RECORD OF A REMA.RKABLE HALORAGIS FROM 

 NEW SOUTH WALES. 



By Baron von Mueller^ K.C.M.G., M.D., Ph.D., F.R.S, &c. 

 Haloragis monosperma. 



Erect, quite glabrous, leaves rather small, on numerous abbre- 

 viated branclilets crowded, all opposite linear-lanceolate, almost 

 sessile, nearly flat, scantily denticulated towards their summit ; 

 floral leaves also opposite, gradually shorter, but only the uppermost 

 reduced to bracts ; flowers solitary or two together in the axils of 

 the upper leaves, the terminal and sub-terminal flowers spicate ; 

 all on very short stalklets ; lobes of the calyx four, deltoid ; petals 

 boat-shaped, smooth ; anthers much elongated, very narrow ; 

 styles four ; stigmas pyramidal, semi-ovate, not downy ; ovary 

 four-celled ; fruit almost hemiellipsoid, quadrangular, considerably 

 longer than broad, slightly tubercular, one-seeded ; pericarp crusta- 

 ceous, under the adnate calyx-tube eight furrowed. 



On heaths at the western side of ranges near Braidwood, at an 

 elevation of about 3,000 feet ; W. Bauerlen, who from the same 

 region brought Boronia rhomhoidea, B. pilosa, Miihlenheckia steno- 

 2)hylla. Pomaderris phylicifolia, Didiscus humilis and Uncinia 

 tenella. Height of the plant above one foot ; branchlets quadran- 

 gular ; majority of leaves varying in length between | and f inch, 

 somewhat concave, more crowded than those of most other species. 

 Fruit bearing calyx fully one-sixth of an inch long ; seed central. 

 The characteristic of the one-seeded fruit is exceptional in the 

 genus, but may not be absolutely constant, as the ovary is four- 

 celled. This species is in some respects allied to H. lanceolata^ 

 but must systematically be placed near H. salso/oides, from which 

 it differs in being of much more roVjust growth and perfectly 

 glabrous, in more numerous much larger and particularly broader 

 leaves, and perhaps also in form and structure of the fruits, that 

 of H. salsoloides remaining still unknown. 



The same collector, while under engagement to the writer, has 

 afforded the opportunityof recording most of the following plants as 

 recently traced to far southern localities in New South Wales : —
