92 Dr Arber and Mr Goode, On some fossil 
of which may have been derived from Devonian, while others 
were certainly obtained from the Carboniferous rocks, must be 
discarded, as there were no records as to the localities from which 
any of the specimens were collected. The circumstances relating 
to these records have already been explained by one of us* else- 
where. . 
To sum up the results of previous work on the Devonian 
plants of North Devon, we may conclude that the only valid and 
satisfactory determinations so far all relate to specimens from the | 
Baggy beds, and that they consist of Sphenopteris sp., the Knorria 
casts of some Lycopodiaceous genus, and very doubtfully Astero- 
calanutes scrobiculatus (Schl.). The best examples of these will 
be described here, with an account of some specimens from a new 
locality at Baggy Point, which was originally discovered by 
Dr Young in 1907. We may commence with the first plant 
record from the Lynton beds, from material collected by 
Mr G. F. Tregelles, of Barnstaple, in 1911. 
DESCRIPTION OF THE SPECIMENS. 
An obscure Plant impression from the Lynton Beds. 
Text-fig. 1. 
Text-fig. 1 represents one of the plant remains} obtained by 
Mr Tregelles from a quarry to the west of Lynton at the head of 
the Valley of the Rocks, in a lane behind “Rock Lodge.” The 
mineral representing the plant somewhat recalls graphite in ap- 
pearance. It consists of a short axis bearing several lateral 
organs, which, despite the absence of any nervation, are more leaf- 
hike than branch-hke in form. The axis is fairly stout, incomplete, 
especially above, and measures at least 3°8 cm. in length and 
4°5 mm. in width at the base. The lateral organs appear to be 
arranged in a close spiral, there being eight or more, all in con- 
tinuity. The bases of several others are also seen broken off 
abruptly. None however are complete. They measure from 7 to 
10 cm. in length. They are lanceolate in form, and the apex ap- 
pears to be elongately acute. They are 7—8 mm. across at their 
broadest part. They show no trace of nerves, and there is no real — 
evidence of any dichotomy. The division of one of the lateral 
members, which is seen on the left-hand side of the specimen 
(text-fig. 1), is in all probability due to bad preservation, and not 
a natural feature.

+ We understand that another similar specimen has been presented by 
Mr Tregelles to the Atheneum Museum, Barnstaple. The figured specimen was 
given by him to the Sedgwick Museum, Cambridge.
