Diagnosis

Linear leaf, up to at least 50 mm long, 1.3–2.2 mm wide, tapering imperceptibly into a proximal constriction just distal to abruptly swollen and decurrent base. Apiculate to mucronate apex, commonly missing. Stomatal groove depressed with overhanging margins, up to 120
m (average 50
m), never exceeding one-fifth of the groove width; in some cases there are regions along this groove where there are no overhanging margins. Groove in a point just below the apex. Cuticles 10–20
m thick. Stomatal density within the groove 140–170 per mm2. Stomatal orientation preferentially longitudinal. Stoma typically 70–110
m long and 60–90
m wide. Stoma with 4–7 subsidiary cells, one always in each polar position. Subsidiary cells, non-stomatal cells inside the groove and margins each bearing one single short blunt papilla. Mesophyll with 3–7 resin ducts.
