When the newly grown style hairs are still flattened on their Clematis villosa subsp. stanleyi flowerhead, the fruits at the base of the wiry styles are still green. This is like newborn hairy or feathery babies that need to dry still.
The fulness of time brings growth and sometimes ripening. Once the dry fruits let go of their grip on the mother body below, the style hairs will be fully fluffed, prepared for the breeze to carry them away to new lives (Germishuizen and Clarke, 2003; Leistner, (Ed.), 2000; Van Wyk and Malan, 1997; iNaturalist; https://www.zimbabweflora.co.zw).
