1. Dipcadi viride (L.) Moench<br />

SCHIZOBASIS DIPCADI 187<br />

The species epithet ‘viride’, meaning green, refers to<br />

the colour <strong>of</strong> the flowers. It was described by Linnaeus<br />

as early as 1762, by him referred to the genus Hyacinthus,<br />

on the basis <strong>of</strong> material from the Cape in South<br />

Africa. Moench transferred it to Dipcadi in 1802. The<br />

appendages on the outer tepals are characteristic for this<br />

heterogeneous species complex.<br />

Plants 20–60 cm long. Leaves, 1–15, very variable in length <strong>and</strong><br />

width, up to 80 cm long <strong>and</strong> 2 cm broad, filiform, linear to broadly<br />

lanceolate, smooth, margin sometimes undulate. Raceme with 5–40<br />

flowers. Pedicels 2–8 mm, up to 11 mm in fruit. Bracts 6–17 mm.<br />

Flowers yellowish green to brownish green. Tepals 8–13 mm, outer<br />

with up to 30 mm long caudate appendages. Capsule 6–14 mm long,<br />

6–15 mm in diameter. Seeds 4–7 mm long.<br />

This species is found in grassl<strong>and</strong>, bush l<strong>and</strong> or woodl<strong>and</strong>,<br />

in s<strong>and</strong>y, stony, sometimes blackish soils, from 450 to<br />

3200 m. It is widespread in <strong>Ethiopia</strong> <strong>and</strong> <strong>Eritrea</strong>. It has<br />

otherwise a wide distribution in tropical <strong>and</strong> southern<br />

Africa. The main flowering period in <strong>Ethiopia</strong> is from<br />

February to June.<br />

The species is heterogeneous <strong>and</strong> more detailed field<br />

studies might justify more taxa on the subspecific – or<br />

even – the specific level. The variation is particularly<br />

pronounced in leaf width <strong>and</strong> tepal tail length, cf. the two<br />

plants presented in the Figure, representing one shorttailed<br />

<strong>and</strong> one long-tailed version. In fact, five species<br />

were described from <strong>Ethiopia</strong>, here all are referred to D.<br />

viride in the wide sense: D. tacazzeanum from Tigray,<br />

D. minimum <strong>and</strong> D. rupicola from Gonder, D. erlangeri<br />

from Bale, <strong>and</strong> the generic wrongly placed Albuca<br />

hyacin thoides from Sidamo. With information from the
