Description: II. Uredosori hypophyllous, seated on pallid spots visible on the upper surface, orbicular, 1
mm. diam., bullate, reddish-orange, pulverulent, deeply buried in the dense tomentum of the
leaf-surface. Spores elliptical or obovate, 35-55. X 26-34 mmm.; epispore hyaline, coarsely
and moderately echinulate, 2-2.5 mmm., thick, cell-contents granular, reddish-orange; germ-pores indistinct.
Notes: The host is endemic, and is confined to the Marlborough District. (Cheeseman, 1906, p. 279.)
In size and shape the spores of this species resemble the preceding; it is separated on account
of the thicker, coarsely and moderately echinulate epispore, and bright reddish-orange colour
of the sori.
