Maxon, from Jamaica, which is the plant wrongly caWed D. aculeata 

 by Jenman, O. Wrightiana Maxon, from Cuba and the Isle of Pines, 

 related to the true O. aculeata of eastern Cuba, Hispaniola, and 

 Port Rico (of which DavalUa dumosa Sw. is a true synonym), O. 

 colombiana Maxon, from Colombia, Lehmann XXXIV, hitherto 

 confused with O. Schlechtendahlü. 



4) Notes upon Bomnieria and related genera. Includes 

 descriptions of the following new species: Bommeria subpaleacea 

 Maxon, from Puebla, Mexico, Purpus 4025, and Hemionitis Otonis 

 Maxon, from Costa Rica, Oton Jimenez 333. The generic name 

 Pityrogramma Link, 1833, is shown to apply to the genus recently 

 known as Ceropteris Link, 1841, and the following new "combina- 

 tions" are published: Pityrogramma triangularis {Gymnogramma 

 trianguläre Kaulf.), P. viscosa {G. triangularis viscosa D. C. Eaton), 

 P. tartarea {Acrostichutn tartareum Cav.), P. peruviana {G. peruviana 

 Desv.), P triangulata {G. triangulata Jenman), P. sulphurea {A. sul- 

 phureum Sw.), and P.f er ruginea{G. ferruginea Kunze). The Mexican 

 plant described originally as Gymnogramma subcordata Eaton and 

 Davenport is regarded as an American representative of the other- 

 wise exclusively Old World genus Coniogramme , C. subcordata Maxon. 



5) New species of Lycopodium. The following are described 

 as new: Lycopodium brachiatum Maxon, from Cocos Island, L. chi- 

 ricanum Maxon, from Chiriqui Volcano, Panama, L. guatetnalense 

 Maxon, from Alta Verapaz, Guatemala, L. lancifolium Maxon , (rom 

 western Panama, and L. tuhulosum Maxon, from Costa Rica.

 rula Maxon, based upon von Tuerckheim 3056, related to C.tenera 

 (J. Smith) Griseb. - Maxon.

 of the Hawaiian Islands, II. (Bull. Torrey Bot. Club. XXXIX.

In the present instalment the first 18 genera of the family 

 Polypodiaceae , as represented in the Hawaiian Islands, are treated. 

 One new species {Dryopteris parvula W. J. Robinson) is described. 

 The following new "combinations" and new names are published: 

 Hypolepis ßaccida {Phegopteris punctata ßaccida Hilleb.) , Diellia cen- 

 tifolia {Lindsaya centifolia Hilleb.), D. laciniata [Lindsaya laciniata 

 Hilleb.), D. Mannii [Microlepia Mannii D. C. Eaton), Filix Douglasii 

 {Cystopteris Douglasii Hook.), Ceropteris ochracea {Gymnogramma 

 ochracea Presl.), Dryopteris paleacea {Aspidium paleaceum Sw.), D. 

 fuscoatra {Aspidium Filix mas fuscoatrum Hilleb.), D. hawaiiensis 

 {Aspidium hawaiiense Hilleb.), D. rubiformis, nom. nov. {Polypodium

Stoland, O. O., The abortive spike of Botrychium. (Bot. 

 Gazette. LIV. p. 525-531. fig. 1—21. Dec, 1912.) 



As the result of an investigation undertaken to determine the 

 origin and nature of the vascular suppl}'" of the abortive spike in 

 Botrychium virginianum the following conclusions were reached by 

 the author: 



1) The leaf trace ofthe petiole bearing the abortive spike consists 

 of several bundles instead of two bundles as usually found in the 

 petiole bearing the fertile spike.
