NOTES FROM THE BOTANIC GARDENS, SYDNEY. 



No. 12. 



By J. H. Maiden and E. Betche. 



(Plate lxix.). 



RUTACE2E. 



Boronia Deanei, n.sp. 



Gregarious* in swamps between Clarence and Wolgan, Blue 

 Mountains (H. Deane; October, 1906). 



An erect strong- smelling shrub, about 2£ to 3 feet high, 

 perfectly glabrous in all its parts. Leaves simple, nearly erect, 

 and rather crowded, semi-terete, mostly i to \ of an inch long, 

 obtuse, smooth on the flat inner face, somewhat warty from the 

 prominent oil-glands on the rounded back. Flowers terminal, 

 solitary on a very short and thick, almost turbinate peduncle, or 

 in threes, or occasionally one or two in the axils of the next pair 

 of leaves, the pair of bracts on the base of the peduncle entirely 

 leaf-like. Calyx-lobes triangular, acute. Petals imbricate in 

 bud, red, at the most thrice as long as the sepals, not much 

 spreading in the specimens seen, so that the flower has a not fully 

 opened appearance. Sepaline stamens slightly longer than the 

 petaline ones; filaments quite glabrous, but the upper part of all 

 covered with irregular acute excrescences; anthers not apiculate. 

 Disk thick and somewhat warty. Style short, with a small 

 capitate stigma. Ripe fruits and seeds not seen. 



A very good species, sharply distinguished from all described 

 Boronias. In position it comes next to B. parviflora Sm., but 

 the habit and the leaves are totally different. The colour of the 

 flowers varies from white to deep pink. 



* There aie acres of it, to the exclusion of almost any other plant.
