A Taraxacum comparison

Опис:

The native Taraxacum aristum (mountain dandelion - left) and the introduced Taraxacum officinale (common dandelion - right) flowerheads placed next to each other. Plants growing at the nursery of the Royal Tasmanian Botanical Gardens.Taraxacum officinale is known to be apomictic (ie the flowers do not fertilise and the seeds produced are vegetative clones of the parent plant). The reproductive system of Taraxacum aristum is not clear. Flowerheads only last for about two days, only seem to open in sunny weather and pollinators have rarely been observed. Despite this seed production is prolific.
