ANOTHER DAVENPORT FERN HERBARIUM. 
C. A. WEATHERBY. 
PROBABLY most fern students in America know that the Davenport 
Fern Herbarium is the property of the Massachusetts Horticultural 
Society and is kept in their building in Boston. It consists of speci- 
mens of the ferns known, at the time when it was formed, to occur in 
North America north of Mexico, carefully selected, where selection 
was possible, to show the characteristics and range of variation of 
each species, with a few extra-limital specimens for comparison. 
Its extent is still indicated with a fair degree of accuracy by the Cata- 
logue of 1879 and the supplement thereto of 1883, though after the 
latter date Davenport added occasional sheets of newly discovered 
species or of old ones whose representation he thought inadequate. 
It contains the types of the following species and varieties:—A spidium 
simulatum, Cheilanthes fibrillosa, C. Parishii, C. Pringlei, C. villosa, 
C. viscida, Cystopteris fragilis, var. laciniata, Notholaena Grayi, N. 
Schaffneri, var. mexicana, and Pellaea Wrightiana, var. compacta. 
Critical notes by Davenport himself and letters from Asa Gray, J. 
G. Baker, and D. C. Eaton are now and then pasted into the folders 
which contain the specimens. Altogether, the collection is of more 
than ordinary interest. 
But Davenport's herbarium-making was not confined within the 
limits set for this collection. Almost up to the time of his death in 
1907, he continued to acquire specimens from many parts of the world. 
The resultant collection remained in the possession of his family until 
December, 1922, when it was given to the Gray Herbarium by his 
daughter, Miss Mary Elizabeth Davenport. As there received, it 
numbered about 4500 sheets, of which perhaps 150 were flowering 
plants, mosses, and algae, the remainder ferns. Nearly all of them 
were unmounted, and they had apparently never been fully organized.
