tant herbaria in the country and was always placed at the service of 
monographers who wished to study it. It not only represented 
the forty-five years of collecting of its founder, but was increased 
through extensive exchanges and purchases. For years Mr. Canby 
bought every collection offered for sale. It was largely through the 
efforts of a few men, one of whom was Mr. Canby, that Parry and 
Palmer made their trip to San Luis Potosi, Mexico, in 1877, which 
yielded such an astonishing number of new plants. He also aided Mr. 
Pringle in his early struggles in Mexico. 
In 1893 his herbarium numbered some 30,000 specimens, and was 
about this time sold to the College of Pharmacy of New York city, 
where it now remains. He had no sooner disposed of his herbarium 
than he began, with all the enthusiasm of a young man, to build up a 
new one, giving it to the Natural History Society of Delaware at 
Wilmington. This herbarium contains about 15,000 species at the 
present time. Although Mr. Canby was a very keen and able botanist, 
he rarely described new plants, usually contenting himself with point- 
ing out differences and permitting specialists to publish the results of 
his discoveries. 
Quite a number of plants have been named in his honor. The 
genus Canbya, though named by Dr. C. C. Parry, was described by 
Dr. Asa Gray in the Proceedings of the American Academy in 1876. 
Among the species I recall the following: Angelica Canbyi C. & R., 
Crataegus Canbyi Sargent, Hydrocotyle Canbyi C. & R., Ligusticum 
Canbyi C. & R., Lobelia Canbyi Gray, Pachystima Canbyi Gray, Pedicu- 
laris Canbyi Gray, Peucedanum Canbyt C. & R. 
Although Mr. Canby never wrote any extensive work, he was an 
occasional contributor to botanical journals, and some eleven articles 
in this journal were furnished by him. Mention should 
his very valuable contributions to the study of insectivo 
especially in connection with Dionaea and Darlingtonia. 
made free use of his observations and refers to his work in high terms. 
In his writings he always referred to Mr. Canby as “Dr. Canby,” 
although I belive he never received a degree of any kind. He once 
told the writer that one of our American colleges had offered him the 
degree of Ph.D., but he declined it—J. N. Rose, U. 5. National
