No. 1, October, 1920] TAXONOMY OF VASCULAR PLANTS 55 



397. Fernald, M. L. Rubus idaeus and some of its variations in North America. Rho- 

 dora 21: 89-9S. 1919. — A discussion presenting new evidence as to the status of R. idaeus 

 and its varieties, especially those in North America. Descriptions of the varieties are given 

 in considerable detail, their synonyms as given by various authors are discussed, the varieties 

 are contrasted with each other and with the typical B. idaeus, and their distribution is given. 

 By neither Focke nor Rydhkkh was A. idat us (typical) admit 1 eel as more than an in1 roduced 

 plant in North America, but the writer presents evidence of it being indigenous on the Magda- 

 len Islands, in Minnesota, North and South Dakota, and presumably elsewhere. A key to 

 the variations of this species in eastern America is given with the bibliography and distribu- 

 tion of each. A bibliography of the species confined to western America is also given. — James 

 P. Poole. 



39S. Fernald, M. L. Bidens connata Muhl., var. gracillipes, n. var. Rhodora 21: 103- 

 104. 1919. — The writer gives a description of this new variety, also a list of characteristic 

 specimens and the stations where they were collected, the latter all located on Cape Cod. A 

 comparison of this variety with the somewhat similar B. connata var. petiolala (Nutt.) Far- 

 well, and with the typical B. connata, is also given. — James P. Poole. 



399. Fernald, M. L. Two new Myriophyllums and a species new to the United States. 

 Rhodora 21: 120-124. 1919. — Description, distribution, and bibliography of Myriophyllum 

 exalbescens n. sp. This species has heretofore passed as M. spicalum L. in America. The 

 writer points out, however, several differences between the latter species, which is of Eurasia, 

 and the American plant. Description, distribution, and bibliography of .1/. magdalense n. sp. 

 This species which occurs in the Magdalen Islands is like M. exalbescens in foliage and in the 

 whitening of the stem upon drying, but is proposed as a new species because the fruit is so 

 unlike that in the latter species. Other points of difference are noted. In the Gray Her- 

 barium among the various species which have been erroneously called by their collectors 

 Myriophyllum verticillatum , the writer found a sheet from Farewell Bend, Crook Co., Oregon, 

 collected in July, 1894, by J. B. Leiberg (no. 465) which proved to be a well known species 

 of the southern hemisphere, M. elatinoides Gaudichaud., one of a group of species confined 

 to southern Australia, Tasmania and New Zealand, and America, but not known in Africa 

 or Eurasia. It has never before been reported north of Mexico, but a foot-note to the writer's 

 article states that since this article went into type a sheet has been received from Prof. 

 Morton E. Peck, collected in Des Chutes River, Oregon, July 27, 1914 (Peck no. 571S).—

400. Fernald, M. L. A new Polygonum from southeastern Massachusetts. Rhodora 21 : 

 140-142. 1919. — While exploring the ponds of Plymouth, Massachusetts, in 1913, the author 

 noted a strictly indigenous annual Polygonum of the sandy pond-margins which was obviously 

 related to P. Persicaria L. but which had more slender and more richly colored spikes. In 

 explorations made in 191S the plant was found to be universally distributed on Cape Cod, 

 and everywhere a plant strictly of the pond margins, while P. Persicaria was naturally abun- 

 dant near houses and about the farms. The indigenous species held its own peculiar differ- 

 ences with constancy, and more detailed study in the herbarium brought out other points of 

 difference which justify the description of this plant as Polygonum purilanorum n. sp. The 

 description and the distribution of the species are given, with comments on the relationship 

 with, and the distinguishing differences between this and allied species. — James P. Poole. 



401. Fernald, M. L. The identity of Angelica lucida. Rhodora 21: 144-147. 1919.— 

 Angelica lucida was described by Cornut in his "History of Canadian Plants" in 1635. It 

 was soon cultivated in various gardens of Europe, described in numerous works of the ISth 

 century, and was taken up by Linneus in the "Species Plantarum" (1753) as a valid species 

 under Cornut's original name. The species was accepted by post-Linnean authors but after 

 1840, when Torrey and Gray cast a doubt upon it, the plant was omitted from most subse- 

 quent treatments of the American flora. Subsequently to the publication of the statement 

 by Torrey and Gray, however, Dr. Gray had for a time surmised that the seashore Angelica
