| Brief Description: |
This broad-leaf species that is acaulescent and rhizomatous has many leaves (up to 16) forming a rosette. The somewhat flexible leaves are 60-104 cm long and 7-10 cm wide with a 3 mm thickness mid-leaf. They are erect to recurved and spreading and have a broad central channel that folds in the dry season. The leaves narrow downward but do not have a petiole, and they also narrow upwards to a soft but firm tip. The leaves are medium green in color with lighter green mottling and some banding, and the margin is reddish-brown in color with a thin white edge that has some fibrous shredding. The inflorescence is 74-92 cm tall and simple with 4 - 8 flowers per cluster. |
| Similar Species: |
This species is rather unique within the group of broad - leaf sansevierias from Uganda. It bears some similarities to Sansevieria frequens and S. raffillii, as well as Sansevieria dawei, but the rosette with numerous leaves tends to make it distinctive. |
