Photographs Needed!

Images on the Parasitic Plant Connection web site generally fall into one of four categories:

1. Color photographs of living plants. These are the most desirable because a good photograph is "worth a thousand words."

2. Color photographs of herbarium specimens. These can show a number of diagnostic taxonomic features and are thus "second best" to a photo of the living plant itself. Lost are flower color, aspect of the leaves, etc.

3. Color paintings. In some cases (e.g. the extinct mistletoe Trilepidea, Loranthaceae), all that exists for this taxon is a painting, hence it is used.

3. Line art (black and white) . I have generally used line art of a taxon only if 1-3 above are not available. In terms of taxonomic value, they can be extremely useful because diagnostic taxonomic features can be clearly shown. See for example Opiliaceae.

Given the above, the Parasitic Plant Connection needs your help. For the parasitic plant genera listed below, there are currently no color photographs of living plants available through this web site. In some cases, a photograph of an herbarium specimen is available and is so indicated. I routinely conduct Google image searches and usually obtain no "hits" when the generic name is entered. In some cases, this is because the plant is extremely rare (and possibly extinct) and may never have been photographed (e.g. Thaumasianthes, Loranthaceae). In other cases, photographs may exist but are housed in private collections that are not indexed on the WWWeb. For my personal use, I keep a listing of Botanical Image Databases that I check routinely for photographs of parasitic plants. If you know of other good web sites that could be added, please let me know.

Here are the photographic statistics. From my count, there are 264 genera of parasitic flowering plants (ca. 4450 species). This does not include the autotrophic members of Santalales (Erythropalaceae, Strombosiaceae, Coulaceae). Currently there are photographs present on the Parasitic Plant Connection for 245 genera (92%), thus leaving 25 without photographs (listed below). In my view, it is important to have photographs of these plants to increase public awareness of their beauty and unique features, thus promoting their conservation.

If you have photos of any of these genera that you are willing to share, or know of someone to contact to obtain such a photo, please let me know (DLN).
