12. Uredo wharanui n. form-sp. (Fig. 124.) 
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. 
Host: Olearia insignis Hook. f. On leaves. Herb. No.778. Woodside 
Creek, Wharanui (Marlborough), E. H. Atkinson! 3 Nov., 1922 
he 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. 
The following species and form-species have been recorded as occurring 
in New Zealand, but, as I have not seen specimens, I am unable to give 
` descriptions ; moreover, as in most instances the published descriptions are 
so fragmentary as to be useless for comparative purposes, I have not 
included them here. 
(a.) Uromyces Azorellae Cke., Grev., vol. 10, p. 2, 1890. 
Host: Azorella trifoliata Benth. et Hook. f. (Pozoa trifoliata Hook. f.). 
Collected in Hawke's Bay by Colenso. 
(b.) Uromeyes citriformis Berk., Fl. N.Z., vol. 2, p. 210, 1855. 
Host : “ On leaves of some orchid, apparently a Thelymitra.” 
U. citriformis Bab. (Hdbk. Fl. N.Z., p. 625, 1864) is an error of com- 
pilation. Mr. Mason, Imperial Bureau of Mycology, Kew, states that there 
are no specimens of this species at Kew or the British Museum. As no 
Specimens are known, and as the description is too imperfect for determina- 
tion, and as the host also is unknown, it would be advisable to discard this 
name. 
(c.) Uromyces scariosus Berk., Fl. N.Z., vol. 2, p.195, 1855... 
Hosts : Geranium dissectum L. and G. microphyllum Hook. f. (= Geranium 
potentilloides Hook. f. 
Collected in Hawke's Bay by Colenso. 
(d.) Puccinia novo-zelandica Bubak, Sitz-ber. Boehm. Ges. Wiss., p. 5, 1901. 
P. compacta Berk., Fl. N.Z., vol. 9, p. 195, 1855. 
Host: Myosotis capitata Hook. f. 
These specimens were said to have been collected in the South Island, 
but the host is confined to the Auckland and Campbell Islands. (Cheese- 
man, 1906, p. 463.) 
(e.) Aecidium Anisotomes Reich., Ardt. Sitzungber. K. Akad. der Wissensch., 
1865. 
Host: Angelica geniculata Hook. f. 
Possibly Puccinia cuniculi G. Н. Cunn., although the description does 
not agree with that of the aecidium of this host.
