PANDANACEAE 



PAN DAN us Linnaeus f. 

 PANDANUS APICULATUS sp. nov. § Rykia. 



Arbor, circiter 5 m alta, ramulis 2.5 ad 3 cm diametro; foliis 

 circiter 1 m longis et 5.5 cm latis, in siccitate subflaccidis, sur- 

 sum angustatis, apice tenuiter acuminatis, inter nervis transver- 

 salibus distincte reticulatis ; inf ructescentiis lateralibus, 10 ad 15 

 cm longis, syncarpiis spicatim dispositis, plerumque 10, confertis, 

 ovoideis ad globosis, 15 cm diametro ; drupis numerosis, confertis, 

 cylindricis vel oblongis, 1-locellatis, 6 ad 7 mm longis, 2 ad 2.5 

 mm diametro, apice rotundatis et acute apiculatis, stylis circiter 

 1 mm longis. 



A tree, about 5 m high, the ultimate branches 2.5 to 3 cm in 

 diameter. Leaves about 1 m long and 5.5 cm wide, somewhat 

 flaccid when dry, the margins armed with rather conspicuous 

 teeth, the midrib beneath near the base v/ith retrorse teeth and 

 toward the apex with antrorse teeth, the 2 lateral nerves 

 sometimes with a few scattered teeth on the upper surface near 

 the apex, the blade more or less narrowed to the distinctly and 

 rather slenderly acuminate apex, distinctly transversely retic- 

 ulate between the numerous secondary nerves. Infructescences 

 lateral, from the base of the apical tufts of leaves, 10 to 15 cm 

 long, the syncarps ovoid to globose, sessile, about 1.5 cm in 

 diameter, usually about 10 on each infructescence, the peduncles 

 closely covered in the lower half with numerous, imbricate, 

 spirally arranged, oblong bracts, which are usually about 4 cm 

 in length. Drupes numerous, crowded, red, cylindric or oblong 

 or sometimes narrowed below, 1-celled, 6 to 7 mm long, 2 to 2.5 

 mm in diameter, the apical 1.5 to 2 mm free, rounded, terminated 

 by the indurated, slightly upward-curved, usually acute style, 

 which is usually about 1 mm in length.

 casio, April 25, 1919, on ridges, altitude about 690 meters, at 

 the iron deposit on the northeast coast. 



A rather remarkable species on account of its lateral infruc- 

 tescences and its multibracteate peduncles. It is manifestly 

 allied to Pandanus multibracteatus Merr., but has much wider 

 leaves and differs essentially in its fruit characters, the drupes 

 being much smaller and not prolonged into slender, elongated 

 tips, as in the latter species. 



PANDANUS DINAGATENSIS sp. nov. § Rykia. 



Frutex parvus, ramulis circiter 3 cm diametro; foliis usque 

 ad 1.75 m longis, circiter 6.5 cm latis, subcoriaceis, sursum
