Matricaria L. (シカギク) Orosyagiku (オロシャギク, 露西亜菊) / Koshikagiku (コシカギク, 小鹿菊), pineapple weed (rayless chamomile) Meaning: 'Orosya' and 'Koshika' mean 'Russia'. 'Giku (kiku)' means 'Chrysanthemum'. Lifeform: annual forb < 30 cm high Distribution: north America and northeast Asia (exotic to Japan)

Hatibat: ruderal as a weed (雑草) Flavor: like a melon, water melon, or pineapple (I want to say the smell is like a pineapple) Along roads in the campus of Hokkaido University, we can see a lot of pineapple weed. You may see this species in a field trip of my lecture, HUSTEP (Plants and Plant communities in Japan, flora list).
