elongated stalk, arising from an irregular black tuber-like sclerotium. 

 The mycelium preceding the sclerotium stage is said to be parasitic on the 

 Wood Anemone. 



Virescent Primroses. — Mr. Holmes also showed flowers with slightly 

 abnormal calyx, but with a virescent corolla. There were no stamens, 

 but the pistil was malformed, being open and terminating above with 

 styliform processes. In one, a portion of the placenta was parietal, 

 the free portion carried a minute tuft of a foliar nature at the 

 summit. 



Hclxine Soleirolii. — Mr. Odell brought a specimen of this plant of the 

 family Urticaceae. It is a native of Corsica, having very small leaves, and 

 minute male and female flowers, somewhat resembling those of a Stinging 

 Nettle. It is monoecious. 



Schinus Molle Diseased. — Dr. Bonavia sent some leaves of this tree 

 apparently diseased. Dr. M. C. Cooke undertook to examine them. 



Carnation Leaves Injured. — Dr. William G. Smith reports on the 

 specimen sent to him as follows: — "On March 13 you sent some 

 Carnation leaves with diseased tips. After examination I find no sign of 

 fungi. It appears to me that the disease is due either lo water remaining 

 on the tips after overhead watering, or to exudation of water at the tips. 

 As only the ends of a few leaves were sent, no examination of the rest of 

 the plant could be made. Useful suggestions on Carnation diseases 

 — including, I think, this one — will be found in Vol. xxv., p. 33, also a 

 report of my own in Vol. xxxiii., p. 29. A paper by Woods (U.S.A. Dept. 

 Agric), which deals with a bacterial disease, would also furnish useful 

 hints on treatment." 



Oleander Diseased. — Dr. W. J. Russell sent some leaves growing on 

 " fine and hitherto very healthy pink-flowered plants in a conservatory ; 

 but while the rest of the plant looks healthy, several of the branches are 

 fading, the attack coming from a point close to the main stem." They 

 were forwarded to Dr. W^illiam G. Smith for further examination. 



Mistleto at Oxford. — Mr. W. G. Baker writes as follows with regard to 

 this subject : — " With reference to the Mistleto in the Botanic Gardens, I 

 cannot find it recorded when it was first introduced. The following list 

 contains all the trees upon which it grows here : — Vigorous : CratcBgiis 

 Oxyacantha, G. 0. var. rosea, Ostrya vulgaris, ^scultis (Pavia) ftava, 

 Cladrastis tinctoria, Tilia vulgaris, Apple tree. Moderate : Cratcegus 

 odoratissima, Acer monspessulanum, Juglans nigra. Weakly : JEsculus 

 Hippocastanum, Pyrus Aria, Salix alba, Fraxinus Ornus. I have 

 observed seeds germinate on the following trees, but have never got 

 beyond that stage : — Fraxinus puhescens, Diospyros virginiana, Pyrus 

 intermedia, Cerasus serotina, Gymnocladus canadensis, Ailantus glan- 

 dulosa, Corylus Colurna.'' Mr. Burbidge, who forwarded Mr. Baker's 

 communication from Oxford, adds : — " I have never seen it growing on 

 the Beech or Viburnum, as stated at the Committee on March 12." 



Hepatica triloba alba. — Herr A. M. C. van der Elst, of the Royal 

 Tottenham Nurseries, Dedemsvaart by Zwolle, Holland, sent flowers of 

 this rare variety. (" They have suffered a little from the bad weather, but 

 when fully developed they are quite as large as the double red and larger 

 than the double blue. The original plant was found some years ago in
