128 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [C. Tapa. 
suborbicular or irregular, very shallowly concave; areola of the neuter flower puncti- 
form, more or less swollen or tuberculiform, Female flowers small, 8:5 mm. long, 
elongate-conical from a flattish base, i’ mm. broad, acuminate, glabrous; the calyx 
strongly striately veined and with 3 short acuminate teeth; the segments of the 
corolla lanceolate-acuminate, slightly longer than the calyx. Neuter flowers very 
similar to the female ones, and about as long as these but much thinner. Fruiting 
perianth pedicelliform, Fruit small, ovoid-elliptical or subobovoid, obtusely apiculate, 
8 mm. long, 5 mm. broad (when not quite mature); scales arranged in 21 longi. 
tudinal lines, glossy, light green all over or, with a reddish intramarginal line: they 
have a narrow, scarious, finely erose margin and are rather deeply grooved along 
the centre: the apex is slightly produced and bluntish. Seed not seen when quite 
mature. ; 
Hasitat.—The Philippines. Elmer has collected in Mindanao, District of 
Davao, two numbers, showing slight differences among them. That which may be 
considered as the type, No. 10541, was collected in dense woods in May 1909, at 
1300 m. above the sea level, south of the Sibulan river and to it are assigned the 
native names *'Lessee" or rather ‘“ Rassee.” The other, No. 10618, was collected 
also in May 1909 at 1800 im. in the forests on Mount Caliean and bears the 
native name “ Sambonotan,” à 
OssrRvaTIONS,— Owing to its elongate lanceolate leaflets, green above and white 
underneath, it may at first be mistaken for C. discolor; it is, however, quite distinct 
from that by its non-flagelliferous spadix and quite different spathes. Its affinities, 
however, seem greater with the species of the group of C. siphonospathus, but it is 
distinguishable also from these by; its non-sheathing spathes, spread open after the 
anthesis, as in the species of the QC, platyspathus group. Elmer’s No. 10618 slightly 
differs from No. 10541 in the leaflets, which are sometimes bristly on some of the 
secondary nerves, and in the slightly more rounded fruit !with  concolorous scales, 
The leaf-cirrus described above having the very peculiar filiform rudimentary leaflets 
belongs to No. 10618. E à;

Description.—Scandent and slender. Sheathed stem 10-14 mm. in diameter. Leaf- 
sheaths strongly  gibbous-plicate above, obliquely truncate at the mouth, thickish, 
yet of a relatively soft texture, and shrinking longitudinally in drying, dull and 
glabrous, rather powerfully armed with rather large and robust, scattered, horizontal 
spines, which have a swollen base more or less concave below; the largest spines are 
8-10 mm. long, but several are smaller, and, at times, are reduced to simple non. 
pungent tubercles. ^ Ocrea membranous, short (10-lómm. long), glabrous, axill ary,
