Infected leaves showed discolored or brownish spots which became necrotic in time. Houttuynia cordata is a new host for this foliar nematode.
Hylocereus sp. (a 3-angled cactus) - Rotylenchulus reniformis Linford & Oliveira, 1940, reniform nematode: Extracted from roots of this ornamental cactus (Orange County; N99-96; William L. Robinson; 22 January 1999). Swollen female nematodes with egg masses were observed on the roots of this cactus. Hylocereus sp. is a new host for the reniform nematode.
Ligustrum japonicum (Japanese privet, category II species on Exotic Pest Plant Council list) - Meloidogyne incognita (Kofoid & White, 1919) Chitwood, 1949, southern root-knot nematode: Extracted from roots of declining plants of this ornamental shrub (Orange County; N99-400; Barbara J.
