This subsection is related to subsect. Clematis, differing in its 6-sepalled flower andsepals with hairs 1.6-3 mm long.

本亚组与钝萼铁线莲亚组接近，但花具6枚萼片，萼片的毛较长(1.6-3 mm)而不同。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
