No. 2, March, 1921] TAXONOMY OF VASCULAR PLANTS 213 



laurinus Sw. var. adenophyllus Cadenophyllus Spreng., Gymnanlhes Integra {G. glandulosa Pax, 

 not Muell. Arg.), and Euphorbia nirurioides {Chamaesyce nirurioides Millsp.)- — /. M. 

 Greenman. 



1436. Fernald, M. L. Some variations of Cardamine pratensis in America. Rhodora 

 22: 11-14. 1920. — In North America there occur the naturalized Cardamine pratensis with 

 pink petals; the indigenous white-flowered C. pratensis var. palustris; the pink-flowered 

 variety angustifolia of the Arctic regions which varies from the typical C. pratensis in leaf 

 characters as well as its range; and the pink-flowered double-flowered form C. pratensis forma 

 plena. A discussion of these variations, their history, and their ranges, is followed by a 

 key. The synonomy, bibliography, and distribution of each is given. — James P. Poole. 



1437. Fernald, M. L. The northern variety of Ranunculus hispidus. Rhodora 22: 

 30-31. 1920. — At the southern border of its range this plant has erect pubescence, but north- 

 ward the hirsute plant becomes rare and gradually gives way to a commoner variation with 

 pubescence appressed or even almost or quite wanting. From New England and New York 

 this plant with appressed pubescence extends westward to Iowa, and south to the mountains 

 of North Carolina, West Virginia, Missouri, and Kansas; while the typical R. hispidus 

 extends well into Georgia and Arkansas. The writer proposes this more northern extreme 

 as Ranunculus hispidus Michx.var. falsus, n. var., giving the description, distribution, and a 

 list of characteristic specimens. Many of these specimens were distributed as R. septen- 

 trionalis, a northern species of swamps and meadows with much coarser stems and leaves 

 and with stout and very long repent stolons developing soon after the expansion of the first 

 flowers. — James P. Poole. 



14.38. Fernald, M. L. Polygala paucifolia Willd., forma vestita, n. f. Rhodora 22:32, 

 1920. — The typical P. paucifolia has the leaves green and quite glabrous except for a slight 

 ciliation and sometimes a little pilosity on the midrib. This new form which the writer 

 proposes has the leaves densely pilose with canescent hairs, and is conspicuous when grow- 

 ing on account of its pale foliage. The type specimen is from the northwestern base of Fall 

 Mountain, Walpole, New Hampshire, where it was collected in 1917. — James P. Poole. 



1439. Fernald. M. L. The American varieties of F*yrola chlorantha. Rhodora 22: 

 49-53. 1920. — The author gives descriptions and bibliographies of the typical Pyrola chlor- 

 antha and of its varieties occurring in America, with a key and discussions as to the distin- 

 guishing differences between them. The varieties are published as new varieties or new 

 combinations in each case. The writer attempts no solution as to their status. — James P. 

 Poole. 



1440. Fernald, M. L. Scirpus acutus Muhl. Rhodora 22:55-56. 1920.— The writer 

 finds that when, in 1904, Mrs. Chase proposed Scirpus occidentalis (Wats.) Chase, as one of 

 four species which had been passing under the aggregate name S. lacustris L., she overlooked 

 the clear description given in Bigelow's "Florula Bostoniensis" of S. acutus, a new species 

 ascribed by Bigelow to Muhlenberg. Somewhat later Muhlenberg himself published 

 S. acutus, contrasting it with his S. lacustris (the S. validus of Mrs. Chase's treatment). 

 Bigelow's description and Muhlenberg's unquestionably define S. occidentalis, and the type 

 station, "deep water at Fresh Pond," is likewise conclusive, for S. occidentalis was often 

 collected in Fresh Pond in the days prior to its conversion into a reservoir, but the old col- 

 lections show no material of *S. validus from the pond. The writer therefore revives the 

 name Scirus acutus Muhl. The bibliography and the synonyms are given. — James P. Poole. 



1441. Fernald, M. L. A flora of the Penobscot Bay Region. [Rev. of: Hill, Albert 

 Frederick. The vascular flora of the Eastern Penobscot Bay Region, Maine. Proc. Port- 

 land [Maine] Soc. Nat. Hist. 3: 199-304. 1919.] Rhodora 22: 91-96. 1920.— See Bot. Absts.
