544 NOTES AND EXHIBITS. 



axils of the leaves, and in this example one of the pair, when in 

 fruit, is much reduced in size, the other remaining normal. 

 Where the fruit is beset with two adventitious buds, one of 

 them is sessile and the other pedicellate, and they are placed 

 opposite to each other. The adventitious flowers had in 

 several cases produced fertile fruits. — Sonchus oleraceus Linn., 

 (Pennant Hills; T. Steel; November, 1913) showing foliar, 

 and floral, spiral contortion. The stem-leaves, and bracts of 

 the involucre are produced into elongated, spirally contorted 

 points. — Epacris reclinata Cunn., three forms of this Blue 

 Mountain species with differing characteristics: the typical 

 form, reclining in the crevices of dripping rocks; a second form, 

 decumbent on the top and sloping sides of partially dry rocks; 

 and a third, erect form growing on open hillsides. The foliage 

 of the typical form is soft and pilose, the plants are few-flowered, 

 and the corolla, as described in the Fl. Austr., is uniformly red. 

 In the decumbent form, the foliage is harsher and less hairy, the 

 flowers are more numerous, and the corolla-lobes are pale. In the 

 erect form, the hairiness has almost disappeared, the branches are 

 very floriferous, and the pale corolla-lobes have become white, 

 closely approaching those of the particoloured E. longiflora Cav. 

 — Hakea propinqua Cunn., (Blackheath; A. A. Hamilton; Sep- 

 tember, 1914) the colour of the flowers of plants of this species 

 growing on the higher elevations of the Blue Mountains is an 

 attractive, bright yellow. Coastal examples from the National 

 Park and Hornsby show the customary white flowers. The 

 yellow colouring of the flowers of this species is also noted (by 

 the collectors) on specimens in the National Herbarium from 

 Cox's River (J. H. Maiden and R. H. Cambage; October, 1904). 

 The mountain specimens have shorter and stouter leaves, the 

 flowers are more crowded and on shorter pedicels, and the fruits 

 are smaller than those of the coastal plants. — Kennedy a mono- 

 phylla Y ent. ^(Har-denbergia) showing leaf -variation. The leaves 

 vary in shape from linear to rotundate, their apices are acute, 

 obtuse, apiculate, and emarginate, and their bases ovate, cordate, 

 or hastate. Dimensions: 4J x If in., 4 x Jin., 3 x 2in., 2| x fin., 

 2 X 1 J in., 2J X ^ in., 1x1 in., 1 J x ;J in. — Fersoonia lanceolata
