TYPUS: Oahu, Manoa and Wailupe, William 
Hillehrand & J. M. Lydgate (BISH), (st. If. fl.). 
SPECIMENS EXAMINED: Oahu, Wailupe, Ex 
Museo botanico Berolinensi, ex coll. Hillehr. 
(/. F. Rock 17,062), (BISH). 
DISCUSSION: The data on these specimens 
need interpreting. The specimen to which 
Professor J. F. Rock added in his own hand 
his collection number 17,062 on the label of 
the College of Hawaii Herbarium, also has a 
printed label with ’’Ex Museo botanico 
Berolinensi” and in Rock’s hand, "Isoden- 
dron laurifolium Gray, Oahu, Wailupe.” On 
a visit to the Berlin herbarium in the spring 
of 1914, Rock was given clastotypes of nearly 
all of Hillebrand’s new Hawaiian species, that 
is, of all that were large enough to divide. He 
also received fragments or duplicates of some 
of Hillebrand’s other collections. These 
precious specimens came to the College of 
Hawaii; later they were transferred and are 
now in the B. P, Bishop Museum. This is the 
history of this one and many similar sheets. 
In this case it consists of a single detached 
good leaf, and two minute branch tips and 
two broken, tiny, depauperate leaves. 
The second sheet, the one chosen as the 
type, has a different story. While living on 
Oahu, Dr. Hillebrand inspired several men to 
be his companions in exploring, helpers, or 
independent collectors. One such, when a 
young man, was the Reverend John M. Lyd- 
gate. He made many valuable contributions 
to Hillebrand’s herbarium. Later, from Ger- 
many, Hillebrand sent to Lydgate named 
duplicates, not only of the ones that Lydgate 
collected, but of many others. These were 
labeled on loose tickets in Hillebrand’s hand, 
giving the name and the locality. The writer
