terminal discoid mammillate areola, bearing the remains of the small 
stigmas. Fruiting perianth not accrescent, but hardened, and with the 
apices of the petals spreading. 
Hab. Arfak Mts., Angi lakes, 2100-2400 m. ¢ 2. Fr. Dee. 5951. 
Without doubt rather elosely related to Kentia procera, from which it 
differs in having the uppermost leaflets truncate and premorse-toothed, and 
in the male flowers having larger anthers, as long as two-thirds of the 
entire flower. In K. procera the uppermost leaflets are bidentate at apex, 
and the anthers reach only to about the middle of the petals. The mature 
fruit of KA. Gibbsiana is probably more broadly ovate than that of 
KK. procera. 
K. Gibbsiana is one of the very few palms that belong to the true genus 
Kentia as understood by me in ‘ Webbia,’ vol. iv. (1913) 143.

armatis, ocrea magna, elongata, acuminata, chartacea, 50 em. et ultra longa, spinulis

spinulosa; segmento terminali profundissime bilobo; spadice ¢ foliis breviori,

Scandent, and of moderate size. Sheathed stem apparently 15-20 mm. 
in diam. Leaf-sheaths (in the small portion seen by me) closely armed with 
short small prickles, Ocrea extraordinarily large and long, as much as 
50 cm. in length, very gradually Jong-acuminate, slightly inflated, enfolding 
the younger part of the stem, covered with thin fuscous-furfuraceous scurf, 
chartaceous, exsuccous, rigid, later splitting longitudinally on the outer side 
and not dissolving into fibres, fugaciously furfuraceous outside and orna~- 
mented all over, and rather closely, with oblique, interrupted, slightly raised, 
spinuliferous lines or ridges. Leaf-sheath flagella slender and very long, 
armed, but not very regularly, with ternate or quinate claws, intermingled 
with smaller scattered prickles. Leaves non-cirriferous ; in one specimen 
about 1 m. long on the whole; the petiole alone 35 cm. long, almost 
biconvex, slightly prickly, and with obtuse margins; rhachis smooth, 
bifaced, with an acute salient angle above, and armed beneath, at first, with 
quinate and higher up with ternate claws. Leaflets very conspicuously 
approximate into very few distant groups (3 in the specimen at hand) 
with long vacant spaces of rhachis interposed ; in one specimen the leaflets 
are 7 on each side of the rhachis, of which 8 (4 on each side) form a 
basal group, and 7 (3 on each side with a deeply bilobed apical one) form 
the terminal group ; between these two main groups is another intermediate
