Pollen Morphology of Some Turkish Crocus L. (iridaceae) Species
The genus Crocus L. (Iridaceae) comprises about 80 species distributed mainly in the Mediterranean region. It is widely dispersed in Turkey; at present about 67 taxa (including subspecies and varieties) are recognized there (Mathew, 1984, 1988, 1995, 2000; Kerndorff and Pasche, 2003, 2004).

متن کاملWould Sacaca, Croton cajucara Benth (Euphorbiaceae) be an hepatotoxic plant like Germander, Teucrium chamaedrys L. (Labiatae)? Será a Sacaca, Croton cajucara Benth (Euphorbiaceae) uma planta hepatotóxica semelhante à Germander, Teucrium chamaedrys L. (Labiatae)?
Clinical and experimental studies have consistently incriminated the medicinal plant germander (Teucrium chamaedrys L.) in epidemic and sporadic cases of liver diseases. The sacaca (Croton cajucara Benth), a common plant in Brazilian Amazon region also comes being incriminated in similar clinical cases. Of both plants were isolated diterpenoid coumpounds with similar chemical structures. Key-wo...
متن کاملIn vitro antioxidant activity of some Teucrium species (Lamiaceae).
The chemical composition and antioxidant activity of different extracts (diethyl ether, ethyl acetate and n-butanol) obtained from Teucrium species (T. chamaedrys, T. montanum, T. polium) were investigated in this work. Phytochemical screening of the plant extracts proved the presence of flavonoids luteolin, apigenin and/or diosmetin. The chemical composition of extracts was evaluated by HPLC a...
متن کاملRelationship between pollen morphology and chromosome numbers in Brazilian species of Lippia L. (Verbenaceae).
The pollen morphology and exine structure of 17 species of Lippia L. were investigated in this work using light and scanning electron microscopy. Among the species studied, 14 showed tricolporate pollen grains, two had tri- and tetracolporate pollen grains and a single species exhibited, only tetracolporate pollen. The amb ranged from triangular to square, and the shape varied from oblate-spher...
