XLV. HALOKAGE^. * 473 



2. HALORAGIS, Foist. 



(Cercodia, Miirr, ; Goniocarpus, Kcen^ 



Calyx-tube or ovary with as many or twice as many nerves as lobes, those 

 alternating ^.vith tlie lobes occasionally expanded into angles or wings ; lobes 4, 

 rarely 3 or abnormally 5, sliort. Petals as many as calyx-lobes, induplicatc and 

 boat-shaped or hood-shaped, deciduous, often wanting in female flowers. Sta- 

 mens twice as many as petals or fewer, those opposite the petals and enclosed 

 in them always present in complete or male flowers, one or more of the alter- 

 nate ones occasionally wanting, and female flowers usually without any i anthers 

 oblong or linear, deciduous ; filaments short. Ovary 2- to 4- or rarely 

 5-celled, with 1 pendulous ovule in each cell ; styles short and thick, stigma- 

 tic at the top, often plnmose in the female flowers. Fruit a small, 2- to 4- 

 or rarely 5-celled drupe or nnt, the adnate calyx either smooth or variously 

 ribbed, angled, winged, or muricate. — Herbs or undershrubs, glabrous sca- 

 brous or hispid. Leaves alternate or opposite, entire toothed or lobed. 

 Flowers small, solitary of several together in the axils of the floral leaves or 

 bracts, forming leafy or leafless racemes, either simple or in a branching ter- 

 minal panicle. Pedicels usually very short, with two small opposite often 

 deciduous bracteoles under the flower. 



The genus is chiefly Australian, but a few species are also found in New Zealand, ia 

 Eastern A«ia, in S. Afrii^a, and extratropical S. America. Of the 36 Austrahau species. 1 

 extends to New Zealand and the island of Juan Fernnndez, 2 to New Zealand and Eastern 

 Asia, I to New Zealand only, the remaining 32 arc endeniic. The characters derived from _ 

 tbe ribs and wings of the fruit, upon which'^the genus had been divided into three, are either 

 too little in accordance with other distinctions, or too variable in certain species, to be avail- 

 able even as sectional. Most of the species are nioua^cious, the female flo\Yers variously 

 Diixed in with the males, and although I have frequently had specimens with the flowers aU 

 of oue or the other kind, I have not been able to ascertain that any species is constantly 

 dioecious, l^he males have uever plumose stigmns, but I always find small obtuse styles and 

 <heir corresponding ovules, which apj)ear often to come to perfection. The females have 

 "suallv smaller petals or none at all, fewer stamens or none or filiform filaments only. As 

 tbe diltereaces between the two are probably the same in nearly all the spc>cics, I have not 

 alluded to them in the specific characters.
