foliis ovatis repando-angulatis serratis glabris,” had, however, 
appeared in 1737 in Hortus Cliffortianus. In both works a species: 
of Plukenet (Phyt. Bot. fl. 46. f. g) and a species of Miller (Cat.. 
Pl. Hort. Angl. p/. 737. f. 7) were referred by Linnaeus to his 
Crataegus coccinea. Plukenet’s plant is preserved in the British 
Museum. It belongs to the mollis group, but the specimen is so- 
meager that I have been unable to identify it. Miller’s figure 
perhaps represents a species of the mo/lis group, but it is certainly 
not the same plant as the one figured by Plukenet, and I cannot 
identify it. The only representative of Crataegus coccinea in Lin- 
naeus’s herbarium, and so labeled by him, is an entirely different 
plant from either of those represented in Plukenet’s or Miller’s. 
figures which Linnaeus had referred to his species. Morever,. 
the specimen is not glabrous but villous on the leaves, corymb,. 
and young branches, and the leaves can hardly be described as 

‘‘ repando-angulatis serratis.” The Linnaean specimen is not dated,. 
and it is therefore possible that it was not from this specimen 
but from Plunkenet’s or Miller’s figure that Linnaeus drew his des- 
cription of Crataegus coccinea. There seems in this case, there- 
fore, but one of two methods to follow in considering this name; 
either the specimen in Linnaeus’s herbarium must be ignored, 
and the name dropped entirely because it was given to a species 
founded on two distinct plants, neither of which can be satisfac- 
torily determined; or the specimen in the Linnaean herbarium 
labeled Crataegus coccinea by Linnaeus himself must be accepted 
as the type of this species. In view of the fact that the name 
Crataegus coccinea is one of the best known of the names which 
have been applied to American species of the genus, and as the 
plant labeled Crataegus coccinea by Linnaeus is now known to be 
a common and widely distributed species in the north Atlantic 
coast region, it is perhaps best to consider the specimen in the 
Linnaean Herbarium as the type of Crataegus coccinea, which can 
be described as follows: 
Crataegus coccinea Linnaeus.—Leaves elliptical or on vigor- 
ous shoots mostly semiorbicular, acute or acuminate, divided 
above the middle into numerous acute coarsely glandular-serrate
