Short Notes
BRI 151731, status annotated by author
Calytrix islensis is a mainly glabrous shrub to 2 m tall. The leaves are closely to widely spaced, appressed to spreading-ascending with stipules to 0.2 mm long. The petioles are obsolete or to 0.5 mm long, the blade is elliptic to obovate, 2 to 3.5 mm long by 1.1 to 2 mm wide, the margins are slightly ciliate, the base gradually tapering, the apex subtruncate to obtuse and apiculate. The inflorescences consist of one to several clusters of flowers, the subtending leaves are usually obovate with a wider scarious margin than on the foliage leaves. The calyx segments are connate at the base (up to 0.3 mm long), the blade is suborbicular, 2.5 to 3 mm long by 2.8 to 3.5 mm wide, the margin erose, the apex rounded to acute, produced into a scabrid awn to 11 mm long. The petals are white, becoming yellow towards the base; elliptic to lanceolate, 6.5 to 8 mm long by 3 to 4 mm wide, the apex acute to acuminate. The seed is not known.
Calytrix islensis is quite close to C. gurulmundensis but can be readily distinguished from it by the leaf blades which are extremely broadly obtriangular in transverse section whereas they are depressed angular-obovate in C. gurulmundensis (Craven, 1987).
