Merciera

For inf! A     It appears the plant you saw is a Merciera and there are two or more. These look most like the azurea or the tenuifolia. Interestingly both share the same category on the Red List as VU (vulnerable) D2 (dunno what that means yet). It appears that in the flower, the difference is in the length and shape of the 'stem' of the flower (behind the petals, I see it's called a 'corolla tube'. Thought that was a car!). One is funnel-shape or tapered, the other thin and straight (cylindrical). The photos sent in to i-spot are not confident in their classification, even well known botanists say 'it might be that'! Regarding the leaves, on the tenuifolia there are 'tufts of small leaves in the leaf axils'. There's even another Merciera eckloniana (slender tubebell) which 'is a more slender species with scattered leaves' (compared with what, I ask?). Red data status LC 'least concern') All are members of the campanula group / family (dunno which is the right word), as are the Roella! Merciera comprises six species, all restricted to the Cape Floristic Region.  Where is the plant and is it safe? It would be good for you or me to take more detailed pictures. Certainly your pic shows in places a long slender stem to the flower. Pippa calls for a Full Environmental Report! Well spotted! This is an interesting subject! :-) A
