Science, Manila) 



The last paper under this title was published in 1915,- 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, Ilocahia, of the Cucurhitaceae, 

 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 diversifolia 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.
