CXLVIII. PANDANE^ (wRIGHT). 



[^Faiidaiius. 



pollen often tubercled. Female flowers densely crowded. Staminodes 

 generally absent. Carpels 1 -celled, solitary or united into phalanges, 

 flat, convex or pyramidal, obtuse, umbonate or rostrate, usually angular ; 

 stigmas reniform or horse-shoe-shaped, rarely forked ; ovule solitary, 

 broadly laterally affixed. Drupes densely congested, but scarcely con- 

 nate, into globose, elliptic or ovoid groups {syncarps) ; pericarp thin, the 

 upper part sometimes deciduous ; mesocarp fibrous and sometimes also 

 fleshy ; endocarp bony, 1- to many-celled. Seed ovoid or fusiform ; 

 albumen oily ; embryo basal, very small. — Trees or shrubs. Stem erect, 

 rarely prostrate, annulate, much forked, rarely simple, bearing thick 

 aerial roots. Leaves linear, acute, usually spiny on the margins and 

 underside of the midrib, sessile, sheathing at the base. Male spadices 

 spicate, female terminal, spicate, racemose or solitary, sometimes pendu- 

 lous ; spathes white or coloured. 



Species about 150, throughout the tropics of the Old World, and extending into 

 Northern India, Queensland and New South Wales. 



Many of the species have been described from imperfect material, and are 

 accordingly difficult to classify.
