Most of the fossil material is in the form of isolated scraps which are described if only to give a stimulus to subsequent collectors. Monocotyledons. Stems.—Stems of a small monocotyledon are abundant in local areas in the rock. These stems are of two kinds, but as they have been found in attachment they are from the same plant and represent rhizomes and aerial axes respectively. Rhizomes.—These are cylindrical structures as much as 2-3 cm. long and 2-5-3-5 mm. in diameter: a few reach 5-5 mm. Most are unbranched. They have a characteristic appearance due to furrows on the surface which run both longitudinally and horizontally and divide the surface into rectangular areas which have the longer axis horizontal. In the younger portions scale leaves arise from the.
