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.

Naturalization Papers for Invader Plants?

Legend has it that cosmos and a number of other alien plants such as blackjack and khakibos arrived in this country during the Boer War.  The British imported fodder for their horses from South America and of course this baled grass was full of the seeds of opportunistic plants. The troops carried this fodder in hay nets hanging from their horses and as they rode about the country the seeds were shaken out and took root where ever they fell! With no natural enemies they flourished.

Some are highly invasive and impact directly on our indigenous plants, while others, like cosmos, just grow where they can and give us a visual treat once a year.

Of course, a lot of our most dangerous invasive alien plants are just that, because they have eye-catching forms or stunning flowers. They are brought into the country as garden plants and soon escape into the surrounding areas. We all have our views on what we should cultivate in our gardens and most suburban gardens are a mixture of indigenous and alien plants.

Horticulturalists and botanists talk about naturalised and non-invasive alien plants. The caster-oil plant, Ricinus communis, is a declared weed and invasive alien. Johan Binneman of the Department of Archaeology at the Albany Museum in Grahamstown discovered caster-oil seeds during excavations in several Eastern Cape archaeological sites that date back 10 000 years. This plant was used by the San and KhoiSan for medicinal purposes!  How long does a plant have to be resident before it is given naturalization papers?
