Notices for Users of the Albums

1. New Albums and some changes

 

The latest genera Albums added to the Operation Wildflower Site are the ones on Bauhinia, Cleretum and Manulea. This means that photos and stories of plants belonging to these genera already on the Site have been moved from the more general Albums called Trees, Mesembs and Herbs into their own new Albums under Genera. 

 

There is a genus Album in every case where enough material has been accumulated to warrant a stand-alone grouping of photos and stories. There are now more than 160 such Albums on genera of South African plants. The biggest ones (most photos) belong to the genera Crassula, Euphorbia, Pelargonium and Aloe. Keep watching, more will be added! If there is no genus Album yet on the plant you are looking for, check under Types or the Search Box.

 

In order to access all items on a plant of interest, the Search Box should be used, entering the botanical name of the plant. Most photos and stories on a particular plant are likely to be posted under Genera, (or if there are only few of them, in the conglomerate categories under Types). Habitat, Regions or Parks and Gardens may also contain some material on a species searched for, showing in the list generated when using the Search Box. The latest Parks and Gardens Album is the one on the Quiver Tree Forest.
