8. Violacese. Pets 5, the lower one prolonged in a spur. 
Stas 5. Caps. 1-celled, S-valved.—Ls stipulate. 
22. Balsamineae. Cor. and stas as above. Caps. 5-celled, 
opening elastically by 5 valves.—Anthers united, covering the 
ovary like a veil. Ls. exstipulate. 
| | Stas more or less united. 
O Cor. reg. (in Erodium the pets, rather unequal). 
Stas monadelph. at the base. Cl. 16. 
40. Tamariscineae. Stas 10. Style 1. Caps. Seed with a hairy 
crest.—Lig. pis. 
21. Geraniaceae. Stas 10. Styles 5. Schizocarp.: 5 1-seeded 
carpels detaching themselves from the central beak-shaped axis. 
15. Lineae. Stas 5—4, often accompanied by rudimentary 
filaments. Styles 5—4. Caps. 5—4-celled. The cells div. into 
2,l-seeded secondary cells by a false partition, whence the fr. 
appears to be 10—8-celled. 
23. Oxalideae. Stas 10. Styles 5. Caps. 5-celled, the cells 
undivided.—Ls ternate, like clover. 
0 Cor. irreg. Stas united in 2 bundles (Cl. 17).—Style 1. Stipules 0. 
5. Fumariaceae. Cor. spurred. S e p s 2, decid., often very small. 
Stas 6. Achene l-seeded, indehisc. (Fumaria) or siliqua 2-valved 
(Corydalis).—Ls ternate, biternate or pinnatisect. 
11. Polygalaceae. Cor. without spur. Seps 5, the 2 lateral 
ones (wings) larger, coloured. Stas 8. Caps. 2-celled.—Ls 
undiv. and entire. 
Perigynous polypetalse. *) 
Insertion of cor. (and stas) peri- or epigynous.—Ovary sup. or inf. 
f Ovary free (Comp. Saxifragaceae and Rosa Cl. 12, 23). 
§ Ovaries 2 or more. FI. reg. Stas gen. numerous ( comp. 
Sibbaldia and Crassula). 
46. Crassulaceae. Pets 3—20. An equal number of many- 
seeded follicles with hypog. scales at the base. Stas as many 
or gen. twice as many as pets.—Fleshy-succulent pis 
with undiv. exstip. ls. 
30. Spiraeaceae. Pets gen. 5.—Fr. composed of 2 to 10 
2—6-seeded follicles. 
31. Rosaceae. Pets gen. 5. Achenes numerous, l-seeded 
(rarely in Agrimonia 2—l-seeded). Ls often compound, stipu¬ 
late. The Amggdalacece are distinguishable by the drupe, the 
Pomacece by the ovary and cal.-tube being joined, the San- 
guisorbece by the absence of pets. 
*) Of the perigynous monopetalse- Oxycoccos, Phyteuma and Ja- 
sione are almost polypetalous.
