Cypsela of Taraxacum aristum cleaned to remove pappus and leave the achenes. Species shows interesting variation in fruit colour which is consistent within a flowerhead and possibly consistent for the individual. Fruit colour also appears to match that of the parent plant.

2012-08-13 Vienna, district X./ Lower Austria, district Wien-UmgebungGerman name: Lss-Lwenzahn (fruchtend)Very typical for this species are the great number of flowering (and fruiting) stems, while "ordinary" T. officinale (agg.) only grows one stem per rosetta. Also, rosetta leaves of this one are quite distinct and easily recognisable.This habitat here is the southerly exposed side of S1 motorway, it has been seeded by biologist Mr Biskup with seeds of dry meadow plants from local production - so even though this is not quite a natural occurrence it is almost so.

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.
