General Description

Plants 1-1.5 m. high. Corm depressed-globose, 5-7 mm. in diameter, the tunics reddish and irregularly broken. Foliage leaves several, mostly basal or inserted in the lower part of the stem, reaching to ± the base of the spike, lanceolate, sometimes narrowly so, (1.3-)2-3.5 cm. wide, the margins, midrib and usually at least one other pair of veins thickened and hyaline, the surface densely and minutely papillose to shortly pubescent. Stem unbranched. spike erect, 6-10-flowered, the nodes 3-7 cm. apart; bracts 4-6(-7) cm. long, green, the inner 1-2 cm. shorter than the outer. Flowers pale yellow with greenish highlights; perianth-tube 3-4 cm. long, curving outward above, gradually expanding toward the apex; tepals unequal, the upper 3 ± 4 cm. long, the dorsal hooded over the stamens, ± 2 cm. wide, the upper laterals directed forward and curving outward only apically, the lower 3 tepals 1/2-1/3 as long as the upper, curving downward from the base. Filaments 2.5-3 cm. long, exserted at least 1.5 cm.; anthers 1.4-1.7 cm. long. Style arching over the stamens, dividing near the anther-apices, the branches ± 5 mm. long. Capsules unknown.

NOTE. Closely allied to {i}G. dalenii{/i} but with a larger flower, a pale lemon yellow and greenish perianth, and distinctive leaves the entire surface covered with a dense, minute papillose indumentum, and often the secondary veins thickened and hyaline.

Plants 1–1.5 m high. Corms 5–7 mm in diameter, depressed-globose; tunics reddish, irregularly broken. Foliage leaves several, mostly basal or inserted in the lower part of the stem, reaching to about the base of the spike, (13)20–35 mm wide, lanceolate, sometimes narrowly so, the margins, midrib and usually at least one other pair of veins thickened and hyaline, the surface densely and minutely papillose to short-pubescent. Stem unbranched. Spike 6–10-flowered, the nodes 3–7 cm apart; bracts green, 4–6(7) cm long, the inner 1–2 cm shorter than the outer. Flowers pale-yellow with greenish highlights; perianth tube 30–40 mm long, curving outward above, gradually expanding toward the apex; tepals unequal, the upper 3 tepals c. 4 cm long, the uppermost c. 2 cm wide and hooded over the stamens, the upper lateral tepals directed forward and curving outward only near the apex, the lower 3 tepals half to one-third as long as the upper, curving downward from the base. Filaments 25–30 mm long, exserted at least 15 mm; anthers 14–17 mm long. Style arching over the stamens, dividing near the anther apices, style branches c. 5 mm long. Capsules unknown. Flowering in December and in January in Zambia and Malawi.Allied to G.dalenii but having larger pale lemon-yellow and greenish flowers, and distinctive leaves the entire surfaces of which are covered with a dense minute papillose indumentum. Both the midrib and secondary veins are typically heavily thickened and hyaline. In wetland sites such as marshes, dambos and streambanks.
