of Liassic age in the State of Oaxaca in southern Mexico. The 

 geologic section is discussed and tables showing the determined 

 species and their affinities are given. Species are listed as follows: 

 Anomosamites 1, Otosamites 17, Pterophyllum 2, Pterosatnites 1, 

 Ptüophylluni 3 , Stangerües 1 , Williarnsonia 6 , Zamites 2 , Cycado- 

 spermum 1 , Cycadolepis 1 , Araucarioxylon 1 , Phoenicopsis 1 , Noeg- 

 gevathiopsis 1 , Yuccites 1 , Trigonocnrpus 1 , Rhabdocarpits 1 , Ale- 

 thopteris l , Ciadop hlebis 1 , Coniopteris 1 , Dicksonia 1 . Glossopteris 

 2, Laccopteris (?) 1, Sphejtopteris 1, Sagenopteris 1, Taeniopteris 3, 

 and Equisetites 1. This flora is remarkable in consisting of 70 per- 

 cent of cycadophytes and in containing such old types as Glossopteris 

 and Noeggerathiopsis. Berry.

Describes a fossil leaf of unknown affinitj^ from the Tertiary, 

 stated to be probably Miocene. A non-commital generic name, 

 LebephyUtan is proposed and the species is named Reineckei after 

 the collector. A reference to the family Urticaceae is suggested.

The species was studied on Scilla bifolia, which is its only host 

 in Britain. Infection takes place only in the seedling stage, and 

 the mycelium is confined to the stem, hibernating in the flattened 

 „cushion" and growing up with the flowering stem each year. The 

 mycelium is uninucleate. Spores are produced in the anthers and 

 occasionally in the ovary. Their formation is accompanied b}'- a 

 nuclear fusion, the binucleate condition being stated to arise b}^ the 

 deliquescence of alternate transverse septa. The spores retain their 

 vitality for 3 months. Germination is varied, the spores giving rise 

 to a Short promycelium bearing a hemibasidium, or to a slender 

 germ tube with a chain of oidia. The time elapsing before germi- 

 nation also varies. 



No conjugation of the spores produced from the hemibasidium 

 was observed. E. M. Wakefield (Kew).
