him in his botanical labors. Father Sepulchre died very sud- 
denly in Bontoe on February 13th, 1912, and was buried in 
the church erected by himself. It is but a very slight acknowl- 
edgement of Father Vanoverbergh's services to Philippine 
botany to fulfill his request and to associate with the genus 
dedicated to him the name of his regretted friend, colleague, and 
companion. 
In the year 1909 I described a new genus of the Loraiithaceae, 
Cleistoloranthus,^ which on reexamination and comparison with 
excellent material representing the same species, secured by 
Father Vanoverbergh, I am now able to reduce to Loranthiis, 
The type of the genus and species proves to have been a spec- 
imen with immature flowers. Cleistoloranthus may still be 
worthy of sectional rank on account of the peculiar appendages 
to the petals, but it can hardly be retained as a distinct genus 
if we follow the limits of genera generally accepted in this 
family. 
The types of the new species indicated in the present paper 
are preserved in the Herbarium of the Bureau of Science, which 
also contains a complete or nearly complete set of all the botan- 
ical material collected in Bontoe by Father Vanoverbergh. He 
has also sent some material to the University of Louvain, Bel- 
gium, and many duplicate orchids have been supplied to Mr, 
Ames. Some duplicate material still remains to be distributed 
by the Bureau of Science. 
Father Vanoverbergh's botanical work in Bontoe was inter- 
rupted in August, 1911 by his transfer to a new station in Union 
Province, but on the death of Father Sepulchre he was reas- 
signed to the Bauco station, where he plans to continue his 
botanical explorations.
