27/3/09) showing fasciation of the stem and foliar prolification of 

 the inflorescence. A whorl of reduced leaves is noticeable on the 

 faciated stem, below the dilated, abortive ovary, upon which a 

 circlet of sessile, atrophied buds, with foliaceous calyces, is seated. 

 — Chrysanthemnm frutescens L., (W. M. Carne; Sydney Botanic 

 Gardens; 14/3/14) showing extrafloral prolification; virescence 

 of the tubular florets, which are much enlarged, and have their 

 reproductive organs suppressed, and of the ligulas of the ray- 

 florets; leafy branches, bearing buds, spring from the axils of the 

 floral bracts, a capitula of floral bracts ascending from one of the 

 tubular florets, and a ray-floret of an otherwise perfect flower 

 which has developed its tube at the expense of the ligula. Green 

 flowers, a result of the development of chlorophyll in place 

 of the colouring matter proper to the flower (virescence), have 

 been unusually prevalent in the coastal area, especially among 

 cultivated Asters, during the past exceptionally dry Spring and 

 Summer, furnishing additional evidence in favour of the generally 

 accepted theory that droughty conditions are largely responsible 

 for this habit.— A series of leaves of Isopogon ane^nonifolius 

 R.Br., (A. A. Hamilton; Cook's River; September, 1913) showing 

 the xerophytic character of reduction of leaf-surface, owing to 

 unfavourable conditions. The plant, from which the leaves were 

 taken, was growing on a plateau overlooking Cook's River at 

 Undercliffe, in a shallow depression, with a few inches of shale 

 covering the rock, which, after rain, becomes a pool of stagnant 

 water. — Acacia longifolia Willd.,(A. A. Hamilton; Springwood, 

 Went worth Falls, and Leura; November, 1913) showing leaf- 

 variation, from linear to ovate-lanceolate; obtuse, acute, to long 

 acuminate; straight to falcate. Some measurements are, 11 J x | 

 in., 8x|in., 6J x IJin., 6 x |in., 5^ x Jin., 3 J x |-in., 1\ x ] in. — 

 Hakea dactyloides Cav.,( A. A. Hamilton; Cook's River, December 

 1913; Valley Heights, January, 1914) showing leaf- variation in 

 breadth, contour, and texture. 



Mr. Fletcher showed a number of branches of Lantana Camara 

 Linn., from Hunter's Hill, exhibiting the cohesion of opposite 

 leaves, basally and upwards to a varying extent. Before the 

 bountiful rains, which began in February, the plants were suffer-
