and often downward-bent appendages at the angles of the fruit in the 

 legitimate species do not occur in any of the Australian specimens 

 seen by the writer of these remarks ; besides , the leaves are usually 

 longer and narrower, also more decurrent into the stalk , while the 

 floral leaves are more reduced to bracts; indeed the Australian plant 

 verges closely to H. serra, but has four styles, as also a four-celled 

 and four-seeded fruit ; either as a variety or as a distinct specific form 

 it might be distinguished under the name exalata. 



H. cordigera has been traced to the Serpentine River (F. v.M.); the 

 fruit is shorter than the calyx-lobes, and not rarely bearing hairlets. 



H. scoparia bears a fruit roundish-ovate , compressed , beyond the 

 base upwards slightly quadrangular, much longer than the calyx-lobes, 

 two-celled and two-seeded. 



H. hexandra was seen by the writer of these lines near King George 's 

 Sound and the Shannon ; the leaves, when fresh. are carnulent. 



H. odontocarpa extends to the Gascoyne River (F or res t), to Youldeh 

 and Ondahinna (Tietkens), to the Elizabeth River (Giles), to the 

 Lachlan River (T u c k e r). 



H. serra ranges to the Clarence River (Beck 1er), Hunter River 

 (Miss H. Carter). 



H. exalata was obtained at Mount Dromedary (Reeder), on the 

 Burnett River (Hely); the leaves are paler beneath ; the stigmas are 

 not conspicuously bearded. 



H. rotundifolia varies in height from one-half to four feet ; it is 

 perennial, like nearly all its congeners ; we know this plant now from 

 Karri-Dale (Walcott), the Shannon, the Collier, the Preston, and the 

 Serpentine Rivers (F. v. M.). The leaves are sometimes not at all 

 larger than those of H. micrantha, to which species this plant bears 

 some resemblance in the capillary branchlets of the panicle and in 

 the minute fruits. 



H. scordioides has an irregularly wrinkled, truncate-globular, some- 

 what quadrangular fruit, not much longer than the calyx-lobes. 



H. micrantha has been sent from Walcha by Mr. Crawford. 



H. depressa occurs on Mount Field, at elevations from 3 to 4000 feet, 

 also on Mount Kosciusko (F. v. M.). 



H. teucrioides has been found in New England (C. Stuart), in 

 Yorke's Peninsula (Tietkins), near Streaky Bay and Fowler's Bay 

 (Mrs. Richards), in Kangaroo Island (Prof. Täte). 



H. titragyna reaches the Tweed (Hickey), the Dawson River 

 (Ü'Shanesy), and the Darling Downs (Law). 



H. liptotheca is contained in our collections now, also from King's 

 Sound (Hugham), Yeldham Creek (Ar mit), Trinity Bay (Fitzalan). 

 H. acanthocarpa, to which Bentham joins H. liptotheca, seems rather 

 to constitute a form of H. titragyna, to which latter would, early in 

 the Century, be much more readily accessible to Brongniart than 

 the intra-tropical H. liptotheca. 



H. elata extends to the Castlereagh River (WooUs), Macquarie 

 River (B et che), Darling River fBurkitt), Lachlan River (Tucker), 

 Gawler Range (Ryan), Condamine River (Hart mann), Bogan 

 (Morton), Dawson River (O'Shanesy). Contrary to wliat the specific 

 name would imply , this plant seldom attains a height of two feet ; 

 some of the leaves assume occasionally quite a lanceolar form. 



H. rudis is often erect, but seems never a tall species; the branchlets 

 are remarkably robust; the leaves have a particularly thick pale 

 margin. 



H. nodulosa was gathered by the writer at the Greenough and Irwin 

 Rivers; eastward, it extends to Israelite Bay (Miss Brooke), and 

 Esperance Bay (Dem pst er). 



H. paniculata occurs on the Collier, Preston, and Blackwood Rivers 

 (F. V. M.).
