 Hieron. Papuasia is one of the richest regions in the world in ferns. The geographical fern 

 region of Papuasia extends to the neighboring islands in all directions, and the limits are 

 given. A table is given of the number of species in each genus common to Papuasia and each 

 of the surrounding groups of islands as well as countries more distant. Trichomanes is espec- 

 ially well developed. Dryopteris is also highly developed with 112 species. Polypodium is 

 the largest genus with 168 species. Aspidium and Polystichum are poorly represented. The 

 Pterideae are little developed. Azolla, Marsilea, Salvinia, and Pihilaria have as yet not 

 been found. Botrychium is not known, though Ophioglossum is moderately represented. 

 Selaginella is represented by 58 species. — K. M. Wiegand. 



498. Brause, G. tJber die von C. R. W. K. van Alderwerelt van Rosenburgh neu auf 

 gestellte Gattung Thysanobotrya. [On van Alderwerelt van Rosenburgh's new genus Thysano- 

 botrya.] Hedwigia 61: 401. 1920.— Gepp described a new fern from Dutch New Guinea as 

 Polybotrya arfakensis. Van Rosenburgh separated this under a new generic name as 

 Thysanobotrya arfakensis Gepp) v.A.v.R. The present author finds that the original 

 description and figures correspond to Alsophila biformis Ros. He considers Alsophila the 

 proper genus for this plant and sees no reason for the creation of a separate genus Thysano- 

 botrya. — K. M, Wiegand. 



499. Hierontmus, G. tJber Cheilanthopsis Hieron., eine neue Farngattung. [Cheilan- 

 thopsis, a new genus of ferns.] Notizbl. Bot. Gart. Berlin 7: 406-409. 1920. — The genus dif- 

 fers from Cheilanthes in its dorsiventral spores; from Hypolepis, to which it is closely related 

 in its ascending rhizome and fascicled leaves. Although based on Cheilanthes straminea 

 Brause, no transfer of that species to the new genus is made. — H. A. Gleason.
