T. H. BUFFHAM ON SOME FLORIDE^. 187 



pollinoids attached to the trichogyne in the act of fecundation 

 were noted. 



Ptilothamnion Pluma Thur. The development of the female 

 organs is fully described by Bornet in Notes Algol., p. 179, 

 Plate XL VI. 



Griffithsia 'setacea Ag. The trichogyne is very slender and 

 delicate. 



Halurus equisetifolius Kiitz. (Griffithsia equisetifolia Ag.). It 

 is of a similar character in this species. 



Callitliamnion friiticulosum J. Ag. (Not in Phyc. Brit.) 



Compsothamnion gracillimum Schmitz. A figure of this is 

 given by Schmitz as Callithamnion gracillimum (Untersuch 

 ilber die Befruchtung der Floridece). The trichogyne is swollen 

 near the base. The fruit differs considerably from that of the 

 typical Callitliamnia. 



Ptilota plumosa Ag. The trichogyne is stout, but not very 

 long. 



Bumontia filiformis Grev. The trichogyne is long, stout, 

 brown, and conspicuous. It arises from cells very little below 

 the cortex. Naccarria Wiggii Endl. 



1 will conclude with a few notes including some observations 

 of the association of two kinds of organs. 



Gonimophyllum Buffhami Batt. I have a specimen where a 

 male leaflet is growing laterally out of the pericarp of a nearly 

 mature cystocarp. In another case there arise from the same 

 basal cushion one leaflet covered with procarps, and three 

 tetrasporic leaflets. When this curious parasitic alga was first 

 published {Journal of Botany, 1892, March, Plate CCCXIX) it 

 had not been observed on female specimens of Nitophyllum 

 laceratum, and only from Deal. Since then I have seen it on 

 cystocarpic specimens of that host, and also on the plant called 

 N. rejptans Crn./and have taken it myself at Torquay (Aug. 

 1894) 



With regard to N. reptans, described and figured by the 

 brothers Crouan (Florule du Finistere, p. 152, Plate XXI.), and 

 distinguished by its prostrate habit and its adhering to the 

 substratum by numerous root-like processes from its inferior face, 

 I received from Mr. J. T. Neeve, of Deal (October, 1891), some 

 specimens of N. laceratum Grev. in situ. It would appear that 

 usually this species is torn from the substratum and thrown up
