322 TAXONOMY OF VASCULAR PLANTS [BoT. Absts., Vol. VII, 



2198. Fernald, M. L. A new Digitaria from New Hampshire. Rhodora 22 : 101-104. 

 1920. — The plant discovered by the late F. W. Batchelder in northeastern Hillsboro County, 

 New Hampshire, in 1901, and distributed to various herbaria by the collector as Syntherisma 

 filiforme (L.) Nash, is quite distinct from the latter and is published as Digitaria laevi- 

 glumis n. sp. The author gives a list of transfers found necessary in organizing the North 

 American material of Digitaria in the Gray Herbarium, noting the synonomy involved in each 

 case. — James P. Poole. 



2199. Fernald, M. L. Oxalis montana. Rhodora 22: 143-144. 1920.— The author pre- 

 viously pointed out (Rhodora 20: 76-78. 1918) several characters by which the northern 

 wood sorrel of eastern America differs from the Old World 0. acetosella L., and took up for 

 the American plant the name 0. americana Bigelow (1824). He now finds that this plant had 

 been properly named by Rafinesque in 1818 and therefore should be known as 0. montana 

 Raf . The following new combination is made : 0. montana Raf . forma rhodantha {0. ameri- 

 cana Bigelow forma rhodantha Fernald). — James P. Poole. 



2200. Fernald, M. L. Pyrola rotundifolia and P. americana. Rhodora 22: 121-123. 

 1920. — In a former paper (Rhodora 4: 201. 1904) the author pointed out the distinctions 

 between the northern Eurasian Pyrola rotundifolia L. and the AUeghenian P. americana 

 Sweet. More recent material from Newfoundland bridges somewhat the gap between the 

 two plants. These Newfoundland plants seem to be inseparable from the Eurasian P. 

 rotundifolia L., var. arenaria Mert. & Koch, the latter differing in no morphological charac- 

 ter from the continental and more southern P. americana Sweet. The Newfoundland plant 

 is now published as P. rotundifolia L. var. arenaria Mert. & Koch, and the continental form, 

 distributed from Nova Scotia westward to Minnesota and South Dakota and southward to 

 Georgia, becomes P. rotundifolia L. var. americana (Sweet) n. comb. — James P. Poole. 



2201. Gagnepain, F. Aetheocephalus, nouveau genre de Composees. [Aetheocephalus, a 

 new genus of the Compositae.] Bull. Mus. Hist. Nat. [Paris] 26: 172-173. 1920.—^. Thorelii 

 is published as the representative of a new genus previously recognized by Thorel in manu- 

 script only. This plant of southeastern Asia is placed in the tribe Helianthoideae and sub- 

 tribe Coreopsideae. — E. B. Payson. 



2202. Gamble, J. S. The flora of Madras III. Bull. Misc. Inf. Kew 1920: 49-57. 1920.— 

 A collection of miscellaneous notes on various species included in the 3rd part of the "Flora 

 of Madras" intended to supplement that work. The following new combinations are made: 

 Syzygium Fergusoni {Eugenia Fergusoni Trim.), S. olivifolium {Eugenia olivifolia Duthie). — 

 E. B. Payson. 



2203. Godfery, M. J. Cephalanthera Richard or Epipactis Crantz? Jour. Botany 58 : 69-74, 

 1920. — The author takes exception to R. von Wettstein's treatment of Cephalanthera, Epi- 

 pactis, and Limodorum in which these three genera are united. Wettstein criticised the 

 work of Richard, Reichenbach, and Bentham and Hooker, attempting to show that the 

 characters used by them were overdrawn, and in many cases were not of a basic nature. 

 Godfery holds that Wettstein himself was in error, and that these characters proposed by the 

 older authors are sufficient to warrant the retention of the three genera. The characters 

 under discussion relate to the presence or absence of a rostellum, single or tetrad pollen, 

 shape of the stigma, shape of the anther, and degree of divergence of the perianth. One 

 species, C. cucullata which Wettstein considers transitional Godfery believes to be a prob- 

 able bigeneric hybrid of Cephalanthera and Limodorum. The author suspects that Wettstein 

 was prejudiced by his bias against the probability of the occurrence of bigeneric hybrids. — 

 K. M. Wiegand.

 Adv. Sci. 1919:331. 1920.
