Sansevieria |
| Group: |
Sansevieria dawei |
| Etymology: |
This species is named for the Yumbe District of northern Uganda where it was found. |
| Distribution: |
Northern Uganda in an east-west band south of the border with South Sudan. |
| Brief Description: |
This is an acaulescent, broad-leaf rhizomatous species with usually 4-7 (up to 11) lanceolate leaves 86-170 cm long and 8-10 cm wide. The leaf base is slightly narrowed, and the leaves may be erect, spreading, or recurved, usually bending near the midpoint. The smooth medium-green leaves have a reddish margin, are vaguely guttered, and taper to an acute but soft tip. The inflorescence is simple, 60-83 cm tall and about a 0.7 cm in diameter, and is sometimes corrugated. The fertile portion is about 2/3rds of the inflorescence length and is densely flowered with 1-5 flowers per cluster. |
| Similar Species: |
Sansevieria yumbiensis is related to other Ugandan species, particularly Sansevieria newtoniana, but that species occurs in southern Uganda and northwestern Tanzania. S. marachiensis grows closer to the west, but that species has banding and blotching whereas S. yumbiensis only has those characteristics in its juvenile form. Sansevieria coleana and S. conduplicata occur to the southeast and east, respectively, and are unlikely to be confused with S. yumbiensis. This species has a preference for deep shade on termite mounds. |
