Notices for Users of the Albums

1. New Albums and some changes

 

The latest Albums on genera of South African plants added to the Operation Wildflower Site are the ones on Cyrtanthus, Dicoma and Strumaria. This means that photos and stories of plants belonging to these genera already on the Site, together with some new ones, have been moved from the more general Albums called Bulbs and Herbs respectively 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 220 such genera Albums. The biggest ones (most photos) belong to the genera Crassula, Euphorbia, Pelargonium, Aloe and Erica. Keep watching, more will be added. If there is no genus Album yet on the plant you are looking for, check under Types, the grouping that the Site was started off with, accessible via the pictured items shown on the right. The Search Box may yield more, for plants and related material are also shown in Albums on Habitat, Regions and Parks and Gardens.

 

In order to access items on a plant of interest, enter its botanical name in the Search Box. Entering other words or names will access what is contained in the Albums database. The latest Regions Album is the one on Nature's Valley and the latest Parks and Gardens Album is on Tietiesbaai also known as the Cape Columbine Nature Reserve.

3. Reduced Mobile Site for Cell Phone Users

 

Operation Wildflower now also offers a reduced Mobile Site for cell phone use that only presents the Albums contents. This is aimed at overcoming display difficulties on some of the mobile devices in use for quick reference. The reduction found in the Mobile Site doesn't affect the full set of photos and stories of Operation Wildflower, only in diminishing the Site's secondary details that may make it hard to access the items on a small screen.

 

It is best to use the normal or full Operation Wildflower Site on computers, iPads and devices with bigger screens, as well as those that present unimpaired display of full details and access to all material on offer.
