or in the Australian species 4-celled, with 2 or more ovules in each cell ; styles 
as many as cells, filiform, stiginatic along the inner side. Capsule surrounded by 
the persistent calyx, depressed, opening loculicidally in as many valves as cells, or 
in the Australian species the valves split septicidally. — Herbs or undershrubs. 
Leaves alternate or rarely opposite, without stipules. Flowers solitary or divari- 
cately cymose. 
The genus is chiefly African, and especially S. African, but extending to N. Africa and S. 
Europe. 
Plant scurfy-tomentose. Leaves narrow-linear 1. A. quadrifidum. 
Plant glabrescent. Leaves ovate-lanceolate 2. A. zygophylloides. 
1. A. quadrifidum (capsule four- valved), F. /•. M. Frar/m. ii. 148; Benth. 
FI. Arntr. iii. 827. A rigid shrub, probably small, with divaricate opposite or 
dichotomous branches, covered as well as the leaves with a dense but 
close almost scurfy tomentum. Leaves opposite, narrow-linear, obtuse, 
rather thick and soft, not above iin. long in the specimens. Flotvers 
shortly pedicellate, terminal or in the forks. Calyx tomentose; tube short, 
broadly turbinate, the ribs not prominent; lobes -J, valvate, ovate-acuminate, 
about 8 lines long. Stamens numerous, densely crowded opposite the 
sinus of the calyx, more distant opposite the lobes ; filaments slender, more or 
less covered like the ovary with transparent vesicular cells, about as long as the 
calyx-lobes. Ovary truncate on the top, d angled, 4-celled, with 4 styles stigmatic 
along their inner side. Ovules numerous. Capsule almost free, obpyramidal- 
truncate, septicidally dehiscent in 4 truncate valves, loculicidally divided almost 
to the base. — Sesuriwn quadrifidum, F. v. M. Rep. Babb. Exped. 9. 
Hab.: Southern border towards Cooper’s Creek, .7. Ivory. 
2. A. zygophylloides (Zygophyllum-like), /■’. r. M. Frar/m. vii. 129. The 
young branches densely clothed with papulose scales. Leaves lanceolate-ovate, 
attaining a width of 5 lines, opposite, glabrescent. Flowers solitary, calyx deeply 
4-fid, lobes lanceolate-oblong, yellow on the inside, not at all acuminate, almost 
glabrous. Stamens very numerous ; styles 4 ; ovary 4-celled ; ovules numerous. 
Hab.: Queensland (without locality), F. v. Mueller. 
This plant, as seen from the fragmentary specimens examined, seems more a distinct species 
than a form of A. quadrifidum, from which it is mostly distinguished by being more glabrous, 
and by the form of the leaves and lobes of the calyx. — F. r. M. l.c. 
4. GUNNIA, F. v. M. 
Calyx free, deeply divided into 4 lobes, valvate in the bud. Petals none. 
Stamens 4, inserted on the calyx-tube and alternating with its lobes. Ovary 
superior, enclosed in the calyx, 4-celled, with several ovules in each cell ; styles 
4, filiform, stigmatic along the inner side. Capsule enclosed in the persistent 
calyx, opening loculicidally, each valve splitting septicidally. Seeds numerous, 
small; testa thin and smooth ; embryo curved round a mealy albumen. — Small 
diffuse annuals. Leaves opposite. Flowers terminal or in the forks, nearly 
sessile. 
The genus is limited to Australia. 
1. Gr. septifraga (mode of dehiscence), F. v. 37. Hep. Babb. Exped. 9 ; 
Benth. FI. Arntr. iii. 327. The specimens described from one small fragment. 
Branches slender, the single pair of floral leaves preserved linear. Flowers nearly 
sessile in the forks or terminal. Calyx-lobes acute, about line long when in 
flower, 2 lines long when in fruit. 
Hab.: Southern border inland.
