Hesperantha is a cormous genus in the Iridaceae family from southern and tropical Africa. Species D-J are found on this wiki page. See the links below for information about this genus and other species.
Hesperantha erecta has creamy white flowers which open in the afternoon. Some populations are acrid musk scented. It is found on granite outcrops, granitic sands, sandveld and renosterveld in the northwestern and southwestern Cape. It blooms late winter to early spring and is pollinated by bees.

Hesperantha falcata is widespread growing on sandstone and shale slopes and coastal flats from the Northwest Cape to the Eastern Cape. It has white or yellow flowers, with the outer tepals brown or red. The white fragrant (jasmine to frangipani or acrid musk scented) flowers open late in the afternoon or evening and the yellow unscented flowers during the middle of the day. It is pollinated both by bees and moths. The white flowers are very similar to Hesperantha cucullata, but are smaller and the corms of each species are different.

Hesperantha grandiflora is an erect species that grows from 15 to 70 cm and is found in damp grassy and often shady places or forest margins, cliffs and near streams. It is endemic to the Drakensberg. Flowers are large and pink and open during the day. This species has a tube that is bent so the flowers face to the side with the tepals held vertically. Stamens and style branches are unilateral with anthers and style arms arching downward. This species is pollinated by long proboscid flies. It flowers in the wild from January to April.

Hesperantha humilis is a short plant with deep pink to reddish flowers that open in the day when the temperatures are warm enough. It flowers winter to spring and is found growing on sandstone and shale slopes, mainly in renosterveld. The first two photos from Bob Rutemoeller show plants grown from Silverhill Seeds blooming January 2004. Two more pictures show the front and back of blooms from the same descendants of the plants of 2004 blooming in January 2008. The final photo shows the corms on a 1 cm grid. Photos by Mary Sue Ittner
Hesperantha huttonii grows in Afro-montane forests where it flowers profusely, often in light shade, on cliffs, along forest roads and streams in the Eastern Cape mountains. Growing to 30 cm, this species which blooms in fall, has pale pink flowers in a long slender floral tube. Photos from Cameron McMaster taken in the Eastern Cape including a picture of a rare white form seen in the forest below Mt. Kubusie. This species is open during the day, odorless and pollinated by long proboscid flies.
Photos by David Pilling; the scale in photo 3 is 1 mm; the pot in photo 4 is 3 inches square. The point here is that flowering size bulbs are tiny.
