NOTES ON PHILIPPINE PALMS, II. 62o 



bristly; spikelets short. 3 to 4 cm long, rather broad, with a zigzag-sinuous 

 axis, and with only 4 or 5 alternate flowers, or pairs of flowers, <m each 

 side; spathes broad, concave, embracing the involucre, and produced at 



one side into a triangular point ; involucrophore concave, quite sessile, 

 attached laterally to the base of the spathel above its own : involucre 

 shallowly, and. often, asymmetrically cupular, usually bidentate at one 

 side. Female flowers ovate a (i mm long, usually in pairs at each spathel 

 in the lower part of the spikelets ; in this case they are not accompanied by 

 a neutral flower; near the end of the spikelets the female flowers are 

 solitary, and the involucre bears a very depressed, lunate, sharply defined 

 areola for the reception of the neuter flower. Fruit, when still very 

 young, ventricose in the middle, narrowed at both ends, stoutly beaked 

 and terminated by three, small, recurved stigmas. Scales in fifteen lon- 

 gitudinal series, not channelled along the middle, of a straw-yellow color 

 in the postieous part and with a broad black marginal line, apices squar- 



iose. slightly produced, and erosely-ciliate. Seed Fruiting 



perianth eampanulato, narrowing to a rather acute base; the calyx split 

 down past the middle into three broadly ovate lobes; the corolla barely 

 longer than the calyx.

A very singular species of the group of ('. palustris, related to ('. Jenningsianus, 

 hut quite distinct by its larger fruit and especially by its geminate flowers in the 

 lower part of the spikelets. N. v. (iri<<i<la.
