220 MR. E. W. BlNiVEY ON ORGANS OF FRUCTIFICATION 



teen to twenty sets of verticillate leaflets, and was about 

 nine-tenths of an inch in length. In form and size the 

 leaf resembles the cones of Calamodendron commune, 

 whose foliage is unknown, so far as my knowledge 

 extends. 



Fig. 2. Plate VI. represents a fruit-stalk found by myself 

 at Ewood Bridge. It consists of a stout rachis, indistinctly 

 ribbed and furrowed, four inches in length, and exhibiting 

 twelve nodes, at which strongly marked knots appear. 

 From these knots the whorls of fruit-cones or spikes pro- 

 ceeded, covered with imbricated scales. The number of 

 receptacles for containing spores varied from fourteen to 

 eighteen in each cone. In the specimen not more than 

 four cones can be seen coming from one node ; but if all 

 had been preserved and exposed, probably they were from 

 twelve to sixteen in number. At the base of the cone, in 

 several instances, whorls of delicate leaves (Asterophyllites) 

 are visible. In the highest cone on the left-hand side of 

 the stem they may be more distinctly seen than at the 

 lower portions in the other cones. 



The annexed woodcut"^ is a representation of 

 one of the cones or spikes, covered with imbri- 

 cated scales, at the terminal part of a branch. It 

 is evidently of the same kind as those previously 

 described as proceeding from the nodes, and is 

 most probably the terminal portion of a panicle 

 of fruit- cones. 



The fruit-stalks, cones, and leaves above de- 

 scribed are found all compressed together, with 

 scarcely any admixture of the remains of other 

 plants, except the long simple leaves of Astero- "^^^ 

 phyllites, stems of Calamites, and a few leaflets ^^ 



* The woodcut is slightly enlarged in length from the original, and nearly 

 double its diameter. The size of the specimen is about that of one of the 

 smaller figured in Plate YI. fig. 2.
