112 pittier: new genus of mulberry family 



that the first of these is really a fern, and that the last is at any 

 rate not a true Ficophyllum. The Quercophyllum could possibly 

 be Dictyophyllum, a fern. Thus the angiospermous flora of 

 the Fuson is not beyond suspicion, and apparently the beds 

 may be regarded as somewhat older than the Patapsco. It 

 would be possible to regard the Colorado material as contempo- 

 raneous with the Fuson, or somewhat older, but apparently 

 younger than the Kootanie. 



A note may be added concerning Weichselia reticulata (Stokes 

 & Webb) Ward, reported from the Fuson. Seward 7 gives a 

 detailed drawing of the venation of a specimen from Bernissart, 

 Belgium, and it must be said that this is rather strikingly differ- 

 ent from the venation of the pinnules of the Black Hills plant, 

 as shown in Ward's report. It may be, therefore, that our 

 Lower Cretaceous plant is a distinct species. Seward remarks 

 on the absence of fructification in specimens of Weichselia, 

 and suggests that it may not be a true fern, but Zeiller, 8 re- 

 cording specimens from Peru, states that he found fertile fronds, 

 and that the plant is really a fern, perhaps a member of the 

 Marattiaceae. 



BOTANY. — Inophloeum, a new genus of the mulherry family. 

 Henry Pittier, Bureau of Plant Industry. 



Under the name Olmedia? armata Miquel described briefly 

 in 1854 a remarkable moraceous tree, a meager specimen of 

 which was collected by Seemann on the Cupica River in the 

 Colombian Darien. That he remained in doubt as to the proper 

 place of the species is shown by the question mark following the 

 generic name and by the following remark preceding the de- 

 scription: "Valdopere dolendum, stirpem admodum memorabilem 

 ex unico parvulo ramulo vix certe definiendam nee apte de- 

 scribendam esse." 1 



In the course of the botanical survey of Panama I have col- 

 lected specimens of the same tree at several places in the forests 

 to the east of the Canal, and from a specimen of the bark in the
