40. Perianth funnel-shaped, whitish, with oblong-ovate segments. Style
short; stigma 3-lobed.--Species 1. North Africa (Cyrenaica). =Lloydia=
Salisb.
Perianth wheel-shaped, usually yellow and with lanceolate segments.
(See 6.) =Gagea= Salisb.
41. (1.) Branches leaf-like, but often awl-shaped. Leaves scale-like.
Flowers axillary, solitary or in pairs, more rarely in fascicles,
umbels, or racemes. Fruit a berry. [Tribe ASPARAGEAE.] 42
Branches not leaf-like; stem usually simple. Leaves well developed. 44
42. Flowers inserted at the base of the usually linear leaf-like
branches. Perianth-segments free or slightly united at the base.
Stamens 6, with free filaments.--Species 80. Some of them are used
as vegetables, medicinal-, ornamental-, or hedge-plants. (Including
_Myrsiphyllum_ Willd.) =Asparagus= L.
Flowers inserted on the surface or margin of the lanceolate or broader
leaf-like branches. Stamens with united filaments. 43
43. Flowers hermaphrodite. Perianth-segments united high up. Anthers
6. Ovary 3-celled. Style distinctly developed; stigmas 3.--Species 1.
Canary Islands, Madeira, and Azores. =Semele= Kunth
Flowers dioecious. Perianth-segments free. Anthers 3. Ovary 1-celled.
Style very short; stigma lobed.--Species 2. North Africa. Used as
ornamental and medicinal plants. =Ruscus= L.
44. Flowers solitary, axillary. Anthers turned outwards. Fruit
capsular. [Tribe UVULARIEAE.] 45
Flowers solitary but terminal or collected into various inflorescences.
Anthers turned inwards. 47
45. Perianth-segments free, spreading or reflexed. Style bent downwards
at the base.--Species 5. Tropical and South Africa. Poisonous and
used as medicinal and ornamental plants; some of them yield starch.
=Gloriosa= L.
Perianth-segments united below or connivent. Style not bent downwards.
46
46. Perianth-segments free or almost so, with a nectar-bearing cavity
at their base.--Species 6. Tropical and South Africa. Some are used as
ornamental plants. =Littonia= Hook. fil.
Perianth-segments united almost to the top into a pitcher-shaped tube,
with a short spur at the base.--Species 1. South-East Africa. Used as
an ornamental plant. =Sandersonia= Hook. fil.
47. Flowers solitary, in 2-3-flowered heads, in axillary cymes, or in
umbels, the latter sometimes arranged in racemes. 48
Flowers in spikes, racemes, or panicles, which are sometimes contracted
into many-flowered heads or consist of fascicles or cymes. 52
48. Stem herbaceous. Leaves radical, linear, parallel-veined.
Inflorescence terminal. Fruit a capsule. 49
Stem woody at least at the base, usually climbing. Leaves cauline,
oblong or broader, net-veined. Inflorescence axillary. Fruit a berry. 51
49. Flowers solitary or in groups of 2-3, surrounded by an involucre of
5-7 bracts, sessile. Perianth-segments free. Ovary-cells with a single
ovule.--Species 1. North Africa. [Tribe APHYLLANTHEAE.] =Aphyllanthes=
L.
