Article: McKenzie, E.H.C. (1988). Puccinia freycinetiae sp. nov. on Freycinetia baueriana ssp. banksii. New Zealand Journal of Botany 26(1): 99-100 (http://www.rsnz.org/publish/abstracts.php).
Description: Aecia not known. Uredinia amphigenous, mainly on lower (abaxial) surface, cinnamon-brown, pulverulent, 0.75 mm long. Urediniospores (25-) 27-33 (-40) x 22-25 (-27) µm, globose or broadly ellipsoidal, wall 2.5-3 µm thick, golden to cinnamon-brown, echinulate, germ pores 2-3, equatorial, with inconspicuous caps. Telia similar to and arising from the same sori as the uredinia, blackish-brown. Teliospores (32-) 36-45 (-50) x (15-) 17-20 (-21) µm, constricted at septum, wall 0.5-1 µm thick at sides, 4-8 (-10) µm at apex, smooth, golden-brown apically, paler basally, upper cell subglobose or ellipsoidal, lower cell obovoid or ellipsoidal; pedicels up to 25 x 5-7 (-12) µm, persistent, pale brown.
Notes: Although the host is common and widespread in New Zealand, the rust is known from only the one specimen.
The type specimen of Uredo freycinetiae, for which only uredinia were described, was examined and found to differ from Puccinia freycinetiae, particularly in morphology of the uredinia. The hypophyllous uredinia of U. freycinetiae are very small (c. 100-160 µm diam) and grouped on a slightly discoloured area of the leaf. The uredinia are subepidermal, pycnidioid, with a 25-40 µm wide ostiole. The hyaline urediniospores are 25-29 x 23-27 µm, globose or broadly ellipsoidal, coarsely echinulate, with a wall 1.5-2.5 µm thick, and lack obvious germ pores.
P. freycinetiae is distinct from U. freycinetiae. The uredinium of U. freycinetiae is typical of some Phakopsora spp.

Description: Type: Rust and Smut Fungi; Description: Uredinia cinnamon brown, 0.75 mm long; mainly on the lower surfaces of leaves. Urediniospores globose to broadly elliptical, 25–40 × 22–27 μm, echinulate, golden to cinnamon brown. Telia similar to and arising from the same sori as the uredinia, blackish brown. Teliospores elongate-oblong to subclavate, 1-septate, 32–50 × 15–21 μm, smooth, golden brown; pedicel persistent.
Distribution: Distribution: Taranaki.; 1st Record: McKenzie (1988).
