Distribution
Crinum binghamii is so far only known from the Western Province of Zambia
Ecology
It grows in swampy areas on black clay soils at an altitude of about 1000 m.
Morphology Leaves
Leaves 9 - 11 per bulb, up to 75 x 2.5 cm, green, whitish in the basal part, distichous to sub-distichous, rigid, erect or suberect, gradually narrowing from the base with almost all apices entire, with a midrib visible from the abaxial side, deeply channelled or canaliculate, U-shaped, with thick woolly fibres, leaf in cross section with chlorophyllous cells in rings around air channels, and vascular bundles alternating with fibre bundles
Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Anthers black, 2 - 2.5 cm long
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments arcuate, 6.8 - 7.5 cm long, dark red in distal half
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary up to 2 cm long and 0.8 cm wide
Morphology Reproductive morphology Flowers Gynoecium Style
Style dark red distally, protruding about 10 cm, stigma punctuate.
Morphology Reproductive morphology Flowers Pedicel
Pedicel 0 - 1 cm at anthesis
Morphology Reproductive morphology Flowers Perianth
Perianth tube 12 - 16 cm long, reddish green, perianth segments pure white, drooping at anthesis, 10 - 12 cm long, outer 1.6 - 1.8 cm wide, hooded apically, inner 1.8 - 2.0 cm wide
Morphology Reproductive morphology Inflorescences
Inflorescence with up to 11 flowers
Morphology Reproductive morphology Inflorescences Bracts
Involucral bracts reddish, erect in bud, later drooping
Morphology Reproductive morphology Inflorescences Peduncles
Peduncle from outside the leaf cluster, reddish, 55 - 70 cm long
Note
The new species resembles Crinum buphanoides in having radially symmetrical star-shaped flowers and distichously arranged leaves, but differs in the whitish, relatively small, aggregated bulbs, in the distinctly succulent, rigid, erect to suberect, narrow U- shaped leaves which are up to 2.5 cm wide, with intact apices and thick woolly fibres exposed when torn, in the longer peduncles (55 - 75 cm long) and fewer flowers (up to 11). In comparison, C. buphanoides possesses large, solitary bulbs covered with thick layers of brown papery scales, arching leaves 6.5 - 15 cm wide with necrotic apices, without woolly fibres, and umbels of 13 - 50 flowers. C. buphanoides occurs in drier habitats, unlike C. binghamii which is exclusively a swamp plant. Molecular data (to be published soon) show unequivocally that Crinum binghamii belongs in a clade with the Guineo-Congolian (West African) C. purpurascens and C. natans, and not with the geographically closer Zambesian C. buphanoides and C. subcernuum.
Type
Zambia, Western Prov., Senanga Distr., Sana plain, along Lyabwa canal, near the Muoyo Village, 15°34'23.5"S 23°15'7.8"E, 1035 m a.s.l., locally abundant in black wet clay soils, 30 Nov. 2003, Nordal & Kwembeya 4789 (holotypus O; isotypi K, SRGH).
Vegetative Multiplication Bulbs
Bulbs white, aggregated due to efficient vegetative propagation, bottle-shaped, with a prominent rhizomatous part below, gradually narrowing to a neck above, total length about 25 cm, largest diameter up to 9 cm
