Jenner, coming up in the same place in the garden for four 

 successive seasons. — The " CupHowered Foxglove," Digitalis 

 purpurea Hort. var., (Sydney Botanic Gardens; October, 1914; 

 E. N. Ward) showing arrested growth accompanied by petalody 

 of the calyx. The suppression of the internodes of the stem has 

 forced the flowers into a circlet, the corolla-tubes are ruptured, 

 and the segments laid open, side by side. The sepals have 

 developed a degree of petalody in most of the flowers. This 

 growth has been "fixed" bv Sutton &, Co., the well known 

 British nurserymen, who are also responsible for the vernacular 

 name. Plants grown from seeds in the Botanic Gardens, Sydney, 

 yielded 90% of "Cup "-flowers. — Trifolium pratense L., [Sydney 

 Botanic Gardens (cult.); W. M. Carne; November, 1914] showing 

 extra-floral prolification of the inflorescence, accompanied by 

 virescence. — Boronia anertionifolia A. Cunn.,(Newnes Junction; 

 A. A. Hamilton; September, 1914), two examples illustrating 

 the effects of environment; one taken from a bush, 4 ft. high, 

 growing in a sheltered position, with access to a plentiful water- 

 supply; the other from a sterile ridge, a coarse harsh plant, 



6 inches high. The variation in the two forms is so marked as 

 to create a difiiculty in recognising them as the same species 

 from dried herbarium-material. — Examples of dimorphic foliage 

 in Acacias: A.longifolia Willd., A. suaveolens Willd., A. myrti- 



folia Willd., and A. linifolia Willd. In the first two, the lower 

 leaves are much larger than the upper ones, the change occurring 

 in each case abruptly; in A. myrtifolia the position is reversed, 

 the lower leaves being the smallest ; and in A. linifolia, the 

 dimorphic condition occurs on two separate branches springing 

 from the same base on the stem. — Acacia ruhida Cunn., (Glen- 

 brook Lagoon; A. A. Hamilton; October, 1914), showing fructi- 

 fication in the juvenile (bipinnate) foliage stage. Attention was 

 drawn to a similar occurrence on plants from Woodford, by Mr. 

 R. H. Cambrge, in the Journ. Proc. Roy. Soc. N. S.Wales, xlviii., 

 p. 136. — Leaf-variation : Persoonia salicina Pers., the leaves vary- 

 ing in shape from rotundate to oblong-lanceolate, straight to 

 falcate, and with acute or obtuse apices. Measurements: 8x2^, 



7 X IJ, 6x3^, 5 X |, 4 J X 3, 3^ X 2, 2J X 1 inches. Acacia myrti-
