Imperfectly Known Australian Plants. 29 



capsule trivalved, one- celled, large ; seeds yellow, many 

 along each of the imperfect septa. 



In dry plains and rocky declivities of Arnhem's Land. 



A tall shrub or small tree, with generally pendulous 

 branchlets. Leaves pale green, li-3 inches long, one-nerved. 

 Panicles axillary, or terminal, often not as long as the leaves; 

 secondary peduncles angular, generally cymose. Pedicels 

 about as long as the calyx, with deltoid lanceolate bracteoles 

 at the base. Lobes- of the calyx | line long. Petals pale 

 greenish-yellow, smooth, \\ line long. Filaments measuring 

 only h line. Anthers almost white. Ovary globose-ovate, 

 imperfectly three-celled. Capsule ovate or nearly globose, 

 1-1^ inch long, shining yellow, with three slight furrows, 

 smooth. Dissepiments very narrow, with eight or less seeds 

 to each, which are ovate, 3-4 lines long, and perfectly involved 

 in a beautifully red arillus. Testa wrinkled-papillose. 



Denhamia heterophylla. 



Branchlets almost terete ; leaves ovate or lanceolate, acu- 

 minate, entire or acutely toothed, or both pages of equal 

 colour, provided with conspicuous petioles ; flowers pa- 

 niculate ; filaments as long as the anthers ; capside 3-5- 

 valved ; seeds black, one or a few on each septum. 



On scrubby ridges from the Gilbert River to the Burdekin 

 River. 



Similar in almost every respect to the preceding species. 

 Bark grey, wrinkled. The leaves are as variable as in some 

 of the Capparis species, resembling in the young plants those 

 of Xylomelum. Hence this tree occurs under that name in 

 Dr. Leichhardt's journal, and in D. O, prod, xiv., p. 422, ad- 

 not. Capsule pale orange, arillus red. 



Denhamia oleaster. 



(Melicytus ? Oleaster, Lindl. in Mitch. Trop. Austr., p. 383.) 



Branchlets nearly terete ; leaves linear- or narrow-lanceo- 

 late, tapering into a short petiole ; flowers racemose ; 

 filaments longer than the anthers; style short, cylindrical. 



On the Balonne Biver. Sir Th. Mitchell. 



A shrub several feet high. Leaves pale green, 1^-2^ 

 inches long, ^-\ inch broad, acute. Bacemes on short pedun- 

 cles. Lobes of the calyx semiovate, ciliolate, \ line long. 

 Petals white, nearly 2 lines long. Filaments exceeding
