FURTHER OBSERVATIONS ON PROTANDRY AND PROTOGYNY. 339 



fi^-iires tlie spores, and did not observe the basic) i;i from which they pro- 

 ceed ; he therefore phiced the funi>-iis in a Hyphoinycetal j^enus. He has, 

 however, accepted VVoroniu's observations, and siibstitnted Eaohasidinm 

 in his ' Beitrage zur Kenntniss der ilheinischen Pdze,' p. 26, for the name 

 nnder wiiich he first described the species, and places it amongst the 

 Auriculurini. 



The following are all the at present known localities for this plant ; it 

 probably only requires looking for to be found in many others. St. 

 Petersburg (VVoronin); North Germany, frequent (Rabenhorst, Fungi 

 Europsei, sub n. 13S4) ; Khine Valley near Oestrich and Black Forest, 

 not far from Friburg (Woronin) ; Scotland, I'erthshire (Broome) ; Balloch- 

 buie Forest, Braeinar (E. M. Parkhurst). 



Another fungus, Cnlyptospoi-a Gfjeppertiana, Kuhn (' Hedwigia,' 1869, 

 pp. 81, 82), affects the branches of Faccinuim Fitls-Idrea in a very curious 

 way ; Rabenhorst remarks that in the neighbourhood of ileichenhall 

 (Bavaria), where it is found, the Exobasidiuni, so frequent in North 

 Germany, appears to be absent. This has not been met with in Britain, 

 but should be looketl for. 



In the Trossachs I also found a species of RJi/jfisina, parasitic upon V. 

 Vitis-Id^a. This has not apparently been described, but it is in too im- 

 mature a state to admit of determination. Provisionally it may be re- 

 ferred to R. Androuiedce, Fr. 



FURTHEE OBSERVATIONS ON PROTANDRY AND 

 PROTOGYNY. 



By Alfred W. Bennett, M.A., B.Sc, F.L.S. 



I have been able to make a few more observations during the past 

 summer and winter, on the relative period of the maturing of the nuile 

 and female reproductive organs in continuation of those already puijlislied 

 in the 'Journal of Botany ' for October, 1870 (Vol. VIII. p. 315), which 

 it may be worth while to record. The observations were made this year, 

 in the latter part of August and early part of September, and in the 

 southern counties of Cornwall, Devon, and Surrey. Not having my pre- 

 vious paper at hand, I noted down my observations independently, and 

 only compared them subsequently. liy far the majority of the species 

 observed I hnd placed under tlie same head as last year; but the lines 

 separating the three groups of Prolandrous, Synacmie, and Protogynous 

 ilowcrs (to adopt the nomenclature then suggested) not being an absolute 

 one, a few have passed over, as 1 should have ex|)ected would be the case, 

 from a group to an adjoining one. Thus Putodllla Turmeutilla, Riihiis 

 frnticosus, D'u/itnlls picrpiiren, and Euphrasia nJficinaHs, set down, in 1870, 

 as synacmie, I find noted, in 1871, as jjrotandrous ; while, on the other 

 band, Ficia Cracca, Circcea lutetlana, and Convolvulus sepintn, previously 

 recorded as protandrous, are now thought to be synacmie. In two species 

 only is there a still wider divergence in my observations than tins — 

 Spiraa Ulmaria and Enjlkraa Centaiirium. The specimens examined of 

 these plants last year were distinctly protogynous ; while during the pre- 

 sent year, on the other hand, the anthers appeared to reach maturity at a 

 decidedly earlier period than the stigmas. It would be very interesting
