In the Journal ofEcolo(/i/ (x. no. 1), Mr. II. H. Yapp suggests the 

 formation by tlie Ecological Society of "a central 'Ecological 

 Reference Herbarium,' or a scries of such herbaria, housed in suitable 

 centres." This " would aim not so much at recording the occurrence 

 of species as at accunmlating material which might in time be a 

 veritable mine of information useful to ecologists : such as, for 

 example: developmental stage; growth forms (including root- 

 systems) ; forms of leaves in diiferent parts of the same plant or at 

 different seasons of the year, and seasonal status generally ; habitat 

 forms and so on. The winter conditions of herbaceous plants, a sub- 

 ject ignored by our Eloi-as but nevertheless of great importance in 

 connexion with the study of partial habitats, would no doubt form an 

 important part of any ecological herbarium." The scheme thus 

 adumbrated is to be discussed later. Mr. Yapp, in addition to the 

 essay in " The Concept of Habitat," in which the above suggestion 

 occurs, contributes to the same number a paper on " The Dovey 

 Salt Marshes in 1921." The number also contains "The Ecology of 

 the Gorse with special reference to the Growth-forms on Hindhead 

 Common," by £. G. Skipper (with plate); "Changes in the Coast 

 Vegetation near Eerrow, Somerset," by H. Stuart Thompson ; " The 

 Distribution and Origin of Salix in South Africa," by J, Burtt 

 Davey ; "The Vegetation of West Greenland," by K. E. Holttum ; 

 "A Spitzbergen Salt Marsh," by John Walton (with 3 plates). 



The Kew Bulletin (No. 5) contains a continuation of Miss 

 Wakefield's " Fungi Exotici " and of " Contributions to the Flora of 

 Siam " by W. F. Craib, in wdiich many new species are described. 

 Mr. W. 13. Turrill describes and figures flowers of a new variety of 

 Erica vaganSy named hevernensis from the place of its discovery— 

 St. Keverne, Cornwall. The new plant differs from the usual form of 

 the species in the shape and colour of its corollas, which "are broadly 

 campanulate, with a wide open mouth and well developed, more or less 

 reriexed lobes. In colour the fresh corollas are a charming rose-pink 

 with no tinge of purple." Only one plant was observed, but from 

 this the discoverer, Mr. P. D. Williams, of Lanarth (who also 

 discovered the hybrid between M. vagans and JE. tetralix, named 

 after him), took cuttings which grew and produced seed ; the form 

 now occupies a whole bed at Kew. " It is imjwssible at present to 

 decide fully the botanical status of this plant : no morphological 

 characters which would suggest a hybrid origin have been found." 



The Government of Chosen, Seoul, Corea, has published in a 

 handsome volume Ail Enumeration of Flants hitherto knoioii in 

 Corea, by T. Mori, " Instructor in the Seoul First Higher Common 

 School." In his preface the author summarises the work that has 

 been done on the flora, and continues : " Although the plant life 

 Corea is more and more carefully studied and investigated, yet 

 complete list of the plants has been published, to the great inc 

 venitjnce of students as well as collectors. That is the reason why I 

 have boldly compiled this Work in spite of my poor knowledge.
