288 SCIENCE PROGRESS 



few isolated papers, chiefly by Dr. E. W. Berry, who publishes 

 "The Origin and Distribution of the Family Myrtaceae " (Bot. 

 gas. vol. lix.) ; " A Species of Copaifera from the Texas Eocene " 

 (Torreya, vol. xv.) ; and " An Eocene Ancestor of the Zapo- 

 dilla " (Amer. Journ. Sci. vol. xxxix.). K. Nagel deals with 

 the Juglandaceae in Junk's Fossilium Catalogns, II. Plantce ; 

 while Prof. Kryshtofovich has a memoir on " The Butternut 

 (Juglans cinerea L.) from fresh-water deposits of the province 

 of Yakoutsk " {Mem. Comite Geol. livr. 124, Petrograd). 

 Sinnott and Bailey discuss in a very general way the early 

 history of the Angiosperms {Amer. Journ. Bot.). M. C. Stopes 

 in the Lower Greensand Flora {ante) describes the anatomy of 

 very early members of the group. 



The Higher Gymnosperms are dealt with in a number of 

 papers elsewhere mentioned, particularly in those touching on 

 wood anatomy. R. Holden describes the details of a Jurassic 

 wood from Scotland {N. Phytologist, vol. xiv.). L. L. Burlin- 

 game in " The Origin and Relationships of the Araucarians " 

 {Bot. Gaz. vol. lx.) goes carefully into the palseobotanical evi- 

 dence for the various theories on the phylogeny of the group, 

 which affords a useful general summary of recent work. 



The Bennettite^e are dealt with by F. Pelourde {Prog. 

 Rei bot. 5), in his general article " Les progres realises dans 

 l'etude des Cycadophytes de l'epoque secondaire." H. H. 

 Thomas describes a specimen of the male flower of William- 

 sonia from the Paris museum {Proc. Cambridge Phil. Soc, vol. 

 xviii.) ; Dr. D. H. Scott popularly re-describes the famous Isle 

 of Wight Bennettites {Proc. Hampshire Field Club) ; and F. 

 Krasser records male flowers of Williamsonia from the L. Lias 

 of Steierdorf {Anz. K. Akad. Wiss. Wien, vol. lii.). But the 

 important contribution to this group is the work of H. H. 

 Thomas, who describes a new genus of fructifications, " On 

 Williamsoniella, a new type of Bennettitalean flower " {Phil. 

 Trans. Roy. Soc. London, ser. B, vol. ccvii.). From the asso- 

 ciated foliage and stems, together with the fructifications, he 

 deduces the whole appearance of the plant, of which he gives 

 a restoration showing its suggested habit. The outstanding 

 features of the fructifications are their extremely small size 

 and relatively simple organisation. This description affords 

 the basis for a general comparison of members of the group.
