62. PITTOSPORACEAE (PITCHSEED OR MAMALIS FAMILY) 
Trees or shrubs, mostly glabrous. Leaves alternate, simple, entire, 
exstipulate. Flowers 5-merous, perfect, in terminal or axillary corymbose 
cymes, rarely fascicled. Sepals free or connate below, imbricate. Petals 
narrow, hypogynous, imbricate, their claws usually connate. Staments 5, 
opposite-the sepals. Ovary incompletely 2- or 3-celled, sessile or shortly 
stalked; ovules 2 to many on each placenta. Fruit a fleshy, coriaceous, or 
woody, 1-celled, 2- or 8-valved capsule, the valves bearing placentae in 
the middle, the seeds few to many, embedded in a resinous or oily pulp. 
Genera 9, species about 110, chiefly Australian, 1 genus in the Philip- 
pines. 
1. PITTOSPORUM Banks 
Characters of the Family as given above. (Greek “pitch” and “seed.’’) 
Species about 75, India to Australia and Polynesia, about 8 in the Phil- 
ippines. 
1. P. pentandrum (Blanco) Merr. Mamalis (Tag.). 
‘A small tree 4 to 8 m high, glabrous except the inflorescence. -Leaves 
lanceolate, gradually narrowed at both ends, rather slenderly acuminate, 
6 to 15 cm long. Panicles 5 to 8 cm long, rusty-pubescent, rather dense, 
many-flowered. Flowers white, fragrant, about 6 mm long. Fruit sub- 
globose when fresh, pale-yellow, 6 to 8 mm in diameter, resinous inside and 
with a strong, somewhat turpentine-like odor. Seeds brown, flattened, 
about 8 in each capsule. 
Cementerio del Norte, fl. June-July; widely distributed in the Philip- 
pines. Endemic. 
63. ROSACEAE (ROSE FAMILY) 
Herbs, shrubs, or trees with alternate, simple or compound leaves, 
usually stipulate. Flowers perfect, regular, rarely irregular. Calyx-tube 
free or adnate to the ovary, the limb 5-lobed. Petals 5, deciduous, imbricate. 
Disk lining the calyx-tube or forming a ring at its base. Stamens pe- 
rigynous, numerous, rarely 5 or 10, in one or many series. Ovary of 
one or more free or connate carpels, with free or connate, basal, lateral, 
or terminal styles; ovules 1 or more in each cell. Fruit drupaceous, 
baccate, or of many achenes on a dry or fleshy receptacle, rarely capsular. 
Genera 100, species about 1,500, in all parts of the world, but chiefly 
in temperate regions, 6 genera and 30 species in the Philippines. 
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 are 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 (F'ragaria vesca L.), is sometimes cultivated. I have 
seen a single plant of one species of raspberry (Rubus rosaefolius Sm.), 
cultivated, but as it persisted for a few months only it has not been in- 
cluded; the species is widely distributed in the Philippines.
