Mountain, Belfast. This is a rare Irish plant and has only been 

 found hitherto in Kerry and Cork. 



The Rev. C. H. Waddell, M.A., B.D., then gave an interesting 

 lecture on "The Incompletes (Goosefoots, Knotweeds, &c.), and 

 the new Classification of Engler." 



An outline was given of the history of the classification of 

 Flowering Plants, and the various systems described. That of 

 Bentham and Hooker has been universally adopted in this 

 country for many years. Its chief drawback is that plants 

 which do not possess a fully developed perianth are lumped 

 together in the group Incompletes at the end of the series of 

 Dicotyledons. 



The new system of Engler which is more in accordance with 

 later advances in Botany was described. It has been adopted 

 generally on the Continent, and in some new works in England 

 and America, and is likely to take the place of the more familiar 

 classification. Engler dispenses with the group Incompleted 

 altogether, and finds places for the members of it among the 

 other orders to which they are most nearly related. 



Brief descriptions were given of the Goosefoots, Knotweeds, 

 Willows, &c, and of the structural particulars which link them 

 with other natural orders. 



"ROCK GARDENS, NATURAL AND ARTIFICIAL." 



The fifth meeting of the Winter Session was held in the 

 Museum, College Square North, on the evening of the 1 6th 

 March, — the vice-president, Mr. VV. H. Gallway, in the chair. 

 Mr. R. Lloyd Praeger, B.A., B.E., M.R I. A., read a paper on 

 " Rock Gardens, Natural and Artificial," to a large and represent- 

 ative audience. The lecturer said during recent years the 

 cultivation of Alpines and rock plants had been growing in favour, 

 so that now a piece of rockwork planted with these denizens of 

 the hills was an almost necessary adjunct to any garden of a
