Injuries to Leaves of Bhododendron and GauUheria. — Dr. 

 Hugo Miiller exhibited leaves of R. ponticuin and Gaultheria 

 Shallon with the edges completely eaten out, some being 

 destroyed as far as the midrib. The plants from which the 

 leaves were taken were injured regularly every spring. Mr. 

 McLachlan suggested that the injury was caused by weevils 

 (probably a species of Otiorhynchus). The better way to deal 

 with them would be to watch at night, and shake the insects 

 over a sheet of white paper or calico, and destroy them at regular 

 intervals. 



Iris iberica. — Mr. G. F. Wilson brought plants showing con- 

 siderable range of variations in seedlings of Iris iberica. One 

 was a singularly large and finely marked specimen. The other 

 was much lighter in colour, and with the spots not so distinct. 



Bhododendrons from Sihhim. — Mr. G. F. Wilson exhibited 

 flowers of a hybrid Sikkim Rhododendron with large rose- 

 coloured flowers. The petals were very broad and flat, measur- 

 ing 2^ to 3 inches across. Probably allied to R. Nandeo. 



Crinum capensc. — A specimen of this plant, forwarded by 

 Mr. F. W. Moore, of the Botanic Garden, Glasnevin, was interest- 

 ing, as it had been successfully flowered in the open air near 

 Dublin. The flowers were numerous, not so large as the type, 

 but fully coloured. 



Aqiulegia Stuarti. — This striking plant, with deep blue 

 sepals and white petals, was shown by the President, Sir Trevor 

 Lawrence. It is an improved form of A. gland ulosa, refined in 

 colour, very large and attractive. 



Coryanthes Wolfi. — This singular species, first flowered in 

 Europe by Mr. F. W. Moore, Keeper of the Botanic Garden, 

 Glasnevin, was referred to the Committee on account of the 

 specialised character of the flowers, which are orange-coloured 

 spotted with reddish chocolate. The hood is concave and almost 

 solid. In every other species it is helmet-shaped and hollow 

 beneath. The horns at the base of the column are very large. 

 The plant is a native of Ecuador, and grows on Cacas trees in 

 the littoral districts of the Guayas. It flowers when these level 

 lands are mostly inundated. The flower spikes are stiff and 

 upright, and not pendulous as in other species.
