 —XXXI. Rhodora 21 : 125-128. 1919.— A continuation of the report of the Committee on 

 Local Flora of the New England Botanical Club. Reports species and their distribution in 

 the district about Boston, Massachusetts. [See also next preceding Entry, 342.] — James P. 

 Poole. 



344. Lindfors, Thore. Sydskandinaviska element i Frostvikens flora [South Scandi- 

 navian elements in the flora of Frostviken (Province of Jamtland, Sweden)]. Bot. Notiser 

 1919: 127-136. 1919. — The plants belonging to this element are nearly always confined to 

 localities favored with southern exposure, only exceptionally in groves on level ground with 

 calcareous soil. The author records 14 such "south-mountains" or "south-hills," and gives 

 the localities of 25 South Scandinavian plants in this region of northern Sweden. — P. A. 

 Rydberg.

346. Little, J. E. Notes on Bedfordshire plants. Jour. Botany 57:306-312. 1919.— 

 A list is given of publications dealing with the flora of Bedfordshire. The present paper 

 presents a selection of records supplementary to the "Field flowers of Bedfordshire," by 

 W. F. Bunker, 1911. Hillhouse suggested that the county be divided somewhat on the 

 basis of the surface geology into 49 divisions, a number wholly unworkable on any extended 

 scale, and not desirable for so small a county. The Victoria County History divides the 

 county on the basis of river basins, making 7 divisions, which may be merged into 5. The 

 present records all fall in Hillhouse's southern half (soil chiefly cretaceous). Rev. Chas. 

 Abbot's Flora Bedfordensis (1798) contained several names of plants not now known there, 

 and also some which were rare then but are now more common. The new records with sta- 

 tions and critical notes, are comprised in a list several pages in length. — K. M. Wiegand. 



347. Long, Bayard. Notes on the American occurrence of Crepis biennis. Rhodora 

 21:209-214. 1919. — The genus Crepis, native to the Old World, is represented in eastern 

 United States by several introduced species. It has been the consensus of opinion that 

 four of these have become well enough established to be recognized as elements of our flora. 

 Among these is C. biennis which is credited by the American manuals with a more or less 

 extended range from New England southward to Pennsylvania and westward to Michigan. 

 In verifying the records of the range of this species the writer found only one authentic her- 

 barium specimen from Pennsylvania, one from Vermont, collected by Pringle in 1875, and a 

 third collected in North Carolina in 1888. All other records were based on wrongly labelled 

 specimens of other species. Since the large collections examined showed only these three 

 authentic specimens and these from ancient collections, much new evidence is needed to 

 maintain this species as an element of our flora. — James P. Poole. 



348. Long, C. A. E. Notes from Matinicus [Maine]. Rhodora 21: 148. 1919.— Five or 

 six plants of Amsinckia Douglasiana A. DC, a native of California, were found growing in 

 and near an abandoned chicken yard on the Island of Matinicus, twenty miles off the Maine 

 coast. The identification was made by M. L. Fernald. It is as yet uncertain whether this 

 plant has become established or is a casual. — This same island is a hitherto unpublished sta- 

 tion for Typha angustifolia L., although the station has been known to the writer for a num- 

 ber of years. The most easterly station previously published was the lower Kennebec. — 

 James P. Poole. 



349. Lundequist, Olof. Nagra anmarkningsvarda vaxter fran Granna och Visingso 

 [Some noteworthy plants from Granna and Visingso (Sweden)]. Svensk. Bot. Tidskr. [Stock- 

 holm] 13: 104-106. 1919. — A list of 28 plants is given with brief notes on locality, date and 

 collector.— U'. W. Gilh rt.
