Stigmaria sp. 



Stigmaria ficoides, L. et H., Foss. Flora, pi. 35. 



,, ,, Williamson, Mem. Stigni., pi. 13, f. 64-66. 



237. — Stigmaria ficoides, L. et H. Type specimen, F. F., pi. 35. 



The Hutton label on this specimen is, " B., to be returned," 

 on both parts of the root, which has been cut through longi- 

 tudinally and one part figured pi. 35. Only a part of the cast 

 of the pith remains, as shewn in the plate. Other portions of 

 evidently the same root from the same locality are in the 

 Collection of the Natural History Society, and shew the central 

 pith attached or with medullary rays radiating outwards. 

 (The statement on page 105 of the Fossil Flora, that the speci- 

 men figured on pi. 35 is from Weardale, is an error. The 

 specimen figured on pi. 35 is a section of a stem in iron- 

 stone, from Dysart, in Scotland. The specimen figured on 

 pi. 36 is from near Stanhope in Weardale, and is so labelled. 

 It is in the Collection of the Natural History Society with its 

 original label on it. Being in two pieces it was not recognised 

 till about a year ago. It is in a fine grained sandstone of the 

 Carboniferous-limestone series, and probably is the root of 

 another species of Lepidodendrori). 



Loc. — In clay-ironstone, Dysart, Fifeshire, Scotland. (H. C. 

 507). 



238. Counterpart of above specimen, which has been cut 



through longitudinally to shew the cast of the pith and the 

 cylinder in which it was situated. 



Loc. — In clay-ironstone, Dysart, Fifeshire, Scotland. (H.C. 

 508). 



Remarhs. — This specimen from the Carboniferous rocks of 

 Dysart, Fife, appears to differ somewhat from the above" Coal- 

 measure form. The tubercles of the rootlets are, from the im- 

 perfect state of preservation, not visible. On another specimen 

 from the same locality the tubercles are finely preserved, and 

 shew the manner in which the rootlets have been attached to 

 the main root. The pith-cavity and the casts of the vessels 

 radiating from it through the woody cylinder are well preserved 

 in this clay-ironstone example. 



As mentioned above, the Lindley-Hutton Type-specimen F.F., 

 Plate 36, is in the Collection of the Natural History Society,
