Comments (4)Isn't Audrey 2 a cross between a VFT and a butterwort? Anyways, I am no Botanist, nor a Taxonomist, but I feel that classification of carnivorous plants, as genus and species, has been muddled. The experts can't agree upon how many legitimate species there are, within a given genus, and its seems that anything I've ever learned in Biology, associated with the concept of speciation (ontogeny & recapitulation)no longer strictly applies. I'm also concerned that the classification has mixed analogy (filling a similar niche) with homology (structure) and whether certain plants, displaying similar characteristics, but very different geographical locations, are truly related, or as related as what has been deemed. Personally, I think there are a lot fewer true species out there, based upon what has the ability to mate with another, producing viable offspring. But that is conjecture on my part! And I wonder what these plants were like in Gondwanaland. Personally, I think that hybridizing different sundews with VFT's may be too much of a genetic stretch, but maybe attempting this with the Aldrovanda may be more workable.

Comments (264)I have a bud that just broke on one of the hybrids, from the Archeri x White Angel, it is dark purple, very very tiny flowers, maybe less than 1inch … the others have buds but nothing else has broken open yet. I’m happy to see that white parents produced color, archeri is blood red so I’m very interested now to see the open flower some have crazy leaves too, one of the berigated ones made it, the leaves look really unhealthy...See MoreDianthus x allwoodii Helen x D. knappii
Comments (4)The cross of white Dianthus plumarius x D. knappii has been made in New Zealand and was successful. D. plumarius is a hexaploid (6n). The researchers found that D. knappii produces unreduced gametes, that is some of its pollen or ovules instead of having n chromosomes have 2n chromosomes. The chromosomes of the seedlings were counted and some were tetraploids (3n + 1n = 4n) and some were pentaploids (3n + 2n = 5n). The seedlings from the cross with the white plumarius were pale cream-yellow with some differences in intensity. Twenty crosses were made and four seedlings produced. Because the researchers found self-pollinations in early crosses they emasculated the flowers for subsequent crosses. D. knappii was the pollen parent in all crosses. As a possible interest not all Dianthus allwoodii are hexaploid - a chromosome count of D. allwoodii 'Doris' found it to be 4n....See MoreGenealogy
Comments (24)Old Fixer, although I use the FamilySearch.org web site, and have also used the LDS Family History Library as well as a local Family History Center, I do not have a tree uploaded to their web site. So, I cannot say whether or not "just anyone" can edit information on a tree that is on their site. I will look into that, though. I do know with certainty, however, that if you have a tree on Ancestry.com, you can mark it as Private. No one can see info that is on the tree unless you send them an invitation to see it. If you add photos or images of documents, etc., to a Private tree, small thumbnails will show up when other people do a search on a name, but if anyone clicks on the thumbnail to see a larger version, they will get an error message that the tree is private. You can also have a tree on Ancestry.com that is marked as Public. When a tree is Public, anyone can see information/photos, etc., for anyone who is deceased, or presumed to be deceased (e.g., they were born in 1884 and you don't have a death date, but it's easy to see that the person would not still be alive - they'd be 130 years old this year). If the person is still living, or presumed to still be living, all anyone can see is a shadow profile of either a male's head or a female's head. For the name it would say Living Fixer, so no one can even tell what the person's first name is (this example uses "Fixer" as the surname). And, even if a tree is marked Public, no one can change anything on it, unless you invite the person to be an editor. You can invite people to just view the tree (they would be invited with a "Guest" designation); or you can give them the ability to add to the tree (they would be invited with a "Contributor" designation); or you can invite them as an "Editor" with full ability to add/change/remove information/people. People who are invited as Guests and/or Contributors can be given the ability to view living persons, but that's not the default setting. You have to deliberately give them that ability. Anyone invited as an Editor automatically can see everything....See Moreredtartan
