there are several varieties of prayer
plants. i have the one that is referred to as "rabbit's foot" due to the markings on the leaves. it does not have the red lines ever. and the "foot prints" on the leaves are barely noticable on the smaller, younger leaves, and on the leaves that do not get good light (if i forget to turn it) but the older, better lit leaves have the prints almost red on them. they start out just a slightly darker green than the rest of the leaf.
the proper name for the
plant is Maranta and there is an information page here at the garden helper
prayer plant that has a picture of one like mine.
