124 Pteridophyten. — Floristik und Systematik der Phanerogamen. 



Peculiarities of leaf-shape, oi vernation and of the spore-bearing members 

 are fully described and figured. The species is said to be very distinct.

Bulletin. Vol. XI. October 1903. p. 97—105.) 



A list of 76 species and 19 varieties of Pteridophyta accredited to 

 the state of New York. Four general regions are recognized: 1. the 

 Littoral, comprising Long Island and Staten Island, to which 

 Woodwardia areolata, Lycopodium alopecuroides and L. alopecuroides 

 adpressum are peculiar; 2. the Catskill Mountain region, where in 

 3 southern species (Asplenium Bradleyi, A. montanum, and Cheilanthes 

 vestita) reach their northernmost limit; 3. the Adirondack region, 

 where several boreal forms, viz : Nephrodium fragrans, Polystichum 

 Braunii, Woodsia glabella, W. hyperborea, Lycopodium annotinum pun- 

 gens and L. Sitchense, come nearly or quite to their southern limit; 4. 

 the Western region, noteworthy for the presence of Scolopendrium 

 and many forms of Botrychium. One new name is proposed: Botrychium 

 obliquum tenuifolium (Underw.) Gilbert. Maxon. 



SMALL, John K., The Habitats of Polypodium polypodioides. 



(Torreya. Vol. III. Sept. 1903. p. 141.) 



In the southern United States P. polypodioides occurs from sea- 

 level to a maximum of nearly 4000 ft. in the Blue Ridge. Extended 

 observations by the author indicate that the plant is confined to trees 

 only where rocks are lacking, — that is, chiefly along the coastal piain. 

 Above 1000 ft. it rarely if ever grows upon trees.

Vol. III. October 1903. p. 145—150.) 



A tabular view of the genera of pteridophyta recognized by 

 Linnaeus and of the number and geographical distribution of species 

 is followed by an account of the unnatural association of widely differing 

 types under generic names now employed in a very restricted sense. 

 The genus Osmil nda of Linnaeus contained representatives of 9 genera 

 distributed among 4 now universally accepted families, viz. : Ophioglos- 

 saceae, Schizaeaceae, Osmundaceae, Polypodiaceae ; and a similar con- 

 dition prevajls among other genera, notably Acrostichum and Polypo- 

 dium. Of the 17 genera recognized by Linnaeus only 4 as outlined 

 coincide exactly with present usage; these are: Equisetnm, Onoclea, 

 Blechmim and Adiantum. The great majority of Linnaeus' descrip- 

 tions of pteridophyta were compiled from cited descriptions and plates 

 which, as a rule, are of far greater worth and service in interpreting the 

 Linnaean names than are the fragmentary and generally unsatisfactory 

 specimens preserved in the Linnaean herbarium.
