162 NOTES AND EXHIBITS. 



Bean ") is an annual about 2 ft. 6 in. high; whereas C. gladiata, 

 which is known as " Red Bengal Bean," or sometimes " Sword 

 Bean," is a very vigorous climber of perennial habit, according to 

 Mr. B. Harrison, of Burringbar, Tweed River, —Mr. Cheel 

 showed, also, specimens of an introduced plant, known in Europe 

 as the "Caltrop-like Medick '" {Medicago truiicahda Gsiertn., = M. 

 tribidoides Lam.), from the Scone and Yanco districts, which 

 was an undesirable plant in sheep-country, on account of its 

 harsh, spiny fruits. 



Mr. G. H. Halligan exhibited, in quantity, examples of an 

 undetermined Amphipod, which after rain, and with the wind 

 in a certain direction, were to be found, regularly, strewn over 

 the floor of the porch of his house at Hunter's Hill. As his 

 garden was kept in order, and there was nothing out of the 

 ordinary in the way of cover for the animals, he was at a loss to 

 know how they came to be so abundant; and he asked for an 

 explanation of their occurrence. 



Mr. Fletcher exhibited an additional set of specimens illus- 

 trating the cohesion of opposite leaves in Lantana Camara L. 

 A very complete gradational series had been obtained showing 

 the results of {a) temporary adherence of the petioles only, fol- 

 lowed by separation, but bringing about the extinction of the 

 shoot; (6) incomplete fusion of the petioles on one side, accom- 

 panied by coherence of one margin of each leaf, sometimes allow- 

 ing of the escape of the shoot through a chink, but more often 

 extinguishing it; (c) complete cohesion of the petioles resulting 

 in the smothering of the shoot, accompanied by the cohesion of 

 more or less of both margins of the leaves; {d) cohesion of portion 

 of the underside of each of two leaves, brought about partly by 

 a twisting of one of the petioles; and (e) cohesion of the petioles 

 of one pair of opposite leaves and of that of one leaf of the pair 

 next below, accompanied by cohesion of both margins of one leaf 

 with one margin of each of the other two leaves involved. 



The Chairman invited discussion on Mr. Andrews' paper on 

 "The Development of the N.O. J/^/r^acece " (Proceedings, 1913, 

 p.529). Mr. Fletcher, Dr. J. R. Dixon, and Mr. Tillyard took 

 part in the discussion; and Mr. Andrew^s replied.
