The erect axis or flower stem of Spetaea lachenaliiflora is thick, coloured a dull, deep pinkish purple in picture. It is here angular rather than cylindrical and curving.
The thin pedicels in flower colour blue protrude about horizontally from the stem, the flower tips forming the cylindrical inflorescence. Few flowers are open simultaneously, those below withered, those above waiting to open in nearly oblong bud form (Manning, 2007; Bond and Goldblatt, 1984; iNaturalist).
