626 NOTES AND EXHIBITS. 



concerning the life-history of the red-clover rust; he suggests 

 that it is an heteroecious species; and proposed the name 

 TJ. fallens for it. Numerous writers, however, including Miss 

 Howell [who has shown that the rust on red and on white 

 clover {T. repe7is) is identical, and that the uredo- and teleuto- 

 spores can be produced from the secidium which appears early in 

 the summer] have regarded the rust on perennial red clover as U. 

 trifolii. Specimens were submitted to Mr. C. C. Brittlebank, of 

 Melbourne, who has compared the uredospores and secidiospores 

 of the Perennial Red Clover with those of U. tri/olii-repentis 

 Tirv., and he states that he cannot separate them. — Fresh flower- 

 ing-specimens of Callistemon lophanthus Sweet, and C. lineari- 

 folius DC, in cultivation at the new Zoological Gardens at 

 Taronga Park, under the direction of Mr. A. S. Le Souef. The 

 former is quoted as a synonym by Bentham under C. salignus 

 var. hebestachyus, but seems quite distinct from any of the forms 

 of C. salignus. G. linearifolius DC, is also quoted by Bentham 

 under C rigidus. These were both omitted when the key to 

 the species of Callistemon, in Illustrations of New South Wales 

 Plants, Part 3, p. iii. (1911), by J. H. Maiden, was drawn up; 

 but abundant material, which has since been received and 

 studied, seems to warrant the view that both should be raised to 

 specific rank again. Fresh specimens of an undescribed species 

 were also shown, which were raised from seed obtained from 

 plants on the Nattai River, via Hill Top. A fine series of fresh 

 flowering-specimens of C. lanceolatus DC, C. linearis DC, C. 

 rigidus R.Br., C. speciosusT)C., C. phoeniceus Lindl., C. rugulosus 

 DC, (C coccineus F.v.M.), C. pinifolius DC, and two forms of 

 C. hrachyandrus Lindl., were also shown for comparison with 

 the above, and C. acuminatus Cheel, (together with herbarium 

 specimens of the latter, previously collected at Bulladelah, 

 N.S.W., from a new locality between the 15-16 mile post, Galston 

 Road, Hornsby; W. F. Blakeley; November, 1914).- A series of 

 specimens of Helichrysum diosmifolium Less., collected at Hill 

 Top, within a few yards of each other, showing flowers varying 

 in colour from pure white on some plants, through pale pink to a 

 very rich, deeper pink on others.
