Thank you,Gurcharanji, these berries are different looking... these are separate, the bunch seems pointing towards the earth... as opposed to the poison sumac berry bunches seen in north america... not sure if it occurs in SF where you are right ow but if you go to the mountains or into oregon I have seen them... since they are weeds never took time to really photograph them... but being a keen botanist I am sure you'll spot them... very soon the leaves would change colors too... their berries individually are quite small... but tightly packed.. almost as tightly as millet or jowar is packed...
still with the difference in berries... the leaves /twigs/juice behaved like a rhus anyway... family of allergenic plants... Lesson to learn. I did.
