Report of the Botanist. 91 



brown at the base, "deorsiim fnscescente," although closely adher- 

 ing bits of bark sometimes give it such an appearance, the pores 

 are not of an orange color, " dilute aurantiacis," and the pileus is 

 not smooth then scaly, "Isevi dein squamoso," though it is either 

 smooth or scaly. The pores are generally decurrent, yet this 

 prominent character is not mentioned in the description of Fries. 

 In view of these discrepancies it seems almost certain that our 

 plant ought to be regarded as a distinct species, but, in view of its 

 variable character, I hesitate to separate it as such until I shall 

 have had the opportunity of comparing it with authenticated 

 European specimens of P. Boucheamcs. 



Gymnosporangium clavipes C. <& P. 



The protospores germinate at each end, the pedicel separating 

 from the base about the time the filament protrudes from the lower 

 or basal cell of the protospore. In Podisoma Juniperi the pro- 

 tospores germinate at the septum.

Leaves of Clematis Virginiana. Poughkeepsie. Gerard. 



Id the preceding pages, when no name is added to the station or 

 stations, the plant has been found therein by the writer. Dates sig- 

 nify the time of collecting the specimens, and therefore indicate to 

 some extent the time of tlie occurrence of the plant. The single and 

 double accent marks placed at the right of figures denote respectively 

 inclies and twelfths ot" an inch. 



My warmest thanks are due to those Botanists who have kindly 

 aided me by their generous contributions of specimens. 



Most respectfully submitted.
