NOTES AND EXHIBITS. 435 



Mr. A. A. Hamilton exhibited (1) a specimen of Pterostylis 

 qrandiflora R.Br. [N.O. Orchideae], from the Federal Pass, 

 Katoomba (April, 1908), with a terete foliaceous bract about 1 in. 

 long, springing from the base of the upper stem-leaf, a character 

 not mentioned in descriptions; the examination of specimens in 

 the National Herbarium, Botanic Gardens, disclosed an example 

 from Kunajong Heights with a similar bract, and one from 

 Cook's River with the bract partially developed — (2) Specimens 

 of Baeckea crenulata R.Br. [N.O. Myrtacese] from Mt. King 

 George (J. Gregson; January, 1908), Woodford (J. H. Maiden; 

 January, 1899), and Leura (A. A. Hamilton; December, 1907), 

 showing that this plant, hitherto recorded from the coastal dis- 

 tricts, has a wide range on the Blue Mountains. — (3) A specimen 

 of Paspalum brevifolium Fliigge, from Cook's River (A. A. Ham- 

 ilton; February, 1908) described in the ' Flora Australiensis ' as 

 with "Spikes or panicle branches 2 or rarely 3"; whereas it was 

 the rule rather than the exception for plants in the patch, from 

 which the specimens exhibited were taken, to have 3-6 spikes.
