This species is, so far as we know, confined to the dry western portions
of the Cape Province, S.W. Protectorate, Transvaal, and Orange Free
State. Burchell found the plant both in Griqualand West and in
Bechuanaland, and Burke on his journey up to the Transvaal found it near
the Sand River in the Orange Free State. In habit the species very much
resembles a dwarf _Brunsvigia_, but is distinguished from this genus by
the obtusely angled ovary. The short stout peduncle is also found in two
other species of _Nerine_.
A coloured plant of _N. lucida_ was published in 1820 (_Botanical
Register_, Plate 497), drawn from a plant which flowered in the garden
of Prince Leopold of Saxe-Cobourg.
The specimens from which the accompanying Plate was prepared were
collected at Vryburg by Mr. A. O. D. Mogg, and flowered at the Division
of Botany, Pretoria, in 1924.
DESCRIPTION:--_Bulb_ globose, 4 cm. in diameter, produced into a neck
about 4 cm. long. _Leaves_ 6, contemporary with the flowers, about 18
cm. long, about 12 mm. broad, strap-shaped, obtuse, bright green.
_Peduncle_ lateral, about 12 cm. long, compressed. _Inflorescence_ an
umbel of 20 flowers. _Pedicels_ up to 7 cm. long, shortly hairy.
_Spathe-valves_ ovate-lanceolate, membranous, shorter than the pedicels.
_Perianth-segments_ 15 mm. long, 5 mm. broad, lanceolate-linear, obtuse.
_Stamens_ declinate, almost as long as the perianth segments. _Ovary_
obtusely trigonous; style declinate, as long as the stamens. (National
Herb., Pretoria, No. 2835.)

upper portion of perianth lobe, showing apex; Fig. 3, cross-section

This charming little _Eulophia_ is found in the summer months round
Pretoria growing in the grass veld, and is fairly abundant. Like many
other plants found in the neighbourhood of the Magaliesberg, it was
collected by the travellers Burke and Zeyher. It ranges from the Maclear
Division, through the Orange Free State, to Natal and the Transvaal.
_E. leontoglossa_ belongs to the same small group (four species) in the
genus as _E. Zeyheri_ (figured on Plate 119), which is characterised by
the flowers being arranged in congested racemes or short heads. Like _E.
Zeyheri_ also, the tubers are arranged in a linear series and resemble
large oval beads.
Our figure was made from specimens collected by Dr. I. B. Pole Evans,
C.M.G., at Irene, near Pretoria.
