endangered species

Hi Linda
Interestingly, according to Wikipedia,
The species violets are endangered ...

"Saintpaulias, commonly known as African violets, are a genus of 6�20 species of herbaceous perennial flowering plants in the family Gesneriaceae, native to Tanzania and adjacent southeastern Kenya in eastern tropical Africa. Typically the African violet is a common household indoor plant but can also be an outdoor plant. Several of the species and subspecies are endangered, and many more are threatened, due to their native cloud forest habitats being cleared for agriculture."

This year, Optimara is offering at least one species
plant. Other growers are, also, I just can't recall which
ones off-hand.

    Joanne,

    Species are easier to find these days than they used to be due to increased interest, I would assume. I have a S. ionantha which is the species from which most of our modern hybrids come. This species is also the first AV I ever grew.

    Violets are being re-classified and renamed lately by those in charge of such things. Most of the named species are now thought to be sub-species of S. ionantha. The lumpers and splitters continue to make nomenclature difficult for us!

    Violet Gallery has a great selection of species. Most of them are extremely tough and easy. I like Saintpaulia tongwensis - pattern on the leaves is absolutely cool - and S.orbicularis purpurea - very floriferous with multitude of small intense royal purple blue blossoms.

    Here is some information that I thought might be interesting. The former species status of many has been reclassified into sub-species of S. ionantha. I believe this results from DNA testing on these plants which shows them to be sub-species rather than species in their own right. (Please tell me that I am not the only one who finds this stuff fascinating!!!)

    Old name vs. current name

    Saintpaulia amaniensis = S. ionantha ssp. grotei
    Saintpaulia brevipilosa = S. ionantha ssp. velutina
    Saintpaulia confusa = S. ionantha ssp. grotei
    Saintpaulia difficilis = S. ionantha ssp. grotei
    Saintpaulia diplotricha = S. ionantha ssp. ionantha var. diplotricha
    Saintpaulia grandifolia = S. ionantha ssp. grandifolia
    Saintpaulia grotei = S. ionantha ssp. grotei
    Saintpaulia intermedia = S. ionantha ssp. pendula
    Saintpaulia magungensis = S. ionantha ssp. grotei
    Saintpaulia magungensis var. minima = S. ionantha ssp. grotei
    Saintpaulia magungensis var. occidentalis = S. ionantha ssp. occidentalis
    Saintpaulia nitida = S. ionantha ssp. nitida
    Saintpaulia orbicularis = S. ionantha ssp. orbicularis
    Saintpaulia pendula = S. ionantha ssp. pendula
    Saintpaulia pendula var. kizarae = S. ionantha ssp. pendula
    Saintpaulia rupicola = S. ionantha ssp. rupicola
    Saintpaulia tongwensis = S. ionantha ssp. ionantha var. ionantha
    Saintpaulia velutina = S. ionantha ssp. velutina

    The genus is most closely related to Streptocarpus, with recent phylogenetic studies suggesting it has evolved directly from subgenus Streptocarpella.

    And we think Dave is confusing? Try taxonomists - every 20 years everything is reshuffled, new genera created, old ones collapsed - species renamed - and 20 years later - the process is repeated, retired genera revived, species are re-renamed. Now we have a new DNA information that causes the workover. But I suspect that is i a change of generations. Old esteemed professors retire - and new blood comes with a new vision.

    So far - even Streptocarpella is supposed to be the closest one to AVs - nobody produced an intergeneric cross between these two. And it means tat they are not that close.

    I think lumping and splitting is how the botanists keep their jobs.

    Dave,

    Your lawyers are budding?

    I have a double bloomer ... seems he likes to double charge ... I keep saying there aren't enough hours in a day

    dave (getting ready to turn the clocks back ... zzz)

    another chance for him to double bill
