I'll interrupt Bryant's series on colours in plants (which should conclude on Monday) with another photo contribution from James Gaither (J.G. in S.F.@Flickr). Thanks as always for the excellent photographs (original image | via Botany Photo of the Day Submissions Flickr Pool).
As with many species from South Africa, the South African National Biodiversity Institute's PlantZAfrica site has some of the best information available, so instead of repeating from their site, I'll highly recommend this page containing information on name derivation, habitat and conservation status: Tritonia crocata. The one thing I will quote from their site is the meaning of the name Tritonia, as it is important below: "[from] the Latin word triton, a weather vane, due to the variable orientation of the stamens in some species". For a survey of Tritonia floral diversity, the Pacific Bulb Society Wiki has a great set of photographs for this genus: Tritonia.
If searching for more information on Tritonia online, your results may include information on some animals also named Tritonia. Since plant names are required to conform to a different international code than animal names (the International Code of Botanical Nomenclature vs. the International Code of Zoological Nomenclature), there is nothing preventing the use of the same generic names in each system (or, even, the same species name). When this occurs, the two names representing two different taxa or taxon groups are considered to be hemihomonyms. Keeping in mind that the name Tritonia is derived from triton meaning "a weather vane", one would expect some sort of appendages on these animals. Here are some photographs of the nudibranchs (sea slugs) named Tritonia: Tritonia festiva, Tritonia striata and an unnamed Tritonia species from National Geographic.
