344 A FLORA OF MANILA 



capitate. Fruit large, rather hard, depressed-globose, many-seeded, sup- 

 ported by the calyx-tube, the calyx-lobes persistent, spreading. (In honor 

 of P. Sonnerat, a Frejich naturalist and explorer.) 



Species about 6 along the seashore in the Indo-Malayan region, 2 in 

 the Philippines. 



Leaves obovate, rounded. 1. S. pagatpat 



Leaves oblong to elliptic-oblong, somewhat pointed 2. S. caaeolaris 



1. S. pagatpat Blanco. Pagatpat (Tag.). 



A shrub or tree reaching a height of 20 m or less. Leaves very thick, 

 leathery, obovate, rounded, 6 to 10 cm long, often nearly as wide as 

 long. Calyx green, leathery, 3 to 4 cm long, the seg:ments 6 to 9, lan- 

 ceolate to oblong-lanceolate, acuminate, equaling or long'er than the tube. 

 Petals white, linear, early deciduous, nearly as long as the calyx- 

 segments (sometimes wanting). Stamens very numerous. Fruit hard, 

 depressed-globose, 3 to 4 cm in diameter, surrounded nearly to the middle 

 by the calyx-tube, the persistent lobes spreading. 



Along tidal estuaries, il. most of the year; throughout the Philippines 

 along the seashore. Endemic (?), or perhaps not specifically distinct from 

 the widely distributed Indo-Malayan Sonneratia alba Sm. 



2. S. caseolarls L. Engl. (S. acida L. f.) Pagatpat (Tag.). 



Similar to the preceding, but the leaves oblong to elliptic-oblong, some- 

 what pointed, rarely obtuse, 4 to 10 cm long, 2 to 4 cm wide, tapering 

 to the -base. Flowers solitary, the calyx green, 2.5 to 3 cm long, the 

 segments 6, longer than the tube. Petals 6, linear, pink or white, about as 

 long as the calyx-segments. Fruit about as in the preceding species. (Fl. 

 Filip. pi. 175, S. pagatpat.) 



Along tidal estuaries, but less abundant in the Philippines than the 

 preceding. India to Majaya. 



99. PUNICACEAE (Pomegranate or Granada Family) 



Shrubs or small trees, the branches often spiny, the young ones 4- 

 angled. Leaves opposite, subopposite, or clustered, entire. Flowers soli- 

 tary or few at the ends of the branches, large, perfect, regular. Calyx- 

 tube funnel-shaped, adnate to the ovary below, enlarged above the ovary, 

 the lobes 5 to 7, persistent in fruit. Petals as many as the calyx-lobes, 

 alternate with them, wrinkled. Stamens very numerous, inserted around 

 the mouth of the calyx tube, bent inward in bud. Ovary united with 

 the calyx-tube, many-celled, the cells arranged in 1 to 3 -whorls. Style 

 slender, elongated; stigma capitate; ovules many in each cell, some 

 axillary, some parietal. Fruit a globose berry with a thick pericarp, 

 crowned by the calyx-segments. Seeds, angular, very numerous. 



A single genus with 2 species, 1 introduced in the Philippines.

 1. P. GRANATUM L. Granada (Sp.) ; Pomegranate. 



A shrub 2 to 3 m high, the branchlets slender, 4-angled, often ter- 

 mmating with a short spine. Leaves oblong-lanceolate to oblong-elliptic, 

 4 to 6 cm long, short-petioled, acute or obtuse, narrowed at both ends.
