NOTES ON PHILIPPINE PALMS, EL 619 



apex, where they abruptly and symmetrically taper Into a long filamentose 

 tip; the margins minutely spinulous from the middle upward, the 

 Bpinulea becoming closer near the apex: transverse veinlets very sharp 

 and prominent on the upper surface, much less visible underneath: the 

 mid-costa almost equally prominent on both surfaces, smooth and ac- 

 companied on each side by several unequal, slender, parallel, secondary 

 nerves, of which one, lying nearer to the margin, is often stronger than 

 the others, especially near the base, where the leaflets may he called 

 subtricostulate: but these side costae evanesce upward. Male spadix 

 apparently short, with several approximate short branches: each branch 

 being subtended by a primary spathe and bearing 6 to 8 approximate 

 spikelets; the primary spathes are covered with a tenuous, rusty, soft 

 indumentum, are marcescent and much lacerated or split longitudinally, 

 and reduced to several strips and filaments. Male Spikelets when in 

 flower cylindraceous, slender, 5 to 7 cm long, 10 to 11 mm broad, borne 

 on a verv short pedicel, which is embraced by a short and broad, mem- 

 branaceous, braeteiform secondary spathe: the spathes are not connate by 

 their margins and they do not form an annular involucre, as is usual 

 with the other species, but are individually distinct, braeteiform, concave, 

 very broad, acute, and striate, each bearing two lowers; bracteoles small 

 woolly-rameiitaceous. Male flowers small, slightly longer than the spatho- 

 lets, 4 mm long: calyx split to the base into ;?, linear, thinly mem- 

 branaceous or subhyaline, striate segments; the corolla is slightly longer 

 than the calyx, three-parted nearly to the middle, and tapering below, its 

 segments are short, oblong: stamens united to the corolla as far as the 

 base of the segments; anthers oblong, obtuse.

Tii its leailets being whitish beneath, this species approaches Zalacca Blumeana, 

 Z. edulis, and especially Z. vermieularis, but it differs from these as from all 

 the other Species known to me, in the spathes and the male spikes, which are 

 individually distinct, and are not connate by their margins to form a compound 

 annular spathe.
