40. P. ANGUSTATA PcWt. 



Hjpogenous; spots pallid or none; sori oblong or linear, some- 

 times regularly arranged at equal intervals in long parallel lines, 

 narrow, surrouncled by the ruptured epidermis, black; spores nar- 

 row, oblong-clavate or elongated, septate above the middle, strongly 

 constricted, having the lower cell more narrow than the upper and 

 cylindrical or slightly tapering downwards, .0018'-.0024' long, 

 .0006' broad; peduncle colored, thick, ver}^ short. 



Leaves ofScirpus Eriophorum and S. sylvaticicm. West Albany 

 and Watkins. September. 



The long narrow spore and very short peduncle, which is seldom 

 more than one-fourlh the length- of the spore, distinguish this 

 species. The lower cell is sometimes scarcely broader than the 

 peduncle. 



It will be seen that eight of the foregoing species inhabit Com- 

 posita3 ; four, Hosacese ; four, Cyperacese ; four, Graminese ; three, 

 Umbelliferse ; two, Rauunculacese ; and one each, BerberidaceoB, 

 Yiolace<^, Caryophyllaceje, Portulacaceae, Geraniacese, Polyga- 

 laceae, Grossulacese, Saxifragaceee, Onagracese, Cornacete, Pubiaceae, 

 Labiatse, Convolvulacese, Polygonacese and Liliacese. All except 

 two, P. pulchella and P. Prunorum^ inhabit herbaceous plants. 

 The two exceptional species are very rare. The former occurs on 

 a small shrub, and our specimens of the latter were found on 

 3'oung seedling plants but a few inches high. 



In closing this report, I desire to express my thanks to those 

 botanists whose names appear in the preceding pages, for their kind 

 and hearty cooperation in the investigation of our flora and for their 

 generous contributions of specimens. A continuance of their aid is 

 earnestly solicited. 



When no name is added to the station or stations herein given, 

 the plant has been found therein by the writer. Dates signify the 

 time w^hen the specimens were collected. 



Eespectfully submitted.
