 Explor. Exped.) in its smaller neither leathery nor stalked 

 leaflets and pentamerons flowers. On this apt occasion I am 

 anxious to describe another Australian vine, mentioned al- 

 ready by Captain Stokes, which yielded in its young branches 

 a pleasant acid antiscorbutic vegetable to Mr. Gregory's ex- 

 ploring party in North West Australia, viz. : — 



Cissus acetosa. 

 (Sect. Ampelopsis.) 

 Erect, not climbing, herbaceous, soon glabrous; leaves 

 pedate, consisting of from 5 to 9 herbaceous undotted 

 leaflets; the lateral ones sessile on the secondary petiole 

 and distant from the stalked middle one ; all oblong or 

 cuneate-obovate, blunt, mucronulate, entire or in front 

 minutely crenate- denticulate, beneath ■ paler ; panicle 

 compound, contracted ; petals much longer than the 

 calyx, inside dark purple ; stigma sessile ; berries ovate- 

 globose, black. 

 Stems several feet high, not shrubby, rather succulent. 

 Petioles short. Length of leaflets 4 inches or less. Stipules 

 broad triangular. Petals 1 line, berries 3 lines long. 



This remarkable plant forms the transit from Cissus to 

 Vitis, differing from the latter genus in the solution of the 

 petals, from the former in the absence of a style. 



SaPINDACEjE. 



Arytera foveolata. 



Branchlets, petioles and panicles more or less covered 

 with a rust-brown velvet ; leaflets 4-6 on short stalks, 

 ovate or lanceolate-ovate, blunt, entire, or repand-den- 

 tate, glabrous, on both sides of almost equal colour, be- 

 neath at the base of each lateral nerve slightly bearded 

 and furnished with a foveole ; flowers small in wide 

 racemose panicles; anthers almost velvety, cordate-ovate; 

 carpels 2-4, beyond the base disconnected, broad-ovate, 

 turgid, blunt ; valves thick, coriaceous, outside velvety, 

 inside glabrous ; seeds nearly black, turgid, broad- ovate, 

 perfectly involved in the arillus. 



In the forests of Moreton Bay. Hill and Mueller. 



A tall tree. Leaflets generally alternate, thin-coriaceous, 

 2-4 inches long, \-\\ broad, with spreading nerves and nu- 

 merous veins. Calyx shorter than one line, 5-cleft. Sta-
