Collected by Mr. A. H. S. Lucas, late President of this Society, 

 " in a wild gully near Gordon, Port Jackson," November, 1908. 



An erect bushy shrub under 3 feet high, smooth and glabrous 

 in all its parts; the branches quadrangular and slight!}^ winged 

 by the decurrent bases of the leaves, leafless in the lower part 

 but marked by scars of the fallen leaves. Leaves opposite, 

 lanceolate, narrowed towards the base, but sessile and narrowly 

 decurrent, 3| to 5 cm. long except the upper shorter floral leaves, 

 irregularly serrate, the teeth with reddish callous tips. Flowers 

 solitary, shortly pedicellate in the axils of the upper leaves, or 

 tet-minal on short axillary leafy shoots, the two bracteoles a short 

 distance removed from the base of the cal3^x, minutely denticu- 

 late. Calyx-tube smooth, without any of the asperities so common 

 in the genus, but with four longitudinal wings geneiall}^ more or 

 less undulate; calyx-lobes broadly triangular, alternating with the 

 wings, rather above half as long as the tube. Petals 4, white, 

 linear, about 12 mm. long and 4 mm. broad, bluntly keeled, alter- 

 nating with the calyx-lobes. Stamens 8, nearly as long as the 

 petals, the filaments less than J the length of the erect anthers; 

 anthers linear, 2-celled, opening longitudinally. Styles 4, about 

 1^ to 2 mm. long, with papillose stigmas. Ovarium quite adnate 

 to the calyx-tube, 4-celled, with a pendulous ovule in each cell. 

 Pruit (not seen quite ripe) elliptical, smooth, 5 to 6 mm. long 

 without the calyx-lobes, conspicuously 4- winged, the wings about 

 1| mm. broad, 4-celled. Ripe seeds not seen. 



This is the most handsome species of a genus consisting 

 generally of insignificant looking plants with no claim to beauty. 

 The smooth gloss}-- foliage and the comparatively large white 

 flowers make it quite worth cultivating. It is rather difficult to 

 find its exact position in the system, as it differs so essentially
