Development of leaf shape and vein homologies in five species of the genus Ipomoea (Convolvulaceae)
Angiosperm leaves are extremely variable in form while predominantly maintaining the function of the primary photosynthetic organ of the plant. Changes in leaf form can result from myriad physiological processes which may be influenced by ecology, physical stimuli, phylogeny, or other factors. In studying the development of divergent leaf forms among closely related species, conserved morpholog...
متن کاملAlkaloidal components in the poisonous plant, Ipomoea carnea (Convolvulaceae).
Natural intoxication of livestock by the ingestion of Ipomoea carnea (Convolvulaceae) sometimes occurs in tropical regions of the world. Polyhydroxylated alkaloids were isolated from the leaves, flowers, and seeds of the poisonous plant and characterized. Chromatographic separation of the leaf extract resulted in the isolation of swainsonine (1), 2-epi-lentiginosine (2), calystegines B(1) (3), ...
متن کاملNew species of Ipomoea (Convolvulaceae) from South America
The importance of discovering, describing and cataloguing poorly known species in herbarium collections is discussed. It is a spur to efforts at rediscovery and consequent conservation efforts. The problems faced in describing species from limited material are discussed and our methods and criteria in making a decision are described. Prospects for future novelties are briefly assessed. Fifteen ...
متن کاملIntroduction of seed and capsule micromorphological features of the genus Scrophularia (Scrophulariaceae) in Iran
In the present study, seed surface ornamentations in 31 species (34 populations) and the capsule surface sculpturing in five species of the genus Scrophularia L. distributed in Iran were examined using Scanning Electronic Microscopy. Based on the published seed surface terminologies, all examined seeds show the reticulate pattern with scalariform inner ornamentations. However, there is enough b...
متن کاملChromosome studies in the genus Jatropha L
The inflorescences of ten species of the genus Jatropha were fixed in Cornoy’s fluid (6:3:1). Acetocarmine stain (2%) was used for staining the pollen mother cells. Seven species exhibited 11 bivalents and 2n =22 and x=11. But the two other species, J.villosa var. villosa and J.villosa var. ramnadensis showed only 10 bivalents and 2n number of 20 chromosomes and x=10. The study concluded the oc...
