In an article in the Annals of Botany for November, 1887, B. 
L. Robinson reviews the structure and history of Taphrina, and 
compiles an annotated catalogue of the North American species, 
so far as known. According to this article there are eight well- 
known species, with several others which are less perfectly known, 
as follows :— 
Taphrina pruni Tul., on the fruit of Prunus domestica L., form- 
ing “the so-called ‘plum pockets? ” The Taphrina on Prunus 
maritima Wang., P. virginiana L., and P. serotina Eber., is con- 
sidered to be “ probably identical.” 
T. deformans Tul., causing the “peach curl” of the leaves of 
the peach tree. A Taphrina, probably the same as this, has been 
found several times in Massachusetts deforming the leaves and 
branchlets of Prunus serotina Eber.” 
T. purpurascens Robinson ( Ascomyces deformans Berk. var. purpu- 
rescens Ellis and Everhart). On leaves of Rhus copallina L., caus- 
ing them to become dark purple in color, wrinkled, limp, an 
t 
ndent. 
T. potentillæ Johnson, on leaves of Potentilla canadensis L. h 
T. flava Farlow, on leaves of Betula alba, var. populifolia Spach, 
and also on Betula papyracea Ait. “This species must be care- 
fully distinguished from the more recent and very different Fvoas- 
vus of Sadebeck.” ” 
T. alnitorqua Tul., “ on bracts of the fertile catkins of the ey 
1. aurea Fries. “The only form of this species yet found 1 
America, attacks the fertile catkins of poplar trees (Populus gran- 
didentata Michx.). : i 
| coerulescens Tul., on the leaves of various species of 0288, 
producing grayish or bluish spots.—Charles E. Bessey.
