Origin of the Monocotyledons

1985
The prevailing view of the origin of the monocotyledons is that they evolved from a primitive dicotyledonous group. The dicotyledons that have been considered as likely candidates in this context are almost without exception plants that we refer to one of the superorders Magnoliiflorae and Nymphaeiflorae (including Piperales) or, rarely ...

Monocotyledons

2010
Agnes Arber (1879–1960) was a prominent British botanist specialising in plant morphology, who focused her research on the monocotyledon group of flowering plants. She was the first female botanist to be elected a Fellow of the Royal Society, in 1946. This volume, first published as part of the Cambridge Botanical Handbooks series in 1925, provides an ...

Polyploidy in Angiosperms: Monocotyledons

1980
Several different estimates of polyploid frequency in angio-sperms have been made, including G.L. Stebbins’ (1,2) figure, first published in 1950, of 30–35%, and suggestions by M.J.D. White in 1942 (3) of at least 40%, and by Grant in 1963 (4) of 47%. These figures represent different ways of calculating Polyploidy and different interpretations of the ...

Mitotic Cycles in Dicotyledons and Monocotyledons

Nature, 1971
THE duration of the mitotic cycle in comparable tissues of different plant species is closely correlated with the amount of nuclear DNA1,2. In a survey of seven species Van't Hof2 showed that the average duration of the mitotic cycle in root tip meristems increases at the rate of 0.3 h/pg of DNA. Our own data agree in general with these results, but we
