Taxon Profile     (Last Modified On 7/28/2016)
Description : Plants 1 200–2 000 mm high. Corm depressed-globose, 30–50 mm diam.; tunics coarsely netted. Stem erect or inclined below, usually with several short, ascending branches. Leaves 5 to 8, mostly basal, upper basal leaf sheathing stem below or entirely, 1/3–2/3 as long as spike, lanceolate to linear, 20–40 mm wide, bright apple-green, midrib lightly and margins lightly to moderately thickened; bract-like cauline leaves 2 or more, overlapping. Spike up to 20-flowered; bracts green below and dry and brownish above or entirely, often ± sticky, 10–18 mm long, inner ± as long or 2–3 mm shorter, acute or forked apically for 1–2 mm. Flowers zygomorphic, pale to deep pink or pale purple, darker in midline of lower 3 or all tepals and with white streak at base, rarely entirely white, faintly scented; perianth tube funnel-shaped, lower part 12–15(–20) long, emerging 3–8 mm from bracts, upper part flaring, ± horizontal to slightly pendulous, 8–20 mm long, 7–10 mm diam. at mouth; tepals spreading, oblanceolate to obovate, (26–)30–36 × 13–18 mm. Filaments unilateral, either arcuate-horizontal and somewhat spreading or decumbent, 13–18(–25) mm long; anthers 10–13mm long, purple (yellowish when flowers white). Style arching above or below stamens, dividing at or below anther apices, branches up to 7 mm long. Capsules ovoid to obovoid-truncate, 20–25(–30) × 7–10 mm. Seeds unequally 2-winged, 8–12 mm long, distal wing 2–3 mm long, proximal smaller or vestigial. Flowering time: October to early December (January).
Country : South Africa
South African Province : Western Cape
Distribution and ecology : endemic to the extreme southwestern part of Western Cape, from Tulbagh to the Cape Peninsula eastward to Bredasdorp, on rocky, usually well-drained sandstone or granite slopes.
Diagnosis : a robust species with bright apple-green leaves and well-branched stems more than 1 000 mm tall, with funnel-shaped, pink flowers, the perianth tube flared in the upper ± half and 20–40 mm long. The filaments vary in orientation from  arcuate-horizontal to decumbent. Watsonia rogersii is a shorter species, up to 500 mm high, with narrower, dull green leaves 5–10 mm wide with heavily thickened margins, and often slightly smaller flowers with tepals 22–30(–35) mm long. The two species are sympatric along the lower slopes of the Hottentots Holland and Kogelberg ranges and may hybridise there. The orientation of the stamens in Watsonia borbonica varies between the northern and southern populations and this variation, combined with small differences in the length of the perianth tube, forms the basis for the recognition of two subspecies.
General Notes : hybrids between subsp. borbonica and W. zeyheri have been reported from Betty's Bay.
