the inflorescence of a jack-in-the-pulpit seen from the side. this unusual structure consists of a leaf-like sheath (the spathe) which wraps around and folds over the top of a flower-bearing column (the spadix). the spathe forms a tube less than two fingers in diameter and half a handspan in height; at the top in the front it curls down forming a collar, but in the back it becomes a long flap that curves up and over, drooping down on front side. the outside of the spathe is light green striped with white. on the inside, it is purple striped with white. the rounded top of the spadix is visible between the collar and hood of the spathe.
looking within the spathe to see the spadix within. the inner surface of the spathe is striped with purple and white. the spadix is a column, rounded (and blurry...) at the top. its upper portion is purple, but near its base it narrows and is white. the white section is lined with knobby purple and white flowers with neither calyx nor corolla.
a jack-in-the-pulpit standing in front of a big, mossy tree trunk, standing nearly knee-high above the leaf little on the forest floor. its reddish stem is pretty thick at the base. two leaves branch off the base in opposite directs, each around 45° off the main stem. the leaves' stems and the main stem are still somewhat stout even above the split. the green leaves are trifoliate with large ovate leaflets, one middle leaflet and two perpendicular lateral leaflets forming a T. the main stem terminates in an inflorescence with a green, white, and purple striped spathe wrapped around and folding loosely over the top of a cylindrical purple spadix. the flowers are tiny and hidden at the base of the spadix within the spathe.
