In a paper entitled Beitrdge zur Kenntnis der Pteridophyten- 

 gattung PhyUitis (reprinted from Q^sterreich. Botan. Zeitschrift. 

 1914, pp. 19-36, 5 pis. and 2 maps), Friedrich Morton publishes 

 two studies of the genus PhyUitis Ludw. [Scolopcndrinm Adans.) : 

 (i.) the finding of P. Heviionitis (Lag.) 0. Kuntze in the 

 Quarnero region, and the distribution of the species ; (ii.) the 

 systematic position, distribution, and ecology of P. hybrida 

 (Milde) Christensen. Having made a comparative study of this 

 species and its allies in respect of the following structures : (1) the 

 endings of the vascular bundles in the frond-lobes ; (2) the posi- 

 tion of the sori ; (3) the indusium ; (4) the layers of tissue from 

 which the indusium arises, he is of opinion that P. hybrida is no 

 hybrid, but an independent species, occupying a systematic posi- 

 tion between Ceterach and P. Scolopendrimn, similar to that of 

 P. Hemionitis, to which, in its anatomy and morphology, it is 

 most nearly akin. It is endemic in the southern Quarnero 

 Archipelago, in the Adriatic Sea. 



We regret to note the death, at the age of seventy-five, of 

 M. Philippe van Tieghem, Professor of Botany at the Paris Natural 

 History Museum. Van Tieghem's most important botanical work 

 was on the comparative anatomy of the vegetative structure of 

 the flower in numerous families of seed-plants. Many of these 

 communications were published in the Annales des Sciences 

 Naturelles, of which he was botanical editor from 1882, when he 

 succeeded Decaisne, until the time of his death. One of the best 

 known and most important appeared in 1869 on the comparative 

 anatomy of the female flower and fruit in Gymnosperms, in which 

 he attacked the problem of the morphology of the cone-scales 

 from an anatomical point of view, and demonstrated a uniform 

 plan of structure in this organ throughout the Pinacete. In 1884 he 

 produced his Traiti de Botanique, the second edition of which (1891) 

 contained 1855 pages. His systems of classification were, as far as 

 concerned the flowering plants, based primarily on characters of the 

 ovule ; they were conceived on too narrow lines, besides being bur- 

 dened with a novel and extensive terminology. Van Tieghem also 

 made valuable contributions to the study of the phycomycetous fungi , 

 especially on the morphology and physiology of the Mucorineas. 



The Journal of the Royal Horticultural Society (xxxix. part 3, 

 April) contains an interesting illustrated paper by Mr. E. A. 

 Bunyard on " The History and Development of the Strawberry," 

 and a lecture by the Eev. G. Henslow on " The Evolution of 

 Plants and the Directivity of Life, as shown by the Eeproductive 

 Organs " ; as well as contributions from the Wisley Laboratory 

 and many papers dealing with horticultural matters. 



The degree of D.Sc. in Botany has been conferred by the 

 University of London on Mr. H. F. Wernham, of the Department 

 of Botany, British Museum.
