Holland Mountains, fl. Nov. 1923, T. P. Stokoe (Bolus Herbarium, No. 
17463!). Exact locality uncertain: obtained from Kuil’s River by 
M. R. Levyns (Bolus Herbarium, No. 17462 !). 
Stem erect robust, up to 45 cm. high, entirely covered by the 
leaves; leaves 8 — 9, erect, oblong or broadly ovate-oblong or linear, the 
lower sheathing, sheath 2 — 3 cm. long, the upper ones stem-clasping, 
narrowed towards the apex, margins undulate, up to 16 cm. long, 2 — 6 cm. 
wide; spike rather laxly 17-fl., flowers ascending; bracts very large, 
equalling the flowers or the lower ones well over-topping them, herbaceous, 
loosely ensheathing the ovary, somewhat rhomboidal, narrowed upwards, 
acuminate, 6 — 2 cm. long; odd sepal hooded, mouth orbicular, the spur 
spreading, then decurved, often incurved at the truncate apex, laterally 
somewhat compressed and channelled, 5 mm. long; lateral sepals oblong 
obtuse, 1-4 cm. long; petals somewhat falcate, dilated upwards, obliquely 
somewhat truncate at the apex or rather acute, 6 mm. long, the anterior 
lobe oblong, rounded at the apex, 3 — 4 mm. long; lip ascending-spreading 
oblong-linear, rounded at the apex, rough with minute prominent 
papillae, 1-1 cm. long, 4 mm. wide; rostellum almost square, with the 
lobes contiguous ; anther almost horizontal or slightly sloping downwards ; 
ovary usually 2 — 2-5 cm. long, stigma nearly orbicular. 
Described from the dried specimens and the drawing made from a 
complete living specimen collected by Mr Stokoe and an almost complete 
one given to Mrs Levyns as being from Kuil’s River, in the Stellenbosch 
Division. The latter was more robust and slightly larger in all its parts. 
The species is closely allied to D. cornuta, Sw. and D. macrantha, Sw., and
