THE FLORA OF THE COAL FORMATION. 459 its being covered with Spirorbis, I think it must either have been of more aquatic liabit than most of the other plants of the Coal forma- tion, or that its leaves must have been very durable. While the leaves are abundant, the stems are very rare. I infer that they were usually low and succulent. Much of the tissue found in the coal, which I have called "epidermal," probably belongs to leaves of Cordaites (Fig. 172), In the Upper Coal formation there is a second species, distinguished by its simple and uniform venation. This I have named C. simplex. 4. Sporangites.âTo avoid the confusion which envelopes the clas- sification of Carpolites, I have used the above name for rounded spore- cases of Lepidodcndron and allied plants, which are very frequent in the coal. A smooth round species like a mustard-seed is exces- sively abundant in the Lower Carboniferous at Horton, and probably belongs to Lepidodendron corriigatum, with which it is associated. A species covered with papilla?, *Si. papillala, constitutes nearly the whole of some layers in coal 12, group xix. of the Joggins section. I have no indication as to the plant to which it may belong, except that it is associated with Cordaites (Fig. 173, L). Fruits, Flowers, etc. 1. Antholithes, Brongn.âSpikes of fruits protected by bracts, and which I believe to have been produced by Sigillarioid trees (Fig. 173, A, B, C). 2. Trigonocarpiim, Brongn.âNut-like fruits, often three or six angled; with a structure akin to those of Pines and Cycads. I believe most of them to have belonged to Sigillaria, some possibly to conifers (Fig. 173, D, E, F, and Fig. 174). 3. Rhabdocarpits, Gocppert and Brongn.âOval fruits with striated
