Disa bolusiana

Disa bolusiana, commonly known as the Harry Bolus orchid, sometimes as the ridge disa and previously scientifically as Monadenia bolusiana, is a tuberous perennial reaching heights from 15 cm to 30 cm.

Two to five leaves are grown at ground level and a few more up the stem. The lowest, biggest ones are usually a little longer than 5 cm. The nearly erect leaves are narrowly oblong to ovate, broadening at the base where they clasp the stem and taper to acute tips.

The slender, erect flowering stems bear two to twenty five flowers in dense spikes. Flowering is most abundant after fire

The species distribution is in the Western Cape, from the Cape Peninsula to around Wellington and the Langeberg Mountains to Riversdale.

The habitat is gravelly upper fynbos slopes and ridges. The habitat population is deemed of least concern early in the twenty first century (Marais, et al, 2017; Liltved and Johnson, 2012; Bond and Goldblatt, 1984; iNaturalist; http://redlist.sanbi.org).
