although no data are available on the paleoflora of the Chaco plain, plant fossil impressions are found in the banks of the low Bermejo River, which flows along the Eastern Chaco phytogeographic region. Here, we analyze ...
