60 D. G. Lillie—Fossil Flora, Bristol Coal-field. 
interesting plant petrifactions have also been obtained, and we may 
commence with a brief notice of these. 
PETRIFACTIONS. 
In addition to impressions found in the shale bordering on the coal- 
scams, a limited amount of petrified material has also been obtained, 
which is of special interest, because our supply of structure material 
has hitherto been confined to one or two seams in the Lower Coal- 
measures of Yorkshire and Lancashire. This material was originally 
recognized by Mr. Bolton, F.G.S., Curator of the Bristol Museum, 
who drew my attention to it. It has only been obtained at one 
locality, Staple Hill, about 3 miles to the north-east of Bristol, on 
the north side of the Kingswood anticline. A sinking was made here 
a year or two ago, through the Pennant Grit, but was afterwards 
abandoned at a point rather beyond the base of the Pennant. At this 
level a peculiar breccia-conglomerate, containing numerous angular 
and rounded pebbles, set in a sandstone matrix, was met with in 
sinking the shaft. This rock will be more fully described by. 
Mr. Bolton. It is only necessary here to add that, in addition to the 
pebbles, this breccia contains numerous fragments of stems and petioles 
of plants in some of which the structure is preserved; the material 
being calcified. The amount of this conglomerate is very limited, 
and it is very doubtful whether any more can be obtained in the 
future. Many of the blocks thrown out from the shaft have become 
considerably weathered, and the plant petrifactions quite spoilt for 
purposes of section cutting. However, a number of sections have been 
cut of the petrified material, and several of these proved to be well- 
preserved stems or petioles. Twigs of Cordaites appear to be the 
commonest fossils, while in, addition a well-preserved petiole of 
Myeloxylon has been obtained. It is hoped that an opportunity will 
be found to describe these structure specimens before very long. At 
present we must content ourselves with a record of their discovery. 
IMPRESSIONS. 
We now pass to a record of the plant impressions obtained from the ° 
Farrington Series in the Bristol district. 
The following list of plants, recorded by Dr. Kidston in 1887, 
comprised the entire flora then known from the Farrington Series of 
this area, and no further additions have been made, as far as I am 
aware, up to the time of writing :—
