Peronospora grisea (Unger) Unger 1847

From inoculation experiments carried out by Jafar (1962) conidia from the different Hebe spp. failed to infect plants of a different species of Hebe. Morphologically the fungus on Veronica is identical with that on Hebe. Downy mildew has at times caused losses of plants of Hebe spp. in nurseries in the Auckland area. Hebe and Parahebe spp. are indigenous to New Zealand.
