7. Petals or petaloid staminodes numerous, united at the base. Stamens
numerous. Flowers conspicuous. Leaves exstipulate, fleshy.--Species 1
=Orygia= Forsk.
Petals none, but the stamens sometimes intermixed with staminodes.
Leaves stipulate. 8
8. Styles linear or slightly club-shaped. Stipules membranous, entire. 9
Styles obovate or wedge-shaped. Stipules fringed or sheath-like. 10
9. Ovules with a long funicle. Seeds crowned by an appendage of the
funicle. Pericarp firm.--Species 3. Used in medicine. =Glinus= L.
Ovules with a short funicle. Seeds without an appendage of the
funicle. Pericarp thin. Stamens 3-10. Glabrous herbs with narrow
leaves.--Species 10. Tropical and South Africa. Some species are used
in medicine. =Mollugo= L.
10. Disc cup-shaped, lobed or divided. Stamens 3-5. Stipules
fringed.--Species 17. South Africa, Madagascar, St. Helena.
=Pharnaceum= L.
Disc none. Stipules sheath-like. Leaves thread-shaped.--Species 4.
South Africa. =Hyperstelis= E. Mey.
11. (1.) Ovary superior. Petals none. 12
Ovary inferior. [Tribe MESEMBRIANTHEMEAE.] 18
12. Fruit transversely dehiscent, circumscissile. Leaves opposite.
[Tribe SESUVIEAE.] 13
Fruit longitudinally dehiscent, loculicidal or septicidal. [Tribe
AIZOEAE.] 14
13. Ovary 1-2-celled. Ovules solitary or few, basal or subbasal.
Pericarp thick in the upper part. Seed-coat wrinkled.--Species 10. Some
of them are used as vegetables or in medicine. (Plate 43.) =Trianthema=
L.
Ovary 3-5-rarely 2-celled. Ovules numerous, axile. Pericarp thin.
Seed-coat smooth. Flowers red.--Species 6. Tropical and South Africa.
Some of them have edible seeds, or serve as vegetables. (Including
_Diplochonium_ Fenzl and _Halimus_ Rumph.) =Sesuvium= L.
14. Stamens 4-5. Ovary-cells and styles 3. 15
Stamens 8 or more. 16
15. Ovary-cells 1-ovuled. Filaments long. Fruit roundish. Shrubs
with silky hairs. Leaves all cauline, opposite or alternate,
imbricate, triangular-ovate, without stipules. Flowers axillary,
yellowish.--Species 1. South Africa (Cape Colony). =Plinthus= Fenzl
Ovary-cells several-ovuled. Filaments short. Fruit linear-oblong.
Glabrous herbs. Radical leaves lanceolate to ovate, with fringed
stipules; cauline leaves whorled, filiform. Flowers in cymes,
whitish-green.--Species 2. South Africa. =Coelanthum= E. Mey.
16. Stamens numerous. Ovary 4-5-celled. Styles 4-5. Ovules 2 or more in
each cell. Flowers yellow.--Species 12. Some of them have edible seeds.
=Aizoon= L.
Stamens 8-10, rarely more, but then ovary 2-celled and styles 2. Ovules
1 or 2 in each cell. 17
17. Stamens 10 or more. Ovary 2-celled. Styles 2. Ovules basal. Stem
glabrous.--Species 4. South Africa. =Acrosanthes= Eckl. & Zeyh.
Stamens 8, rarely 10, but then ovary 3-5-celled, styles 3-5, and stem
