Fungus attacking* seedling* Conifers. By Geo. Massee (Gard. 

 Chroji. No. 882, p. 347, figs. 144, 145 ; Nov. 21, 1903).— Larch seedlings 

 are liable to be attacked by a fungus known as Melampsora laricis, which 

 in one stage of its existence is parasitic on the leaves of the common 

 Birch, in the form of a yellow rust. In many cases the young Larches are 

 severely injured or killed outright by this fungus. Another species be- 

 longing to the same genus, M. pinitorqua, commonly known as the 

 " Pine-branch twist," is very injurious to the shoots of seedling Pines, 

 causing them to twist and become contorted. The other stage of this 

 fungus is very common on the leaves of Poplars. " Moral : do not form a 

 nursery of Conifers in a locality where Birches or Poplars abound." —

Gentiana lutea (Gard. p. 59; 25/7/03). — The leaves are broadly 

 ovate, large, forming a rather dense tuft some 12 to 18 inches high. The 

 flowering stems, which are from 3 to 4 feet high, have numerous large 

 leaf-bracts oppositely arranged. In the axils of these the yellow flowers 

 are freely produced in bunches in June and July. The growths usually 

 flower when two years old. — E. T. C. 



Geranium argenteum. By S. Arnott (Journ. Hort. June 18, 1903, 

 p. 640). — This very choice rockery Geranium, from the Swiss and Italian 

 Alps and the Pyrenees, is described, and rules given for its successful 

 cultivation. — C. W. D. 



Geranium grandiflorum. By Rev. C. Wolley Dod, V.M.H. (Gard. 

 p. 184 ; 12/9/03). — A good specimen of this Geranium is illustrated. It 

 is a Himalayan plant, of great merit as a garden ornament. The flowers 

 are much larger and more blue than those of G. palustre, and the growth 

 is dwarfer and of better habit than G. pratense, of which species some have 

 thought it to be a local variety. It grows on level borders in any rich, 

 well-drained soil, «but gardeners must find out for themselves the best 

 position for it in their own gardens. — E. T. C. 



Gloriosa Leopoldi. By Ed. Andre (Rev. Hort. Dec. 1, '1903, 

 pp. 548-9 ; coloured plate). — A splendid, clear yellow form, with flowers 

 7 or 8 inches across, produced freely. Culture same as with other 

 species of same genus, i.e. warm house, water freely when flowering, then 

 dry off and store tubers until February in fine dry sand. — C. T. D. 



Gloriosa Rothschildiana. By J. O'Brien (Gard. Chron. No. 856, 

 p. 322, fig. 125 ; May 23, 1903). — A description and figure are given of a 

 remarkably fine new species of Gloriosa which was collected by Major 

 H. B. Rattray in Uganda, and which has been flowered by the Hon. W. 

 Rothschild at Tring Park. " Its pure glowing crimson-coloured flowers 

 constitute it one of the showiest of warm-house plants." Short descrip- 

 tions of other species of this genus are given, showing how they differ 

 from one another and from the subject of the present article. A brief 

 note as to the cultivation of these plants is also given. — G. S. S.
