Family description included here as various horticultural forms of the 

 rose (genus Rosa) are cultivated in Manila; however, it has been found 

 to be impossible to classify these with any degree of accuracy, hence 

 no descriptions aire included. A single indigenous species of the genus 

 occurs in the Mountain Province, Luzon (Rosa multiflora Thunb.). Of 

 other representatives of the family occasionally found in. Manila, the 

 strawberry, Sp. fresa (Fragaria veaca L.), is sometimes cultivated. I have 

 seen a single plant of one species of raspberry (Rubu8 rosaefoliuB Sm.), 

 cultivated, but as it persisted far a few months only it has not been in- 

 cluded; the species is widely distributed in the Philippines.
