two Labiates, a second species of Alder, Picea excelsa, and Najas 

 minor. Thus the southern element in the Cromer flora is now more 

 marked than was formcrly realised, and in all probability it includes 

 several extinct species. These pre-Glacial plants suggest climatic 

 conditions almost identical with those now existing, though slightly 

 warmer, a difference probabl}^ largely due to the fact that Britain 

 was then united with the Continent. Arber (Cambridge).

 from Vereeniging (Transvaal). (Quart. Journ. Geol. Soc. LXIV.

The authors begin by a discussion of the general section at 

 Vereeniging, and previous opinion as to the position of the beds in 

 the Karroo System. They conclude that the fossils favour the inclu- 

 sion of the strata in the Ecca Series (Lower Karroo) rather than in 

 the Beaufort series (Middle Karroo). The flora is compared with the 

 plants known from other districts in South Africa, especially with 

 those from the Tete basin on the Zambesi. It is shown that Lepi- 

 dodendron, in addition to other Northern t3'^pes previously recorded 

 from South Africa, adds another link connecting the Northern 

 and Southern types of Carboniferous and Permian floras, and that 

 the distinction between these two floras has been exaggerated. 



A list is given of the 15 species, now known from Vereeniging, 

 four of which are here recorded for the first time. The authors 

 next describe the specimens, beginning with a new variety of 

 Glossopteris, G. angustifolia Brongn. var. taenioptevoides, in which 

 anastomoses between the lateral nerves are very few and quite 

 rare. This leaf is compared with Megalopteris and other fronds. 

 Several other species of Glossopteris, including one comparable with 

 G. retifera Feistm. are discussed. Ganganiopteris cyclopteroides and 

 SigiUaria Brardi are also mentioned. Callipteridiimi is recorded 

 from South Africa for the first time, and a new species of Z,f^/<io 

 dendron, L. Vereenigingense is described and figured, the leaf cush- 

 ions of which appear to be of the type of L. acideatian , but are 

 not specifically identical with that species. L. Pedroamim (Carr.) is 

 also recorded for the first time. Cordaites Hislopi is discussed and 

 reasons are given for removing this species from the genus Noeg- 

 gerathiopsis. A small Araucarian cone-like fossil is figured under 

 the name Conites sp. 



In the conclusion, each record is considered individually with 

 regard to the age of the beds, and a füll bibliography is appended.

that the "melasmatic tissue" of Hick, forming the bündle sheath, 



functioned as the path for conduction of the products of assimilation, 



but he does not support this assertion by conclusive facts.
