Surrounding the column are three sepal and three petals,sometimes easily recognizable as such,often distorted into gorgeous,weird,but always functional shapes.

请问

1.“sometimes easily recognizable as such,often distorted into gorgeous,weird,but always functional shapes.”这个是三个并列的补语吗？还是该怎么分析？

2."sometimes easily recognizable as such"的such指的是什么？指的是“Surrounding the column are three sepal and three petals”还是指“often distorted into gorgeous,weird,but always functional shapes”？
