OF PUCCINIA CORONATA, VAR. HIMALAYENSIS. 235 
4. Puccinia Caricis-filicine, mihi, collected 24th November, germinated 6th May, i. е. 
5 months and 12 days after. 
5. Uromyces Vossie, mihi, collected on dried over-wintered leaves in nature, ger- 
minated freely in April, probably about 5 months after ripening. 
6. Puccinia Acetose, Schum., collected 6th December, germinated freely 23rd March, 
$. е. 8 months and 17 days after. 
7. Uromyces Pisi, Pers. (from Lathyrus sativus), collected 4th April, germinated 19th 
June, %. е. 2 months and 15 days after. 
8. Melampsora Lini, Pers., collected 4th April, germinated 19th June, i. e. 2 months 
and 15 days after. 
9. Puccinia Flosculosorum, Alb. et Schw., collected 26th December, germinated freely 
on 12th March, 2. e. 2 months and 17 days after. 
I shall conclude by again drawing attention to the similarity this fungus in the :ecidial 
stage exhibits to the æcidial stage of Gymnosporangium, i. e. in the long interval which 
elapses between the eruption of spermogonia and the formation of æcidia, and in the 
very deep-seated position of the basidiallayer. These points are not in themselves of 
any real importance, but they serve to strengthen the view I had been led to form 
gradually from other considerations that the distinction between Gymnosporangium and 
Puccinia is not of generic value, The chief characters of Gymnosporangium upon which 
its generic distinction is based are :— 
(a) The gelatinous nature of the stalks of the teleutospores ; 
(5) The displacement of the germ-pore of the upper cell of the teleutospore from 
the apex to near the septum ; 
(c) The plurality of germ-pores to each cell of the teleutospore ; 
(d) The absence of uredospores ; and 
(е) The peculiar characters of the æcidial fructification, 4. e. the length of the peri- 
dial tubes, the depth to which they penetrate within the lamina of the 
leaf, and the long interval between the production of the spermogonia and 
the ecidia. 
With reference to (a), I have myself shown elsewhere * that a gelatinous sheath to 
the stalks of the teleutospores is not peculiar to Gymnosporangium, occurring as it does 
(though to a minor extent) in Puccinia Prainiana, mihi (Сеота Smilacis, Barclay), 
and as De Bary has also depicted in the case of P. Berberidis, Montagne 7. 
With regard to (5), although I know of no Puccinia which shows a displacement of 
the germ-pore of the upper cell downwards, yet I have met with two species in which 
this occurs in the lower cell, namely in Puccinia Geranii-sylvatici, P. Karst., var. 
himalayensis, and Р. Wattiana, mihi 1, on Clematis Gauriana, Roxb.
