plants only are variegated and possibly also in gardens the very 
similar Pinanga disticha may also go under the name of P. ma- 
cidata. In fact Ridley ^ actually reduces P. maculata to P. dis- 
ticha. I think, hovt^ever, that true Pinanga macidata of the Phil- 
ippines is distinguishable from the Malayan P. disticha by the 
leaves having a longer petiole and the blade being more deeply 
bilobed. The flowers and the fruit probably offer other diag- 
nostic characters, but I have not seen fertile specimens of the 
wild Philippine plant.

4. PINANGA ISABELENSIS Becc. sp. nov. 
Gracilis, caudice 2 ad 2.5 cm diametro. Frondium vaginis 
squamuloso-pubescentibus, segmentis aequidistantibus, utrinque 
8 vel 9 inter se remotis, elongato-ensiformibus et subfalcatis, 
acuminatissimis, 2- ad 4-costulatis, subtus glabris vel vix secus 
nervos papillosis; spadicis ramis paucis (5 vel 6) ; fructibus 
exacte distichis, anguste ovoideo-conicis, vel in dimidia inferiori 
parte latiusculis et supeme conico-attenuatis, 16 ad 18 mm 
longis, 6 mm latis; semine elongato, apice conico, fovea em- 
brionali obliqua; integumenti ramis vascularibus 3 vel 4, fere 
indivisis; perianthio fructifero cupulari truncate. 
Luzon, Isabela Province, Biocbian Bay, Bur. Sci. 10660 McGregor, in 
beach forest, about 50 meters from the sea. 
A slender plant, the stem 2 cm in diameter, with short inter- 
nodes (3 to 4 cm long) . The wood is very hard, and it is appa- 
rently a slow-growing plant, as the surface of the stem is 
covered with crustaceous lichens in its lower and older parts. 
Leaf-sheaths finely and softly tomentose. The only leaf seen 
by me is 90 cm long in the piniferous part; the petiole is 
20 cm long, slightly scurfy, or sprinkled with brown scales; the 
segments are subopposite, very few (6 or 7) and 8 to 9 cm apart 
on each side of the rachis ; two or three of the lowest segments 
are very narrow; the intermediate ones are elongate-ensiform,
