282 PITTONIA. 
these old composites it must never be forgotten that, in 
all the old synantherology, what we of today call a capi- 
tulum was called a flower; that our involucre of the com- 
posite was always with them a calyx. It is, therefore, 
contrary to all reason to suppose that Gronovius had any 
monocephalous stem in mind, or before his eye, when he 
wrote tbe descriptive phrase caule capitato; and I am obliged 
to think that, under Clayton's n. 287 there must have been 
specimens of some other Antennaria besides that one which 
is said to represent A. solitaria, and such as exhibited, along 
with the glabrous upper face of the leaves, a capitate cluster 
of heads; or plainly, my A. arnoglossa. 
As for specimens existing in the Linnean Herbarium, it 
must be remarked that such must first be shown to have 
been type specimens, before any forceful inferences can be 
drawn from them. It is well known to many of the disap- 
pointed people who have tried, during the last century, to 
find in that herbarium evidence upon the identity of species, 
that the collection was continually being augmented during 
the quarter-century of Linnæus’ life after the publication of 
the Species Plantarum; that he again and again put into it 
specimens which he supposed to represent species which he 
had published on purely bibliographie data. 
That those Antennaria specimens are type specimens no 
one knows. That they are the identical ones which Lin- 
nius said he had seen, no one knows. May be they are; 
we may even say probably they are; but still they are 
hypothetical evidence in the ease, and therefore no real 
evidence at all. Nor is it, in my view, of any importance 
that they should be verified, if they can be, as type speci- 
mens. Linnzus' Species Plantarum is a classic piece of 
bibliography, and only partially, and often then very 
ambiguously, of the nature of a nineteenth century descrip-
