Eudicots

The Eudicots, Eudicotidae or Eudicotyledons is a monophyletic clade o flouerin plants that haed been cried tricolpates or non-magnoliid dicots bi previous authors. The botanical terms wur introduced in 1991 bi evolutionary botanist James A. Doyle an paleobotanist Carol L. Hotton tae emphasise the later evolutionary divergence o tricolpate dicots frae earlier, less specialised, dicots. The close relationships amang flouerin plants wi tricolpate pollen grains wis initially seen in morphological studies o shared derived chairacters. Thir plants haes a distinct trait in thair pollen grains o exhibitin three colpi or grooves parallelin the polar axis. Later molecular evidence confirmed the genetic basis for the evolutionary relationships amang flouerin plants wi tricolpate pollen grains an dicotyledonous traits. The term means "true dicotyledons" as it conteens the majority o plants that hae been considered dicots an hae chairacteristics o the dicots. The term "eudicots" haes subsequently been widely adoptit in botany tae refer tae ane o the twa lairgest clades o angiosperms (constitutin ower 70% o angiosperm species), monocots bein the ither. The remainin angiosperms is whiles referred tae as basal angiosperms or paleodicots but thae terms hinnae been widely or consistently adoptit as thay dinnae refer tae a monophyletic group.

The ither name for the eudicots is tricolpates, a name whilk refers tae the rit structur o the pollen. Members o the group hae tricolpate pollen, or fairms derived frae it. Thae pollen hae three or mair pores set in furrows cried colpi. In contrast, maist o the ither seed plants (that is the gymnosperms, the monocots an the paleodicots) produce monosulcate pollen, wi a single pore set in a differently orientit raut cried the sulcus. The name "tricolpates" is preferred bi some botanists fur tae evit confuision wi the dicots, a non-monophyletic group (Judd & Olmstead 2004).

Numerous faimiliar plants are eudicots, includin mony common fuid plants, trees, an ornamentals. Some common an faimiliar eudicots include members o the sunflower faimily lik the common dandelion, the forget-me-nae, cabbitch an ither members o its faimily, aiple, buttercup, maple an macadamie. Maist leafy trees o mid-latitudes belang eudicots an aa, wi notable exceptions bein magnolies an tulip trees whilk belang tae magnoliids, an Ginkgo biloba whilk isnae an angiosperm.

The name "eudicots" (plural) is uised in the APG seestem, o 1998, an APG II seestem, o 2003, for classification o angiosperms. It is applee'd tae a clade, a monophyletic group, that includes maist o the (umwhile) dicots.
