MONG the numerous plant remains preserved for us as impressions 
on the Palaeozoic rocks are some digitate clusters attached to 
branching petioles devoid of lamina, and associated with, and sometimes 
attached to, leaves of the Sphenopteris type. 
They were first investigated and named by Dr. Stur 1 . The species 
Calymmatotheca Stangeri , Stur, may be taken as the type of these impres- 
sions. Dr. Stur regarded the constituent parts of the cluster as indusial 
valves, but they were differently interpreted by Renault, who figured them 
in his ‘ Cours Fossile’ 2 as sporangia. 
M. Zeiller 3 also supported the sporangial interpretation of the lobes. 
Several species of genuine sporangia have subsequently been included in the 
genus Calymmatotheca , e. g. C. affinis and C. asteroides . They were all 
founded on casts, however, and it was not until May, 1902, that petrifactions 
were obtained. Sections of coal nodules from the Gannister beds of Dules- 
gate and Hough Hill have recently been yielding a good many of these 
synangia, some of which have been beautifully cut in series by Mr. Lomax 
of Bolton. 
This led to a re-investigation 4 of Stur’s type-specimens, which has con- 
vinced me that he was right in his interpretation of his specimens, and that

4 Dr. Scott and Prof. Oliver tell me they have come to the same conclusion after a careful 
inspection of the specimens. The re- investigation was rendered possible by the kindness of the 
Director of the Geol. Reichsanstalt at Vienna, who, at the request of Dr. A. Smith Woodward, F.R.S., 
lent the valuable specimens in question to the Geological Department of the British Museum, so as to 
give English Palaeobotanists an opportunity of examining them.
