my possession from the Cape of Good Hope (^Herb. Menzies) and Nepaul 

 {Herb. Hook.), which have also been referred to P. leucomela, and perhaps in- 

 dicate an extreme state of the species, near to P. ciliaris. 



' Pahmelia Leana: Thallosubcartilagineo fragili substellato glabro albido, 

 subtus pallide fuscescenti propter margines laciniarura parciter fibrilloso, laci- 

 niis linearibus planiusculis laxe imbricatis subpalmato-muhifidis incisis midis ; 

 apotheciis subsessilibus, margins crasso integro demum flexuoso rugulosove, 



disco e rufo-nigrescentenudo. Thallus quite thin and brittle. The features 



of the apothecia appear to separate this from P. spedosa, Ach., but the discovery 

 of more perfect specimens may make necessary some modification of the other 

 characters. 



^ First distinguished in this country by the late Mr. Oakes, and referred to 

 under the name given it by him, in the Synopsis of Lichenes of New England, 

 SfC, p. 34. 



3 There are also some small and imperfect fragments of what is possibly a 

 new species, allied to P. rubra and P. carneo-lutea. I have another fragment 

 of the same lichen collected by Mr. Curtis in North Carolina. What seem to 

 be the peculiar features of these specimens may be indicated as follows: P. 

 crusta cartilaginea granulata albo-glaucescente; apotheciis elevatis extus gra- 

 nulatis, disco e concavo demum planiusculo, e pallide cerino-rufescente (demum 

 et puniceo?) margine elevato, inflexo, granulato-crenulato. The name P. grani- 

 fera will be appropriate to the state here described.
