Romanzoffia tracyi is a rare plant (classed on the BLUE list) (1) This land plant with perennial leaves, is often referred to as mist maiden. It grows (to 10cm only) on ocean bluffs on Southern Vancouver Island and the adjacent mainland south. For several years two small patches grew on the center island. One was at the very top of the highest rock cliff on Great Race Rock and this one by 1988 had disappeared. The other, five meters NW of the boathouse was obliterated by the rock blasted from the helicopter pad in the late 1970's. Since the mid 1990's it has again been observed growing scattered among the large rock rubble close to where it had originally been established above the boathouse. In 2000, a new site has been found just east of the SE corner of the Guardian's house. In a floristics survey done of the island in the spring of 2001 by two students, Julia and Taarini, several clumps of the plant were found in a number of new locations on the island, notably to the South West corner of the keeper's house. Physical appearance This plant has perennial leaves which are heavy with a protective wax covering. Romanzoffia tracyi grows to a maximum height of 10 cm. It grows brownish-woolly tubers, has 5 to 8 rounded lobes and petioles 2 to 3 times as long as the leaves. The blosssoms are delicate and white funnel-form in few-flowering spikes (flowers from March to May). The flower stems are short and are called peduncles with hairy clayx lobes.(3)(4) Potential research question Romanzoffia tracyi is only located in ocean bluffs where it is possible for the plant to be in contact with salt sprays. Why are thse salt sprays necessary for the location of this plant?
