Do modern climatic niches distinguish extinct and extant plant genera in New Zealand? [PDF]

open access: yesEcol Evol
We aim to better understand New Zealand plant extinctions, often attributed to Cenozoic climate cooling, through determining if legacies of past extinction events are detectable in the climatic niches of con‐familial genera in the modern Australian floral assemblage.

The Disposition of Trichopteris (Cyatheaceae)

open access: yesAmerican Fern Journal, 1987
The delimitation of genera and families has been a persistent problem in fern taxonomy, and the Cyatheaceae sensu stricto is no exception. Christensen (190506) adopted clearly artificial genera (Cyathea, Hemitelia, and Alsophila) based on complete (totally surrounding the sorus), partial, and absent indusia.
