Farmelia subalbica7is sp. nov. — Similis P. siibcequa7iti sed thallo 

 pallido vel pallida cinerascente et subtus pallido. Apothecia 

 sicut in P. sub(Equante. Sporae, .0T3-.016 x .008-.01 mm. 

 Spermogonia extus nigra iniiata, peridio infra non infuscato ; 

 spermatia recta cylindrica, .007-.009 x circ. 0008. mm. 

 The reactions with C are the same in all these — viz., medulla 



C red. In the last from N.Z. the sorediiform points are few and 



scattered. 



There is still another Parmelia in my herbarium of the type of 

 P. Borreri sent by Mr Weir from the Brazils. 



Parmelia flaventior sp. nov. — Thallus flavescens vel stramineus 

 (C erythrinosus), subtus niger rugulosus fere nudus, laciniato- 

 lobatus, laciniis rotundatis, margine passim adscendentibus, 

 recurvis et tunc plerumque sorediosis, punctis vel fissuris 

 sorediosis adspersis. Spermatia recta cylindrica, .0065-.008 

 X circ. .0006 mm. Apothecia ignota. 

 There are present, besides, rufo-fuscescent, generally conglom- 

 erate, cephaloid tubercles. The reaction by C on the white 

 medulla, after the application of K, is intensely red, and the same 

 intense red is immediately produced on the epithallus by the 

 same reagents. 



From Brisbane another Par7nelia of the same type has been 

 sent by Mr T. M. Bailey, which, as to external appearance, is 

 unique; but inasmuch as both apothecia and spermogonia are 

 awanting, its final determination must lie in abeyance.

Rosa micrantha in Scotland.— So far as I am aware, this Rose has not 

 previously been found further north than Bilton, near Alnwick, in Northum- 

 berland, where it was discovered about ten years ago by Mr Chrisp. I in- 

 close examples from three Scottish stations — two in Roxburgh, and one in Ber- 

 wickshire. None of them agrees exactly with any of the southern forms that 

 I have seen ; that from the hedge or roadside near Muirdean, Roxburgh, is 

 the most characteristic. The other two — from " roadside between Kelso and 

 Yctholm, Roxburgh," and "roadside to Nenthorn, Berwickshire" — recede 

 from the type, in the prickles not being uniform, the hairy styles, the more 

 rounded base of the leaves, and in the general habit of the plant, which 

 is more compact, and the branches not so lax and flexuous as in typical 

 micrantha. — Andw. Brotherston, Kelso. 



Xylaria polymorpha. — This fungus, though rare in Scotland generally, 

 appears to be frequent in Roxburghshire, as — although not searching for fungi
