Description: 0. Unknown.
I.
Aecidia amphigenous and caulicolous, crowded in scattered groups up to 25 mm. long,
seated on slightly inflated, discoloured spots, orange. Peridia copulate, 0.25 mm. diam., 1
mm. high, margins erect, not revolute, laciniate, white. Spores polygonal or subglobose, 18-24 mmm.
diam.; epispore tinted yellow, densely and minutely verruculose, 1-1.5 mmm. thick,
cell-contents vacuolate, orange.
II. Uredosori amphigenous, chiefly hypophyllous, and caulicolous, on leaves scattered,
orbicular, up to 1.5 mm. diam., seated on pallid yellow spots; on stems linear, up to 3 mm.
long, seldom confluent; orange-yellow, bullate, pulverulent, surrounded and partly covered by
the ruptured epidermis. Spores elliptical, obovate, seldom globose, 18-30 X 16-22 mmm.;
epispore tinted yellow, sparsely and moderately echinulate, 1-1.5 mmm. thick, cell-contents
granular, sulphur-yellow; germ-pores 4, equatorial, obscure.
III. Teleutosori similar to the uredosori but chestnut-brown. Spores subclavate or elliptical,
30-40 X 18-26 mmm.; apex rounded, not thickened, base attenuate, lower cell narrower than
the upper; slightly constricted at the septum; epispore coarsely warted, chestnut-brown, 2-2.5
mmm. thick, cell-contents granular; pedicel persistent, hyaline, fragile, up to 25 X 7 mmm.;
germ-pore of the upper cell apical, conspicuous, basal pore 3/4 below the septum,
conspicuous.
Notes: The host is endemic, and is confined to the mountains of the South Island. (Cheeseman, 1906,
p. 218.)
This species is characterized by the coarsely-warted epispore of the teleutospore.

Notes: Both the host [Anisotome filifolia] and rust are endemic; the rust occurs only in north
Canterbury.
