190 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [M. amicarum 
crowded in gentle spirals, at times somewhat irregularly; inside the spathes every 
pair of flowers is enveloped by a bracteole formed by two united together, thinly 
membranous, brown and provided on both sides with a dense faleate tuft of palea- 
eeous hairs; the female hermaphrodite flower has its bracteole membranous, two- 
keeled on the side of the male flower (which it embraces also) and hairy palea- 
ceous on the keels; the second bracteole of the female flower is almost entirely 
reduced to a tuft of hairs. The full grown buds of the female—hermaphrodite flower; 
just before their opening, project with the entire length of the corolla above the 
spathels, are oblong, very obtuse, very obsoletely trigonous, 8—8'5 mm. long, 3:54 mm. 
across ; the calyx is cyathiform, slightly tapering below, faintly striately veined, shortly 
3-lobed, the lobes rounded; the corolla is a little less than twice as long as the 
calyx, is deeply parted into three oblong cymbiform, coriaceous segments, and has a 
short, entire, campanulate base. The stamens form with their united bases a 
campanulate cup, connate with the base of the corolla, and very shortly free above 
itsthroat; in the ‘free part the filaments are elongate, thickish, with the apices 
truncate, but ending in a very minute introflexed apiculum, to which are attached 
the anthers a little above the middle of their dorsum. The anthers are elongate- 
elliptical, acute with parallel but somewhat irregular cells, 5—6 mm. long and 
deeply disjunct at the base. The. female—hermaphrodite flowers have the ovary 
ovoid, narrowing above to an elongate, gradually acuminate, rigid, trigonous and 
3-suleate style, which with its acute stigmas attains to the apices of the anthers 
which at the time of the authesis are filed with pollen (active?) and are 
identical with those of the male flowers. The male flowers differ from the female 
ones only in the absence of íhe ovary, which is represented by three very small 
bodies, resting on the bottom of the staminal cup. Fruit globose, pomiform, usually 
slightly broader than high, 8—9 cm. ‘in diameter, the base not hollowed, indeed 
slightly prominent, and obsoletely gibbous-costulate, broadly umbilicate and with a 
very small central conical mucro on the top; at times the entire periphery of the 
fruit is very obscurely 6-costulate longitudinally ; scales shiny in 24—28 vertical series, 
the largest slightly broader than long (15 mm. long, 17 mm. broad), rather 
suddenly contracted into a slightly produced, appressed, acute or bluntish point, 
convex, faintly concentrically striate across, deeply grooved along the middle, the 
grooves continuous on all the scales of the same vertical series, reddish or yellowish 
brown blending to a darker marginal line; the margins narrowly discoloured and very 
minutely erosely-toothed. Seed globose, 6'5 cm. in diameter (in one specimen); its 
integument thin (not fleshy) and very adherent all round, except in correspondence 
with the chalaza, where it is thick and corky (when dry) and penetrates into the 
upper cavity of the albumen; the cavity is large, orbicular, 2'5 cm. in diameter 
. and is slightly narrowed at the mouth ; at the base the seed has a small depres- 
sion corresponding to the place occupied by the embryo; the albumen is bony, 
white, homogenous, horse-shoe-shaped in vertical section, and has the walls 
18—20 mm. thick. The largest of Ledermann's fruits weighs"175 grammes and the 
nut alone 110 grammes. 
 HanBrrAT.—The specimens I have described, consisting of portions of the leaves, 
flowers and fruits, were collected by Dr. C. Ledermann on the 8th October, 1913, 
in Panape, in the Eastern Carolines at Naupon mal (Patapat), between 2—300 m.
