Thonner, Franz
Angiosperms -- Africa; Plants -- Africa
2. Ovary with 3 or more ovules. Fruits, at least some of them,
dehiscent, 3-or more-seeded.--Species 9. South and North Africa and
high mountains of Central Africa. Some are used as ornamental plants.
(Including _Cysticapnos_ Adans.) =Corydalis= DC.
Ovary with 1-2 ovules. Fruit indehiscent, 1-2-seeded. Seeds not
appendaged. 3
3. Ovary with 2 ovules. Fruit 2-seeded, compressed, with 3 nerves on
each side. Leaves fleshy.--Species 1. North-west Africa (Algeria).
=Sarcocapnos= DC.
Ovary with 1 ovule. Fruit 1-seeded, compressed but 1-nerved on each
side, or triquetrous, or globular. 4
4. Fruit triquetrous, pendulous. Superior petal helmet-shaped, inferior
spoon-shaped, lateral ones clawed. Stem climbing.--Species 1. South
Africa (Cape Colony). (Plate 52.) =Trigonocapnos= Schlecht.
Fruit globular or compressed, erect.--Species 15. North, South,
and East Africa; also naturalized in West Africa and the Mascarene
Islands. “Fumitory.” (Including _Discocapnos_ Cham. & Schlechtend. and
_Platycapnos_ Bernh.) =Fumaria= L.
5. Stamens 4. Petals 3-cleft. Placentas and styles 2. Juice not
milky.--Species 7. North Africa. Some are used as ornamental plants.
[Subfamily =HYPECOIDEAE=.] =Hypecoum= L.
Stamens numerous. [Subfamily =PAPAVEROIDEAE=.] 6
6. Juice not milky. Flowers solitary. Petals yellow. Placentas 2.
Stigma subsessile, with 4 spreading lobes. Fruit linear, 10-ribbed,
1-celled, 2-valved to the base. Seeds unappendaged.--Species
1. Naturalized in the Canary Islands. Fodder-plant. [Tribe
ESCHSCHOLTZIEAE.] =Hunnemannia= Sweet
Juice milky. Placentas 4 or more, more rarely 2, but then stigmas or
stigma-lobes only 2, or at least partly erect. 7
7. Stigmas (or style-branches) 2, alternating with the 2 placentas and
borne upon a short, but distinct style. Ovary and fruit linear. Seeds
appendaged. Flowers in umbels, yellow. Juice reddish-yellow.--Species
1. North-west Africa. Poisonous and used medicinally. “Celandine.”
[Tribe CHELIDONIEAE.] =Chelidonium= L.
Stigmas (or style-branches) 3 or more, rarely 2, as many as and
opposite to the placentas or more numerous, sessile or nearly so.
[Tribe PAPAVEREAE.] 8
8. Fruit linear, dehiscing to the base. Placentas, stigmas, and
fruit-valves 2-4. Juice yellow. 9
Fruit oblong, ovoid, or globular, dehiscing near the top only or
indehiscent. Placentas, stigmas, and fruit-valves 4-16. 10
9. Petals yellow or reddish-yellow, twisted in the bud. Style ending in
2 erect and 2 spreading lobes. Fruit with a false partition.--Species
2. North Africa and Cape Verde Islands. Used as ornamental or medicinal
plants; the seeds yield oil. =Glaucium= Juss.
Petals violet or red, crumpled in the bud. Style ending in 2-4
connivent lobes. Fruit 1-celled.--Species 4. North Africa. Used as
ornamental plants. =Roemeria= Medik.
