Dear Hubert,
Thanks for your prompt reply regarding "Anthurium " photos few days ago.. Today, I just found this unknown plant is called" Rape blossom, Celery cabbage", or " Brassica campestris" -- academic name. This little yellow flower can be seen easily in Spring of most rice fields, from where I come from, Taiwan. It is also easily can be found in Japan in Spring too. It is one kind of (oil-seed) rape. Farmers plant it as natural fertilizer. I am not a professional photographer, neither botanist or herbalist, but I do really enjoy those nice photos in your photo albums too. You really open my horizon!!
From: Jimmy, Taiwan
