2. Puccinia heketara n. sp. (Fig. 129.)  Compositae. 0. Spermogones unknown. I. Aecidia hypophyllous and caulicolous; on leaves aggregated into irregular closely-packed groups on distorted spots, visible on the upper surface as discoloured areas; on stems scattered over irregular inflated areas which may attain a length of 25 mm., bright orange. Peridia embedded or slightly erumpent, cupulate, 0.5 mm. diam., margin lacerate, slightly reflexed, standing above the leaf-surface about 0.25 mm. Spores elliptical or obovate, 25–35 × 18–22 mmm.; epispore moderately and finely verrucose, 2 mmm. thick, hyaline; cell-contents orange, vacuolate. III. Teleutosori hypophyllous, seated on minute spots which may or may not be visible on the upper surface, chocolate-brown, circular or irregular in outline, up to 1 mm. diam., frequently less, erumpent, pulverulent. Teleutospores elliptical, 45–55 × 20–26 mmm.; apex rounded Fig. 128.—Uromyces Edwardsiae n. sp. Fig. 129.—Puccinia heketara n. sp. Fig. 130.—Uredo Forsterae n. sp. or bluntly acuminate, not or slightly (3 mmm.) thickened, base attenuate, lower cell slightly longer and narrower than the upper; constricted at the septum; epispore smooth, 1.5–2 mmm. thick, pallid chestnut-brown, cell-contents vacuolate; pedicel deciduous, hyaline, stout, up to 25 × 8 mmm.; germ-pore of the upper cell apical, basal pore between one-third and two-thirds below septum, both conspicuous and papillate. X. Mesospores rare, obovate, 28–40 × 16–23 mmm. Host: Olearia Cunninghamii Hook. f. On leaves, petioles, and stems. Herb. No. 1244. I–III. York Bay (Wellington), 100 m., E. H. Atkinson! (Type.) The host is endemic, and abundant throughout the North Island and lowland forests of Marlborough and Nelson (Cheeseman, 1906, p. 286). This rust closely resembles Puccinia Atkinsonii G. H. Cunn. (on Olearia excorticata Buch.), but differs in many minor characters, especially in the non-retuse apex, thinner epispore, and smaller size of the teleutospores.
