Cichorieae
The Cichorieae (also called Lactuceae) are a tribe in the plant family Asteraceae that includes 93 genera, more than 1,600 sexually reproductive species and more than 7,000 apomictic species. They are found primarily in temperate regions of the Eastern Hemisphere. Cichorieae all have milky latex and flowerheads that only contain one type of floret. The genera '' Gundelia'' and '' Warionia'' only have disk florets, while all other genera only have ligulate florets. The genera that contain most species are ''Taraxacum'' (Crepidinae subtribe) with about 1,600 apomictic species, '' Hieracium'' with about 770 sexually reproducing and 5,200 apomictic species, and '' Pilosella'' with 110 sexually reproducing and 700 apomictic species (both Hieraciinae). Well-known members include lettuce, chicory, dandelion, and salsify. Description Most species are herbaceous, perennial, short-lived or annual plants, rarely subshrubs, shrubs or vines. All Cichorieae-species have latex canals in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gundelia
''Gundelia'' or tumble thistle is a low to high (20–100 cm) thistle-like Perennial plant, perennial herbaceous plant with latex, spiny compound inflorescences, reminiscent of teasles and eryngos, that contain cream, yellow, greenish, pink, purple or redish-purple Asteraceae#Floral heads, disk florets. It is assigned to the family Asteraceae. Flowers can be found from February to May. The stems of this plant dry-out when the seeds are ripe and break free from the underground root, and are then blown away like a tumbleweed, thus spreading the seeds effectively over large areas with little standing vegetation. This plant is native to the eastern Mediterranean and the Middle-East. Opinions differ about the number of species in ''Gundelia''. Sometimes the genus is regarded Monotypic taxon, monotypic, ''Gundelia tournefortii'' being a species with a large variability, but other authors distinguish up to #Number of species, nine species, differing in floret color and pubescence.
