Trachy<strong>and</strong>ra saltii<br />

Description<br />

JODRELLIA TRACHYANDRA 125<br />

The plants grow on rocky slopes with mixed woodl<strong>and</strong><br />

<strong>of</strong> Acacia, Commiphora, <strong>and</strong> Delonix, around 900 m.<br />

It is a near­endemic species, only known from the Bale<br />

floristic region <strong>and</strong> the adjacent parts <strong>of</strong> Somalia <strong>and</strong><br />

Northern Kenya. The species has only been collected<br />

in the fruiting stage from April to May, thus it probably<br />

flowers sometimes in March to April.<br />

4. TRACHYANDRA Kunth<br />

The genus includes grass­like pubescent plants, growing<br />

from a vertical rhizome with fleshy roots. There are<br />

several inflorescences per plant. The flowers are open,<br />

star­like, with subequal, one­nerved, white tepals. The<br />

stamens are subequal, the filaments scabrid, but never<br />

hairy. The capsules are subglobose, with few to many<br />

seeds.<br />

The genus is predominantly South African, with about<br />

50 species, <strong>of</strong> which most are endemic in the winter<br />

rainfall areas in south­western Cape. Only one species<br />

reaches north <strong>of</strong> the equator <strong>and</strong> to <strong>Ethiopia</strong> <strong>and</strong> Yemen.<br />

Trachy<strong>and</strong>ra saltii (Baker) Oberm.<br />

The species epithet refers to the collector, Salt, who<br />

collected the plant somewhere in <strong>Ethiopia</strong>; precise<br />

locality not known. It was described by Baker as a species<br />

in the genus Anthericum in 1876, <strong>and</strong> transferred to<br />

Trachy<strong>and</strong>ra by Obermeyer in 1962. This species looks<br />

superficially like an Anthe ricum, but it has the typical Aspho<br />

delaceae traits in chemistry <strong>and</strong> seeds.<br />

Short vertical rhizome with many fleshy roots <strong>and</strong> sometimes<br />

with fibres from previous years leaves. Leaves, up to 35 × 0.4<br />

cm, slightly olive-green, filiform to linear, gradually exp<strong>and</strong>ing to<br />

broad sheathing membranaceous base, more or less pubescent with<br />

long white hairs. Scapes (including the inflorescence) pubescent,<br />

13–45 cm long, curved near the base. Raceme lax; bracts narrow,<br />

cuspidate, up to 10 mm long; pedicels 8–15(–20) mm long, patent<br />

or recurved, elongating somewhat in fruit. Tepals white, c. 10<br />

mm long, with a brownish dorsal median b<strong>and</strong>; stamens slightly<br />

shorter than the tepals, anthers light yellow, ca. 1mm long. Capsule<br />

subglobose, c. 5 mm in diameter, constricted at the base, with dull,<br />

greyish, angled seeds.
