Dear Arlan,

This is good news! Please send me a jpeg/photo of a leaf of the plant in
Also, check my 'key' below, as some/most of the plants that grew from seed
labeled as P. adamantinum and P. saxicolum grew to be 'something' close to
P. bipinnatifidum/'selloum', but are deff. NOT P. adamantinium or P.
saxicolum! I just received a photo of one such plant, and I will forward
it to you after this.
Also check my 'key' (below)---- in P. adamantinum, the distance from the
BOTTOM of the sinuses (divisions) when measured to the mid rib DECREASES as
you measure them from the tip of the anterior division up towards the
petiole juncture, while exactly the OPPOSITE is true of any P.
bipinnatifidium-type plant. Check and tell me what you see in YOUR plant
ex: Brian Williams!
Bear in mind that we should EXPECT the plants grown for seed of P.
bipinnatifidium to vary from each other, and especially when compared to any
plant of P. bipinnatifidium in the U.S.A., the reasoning being that
presumably ALL P. bipinnatifidium/'selloum' here in the U.S.A. are out of
tissue culture, and so are clones of one another, and so will show little or
no differences to each other. The plants from seed SHOULD show differences
as they are NOT genitically alike!

The Best,

Julius Boos
