work of the world. The circulating museum, if properly used, may 

 become an unspeakable boon in educating and edifying the children ; 

 in drawing-out their observational faculties and building-up their 

 reasoning powers. If the Essex Field Club's Museum will aid in 

 such a work, every educational realist will admit that it will not be 

 simply benefiting the children and teachers in this or that village — it 

 will be indirectly elevating the entire county. 



EPPING FOREST RUBI. 



By J. T. POWELL. 



PART II.— ADDITIONS AND CORRECTIONS. 



HP WO more seasons among the Forest brambles have resulted in 

 several additions to the list given in the Essex Naturalist 

 for 1889 (Vol. iii., p. 20), as well as some revision of that list. 



I have again been greatly indebted to Prof. Babington for his aid 

 in determining difficult forms, and more particularly this year have I 

 been helped by the Rev. W. Moyle Rogers, F.L.S., one of our best 

 batologists, who has not only named the specimens sent to him 

 through the Watson Botanical Exchange Club, but has in the kindest 

 manner rendered me invaluable personal assistance. 



Mr. Rogers refers to R. rho7}ibifolius, Wei he, a bramble which 

 occurs abundantly about Walthamstow and Snaresbrook, and which 

 I formerly placed under R. rhamtiifolius. We have also plenty of 

 the robust rhamnifolius of the English authorities. A form near 

 villicaulis Mr. Rogers identifies as R. pyramidalis, Kalt. This occurs 

 sparingly at and near High Beach. The bramble previously recorded 

 as R. sertijiorus, P. J. Miill, is believed by the same authority to be 

 a hybrid, probably rusticanus x pyra/nidaiis, in which case the name 

 sertiflortis must be cancelled. A very distinct form of macrophyllns 

 has been named by Prof. Babington, R. amplificatus^ Lees. This 

 occurs at Leppitt's Hill, Buckhurst Hill, and near High Beach. 

 The professor has also given the name R. plinthostylus, Genev., to a 

 bramble from Hawk Wood, Chingford, which I had included under 

 Koehleri. R. spretigelii, Weihe, recorded in 1886 by Mr. J. G. 

 Baker, I have found to be one of the most widely-spread of the 

 Forest Rubi.
