P. sekhukhuniensis most closely resembles P. leptophylla var. leptophylla, however, the leaf size of the former is 7-15 x 1-2.5 mm, whereas the leaves of the latter one are 14-22 x 1.5-3 mm Flowers of P. sekhukhuniensis differ from P. leptophylla var. leptophylla in the crest of the former being purple and the alae pink with darker pink veins, whereas the crest is white, pink or purple in the latter, with the alae whitish to yellowish with green veins. Seeds of P. sekhukhuniensis differ from P. leptophylla var. leptophylla in the colour of the testa, dark brown-black versus reddish-brown, the bare patch on the testa between the caruncle and the indumentum (the size, 0.3 x 0.6 mm versus 1.2 x 1.5 mm), and the caruncular appendages, poorly developed (0.2 versus 0.8 mm long).
