Taxon Profile     (Last Modified On 6/9/2016)
Description: Plants 200–350 mm high, forming rounded cushions. Stems compressed, winged below, angled above, mostly 2- or 3-branched, branches crowded near apex. Leaves linear to sword-shaped, 3–4 mm wide, slightly shorter than stems, firm. Flower clusters 2–4, lateral clusters on short branches and mostly concealed by a subtending leafy bract, each 4–8-flowered; spathes dry and translucent with a narrow green or brown keel, margins closely fringed and rust-brown, 11–14 mm long, bracts entirely translucent smaller than spathes. Flowers blue, on pedicels 2–3 mm long; tepals obovate, 15–20 × 8–9 mm. Filaments ± 5 mm long; anthers ± 3 mm long. Ovary 3-winged, 4–5 mm long; style ± 8 mm long, minutely 3-notched. Capsules oblong in outline, broadly 3-winged, 12–15 mm long. Seeds lamellate, up to 4 per locule, mature seeds not known. Flowering time: December and January.
Country: South Africa
South African Province: Western Cape
Distribution and ecology: known only from higher elevations of the Piketberg in Western Cape, South Africa; on rocky sandstone slopes in fynbos, 500–800 m, flowering well after fire.
Diagnosis: discovered in 1995 flowering profusely after a fire the previous summer, Aristea fimbriata is one of several narrow endemics in the genus. It is distinguished by the flowers with a minutely notched style, relatively long, narrowly winged capsules up to 15 mm long and regularly fringed spathes and floral bracts. The latter are matched in the apparently distantly related A. africana and A. recisa of sect. Aristea but these species have broad, fringed stigmatic lobes. Plants grow in compact low tufts 200–350 mm high. The pollen grains stand out in the Aristea in having a 3-lobed aperture, confined to one face of the grain. Species of sect. Racemosae have pollen grains with a single broadly elliptic aperture and those of sect. Aristea have more complex trisulculate grains with apertures sometimes confluent. Its apparently isolated position in subg. Aristea is supported by molecular studies and A. fimbriata is referred to a separate section, sect. Fimbriatae.
