Their seeds, which are small, probably grew in heads or clusters, and in pairs, not adherent to the calyx. They were probably seeds of a dico- tyledonous plant, but of what kind it is impos- sible to form a conjecture. Lepidostrodus. Oblong bodies (5, c, cut 230,) are of frequent occurrence along with the fragments of the lepidodendron and ulodendron. They are evidently seed vessels, somewhat similar to the cones of the coniferse, and have been conjectured to be the cones of the lepidodendrons and ulo- dendrons. Although found plentifully associ- ated with the stems of these fossils, no specimen has occurred where they were actually attached. Two or three species have been distinguished. L. ornatns, I. variabilis, and I. comosus. They consist of a conical axis, around which a quan- tity of scales are compactly imbricated, and pointing from the base upwards, (cut 230, fig. c.) Sometimes, however, in specimens, (cut 231, fig. c,) they are apparently turned down- wards, which is perhaps owing to their having been forcibly compressed from above downwards. The specimens vary much according to their age. Lepidoph/llum. (Fig. d, cut 230.) These lance- olate figures appear to be tSie leaflets of the lepi- Ulodendron. The plants to wlueli the fossil fragments so frequently found in the coal strata must have belonged, and to which the name of ulodendron has been given, must have borne a near resemblance to the lepidodendron ; indeed, by some, the former are supposed to be only older specimens of the latter, with their areolse altered by age and the
