 Brisbane River (Leichhardt), Comet Rivei- (O'Shanesy),

 Maranoa (Barton), Burdekin River (F. v. M.), Mount 

 Surprise (Armit). The flowers are sometimes fascicled, 

 and occasionally supported by long floral leaves. Forms 

 with particularly long and narrow leaf-lobes, seemingly 

 also belonging to this species, bear much resemblance to 

 Meionectes. At the whole it is less robust than the 

 following : — 



H. aspera was originally in 1836 collected by Sir Thomas 

 Mitchell on the Murrumbidgee ; it has a w^ide range, thus 

 is known from the Upper Darling River (Wuerfel), Warrego 

 (Mrs. Cotter), Barcoo (Schneider), Charlotte Waters (C. 

 Giles), James and Finke Rivers (Kempe), Evelyn Creek 

 (A. King), Mount Everard (E. Giles), Musgrave Ranges 

 (Forrest), Eucla (Carey). Any endeavour to separate H. 

 glauca specifically from H. aspera, would prove futile ; for 

 unison the latter name is preferable. IJnder the name 

 sclopetifera a plant is separable from H. aspera, either as a 

 variety or perhaps as a distinct species, on account of its 

 verrucular catyx, which when fruit-bearing, is copiously 

 beset at the summit with narrow dilated and often simply 

 or doubly-hooked excrescences, its leaves are from linear- 

 lanceolar to broad-linear ; it is known only from Norman 

 River and Spear Creek (Th. Gulliver), and from Aramac 

 Creek (Dr. Poulton). 



H. acutangula extends to Point Sinclair ; its leaves are 

 rather flat and often somewhat denticulated. 



II. salsoloides has staminate and pistillate flowers on 

 distinct plants, as first observed by Messrs. Haviland and 

 Deane, w4io found this rare species at Double Bay, consociated 

 with Casuarina nana ; it is often only half-a-foot high, even 

 when fruiting, and then somewhat reminds of Tillaea recur va. 

 Specimens from any mountain region never came under the 

 writer's notice. 



H. Gossei was found near the Finke River (Rev. H. 

 Kempe), 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) ; occasionally the fruits are 

 tetramerous.
