84 Mr Willis and Mr Burkill, Observations on [May 15, 



Nineteen species have only one record each, and twenty others 

 have less than five records. The remaining twenty species have 

 from 5 to 40 records. 



The results are of some interest fiom the point of view of the 

 means of distribution of seeds. If we roughly classify them ac- 

 cording to the various methods employed we obtain the following 

 list: 



I. Fleshy Fruits, distributed by animals. 



Rhamnus, Pinmus, Rubus (4 species), Rosa, Pyrus, Crataegus, 

 Ribes (3), Bi^yonia, Hedera, Sambucus, Viburnum, Lonicera, Sola- 

 num, Asparagus. 



Total species 19 (23-75 per cent.), plants 1763 (44-62 per 

 cent). 



II. Burred Fruits, distributed by animals. 

 Geum, Galium Aparine, Avena. 



Total species 3 (3'75 per cent.), plants 651 (1647 per cent.). 



III. Winged and feathered fruit or seed, wind-distributed. 



Acer, Epilobvwm (2), Angelica, Heracleuni, Senecio (2), Cnicus, 

 Leontodon, Taixixacum, Lactuca, Fraxinus, Syringa, Rumex (3), 

 Ulmus, Humidus, Alnus, and the Gramineae (14). 



Total species 33 (41*25 per cent.), plants 995 (25*18 per cent.). 



IV. Seeds, &c., very small and light, wind-distributed. 

 Sisymbrium, Gerastium (2), Stellaria, Achillea, Veronica (2), 



Ur'tica, Polypodium. 



Total species 9 (11*25 per cent.), plants 425 (10*75 per cent.). 



V. Explosive mechanisms. 

 Geranium. 



Total species 1 (1*25 per cent.), plants 2 (-05 per cent.). 



This plant must have reached its place in the willow by some 

 other means, as its mechanism is not good enough to throw the 

 seed to such a height. 



VI. Plants whose means of distribution is poor or douhtfid. 

 Ranunculus (3), Barbarea, Lathy rus, Ghaerophyllum, Anthris- 



cus, Galium Mollugo, Galystegia, Nepeta, Stachys, Lamium (2), 

 Plantago, Polygonum. 



Total species 15 (18*75 per cent.), plants 115 (2*9 per cent.). 



The percentages of the species distributed in each of the 

 different ways agree fairly closely with those given by Loew.
