LEPIDOPHLOIOS, AND ON THE BEITISH SPECIES OF THE GENUS. 561 



Eenault figures some specimens which he refers to Lepidophloios macrolepidotus in 

 Flore foss. le terr. houil. d. Comentry, deux, part, p. 507, pi. lviii. fig. 1 ; pi. lx. fig. 

 3, 4 ; but his fossils do not appear to me to be Goldenberg's species — their leaf-cushions 

 are much more prominently keeled, and his specimens have, in fact, more of the character 

 of Lepidophloios acerosus, L. and H., sp., though possibly they may not be referable to 

 this species. 



Lesquereux also figures a specimen which he refers to Lepidophloios macrolepidotus* 

 but I am also doubtful about the identification of this specimen. 



The specific value of Goldenberg's Lepidophloios macrolepidotus has yet to be 

 determined. It seems quite possible that it may be only an aged example of 

 Lepidophloios acerosus, L. and H., sp.

Specific Characters. — Leaf-cushions on young branches directed upwards, on the 

 older stems directed downwards, rounded, not keeled, exposed portion on older stems 

 with straight or slightly convex sides, basal portion pointed, distal margin rounded. 

 Leaf-scar placed at the apex of the cushion, transversely elongated, oval on young stems, 

 lateral angles pointed or acute on older branches. Cicatricules three, punctiform, and 

 placed a little below the centre of the scar. On young stems the leaf-cushion is much 

 elongated, rounded and truncate, terminating in a transversely oval leaf-scar, cicatricules 

 seldom preserved. Fruit a stalked elongate oval cone with leaf-cushions directed 

 upwards, and borne on Halonial branches with downward directed leaf-cushions. At the 

 point of attachment of the cone-stalks with the parent branch, the leaf cushions are 

 bent back on all sides, and thus form a rosette, in the centre of which is a small circular 

 vascular scar. 



Remarks. — Fig. 2, PI. I. shows portion of a branch removed from its matrix, and 

 illustrates the form of the leaf-cushion on the fully-developed plant. PL II. fig. 6 gives 

 a reduced figure of the Halonial condition, and shows the rosettes formed by the back- 

 ward turned scales, in the centre of which are the little points of attachment of the cone- 

 stalks. Another specimen showing these characters more clearly is reproduced, natural
