2. CASEARIA Jacquin 
Erect unarmed shrubs or small trees, with alternate, distichous, entire 
or toothed leaves. Flowers small, perfect, in axillary clusters, the pedicels 
short, jointed. Calyx deeply 4- or 5-lobed. Petals none. Stamens about 
twice as many as the calyx-lobes, the filaments somewhat united in a tube 
below, alternating with staminodes. Ovary superior, free, 1-celled; ovules 
many. Fruit fleshy, ovoid to ellipsoid, ultimately dehiscent. Seeds angular 
or obovoid, usually with a fleshy aril. (In honor of J. Casearius, a Dutch 
botanist. ) 
Species 120 in the tropics of both hemispheres, about 7 in the Philippines. 
1. C. fuliginosa Blanco. 
A shrub or small tree 2 to 5 m high, nearly glabrous, the branchlets 
often slightly zigzag. Leaves oblong-ovate, 7 to 18 cm long, entire or 
nearly so, often slightly falcate, slightly acuminate, base broad usually 
rounded, often somewhat inequilateral. Flowers small, white, in few to 
many-flowered axillary clusters, 4 to 5 mm diameter, pale-green. Sepals 
5, pubescent externally. Filaments hairy. Fruit ovoid or ellipsoid, 10 
to 12 mm long, red or yellow when mature. Seeds arillate. (FI. Filip.

in the Philippines. Endemic. 
93. PASSIFLORACEAE (PASSION FLOWER FAMILY) 
Usually perennial herbaceous or somewhat woody vines, climbing by 
means of tendrils. Leases alternate, simple, entire or lobed, stipules 
usually present. Flowers axillary, solitary, or in cymes, small to large, 
usually with 3 minute to large bracteoles, regular, perfect or unisexual. 
Calyx tubular at the base, fleshy to thin, 5-lobed. Petals as many as the 
calyx-segments, or none. Corona of one to several rows of slender fila- 
ments, arising from the calyx-tube, rarely none. Stamens 5, the filaments 
united and adherent to the stalk of the ovary. Ovary usually stalked, 
1-celled, many-ovuled, with parietal placentae; styles usually 3. Fruit 
berry-like, fleshy, indehiscent, often large, or capsular and 3-valved. 
Genera 11, species about 400, chiefly tropical, most numerous in tropical 
America, 2 genera and about 7 species in the Philippines.

1. PASSIFLORA Linnaeus

calyx-lobes. Corona of 1 to several rows of numerous, usually filiform 
segments springing from the calyx-tube. Gynophore surrounded at the 
base by a shallow membranaceous cup or basal corona. Anthers 5, dorsi- 
fixed. Ovary 1-celled; styles 3. Fruit fleshy, berry-like, indehiscent, the 
seeds arillate. (Adapted from the Latin flos passionis.)
