foliosa, with large leaflets ; var. intermedia, with very small ones ; and 

 the ordinary form, with none at all. Natives of New Zealand. Apera 

 arundinacea, Hook., the " Pheasant's-tail " Grass of the island of New 

 Zealand ; the autumn tints of red and brown are very pronounced. 

 Hypoxis hemcrocallidca {— H. elata, Bot. Mag.). A point to be observed 

 is the circumscissile dehiscence of the ovary. It has been grown in the 

 open at Dublin for seven years. Narcissus Tazetta, a variety always 

 blossoming in November and December in the open air, but near a warm 

 plant-house. It is remarkable for the great length of stem and foliage. 

 Laurelia aroynatica, the "Chilian Sweet Bay." The leaves are highly 

 aromatic if bruised. It makes an open-air shrub at Wicklow 25 feet 

 high, and is useful as a pot or tub plant in a conservatory. The genus 

 has only two species — one in Chili, the other in New Zealand, indicating 

 (with Fuchsia) a former connection between these places ; it belongs to 

 the order MonimiacecB. Azolla filiciiloides has lived for years in muddy 

 tanks ; if introduced in a pond it is difficult to eradicate, from its hardy 

 nature and great powers of multiplication. Acacia melanoxylon (?), 

 showing compound blades upon several of the phyllodes, an unusual 

 feature in Australian species. Parochetus couwiunis, Indian Shamrock," 

 remarkable for the perfectly straight peduncles, which become strongly 

 bent in the fruit, as if to bury the legumes like Arachis. 



Scientific Committee, November 26, 1901. 



Dr. M. T. Masters, F.R.S., in the Chair, and twelve members present. 



Plasmodium, remedies for. — With reference to lime as a remedy for 

 clubbing, Mr. Houston observed that with superphosphate the disease 

 tended to increase, as it was of an acid nature ; but the converse took 

 place with basic slag, as it was alkaline, and more destructive to the slime 

 fungus. 



Cypripedium insigne. — Mr. Odell exhibited a blossom having the two 

 basal sepals distinct, instead of coherent, as is normally the case. 



Daphne fasciated. — Rev. W. Wilks showed a very marked example of 

 this well-known peculiarity. It has lately been stated that the imme- 

 diate cause of incitement to fasciation is the presence of an abundance of 

 food in an easily assimilable condition. 



Australian Bkubarb. — Mr. Sutton regretted that be was unable to 

 show samples, as it has again been cut down by the frost. Though 

 flourishing at this season of the year in Australia, it has not yet become 

 so acclimatised to frosts in England as to be available as a winter crop. 



Armeria plantaginea, foliaceous. — Mr. Bowles exhibited a specii^en 

 in which the bracts had elongated into leaves, as not infrequently occurs" 

 in Plantains. 



Lily Bulbs Diseased. — Mr. Bowles also brought bulbs and foliage of 

 the white Lily badly attacked by Botrytis, an unusual occurrence at this 

 season of the year. 



Ligji Aloes. — Dr. Cooke showed specimens from India of the inner 

 bark of Aquilaria Agallocha, smoothed for the purpose of being written
