  Philodendron DNA
From: "zonneveld" zonneveld at rulbim.leidenuniv.nl> on 2002.01.23 at 07:04:34(8043)
Joe Wright was so kind to send me 5 leaf samples, 4 of
Philodendron selloum and the fifth ( which one? ) of P. (bi)
pinnatafidum.
Unfortunately the leaves were dry on arrival due to the paper in the
same sachet. I imbibed them in water and tried anyway The results
are therefore not very good, also because the values are rather low
but:
no2 = 3.64 picogram and no 5=3.68 pg so seem identical.
no1 = 4.63 pg and no 3=4.88 pg both probably the same species.
no 4 = 5.38 pg So we might have three! species unless ploidy is
involved in that case no4 is a triploid of no1/5.( but see the caveat
above). Maybe I try again tomoorow afeter a nifgt in water.
Could you comment on the results Joe ( or others) as I dont know
much about Philodendrons

All samples are believerd to be identical as P. selloum with exception to N0.3. All are self heading and come from private well disbursed gardens. N0. 3 while similar is distinctly vining. Now is a good time for others to input info re: heading/vining P. selloums Philo No. 3 was id'd as bipinnataphyllum but after discussions here and it' being synonymous I suspect it might be P. pinnatafidum. I will be glad to resubmit samples w/o paper id's inside. I apologize for the oversight. Joe
