NOTE BOTANY. 



Sper?7iogo?iia minute, prominent, reddish. Spermatia borne 

 on arthrosterigmata, straight, •oo4-"oo5 mm. long and 

 ■ooo6--ooo8 mm. broad. 



On Umestone rocks, common and generally distributed ; 

 especially abundant on seaside rocks. 



A comparison of the exsiccati quoted above with those 

 cited by Leighton under P. imiroruin^ will show that he con- 

 sidered certain states of sympagea to belong to jmirorum. 

 The spores of the two species ought,- however, always to 

 prevent confusion. The affinity of the present species with 

 callopisnia is very close, and states of the two approximate 

 ver}^ much, though in general the stouter, firmer thallus of 

 sy?npagea is very distinct from that of the other. 



Acharius, in all his works, marks the plant he describes 

 under the name of sympagea as one that he had not seen ; 

 but he cites as synonymous Persoon's Lichen auranfhis. 

 Why, under the circumstances, he changed the name, I do 

 not know. 



* * Plant imperfectly developed. 



13. Lecanora xantholyta Nyl., Flora, 1879, p. 361, and 1883, p. 107. 

 Thallus spreading irregularly, quasi-effigurate at the circum- 

 ference, nearly continuous at the centre, soft, thin, minutely 

 granuloso-leprose, citrine yellow. 

 Apothecia and sperniogonia unknown. 



On limestone rocks. Probably common in limestone 

 districts, but disregarded. 



It has been found in the South of England, near Bangor 

 inAVales, at several places in Westmorland, and in Yorkshire. 



Dr. Nylander considers it to have some affinity with 

 Lecanoj^a cir7'ochroa ; but on account of its leprose thallus, 

 and, so far as known, imperfect development, he pro- 

 visionally places it in a sub-genus, Leproplaca. 



NOTE— BOTANY. 



Carex pendula in Cumberland.— During a few days' sojourn in the 

 northern division of Cumberland, in July of the present year, I explored a part 

 of the parishes of Scaleby, Kirklinton, Stapleton, Abbey Lanercost, and Arthuret. 

 I found the Great Sedge growing luxuriantly in a wood near Shanks Castle, on the 

 north bank of the river Lyne, l^elow Racks Bridge, and above the junction of 

 Solport Burn with the main river. A little lower down I remarked several fine 

 examples of Cardinis hctcrophyllus and EquiseiH?}i niaxinnini. This latter plant 

 grows abundantly by the little river Cambeck, between Kirkcambeck hamlet and 

 Solemain. — W. Hodgson, A.L.S., Flimby, near Maryport, Nov. 17th, 1887.
