Soybeans are subject to potential contamination from toxic weed seeds during harvest, transportation and storage. The more common foreign seeds include those from jimsonweed, cocklebur, nightshade, cowcockle, corncockle, morning glory, castor, pokeweed, and crotalaria. This review addresses itself to the chemistry and toxic principles of these contaminants. Since jimsonweed seeds are probably t...

images inspired by the remarkable twists and turns in the shape of pollen grains from different plant species collected by the artist from specimens growing in the gardens' cornfield last summer. Kessler was awarded a three-year grant to work with Madeline Harley at the Micromorphology Unit at Kew. The remarkable shapes of pollen grains reveal important diagnostic features of plants used by sci...

Biomass was almost always greater in the first-generation offspring of crosses involving foreign material, but declined in the second generation. Mortality was higher in both generations. Seed weight, like biomass, was generally higher in the first generation and lower in the second generation of foreign crosses. So it seems that, in the long term, the introduction of foreign genes into these w...

Article 23.1 of the Code (Turland & al. in Regnum Veg. 159. 2018) rules that a specific epithet may have one three forms: “an adjective, noun genitive, or word apposition”. Of these three, “a apposition” is likely to be least clear modern reader, partly because declining familiarity with Latin among botanists, but also they often do not stand out as being this category. Upon taking closer look,...
