The dorsal side of each leaf is, however, at its upper end hollowed out like a cowl or a helmet, and forms a cupola as is shown in fig. 21J and 212. The orifice or entrance into the utricle is consequently covered over and is reduced to a slit or hole under the hood. The lamina is trans- formed into a lobe, which in Sarracenia variolaris is small and roofs over the orifice of the utricle, and in Darlingtonia is shaped like the tail of a fish, and hangs down in front of the aperture. The lower part of the utricle is of a uniform green colour, but the upper part ( the cupola and lobe-like appendage) has red ribs and veins, and here and there is quite purple. Between the veins the.
