times notched at the top, the foveola at the base small. Torus short. Sta- 

 nuaodia very niuucrous, scarcely exceeding the ovary, clavate, without anthers. 

 Ovary villous, with 2 superposed ovules in each half-cell. Style short, with 

 broad, spreading, fringed^ stigmatic lobes. Pruit (only seen young) small, 

 depressed-globular, with 2 1 -seeded nuts. 



N- Australia. Sandstone rocks, Upper Victoria river, F. Mueller, 



7. G. scabrella, Benl/i. A shrub with the habit of G. orbl/olia, but 



the tomontum rather more sparing. Leaves broadly ovate, but not so rounded 

 as in that species nor quite so rigid, 1 to l\ in. long. Flowers in small ses- 

 sile clusters, apparently dioecious, the males not seen. Pemale fl.: Sepals 

 softly toinentose, 2 to 2^ lines long, tlie buds not striate, as in G. orbifoUa. 

 Petals nearly as long as the sepals, glabrous, with a small foveola at the base, 

 less distinct than in most species. Stamens 1 or sometimes *Z or 3, appa- 

 rently perfect, without staminodia. Ovary oblong, villous, with 2 superposed 

 ovules in each half-cell Style very short, with broad, fringed, spreading, 

 stigmatic lobes.

8. G. orbifolia, F, MitelL Herb, A much-branched shmb, the ycung 

 shoots tomentose. Leaves petiolate, nearly orbicnlar or broadly obovate, very 

 obtuse, irregxdarly serndate, f to 1^ in. diameter, 3- or 5-nerved at the bnse, 

 scabrous-tomentose on both sides. Flowers dioecious, in small sessile clus- 

 ters. Male H. : Sepals 2 to 2\ lines long, tomentose, the buds striate. 

 Petals fully f as long, pubescent outside, the foveola of the base not broader 

 than the lamina. Stamens rather short, inserted on the hirsute torus round the 

 small very rudimentary pistil. Female flower and fruit not seen,

3. TRIUMFETTA, Linn, 



Sepals 5, distinct, usually concave, or with a dorsal point or appendage at 

 the top. Petals 5, thickened and globular, or foveolate at the base, inserted 

 round the base of the torus, rarely wanting. Stamens indefinite, or rarely 

 re<lueed to 5 or 10, free, inserted on the raised torus; anther-cells openuig 

 longitudinally. Ovary 2- to 5-eelled, with 2 collateral ovules in each cell; style 

 filiform, stigma minutely 2- to 5-toothed. Fruit globular or nearly so, echi- 

 nate^ or bristly, indcl)isceut or (in species not Australian) separating mto 

 cocci. ^ Seeds in eacli coccus or cell solitary, or, if 2, separated by vertical 

 dissepiments, pendulous, albuiiiiuous; embryo straight; cotyledons flat, 

 leafy. — Herbs, undershrubs, or shrubs, with the hairs "or tomentum stellate. 

 Leaves serrate, entire, or 3- or 5-lobed. Flowersyellow, in little pedunculate 



or almost sessile cymes or clusters, either leaf-opposed or lateral, rarely strictly 

 axillary. Petals usually narrow and not exceeding the calyx, especially ni 

 the Old World species, 



A considerable genus, widely spread over the tropical regions of both the New and t e 

 Old World. Of the Australian species, one, a maritime plant, extends to several of the ^ou 

 Pacific islands, the others are all endemic.
