8. • Habit and leaf form. Small shrubs, or herbs.
• ‘Normal’ plants, or plants of very peculiar
vegetative form;. Leaves well developed
(usually), or much reduced.
• Plants succulent/non succulent.

9. • The herbs annual, or perennial; with a basal
aggregation of leaves, or without conspicuous
aggregations of leaves.
• Leaves minute to medium-sized; alternate, or
opposite (or in false whorls); shortly petiolate to
sessile;
• Lamina entire; one-veined, or pinnately veined,
or palmately veined. Leaves stipulate, or
exstipulate.

10. • Plants hermaphrodite (usually), or
monoecious (rarely), or dioecious (rarely).
• Floral features
• Flowers solitary, or aggregated in
‘inflorescences’; when aggregated, in cymes,
or in heads.. Inflorescences cymes and heads.
• Flowers small, or medium-sized; regular; not
resupinate; cyclic; pentacyclic to polycyclic.
Hypogynous disk present, or absent.

11. • Perianth sepaline, or with distinct calyx and
corolla (1–)4–5(–20), or 20–120 (if the
staminodes are interpreted as petals).

12. • Calyx (1–)4–5(–8); 1 whorled; gamosepalous
(nearly always), or polysepalous regular, or
unequal but not bilabiate fleshy; persistent;
imbricate, or valvate (rarely).
• Corolla of 5–120 (of staminodal origin); 1–6
whorled.

13. • Androecium (3–)4–5, or 8–10, or 15–200 (i.e.
to ‘many’, by branching). Androecial members
commonly branched or unbranched; when
branched/many, maturing centrifugally;

14. • when coherent 3–9 adelphous or 1 adelphous
(the filaments basally connate into bundles, or
forming a short monadelphous sheath);
• 1–16 whorled (i.e to ‘many whorls’).

15. • Androecium including staminodes (nearly
always), or exclusively of fertile stamens (i.e.
occasionally no staminodal ‘petals’). free of
one another, or coherent;

16. • Staminodes when present, 3–120 (usually
numerous); external to the fertile stamens;
petaloid. Stamens (1–)5, or 6–120 (i.e. to
‘many’);
• reduced in number relative to the adjacent
perianth (rarely), or isomerous with the
perianth, or diplostemonous to
polystemonous.

17. • Gynoecium (1–)2–5(–20) carpelled.
• Gynoecium syncarpous (rarely
pseudomonomerous); superior to inferior.
Ovary (1–)2–5(–20) locular.
• Gynoecium non-stylate to stylate. Styles 1–20
(or absent); apical, or apical to lateral
(excentric). Stigmas (1–)2–5(–20);

18. • Placentation when unilocular (i.e.,
rarely) parietal; when plurilocular, axile
(typically), or basal (rarely), or axile to apical
(e.g. Galenia), or parietal
• (Mesembryanthemum sensu lato).
Ovules (1–)50 per locule;

19. • Fruit fleshy (rarely), or non-fleshy; dehiscent,
or indehiscent; a capsule, or a berry. Capsules
loculicidal, or valvular, or septicidal, or
circumscissile. Seeds non-endospermic.

20. • Species 1100. Genera 126;
• Common species.
Trianthema, Mollugo,Giesekia
• Economic uses, etc. Edible fruit
from Mesembryanthemum edule (Hottentot
fig).
