72 MERRILL. 
The present paper is based primarily on specimens collected 
by Father Vanoverbergh ; but in a number of cases I have been 
able, with aid of his material, to complete the determinations 
of specimens previously secured by other collectors and which 
for the most part had been determined only to the genus or 
family, or in some cases erroneously identified. From a study 
of his material I have been able to record, in the present paper, 
three genera, Microcarpaea, Trachelospermum, and Teucrium, 
previously unknown from the Archipelago, and two, MicrochJoa 
and Blyxa, which were included by Fathers Villar and Naves in 
the **Novissima Appendix" to the third edition of Blanco's "Flora 
de Filipinas," and whose records have not previously been veri- 
fied. An apparently undescribed genus, Vanoverberghia, has 
been discovered in the collection, and I have been able to reduce 
one genus, CleistoloranthiiSj previously proposed by me, so that 
the number of genera definitely known from the Archipelago 
has been increased by five. As to species originally described 
from extra-Philippine material but previously not definitely 
known from the Archipelago, I have been able to record the 
following eleven: Blyxa octandra Planch., Microchloa setacea 
(L.) Merr., Scleria pergracilis Kunth, Cocculus laurifolius DC, 
Rhynchosia voliibilis Lour., Lysimachia capillipes Hemsl., L. 
deciirrens Forst., Microcm^aea minima (Koenig) Merr., Acro- 
cephahis indicus 0. Ktze, TJtricularia exoleta R. Br., and Cam- 
panumoea truncata Endl. Thirty-one species are described as 
new. I have previously described one new species of Begonia 
from Father Vanoverbergh's material, B, vanoverherghii Merr. 
Dr. C. B. Robinson has indicated two new species of Elatostema, 
E. scapigerum C. B. Rob,, and E, variabile C. B, Rob., in the same 
collection. Several new species of orchids have been described 
by Mr, Ames,^ while additional ones have been indicated for 
future publication. A study of Father Vanoverbergh's material 
has therefore increased our knowledge of the Philippine flora 
by six genera and over sixty species. I have dedicated the new 
genus Vanoverberghia, described below, to its discoverer and 
collector, and as its specific name I have associated with it the 
appellation sepulchrei in honor of the late Father Jules Sepul- 
chre, Father Vanoverbergh's colleague and companion at Bauco, 
and the founder of the mission station at that place. Father 
Vanoverbergh informs me that Father Sepulchre took a lively 
interest in the botanical work and was of much assistance to
