Which plant genus has the most species? Which has the biggest?

asked in plant genus, most, biggest



P-Kasso answers:

Stab in the dark here, Xolo.

I'd suggest grasses. Does that include rice? If so, then even bigger.

Just a guess as I have to go out now. Saturday night looms invitingly!

I can't find anything with more than the 25,000 - 30,000 species of orchid.

". The orchids (Orchidaceae) have more species than any other family of flowering plants with 25,000-35,000 species recognized, mostly in the tropics. Although some species do remain to be discovered, the difference between these estimates is mostly one of different taxonomic concepts"

I'm not sure what you mean by 'which has the biggest? Do you mean the biggest specimen?


Supplement from 02/07/2009 07:48pm:

Sticking with my original answer, the largest orchid is Grammatophyllum speciosum

The dramatic six-foot flower spikes emerge from the pseudobulb bases. Over a two-month period, each prodigious spike may produce a hundred large, waxy flowers, four inches in diameter and mottled reddish brown and butterscotch yellow.

As a matterer of interest:

Largest flower of all are the Parasite stinking corpse lily (Rafflesia arnoldii), which can grow to 91 cm 3ft wide, 1.9 cm ¾in thick and weigh up to 7 kg 15 lb. The plants attach themselves to cissus vines in the jungles of South-east asia and, true to name have an extremely offensive scent.
