Chaenostoma hispidum flower tubes

The long tube of a Chaenostoma hispidum flower is funnel-shaped in slightly more than its yellow upper third, pale and cylindrical in the lower part. The yellow part of the tube is faintly ridged. The tube becomes 8 mm to 12 mm long.

The narrow sepals reach up around the tube nearly half of its length, positioned near it but not adhering to it in the photo. The calyx is green or purple, always hairy.

The bristly nature of the hairs in picture, at least some of them glandular, features in the plant’s common name of bristly skunk bush (Privett and Lutzeyer, 2010; Bond and Goldblatt, 1984; iNaturalist; http://pza.sanbi.org).
