1430 CXVII. EUPHOEBIACE^. [Dissiliaiia. 



Cotyledons flat and broad. — Trees or shrubs. Leaves opposite, undivided, entir& 

 or crenulate, penniveined and slightly reticulate. Male flowers very small, on 

 short pedicels, females few together or solitary. Fruits usually solitary. 



The genus is endemic in Australia ; it differs from other Australian Phyllanthece by having: 

 opposite leaves. 



Capsule 8 or 9 lines diameter, the thick corky exooarp deeply furrowed 



on the back of the cocci 1. D. haloghioidet^ 



Capsule 4 or 5 lines diameter, the corky exocarp slightly furrowed on the 

 back of the cocci 2. D. Muelleri. 



Capsule about 4 lines diameter, truncate on the top, the cocci not furrowed 



on the back, with a short conical point or horn on the top 3. D. tricornis. 



1. S. baloghioides (Baloghia-like), F. v. M.: Baill. Adam. vii. 359; 

 Benth. bl. Austr. vi. 90. "Currumgul," Nemng, Schneider. A glabrous tree. 

 Leaves ovate oblong or elliptical, entire, coriaceous, smooth and shining, 2 to Sin. 

 long, on a petiole of about Jin. Female flowers 3-merous [Baillon). Fruiting 

 pedicels 2 to 4 lines long, thick, solitary, apparently terminal. Capsule about an 

 inch diameter, minutely-tomentose, with a thick corky exocarp separating from 

 the hard endocarp, marked outside with narrow furrows between the cocci and a. 

 broad deep furrow along the line of dehiscence on the back of each coccus. 

 Ovules 2 in each cell but only one usually enlarged. Seeds oval, shining. 



Hab.: Moreton Bay, A. Cunningham, also Leiclihardt, and Pine Eiver, Fitzalan. 



Wood hard, close-grained, brown, becoming darker towards the centre of the tree; might 

 be used for any purpose to which the English apple is put, which it somewhat resembles. — 

 Baileifs Gat. Ql. Woods, No. 366. 



Wood used for nullahs, spears and paddymelon sticks, Schneider. 



2. S. Muelleri (after Baron Mueller), Baill. Adans. vii. 859, t. 1 ; Benth. 

 Fi. Austr. \i. 91. A glabrous shrub or tree. Leaves broadly ovate, sometimes 

 almost cordate, obtuse, irregularly crenulate, 1 to Sin. long and broad, on a 

 petiole of about -J-in. Female flowers in short cymes apparently terminal, the- 

 fruiting pedicels J to -Jin. long. Calyx of 3 or 4 broad segments, imbricate in 

 the bud. Petals rather longer than the calyx. Disk short, crenulate, close- 

 round the base of the ovary. Capsule globular, 4 to 5 lines diameter, slightly 

 tridymous and furrowed on the backs of the cocci, the thick corky exocarp. 

 separating from the endocarp as in D. haloghioides. 



Hab.: Eockhampton, Thozet, Dallachy. 



S. S. tricornis (3-horned), Benth. Fl. Austr. vi. 91. A shrub, with th& 

 young branches pubescent, the adult foliage nearly glabrous. Leaves ovate 

 elliptical or almost lanceolate, very obtuse, crenulate, rounded or contracted at 

 the base, coriaceous, shining and veined above, pale with the midrib pubescent 

 underneath, 1 to l^in. long, on a petiole of i^in. or less. Flowers in sessile 

 clusters in the upper axils or appearing terminal from the non-development of th& 

 terminal bud, the males numerous, on slender pedicels of 1 to 3 lines, the females 

 1 or 2 in each axil on shorter thick pedicels. Bracts small, villous. Male 

 perianth glabrous, of 4 rarely 6 broad segments, ^ to f line long, somewhat petal- 

 like, especially the inner ones which are rather longer. Stamens 4, rarely 6 or 

 more, on a hairy receptacle, longer than the perianth. Female perianth of S 

 rather acute or mucronulate glabrous segments, and 3 smaller inner lanceolate or- 

 linear ones alternating with them. Disk very hairy, but not prominent. Ovary 

 very short, tapering into 3 distinct styles much thickened at the base as in 

 Fseudanthus. Capsules on pedicels of 2 to 4 lines, pubescent, about 4 lines 

 diamej;er, tridymous, flat-topped, hard, with a small conical point or horn on the- 

 top of each coccus but no furrow on the back. Seeds only ripening one ^of ,the- 

 two ovules of each cell, ovoid, without any carunculus.
