Extract

On the Fossil Plants collected during the Sinking of the Shaft of the Hamstead Colliery, Great Barr, near Birmingham.

The area comprised in the county of Stafford embraces five coal fields—

I. The Goldsitch Moss Coal Field, in the extreme north-east of the county.

II. The Cheadle and Churnet Valley Coal Field.

III. The Wetley and Shafferlong Coal Field.

IV. The Coal Field of the Potteries.

V. The South Staffordshire Coal Field.

The three first mentioned are of small extent, and as I know little of their fossil flora they are omitted from this series of papers on the Carboniferous Flora of the Staffordshire Coal Fields.

I, however, devote a separate communication to the fossil plants met with while sinking the shaft of the Hamstead Colliery, Great Barr, as a considerable part of the rocks passed through during this operation is clearly Upper Coal Measures, not Permian, as has been generally stated. The palæontological evidence, therefore, becomes of special importance in determining the age of the red shales occurring in the upper part of this sinking, which have been usually mapped as Permian.

page 328 note † The lateral cicatricules in the leaf scars of Lepidodendron, Lepidophloios, and Bothrodendron, probably performed the same function. When the structure of these lateral cicatricules is examined, they never show any trace of vascular tissue, but are filled with lax parenchyma. A good figure of their structure is given by DrFelix, (Untersuchungen iiber den Bau weslfälischer carbon Pflanzen, pl. ii. fig. 3f, König Preusseschen geol. Landesanslalt, 1886 Google Scholar.

page 334 note * I exclude Stigmaria, which is the root of several Lycopods, and as none of the Lower Carboniferous Lycopods pass into or above the Millstone Grit as far as I know, Stigmaria, being the root of any one of these Lycopods (Lepidodendron, Sigillaria, Lepidophloios) cannot be regarded as a true, individual species, and though these Lower Carboniferous Stigmaria are individually undistinguishable from the Stigmaria of the Upper Carboniferous, they cannot be regarded as specifically the same.
