Abstract This volume treats the microscopic anatomy of vegetative organs of two monocotyledonous flowering plant families. Observations are included for Acorus, sole genus of Acoraceae, and nearly all of the 106 genera of the family Araceae, now including the duckweeds as the subfamily Lemnoideae.

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
1980Several 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 ...

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 ...

Mitotic Cycles in Dicotyledons and Monocotyledons
Nature, 1971THE 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

The Quarterly Review of Biology, 1973
A brief survey of types of branch attachment in monocotyledons shows a wide range of morphological possibilities. This diversity is duscussed in the light of recent analytical studies of the development of the vascular system in monocotyledons, expecially in the larger, woody forms which have a special interpretive appeal. Vascular interlinkage is seen

Criteria for the Monocotyledons
1985We have accepted here the hypothesis that the monocotyledons are monophyletic on the basis of two character conditions: (1) they have a single cotyledon, or according to an alternative interpretation no cotyledon at all, whereas the dicotyledons have two (other numbers such as 0, 1, 3 or more are obviously secondarily derived); (2) their sieve tube ...

Abstract This volume provides a comprehensive account of the systematic vegatative anatomy of the plant family Iridaceae. The iris family includes several horticulturally important genera, such as Iris Crocus, Gladiolus and Freesia, and many others of potential horticultural value.
