Hah. Found, in one or other of its forms, in both hemispheres, in ahuost all 

 the tropical and temperate parts of the world, in the New as well as the 

 Old, from Lapland, in about 67° N., where it is very rare {Wahlenherg), to Aka- 

 roa, in New Zealand. Without repeating several stations given by Agardh, I 

 shall offer the following from my herbarium, together with brief notices on any 

 peculiar varieties. 



a. glabra ; — the common form abounds in Europe and North America and Nor- 

 thern Asia, where it is generally glabrous ; in the Scottish Highlands, found at 

 an elevation on the mountains of nearly 2000 feet above the sea-level, and there 

 attaining a height of 5-6 feet in sheltered situations. Altai, Ledehour. Avatshka 

 Bay, Kamtscliatka, Seemann (i)innae and segments, like some of the North Ame- 

 rican forms). Messina, Madeira, Cape of Good Hope, where, however, the more 

 common form is our var. )3 ; Macgillivray and Milne send specimens from Table 

 Mountain, with small, obtuse, pinnatifid, sterile pinnules, well represented in 

 Schkuhr, Fil. t. 96 a. Hongkong, Champion, common ; with larger pinnules and 

 segments from Chusan, Dr. Alexander, and South China, Seemann, n. 2390,

 New Jersey, M'Nab; Kentucky, Dr. Short ; New York and New Jersey, Dr. 

 Torrey ; New Orleans, T. Drummond and Teinturier ; some of the entire and

 Agardh has named these in my herbarium PL Nov(B-Angli<e, Bory, MS.) ; St. 

 Louis, Missouri, Dr. Engelmann. South America : Boquete, Yeraguas, and Sierra 



* Other synonyms might be added, if it were worth encumbering our pages with 

 them. Presl has in this group his Allosorus villosus, A. Hottentottus, A. Tau- 

 ricus ; Fee a Pt. vUlosa, which Mr. T. Moore refers hither ("excluding Cuming, 

 n. 408"), etc. etc. Mr. Moore has twenty synonyms under the European Pt.
