184 THE LATE DR. NEWELL ARBER : CRITICAL STUDIES 
pedicel very narrowly and elongately wedge-shaped, 8 mm. long. Apex 
bluntly acute. 
Remarks.—This rare type in Dr. Moysey’s collection is figured on PI. 9. 
fig. 26, natural size, and nearly twice enlarged in fig. 27. In the shape of 
the lamina it appears to me to differ from any other sporophyll known to me, 
though it may approach to Lesquereux’s L. ovatifolius (‘Coal Flora,’ vol. ii. 
p. 438, pl. 69. fig. 32). 
Type. No. 4018. Carbon. Plant Coll., Sedgwick Museum, Cambridge.

JDiagnosis.— Dimensions and shape of cone unknown. Sporophylls small 
or of medium size, broadly elliptical, length 1:5-2 cm., usually about 2 cm., 
greatest breadth 7-10 mm., usually about 8 em. Pedicel similar in shape 
to the lamina, but usually distinctly shorter. 
Remarks.—This cone is distinetly rare in Britain. No specimen of the 
complete cone, seen in surface-view, is known. A very few examples of 
what is practically a transverse section of the cone have been found, with 
the sporophylls all spread out in one plane, and also of detached sporophylls. 
This cone has hitherto been known as Lepidostrobus anthemis, Konig. 
König’s memoir, entitled * Icones Fossilium Sectiles,” 
published, though copies were widely distributod about the year 1851 on 
the death of the author. The lack of formal publication appears to me to 
render invalid the new generic and specific names contained in this memoir, 
and it is therefore necessary to fall back on Schimper’s Lepidostrobus 
was, however, never 
radians, expressly proposed for the specimen originally figured without 
specifie determination by Brongniart. 
No. 67. On PI. 9. fig. 28 several sporophylls are seen, natural size, still 
attached to an axis. 
* Indicates figures of typical examples.
