Polyploidy in Angiosperms: Dicotyledons

1980
As summarized by Goldblatt (1) in the previous article, “Polyploidy in angiosperms: monocotyledons,” recent estimates of polyploid frequency among angiosperms vary from 30–35% to 47%. The highest value is based on the postulation that haploid numbers in excess of n=13 would be mainly polyploid and those with n=13 or less would be predominantly diploid (

On Endosperm in Dicotyledons

Botanical Gazette, 1957
1. Statistical analysis of available data on the types of endosperm and of vessel perforation in dicotyledonous taxa indicates that (a) Nuclear-type endosperm is positively associated with porous perforation and that (b) Cellular-type endosperm is negatively associated with such perforation. 2. As it has been well established that porous perforation of

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

Anatomy of the Dicotyledons

1998
Abstract The first edition of the Anatomy of the Dicotyledons written by the late C. R. Metcalfe and L. Chalk in the 1950s has become a classic and widely cited reference. Responsibility for the second edition has been undertaken by the Royal Botanic Gardens at Kew where world-leading resources and specimen collections are at hand ...
