CYCADEOID SÖZCÜĞÜ İNGILIZCE DİLİNDE NE ANLAMA GELİR?
Bennettitales
Bennettitales, Triass döneminde ilk ortaya çıkmış tohum bitkilerinin soyu tükenmiş bir düzenidir ve bazı Bennettitales'in Tazmanya ve doğu Avustralya'da Oligosen zamanlarında ayakta kalmış görünmesine rağmen, Cretaceous'un sonlarına doğru birçok alanda tükenmiştir. Bazıları, kalın ağaç gövdeleri ve sikadlarınkilere yüzeysel bir benzerlik kazandıran, kıvrımlı bileşik yapraklarla karakterize edilmişlerdir ve esasen stomal aranjman farklıdır. Takson, Cycadeoidea ve Monanthesia'nın stut gövdeleri ve bisporanjit strobili ile temsil ettiği iki ana grubu, ve Williamsonia, Williamsoniella, Wielandella ve Ischnophyton'un yanı sıra ince, dallanmış gövdeli bisporanjit veya monosporanjit strobili de içeren iki gruptan oluşur. Bennettitales antofitler arasına yerleştirilmiş ve bir süre çiçek benzeri üreme yapıları nedeniyle çiçekli bitkilerin yakın akrabaları olarak kabul edilmiştir.

That the cycadeoid alliance as a whole was of cosmopolitan distribution all
through the Mesozoic should indicate the further capacity to live in the most
varied climates, as already maintained. But that which it is especially desired to
point out is ...

Paleobotany and the Evolution of Plants
First, cycadeoid ovules are small (up to 3 mm long), unlike the much larger seeds
of the medullosan pteridosperms. Although debatable, the nucellus of cycadeoid
ovules is said to be fused with the integument except in the apical region.

Known unisexual Triassic cycadeoid fructifications probably represent dispersed
abscised microsporangiate complexes or ovulate receptacles preserved after the
abscision of their microsporangiate organs. Cones of the cycadeoids are ...

The frond-borne pollen organ of some Paleozoic seed fern has been postulated
as the progenitor of the Mesozoic cycadeoid cone (Delevoryas, 1968a, 1968b).
According to this foliar hypothesis, there has been a progressive reduction of a ...

Based on the microstructures of the laminae and petiole, the plant organs found
in the nodules appear to be most comparable to members of the Cycadeoi- dales
and suggests that at least one species of cycadeoid provided browse for ...

We cannot quite ignore the view stressed by Gupta, that Homoxylon
rajmahalense may after all have been the wood of a cycadeoid, not of a primitive
dicotyledon. But supposing that it was a cycadeoid — and there is nothing to
prove that it ...
