The last paper under this title was published in 1915, 2 the 
present contribution being essentially similar to the preceding 
ones of the series. Seventy-two species in thirty-four families 
are described as new, the groups considered being those that 
for the most part present comparatively few novelties in cur- 
rent collections. One new genus, Ilocania, of the Cucurbitaceae, 
is described. Eight species previously described from extra- 
Philippine material are for the first time credited to the Archi- 
pelago, representatives of these having appeared in our current 
collections ; among these the genus Zippelia is new to the Archi- 
pelago. A noteworthy species, presenting another striking 
case of Philippine-Australian distribution is the rare and very 
characteristic Ipomoea diversifolict R. Br., which has definitely 
been reported only from the small islands in the Gulf of Car- 
pentaria, but which now appears in our collections from north- 
western Luzon. Sida longistipula Merr., described below, a 
very characteristic and strongly marked species, finds its alliance 
with a few Australian species rather than with the Asiatic 
representatives of the genus. Vitex celebica Koord. adds 
another species to the already long list of those known only 
from the Philippines and Celebes.
