FEOM THE HTJTTON COLLECTION. 41 



36. — Catamites decoratus, Avtis. Very interesting specimen, shewing 

 the attachment of a stem about one inch wide to the joint of 

 another rather larger stem, from the joints of which rootlets 

 have sprung. 

 Loc. — Shale above the Bensham Seam, Jarrow. (H. C. 18). 



37. Lower portion of three stems apparently springing from 



a rhizome. 



Loc— Shale above the Bensham Seam, Jarrow. {H. C. 20). 



38. Compressed, crushed portion of lower part of stem covered 



with carbonaceous matter, stem attached to and springing 



from a rhizome. 



Loc. — Shale above the Bensham Seam, Jarrow. (H. C. 19). 



39. Portion of a broad, partly compressed stem with several 



narrow joints. On one side there is a tapering stem springing 

 from the tubercle of one of the joints ; the ribs of the inter- 

 nodes have a corrugated appearance, described by Brongniart, 

 p. 127, pi. 17. The stem to which the other is attached is 

 identical with C. cruciatus, Sternb., pi. 49, f. 5, thus shewing 

 this supposed Calamite stem to be really a rhizome or creeping 

 rootstock. 

 Loc— Shale above the Bensham Seam, Jarrow. (H. C. 21). 



40. Two branches springing from the point of a broken stem. 



It seems to shew that when the main stem was damaged the 



two branches took a leading upright position. 



Loc. — Shale above the Bensham Seam, Jarrow. (H. C. 71). 



41, — Catamites L. et H. Type specimen, F. F., pi. 78. 



Root portion of three small stems, with branching roots at- 

 tached to the lower joints of f. A, and unbranched rootlets 

 springing from the apertures that surround the joints of figs. 

 B, C. 

 Loc— Newcastle Coal-field. (H. C. 28). 



Branches and Foliage. — Rami et ramulifoliosi. 

 42. — Asterophyttites sp., Lebour, 111. Foss. Pits., pi. 4. Type. 



Branch and branchlets. Branch with eight prominent joints, 

 the internodes slightly grooved and rising into ridges or knobs 

 at the joint; slight appearance of a whorl of small leaves 

 round the joints ; branchlets springing from third, fifth, and 

 seventh joint on the left side. There are small branches with 

 fine branchlets at several of the joints. Branchlets with 

 whorls of fine leaves. Resembles L. et H., figure pi. 173.
