224 IRIDACEAE Conservation Key to genera gardens in both tropical and temperate areas. Moraea and the southern African Homeria are poisonous, and cause significant losses in cattle- and sheep-raising areas, especially in southern Africa. Some genera are of importance in traditional medicine, especially Gladiolus. Corms of several species of Lapeirousia and Gladiolus are eaten locally. The corms of several genera were an important source of food for humans in prehistoric time. The most commonly found cultivated members of the family in Ethiopia in general, and Addis Ababa in particular, are Crocosmia × crocosmiiflora (Lemoine) N.E. Br. (syn. Montbretia crocosmiiflora Lemoine) which grows from a corm and has flattened ribbed leaves and spikes of bright orange flowers, and Iris that are probably derivatives of I. germanica L. and I. pallida Lam. The cultivated irises grow from rhizomes and have flattened, greygreen swordshaped leaves and white, blue, purple or even brown flowers. These are included in the key to the genera, but not discussed further in the text. Among the indigenous species there are a number of endemics, mainly in the genus Gladiolus: G. balensis, known only from near Ginir in Bale floristic region; G. negeliensis, near Negelle in Sidamo floristic region; G. mensensis, in a few localities in the highlands of Eritrea; G. calcicola, near Harer in Harerge floristic region; G. longispathaceus, in Sidamo and Gamo Gofa floristic regions; and G. lithicola, near Gara Mulleta in Harerge floristic region. Another endemic species in the family is Lapeirousia abyssinica, known in central and northern Ethiopia and in Eritrea. There is an urgent need to protect habitats which are home for these unique treasures. 1. Stamens opposite and adpressed to style branches; style branches broad, flattened, petal-like with paired terminal crests; leaves bifacial and channelled or terete 2 - Stamens alternate or opposite style branches, but never adpressed to them or style not significantly divided; style filiform and simple or terminating in short lobes or filiform branches; leaves unifacial and equitant, sometimes terete or almost so 3
ARISTEA 225 2. Tepals united below to form a tube Iris - Tepals free 2. Moraea 3. Tepals free to the base; flowers arranged in clusters of 2 or more in biseriate rhipidia, these stalked or sessile; perianth blue, short-lived, open in the morning, collapsing spirally and deliquescing in the early afternoon; rootstock a rhizome 1. Aristea - Tepals united in a perianth tube, and flowers either solitary per branch, or arranged in a spike; perianth variously coloured, lasting at least one full-day and fading slowly, not deliquescing; rootstock a corm 4 4. Flowers solitary; leaves linear (nearly filiform), in section oval to round with 4-longitudinal grooves, and all inserted below ground; perianth tube shorter than tepals 6. Romulea - Flowers 2-many, arranged in a spike or panicle; leaves usually with an expanded plane blade, some at least inserted above ground level; perianth tube shorter or longer than tepals 5 5. Styles dividing at mouth of perianth tube into three long spreading branches. 5. Hesperantha - Styles usually well exserted from tube and either simple or dividing remotely from tube into 3 branches, these sometimes again divided 6 6. Corms campanulate with a flat base; stems somewhat compressed to angled or winged; style branches usually deeply divided 3. Lapeirousia - Corms globose to depressed globose with a rounded base; stems round in section; style branches simple 7 7. Outer and inner bracts coriaceous, green or dry; leaf midrib consisting of more than one pair of veins Crocosmia - Outer and inner bracts membranous to scarious, usually translucent to transparent with veins often dark coloured; leaf midrib consisting of a single pair of veins 8 8. Flowers radially symmetric; perianth pendent and facing the ground; floral bracts scarious and translucent with brown streaking; perianth tube shorter than tepals 4. Dierama - Flowers bilaterally symmetric; perianth usually facing to the side; floral bracts green; perianth tube shorter or longer than tepals 9 9. Style simple 7. Zygotritonia - Style dividing into 3-branches 8. Gladiolus
