one more sp with blue fruits. very nice


Thanks … for the Nepali names of the plant.
The blue colour of the fruit is pleasure to eyes. But, I am curious and naive … are those fruits or buds ?


Thank you … Never seen flowers.


did I jump the gun and think it was fruit? I looked at it again. may  be fruit. may be bud.
either some fruit can have those protective round covers as in Chalta ir Dillenia indica fruits.
any way any follow up would be nice … if possible


Thanks … you are right – they are fruits.
I was not having sufficient time to google then.
Now I did a search. They are fruits, and also learnt that the whole structure is infructescence (an aggregate fruit, or a fruiting head).


Never seen flower of this plant but enclosing flower image from net. 2048 × 1536


Thanks … for showing this plant, when I had seen it in Gori Valley area (in October), it was having fruits only, probably it flowers in August… I could never see it again..
