6 SYNOPSIS OF THE ORDERS^ 



5. Berberidaceae (p. 52). Sepals and petals imbricate, each in two rows of 



three (rarely in twos or fours). Stamens opposite the petals. Pistil 

 solitary, becoming a berry or pod. Shrubs or low herbs. 



6. Nymphaeaceae, in part (p. 54). Sepals and petals each 3, or many in 



several rows. Pistils becoming coriaceous and indehiscent. Aquatics : 

 floating leaves peltate. 



# 2. Carpels (2 or more) united into a compound ovary with parietal, often 

 nerve-like placentae (or the seeds covering the inner surface in Nymphae- 

 aceae, and the placentae axile in Sarraceniaceae). Herts (some Cistacese 

 somewhat shrubby). 



- Fruit 5 - many-celled ; calyx or whole perianth persistent ; embryo small, 

 at the base of fleshy albumen. 



6. Nymphaeaceae proper (p. 54). Sepals 2-6. Petals and stamens nu- 



merous, on a thick hypogynous receptacle or inserted upon the ovary. 

 Capsule 8 - 30-celled. Aquatics, with peltate or cordate leaves. 



7. Sarraceniaceae (p. 57). Sepals and petals 5. Capsule 5-celled. Marsh 



plants, with pitcher-shaped leaves. 

 *- 4- Fruit 1 -celled, or spuriously 2 - more-celled by partitions connecting the 



placentae. 

 -* Embryo minute at the base of fleshy albumen ; perianth deciduous ; sepals 2. 



8. Papaveraceae (p. 57.) Flowers regular. Sepals fugacious. Petals 4 - 



12. Stamens and seeds numerous. Capsule 2 - several-valved. Juice 

 milky or colored. 



9. Fumariaceae (p. 59.) Flowers irregular. Petals 4, in dissimilar pairs. 



Stamens 6, diadelphous. Fruit 2-valved (indehiscent and 1 -seeded in 

 Fumaria). Juice watery ; leaves dissected. 



*+ ++ Albumen none ; embryo curved or folded ; perianth deciduous (sepals 

 persistent in Resedaceae). 



lo Cruciferae (p. 61). Sepals and petals 4. Stamens mostly 6, tetradyna- 

 mous (two inserted lower and shorter). Pod 2-celled by a transverse par- 

 tition, 2-valved, or sometimes indehiscent or transversely jointed. Bracts 

 and stipules none. 



1 1 . Capparidaceae (p. 74). Sepals and petals 4. Stamens 6 or more, nearly 

 equal. Pod 1 -celled, 2-valved. Embryo coiled. Leaves often palmately 

 divided ; bracts and stipules often present. 



12. Resedaceae (p. 75). Sepals and petals 4-7, irregular. Stamens indefi- 



nite on an hypogynous disk, not covered in the bud. Pod 1 -celled, 3-6- 

 lobed, opening at the top. 



^ ++ -w. Embryo rather large in fleshy albumen ; placentae on the middle of 

 the valves ; calyx persistent. 



13. Cistaceae (p. 76). Flowers regular; sepals and petals 5, the two outer 

 sepals minute. Stamens indefinite. Pod 1-celled, 3-5-valved. Ovules 

 orthotropous. Embryo curved. Leaves entire, the lower often opposite. 



14. Violaceae (p. 78). Flowers irregular; sepals and petals 5. Stamens 5 f 

 with connivent introrse anthers. Style clavate. Pod 1-celled, 3-valved.
