Imperfectly Known Australian Plants. 23 



In the Brigolow Scrubs of East Australia, as far north as 

 the Burdekin River. 



A shrub several feet high, with compressed angulate 

 branchlets. Leaves alternate or fasciculate, pale-green, 4-8 

 lines long. Calyx in aestivation valvate, one line long. Pe- 

 tals yellowish- green, as long as the calyx, with two ovate 

 denticulate scales, \ line long, at the base. Anthers one- 

 sixth of a line. Styles one line long. Drupe succulent, half 

 an inch long. 



The nearest related species seems E. hypericifolium. Its 

 wood probably yields a dye like that of many of its congeners. 



Hippocrates. 



Hippocratea barbata. 



Glabrous, climbing, leaves on rather short petioles, char- 

 taceous, ovate, rarely lanceolate, blunt, repand-crenulate, 

 much longer than the cymes ; petals yellowish, lanceo- 

 late, five or six time longer than the calyx, inside above 

 the middle bearded ; anthers four-lobed. 



On the banks of rivers near Moreton Bay. Hill and 

 Mueller. 



A tall climber. Leaves from 1^ to 3 inches long. Flowers 

 scented, with 5-6 petals. Anthers yellow. Style conical- 

 subulate, green. 



The plant is allied to Hippocratea obtusifolia and pauci- 

 flora, particularly in respect to its large flowers, but cannot 

 be identified with any described Indian species. It is the 

 only representative of the order hitherto discovered on this 

 continent. 



Vinifers. 

 Cissus opaca. 

 (Sect. Ampelopsis. ) 

 Shrubby ; leaves palmate, often on long stalks, with 3-5 

 leaflets, which are herbaceous, oblong, or cuneate-lance- 

 olate, rarely ovate or linear, entire or sometimes in front 

 toothed, sessile, opaque, beneath glaucous; umbells in 

 paniculate cymes ; corolla three times longer than the 

 calyx, green ; style short : stigma depressed ; berries 

 black. 



In the Brigolow scrub of Eastern Australia. 



A tall vine, generally glabrous, sometimes slightly downy. 



It differs from Cissus Australasica (Transact. Phil. Soc.
