H. Gossei was found near the Finke River (Rev. H. K e m p e) , at 

 Ularing (Young), at Alice Springs (Ch. Giles), in the glen of Palms 

 (E. Giles), on the Mulligan River (Cornish). Field River (Winnecke), 

 Nickol, Cane and Ashburton Rivers (Forrest), Exmouth Gulf (Carey); 

 occcasionally the fruits are tetramerous. 



H. trigonocarpa was obtained at the Gascoyne River by the Hon. 

 John Forrest, and a variety with linear leaves at Lake Austin by 

 Mr. H. S. K i n g. 



H. monosperma forms somewhat leafy spikes to the length of three 

 inches ; according to specimens sent by, Mr. G. Mac R a e s, the petals 

 are almost white , gradually pointed , not prominently keeled , and 

 lully to one-quarter inch long; thus, as far as blooming is concerned, 

 it provee the most conspicuous among its many congeners, so far 

 approaching the Loudonias, to which it bears similarity also in tall 

 growth, while it verges to the serpiculas in carpologic characteristics, 

 but the fruit of a few other species may ripen also only one seed, 

 notably those of H. titragyna in India, as pointed out by Mr. C. B. 

 Clarke in Sir Joseph Hooper's Flora of British India, IL, 481, and 

 as noted already by 0. König. 



H. trifida will likely prove a Myriophyllum , while the H. cyathi 

 flora, to judge from Fenzl's descriptive notes , may possibly be a 

 gyrostemonous plant. 



In concluding these short references to Australian Halorageae, it 

 might yet be observed that the genus Meionectes can no longer be 

 niaintained, after what we more recently have learned of the numerical 

 inconstancy of the floral divisions in several species of Haloragis. 

 Indeed , Meionectes became impaired in its generic position , already 

 by the discovery of a dimerous species as well of Loudonia as of 

 Myriophyllum, and Bentham also noticed already that bis Haloragis 

 tennifolia was closelj' connected with Meinoctes Brownii. In that 

 plant being placed unter Haloragis now , the generic name serves 

 aptly for specific signification. 



H. digyna is now known also from Israelite Bay (Miss B r o o k e), 

 Eucla (Oliver), and Lake Bonney (F. v. M.); its calyx-lobes occur 

 sometimes of deltoid form, and they number not rarely like the petals ; 

 styles and fruit-cells three or four; but, though the fruit may be 

 quadrangular , it is only oue-or two-seeded. From H. digyna cannot 

 be held apart as a species H. mucronata. Sometimes the fruit 

 produces callous extrusions, thus far rerainding of the inner sepals of 

 Rumex, the margins of the petals turn sometimes bluish. 



H. pityoides occurs on the Arrowsmith River (F. v. M.); it is 

 Drummond's plant 706, the calyx-lobes are almost deltoid, the fruit 

 is sometimes densely beset with hairlets. H. pusilla is closely allied 

 to the foregoing. 



Plucheaconocephala. 

 (Eurybia conocephala, F. v. M. in the Transactions of the Victorian 



Institute, 1 — 36.) 

 Dwarf-shrubby, much branched ; leaves small , obovate or spatular- 

 cuneate, flat, entire, as well as the branchlets grey velvet downy; 

 flower-heads sessile, singly, terminating branchlets iniperfectly dioecious ; 

 involucre at first almost hemiellipsoid-cylindrical , at last obverse 

 conical; involucral bracts in several rows, rounded-blunt, near the 

 Upper end somewhat velvet-downy and fringy-ciliate , the outer bracts 

 abbreviated , the lowest verging to an oval form , the inner bracts 

 gradually elongated , narrowly elliptical-cuneate , and finally beyond 

 the middle recurved; receptacle minute ; flowers few within each 

 involucre and extending considerably beyond it ; corolla of the perfect 

 staminate flowers slightly dilated above the middle, those of the most 

 developed pistillate flowers thinly cylindrical , the five lobes of either 

 rather long, comparatively narrow, hardly spreading; style glabrous ; 

 achenes narrow-cylindrical , hardly angular, quite glabrous; bristlets
