214 OTTOKAKIA. 



Vegetative shoots woody, bearing spirally disposed leaves. 

 Leaves wedge -shaped, reaching a length of 13 cm., usually 

 divided by a deep median sinus into two narrow wedge- shaped 

 lobes, truncate distally and tapering gradually to the proximal 

 end of the lamina. Leaves sessile, attached to the axis by a 

 narrow base. The lamina is traversed by numerous spreading 

 and occasionally forked veins, following a course parallel with the 

 edge of the leaf. Organs of reproduction unknown. 1 



Mr. Seward has pointed out that the South African leaves hear 

 a close resemblance to those of the British Lower Coal Measure 

 species Psygmophijllum flabellatum (L. & H.), aud also to the 

 individual leaflets of the compound leaf, Rhipidopsis ginkgoides, 

 from India. 



Psygmophyllum Kidstoni is known only from the Pernio - 

 Carboniferous locks of the Transvaal. 



Not represented in the British Museum collection. 



2. Psygmophyllum (?), sp. (from Kashmir). 



Mr. Seward 2 has recently figured an imperfect impression from 

 Kashmir, which he doubtfully assigns to this genus. It differs 

 from the other members recorded in the lamina of the leaf being 

 shorter and relatively broader. The leaf is divided into two 

 symmetrical halves by a shallow groove, which may be due to 

 lobing, or possibly to some extent to tearing. The petiole is 

 absent. The veins are numerous, radially disposed, simple, or 

 occasionally dichotomised. Mr. Seward also compares this specimen 

 with Ginkgo, Actinoptens, and Rhipidopsis. 



Genus OTTOKARIA, Zeiller, 1902. 



[Pal. Iudica, n.s., vol. ii, prelim, note.] 



The characters of this genus are those of the only known species, 

 Ottolcaria bengalensis. Zeiller 3 described this leaf under the name 

 Feist in antelia, but he transferred it subsequently 3 to a new genus 

 Ottolcaria, as the former designation had been already used by 

 Mr. Lester Ward for another fossil.
