1918] Blake,— Notes on the Clayton Herbarium 67 
The Linnaean Gerardia flava (Sp. ii. 610 (1753))' was a complex 
of the puberulous species, G. flava of authors (as to citations), and 
the glaucous species, G. virginica of authors (as to specimen in Lin- 
naean Herbarium). It has been restricted to the puberulous species 
by practically all authors except Pennell, who has recently referred 
it to the glaucous plant figured as G. quercifolia by Pursh. Under 
these circumstances it seems advisable to continue the practice of 
practically all writers and retain the name in its established applica- 
tion for the puberulous species, designating as type the Clayton speci- 
men (no. 9), cited by Gronovius (p. 74) and now in the British Museum, 
which I have examined. The two names, Gerardia flava and Rhinanthus 
virginicus, of the same date (1753), were first combined by Dr. Pennell 
(Bull. Torr. Club xl. 409 (1913)), who adopted the name virginicus 
(Aureolaria virginica (L.) Pennell). Although this name was unfortu- 
nately applied by Dr. Pennell to the glaucous species, the G. virginica 
of the manuals, it must now be used, under another generic name, for 
the puberulous plant generally called G. flava. 
The oldest name applying to the glaucous species generally known as 
G. virginica, and the only appropriate one it has ever received, ,is 
GERARDIA GLAUCA Eddy, Med. Repos. N. Y. hex. 2. v. 126 (1808). As. 
this work is decidedly rare, it may be well to quote Eddy’s description, 
which occurs in his “Plantae Plandomenses, or a Catalogue of the 
Plants growing spontaneously in the Neighborhood of Plandome, the 
Country Residence of Samuel L. Mitchill. By Caspar Wistar Eddy, 
Student of Medicine,” which is dated from “ New-York, August 28th, 
1807.” . It runs as follows: “Gerardia glauca,* (species nova mihi.) 
Descr. G. foliis inferne lyrato-runcinatis serratis, medio pinnatiffido- 
erratis [sic], et superne lanceolatis serratis; caule glauco, paniculato; 
soribus pedunculatis.” (Footnote.) “*I have also found this plant 
about two miles and a half from New-York, but first observed the 
difference between it and the G. flava of Linnaeus in the summer of 
1805.” 
In his preliminary paper on the genera of the Agalineae (Gerardieae 
of authors), Dr. F. W. Pennell (Bull. Torr. Club xl. 119-130 (1913))
