 raphy of Formosa. | [Chapter III. Botany.] Bol. R. Soc. Geogr. Madrid 60: 445-499. 1918. 

 — Chapter III of this work is devoted to a general treatment of t !.<■ flora of Formosa, taking up 



a history of publi hed work, principally that of Hat ata, Mai i i , and Kawakami, 

 then giving a partial enumeration of the plants, particularly the economic species. Fr.igoso 

 in review notes that it is a curious work without scientific pretensions but worth reading.

313. Andrews, A. LeRoy. Dlcranoweisla crispula in the White Mountains. Rhodora 

 21: 207-20S. Nov., 1919. — An account of a station established for this moss in 1917 by the 

 Cold Brook of King's Ravine in the White Mountains of New Hampshire. Also gives the 

 record of other stations at which the species is known to occur. — James P. Poole. 



314. Anonymous. Resistant chestnut. Amer. Bot. 25:25. 1919. — The suggestion is 

 made that many plants may have become extinct through the attacks of microscopic organ- 

 isms rather than through changes of climate, as usually stated. — W. N. Clute. 



315. Beauverd, Gustave. Esquisse synecologique comparative de deux marais des 

 environs de Baulmes. [A synecological comparison of two marshes in the vicinity of Bauimes.] 

 Bull. Soc. Vaudoise Sci. Nat. 52 : 17-93. 1918. — A study of two marshes, the Marais de 

 Ranees and the Marais de la Baumine, on the mid-slopes of the Jura Mountains, in Canton 

 Vaud, Switzerland. Though having the same altitude and subsoil, the two marshes have 

 notable floristic differences. The Marais de Ranees has a disjunct lowland element, repre- 

 sented by Gentiana baltica and Phyteuma tenerum. There are also tree relicts, attesting to a 

 former forest condition. The Baumine plants are of mountain affinities, the plants being 

 largely typical of subalpine pastures, such as those of the headwaters of the Baumine stream.

316. Bennett, Arthur. Vaccinium intermedium Ruthe. Jour. Botany 57:284-285. 

 1919. — A note on the occurrence of this plant in England. It was called forth by a paper in 

 the preceding number of Jour. Botany (p. 259). — K. M. Wiegand.

 any 57: 322-323. 1919. — Notes on occurrence of this plant in Great Britain. 



318. Bicknell, Eugene P. The ferns and flowering plants of Nantucket — XX. Bull. 

 Torrey Bot. Club 46:423^440. 1919. — This article forms the conclusion of the series on 

 Nantucket. In this catalogue have been listed 1136 species including 33 natural hybrids. A 

 general discussion is given of the affinities of the flora, a list is made of species with their 

 northern or eastern limit on the island, and one, of the northern species reaching their southern 

 limit here or on Long Island. The number of introduced species is also discussed. — P. A. 

 Munz. 



319. Campbell, Douglas Houghton. The derivation of the flora of Hawaii. Leland 

 Stanford Junior Univ. Publ. Univ. Ser. 34 V- 1919. — The generally accepted view as to the 

 origin of the Hawaiian Islands, which are entirely volcanic, holds that they were thrown up 

 from the ocean depths and always have been isolated; but another view, which the author 

 accepts as the most satisfactory explanation of the origin of the flora, holds that Polynesia, 

 including the Hawaiian Islands, is the remains of a once extensive land mass, either a single 

 continent or several large continental islands. — "Some such connection seems necessary to 

 explain the great preponderance of Australasian and Malaj T an types in the flora, especially 

 such forms as offer no ready means of transport by any known agency." Fifty-one genera of 

 spermaphytes and 37 species of pteridophytes occur in Hawaii which are common to the 

 Australasian-Malayan region, but not found in America, while only 6 Hawaiian-American 

 genera of spermaphytes and two species of pteridophytes are found in Hawaii and not in the 

 Australasian-Malayan region. "The great preponderance of Indo-Malayan elements in the
