When I enter the term "nasturtium" in the search field only a few entries come up. When I enter "Tropaeolum majus" many more come up. Does it always filter this way and I just didn't notice it before?
"Nasturtium"
"Tropaeolum majus"

My concern would be that persons browsing in this area may not know (or wish to search it out) the correct spelling of "Tropaeolum majus" and may miss the major part of this plant's listing. (I almost proposed a new entry for the one I'm working with right now.)

The former link is the browse by genus - showing all the plants in the Nasturtium genus and nothing else.

The second link is going to a search which is searching all the texts, including common names, latin names, cultivars and synonyms. This is why it has so many matches.

Thanks for the explanation, Dave. I guess I just hadn't noticed it before today.
