Triglochin bulbosa L. subsp. calcicola Mering, Kocke & Kadereit
NT Indigenous Endemic
Morphological description

Plants (5-)10-25 cm high, stiffly erect, with small, fusiform bulbs; bulbs covered by thin soft or thicker stiff, brown fibres, these 61 cm long, fibres sometimes not separate but fused into layers. Leaves as long as infructescence, very narrow, 0.5(-1) mm wide. Inflorescences dense, with (4-)10-30 flowers. Flowers 1.5-2.5 mm long, number of stamens sometimes reduced to three. Pedicels 2-4 mm long, diverging at angles of approximately 45o from the inflorescence axis, slightly curved inwards towards the apex. Infructescences 2-8 cm long. Fruits very narrowly ovoid, 4-7 mm long, rarely longer, mostly < 1 mm wide, very regularly spaced. Mericarps connate; tips short and slightly curved outwards. Carpophore only very thin and short or lacking. From: Kocke, AV; von Mering, S; Mucina, L; Kadereit, JW. 2010.

Diagnostic description

Triglochin bulbosa subsp. calcicola differs from the other subspecies in having dense inflorescences with (4-)10-30 flowers and pedicels diverging at angles of approximately 45° from the inflorescence axis.

Habitat

Triglochin bulbosa subsp. calcicola is a strict endemic of Tertiary calcareous bedrocks such as lime-rich aeolinites (False Bay) and limestones of the Bredasdorp Group (De Hoop and Stillbaai regions) and of the Sandveld Group (Langebaan and Saldanha regions). The sparse populations of this subspecies here occur in shallow loam-filled depressions (filled with fine loam and lime-rich sand) in limestone pavements; these depressions are wet in winter and spring and dry out completely in summer. The vegetation types housing this taxon are De Hoop Limestone Fynbos, Canca Limestone Fynbos, and Saldanha Limestone Strandveld. From: Kocke, AV; von Mering, S; Mucina, L; Kadereit, JW. 2010.

Distribution

This taxon is limited to parts of the West Coast (Langebaan Peninsula), the coast of False Bay (Swartklip and Macassar) and to the South Coast (De Hoop and Stillbaai regions).
