Thonner, Franz
Angiosperms -- Africa; Plants -- Africa
2. Ovary with 1 fertile cell. Flowers regular, glabrous, in
racemes.--Species 1. Natal and Kaffraria. =Barberetta= Harv.
Ovary with 3 fertile cells. Flowers irregular, hairy, in
panicles.--Species 2. Cape Colony. Used as ornamental plants. The roots
contain a red dye-stuff. =Wachendorfia= L.
3. Ovary with 1 ovule in each cell. Flowers hairy, in
panicles.--Species 2. Cape Colony. =Dilatris= Berg
Ovary with numerous ovules in each cell. Flowers glabrous,
solitary.--Species 1. Cape Colony. =Pauridia= Harv.
FAMILY 34. AMARYLLIDACEAE
Flowers hermaphrodite. Perianth corolla-like. Stamens 6, rarely
(_Gethyllis_) more. Anthers introrse. Ovary inferior, rarely
half-inferior or (_Walleria_) almost superior, 3-celled, with slightly
projecting axillary placentas. Ovules inverted. Embryo small, straight,
lateral, enclosed by the fleshy albumen.--Genera 33, species 310.
(Including _HYPOXIDACEAE_.) (Plate 19.)
1. Underground part of the stem a bulb or a corm, rarely a short
root-stock. Leaves all radical. Flowers solitary or in umbels;
inflorescence surrounded by a spathe. [Subfamily =AMARYLLIDOIDEAE=.] 2
Underground part of the stem a root-stock. Flowers in spikes, racemes
or panicles, rarely solitary or in umbels, but without a spathe. 27
2. Perianth furnished with a corona, which sometimes is reduced to a
narrow ring or a crown of hairs. [Tribe NARCISSEAE.] 3
Perianth without a corona. [Tribe AMARYLLIDEAE.] 8
3. Stamens inserted within the corona. Corona cup-or ring-shaped or
consisting of 12 scales. [Subtribe NARCISSINAE.] 4
Stamens inserted on the edge of the cup-or funnel-shaped corona; corona
rarely reduced to a crown of hairs. 6
4. Corona of 12 free scales. Perianth tubular, red. Fruit a
berry.--Species 2. Central Africa (British East Africa and Angola).
=Cryptostephanus= Welw.
Corona cup-or ring-shaped, undivided or lobed. Perianth bell-, funnel-,
or salver-shaped, usually white or yellow. Fruit a capsule. 5
5. Perianth funnel-shaped, with a very short tube, yellow. Corona
little developed, 6-or 12-lobed.--Species 1. North-West Africa.
(_Carregnoa_ Boiss.) =Tapeinanthus= Herb.
Perianth salver-or bell-shaped, with a more or less elongated
tube.--Species 10. North Africa. Used as ornamental plants, in the
preparation of perfumes, and in medicine; some species are poisonous.
(Including _Aurelia_ Gay and _Corbularia_ Haw.) =Narcissus= L.
6. Perianth salver-shaped, with a cylindrical tube and linear segments,
white. Corona funnel-shaped. Ovary with 2 ovules in each cell.--Species
1. West Africa. Used as an ornamental plant. [Subtribe EUCHARIDINAE.]
=Hymenocallis= Salisb.
Perianth funnel-shaped. Ovary with many ovules in each cell. [Subtribe
PANCRATIINAE.] 7
7. Flowers white, regular. Corona large, cup-shaped. Stigma 1.--Species
8. Northern and tropical Africa. Some are used as ornamental plants,
for the preparation of starch, and in medicine. =Pancratium= L.
