Sorry!
1.
I see what I would call a duplicate, a generic entry for Chinese cabbage with no cultivar name:
Brassica rapa pekinensis and <- - - - - - suggest deleting thhis one
Brassica rapa var. pekinensis
The second one is, I think, a "more better" name, and has several nice common names listed instead of any specific cultivar name (we have are pages of Chinese Cabbage cultivar names).
2.
I also see MANY entries (probably non-duplicates) with the "rapa" left out and also the "var." missing, as if "pekinensis" were a species name.
Maybe that was common some years ago, but I think it is "not correct now", whatever "correct" means, when it keeps changing.
example:
Chinese Cabbage (Brassica pekinensis 'Qing Summer No.1')
should be:
Chinese Cabbage (Brassica rapa var. pekinensis 'Qing Summer No.1')
I would be happy to chnage all those by adding the "rapa var.", but shouldn't get acorns for anything that easy!
But I won't do it unless someone is sure there's no obscure reason to use "pekinensis" as a species name.
I would bet a quarter-ounce of seed that any "B. rapa" will cross-polinate any other "B. rapa"
Who knew that any annual vegetables were rappers!
3. just curious -
I see that we use
Brassica rapa var. pekinensis
instead of
Brassica rapa Pekinensis Group.
I've seen it done both ways in different places: is one newer, or more geeky, or preferable? Why?
