I believe mass has had plenty experience with this as seen in such a pic....
Ceph Leaf Pullings
I just took this picture, the result of a leaf pulling from a few months ago:
Very Nice Pics Everyone!!! I can't believe it was rooted in perlite... what was it's conditions? Humidity, temperature, and light if available?
Very Promising! I rooted these cuttings in chopped LFS in a completely closed Glad container.
Plus some Drosera Regia "Big Easy" water cuttings and one Cephalotus "Big Boy" cutting.
Again.. the yellow leaves can be tossed. Those are no good.
My method is to take the cutting and immediately place it into one of these propagation cups. Just a small size dixie cup works.. I cram it full of live LFS, stick the cut end of the leaf way down in there so the top of the leaf is barely showing, and keep it moist at all times. I leave the cups around my HL GH in misc. places.. and after 4-6 months.. WAHLAH! I've also had great success with just sticking leaf cuttings into random drosera pots. Silica and peat, in a high humidity tank has been working as well.
Wow like a professional. The 6 yellow leaves I started for some reason have calluses. Does the whole leaf have to be yellow for it to not root? In the second picture, the leaf on the far left is sending up a pitcher.
