P. geminiflorus. PLECTOCOMIOPSIS, 53 
of the lowest, has the main axis recurved, is 45 em. long, and carries numerous 
(18). dependent flower-bearing branchlets, 20—30 cm. long, including a rather 
slender elongate pedicellar part, which is sheathed by vacuous or non-flower- 
bearing spathels, otherwise the flower-bearing branches ‘are similar to those of the 
type. and have the spathels covered with fulvous appressed hairs as usual, but 
are more acuminate; the involucre is shallowly concave, trigonous, finely ciliate on 
the margins; the bracteoles are also acute and ciliate. Female flowers two or 
occasionally three at each spathel, apparently subhermaphrodite, very broadly ovoid 
and obtusely trigonous, bluntish, about 6 mm. long, 5 mm. broad; the calyx is 
cupular, of a thick structure, and has a subcallous broad base, is broadly 3-toothed, 
slightly hairy-} apillose, but later glabrous; the corolla is twice as long as the 
calyx. parted down below the middle into 3 pergamentaceous, concave, ovoid, acute 
segments, covered outside with very appressed very thin hyaline scales. Staminal 
urceolum thickish, almost entirely free from the corolla, only a little shorter than 
it and enclosing the pistil; the mouth of the tube is divided into 6 short trian- 
gular teeth, representing the filaments, curved: inside; each tooth ‘bears an almost 
normally developed, broadly ovate, subdidymous, anther ; the young ovary is oblong 
and bears above a ring of few large imbrieating scales ; stigmas thiekish, broadly 
linear, connivent, obtuse. Fruit unknown. HN 
Hanrrar.—The type ‘specimen representing this apparently rather distinct 
variety bears almost fully developed female flowers and was collected by Dr. 
Winkler at Hayup in S.-W. Borneo (No. 2401 in the Breslau and Beccari 
Herbaria). Specimens from young plants also referable to this variety are Heyne’s 
Nos. 20 dis and 11 (Herb. Bogor. and Becc.) from Bandjermassin, and most pro- 
bly. also Beco. P. B. No. 2079, the type of C. triqueter, from Mt. Mattang in 
Sarawak. f 
Osservations.—It differs from the plant growing in the Malayan Peninsula, in 
the partial inflorescences having far more numerous spikes, and furnished with a 
rather elongate pedicellar part, and especially in the indumentum covering the 
corolla, which is formed by small flattened pellucid appressed scales, and not by 
thickish hairs. Heyne’s sterile specimens No. 20 bis from Bandjermassin are evi- 
dently conspecific with Winkler's_ No. 2401, but belong to younger plants ; they 
have trigonous, densely prickly leaf-sheaths, about 9 em. in diameter, with rather 
obtuse angles ; the naked stem however is rather sharply trigonous ; the petiole is 
rather elongate and trigonous. - 
Other specimens from Bandjermassin (Herb. Bogor. No. 20) which I consider 
as belonging to stil younger plants than the foregoing, have slender, acutely 
trigonous, leaf-sheaths with the sides only 8—12 mm. wide, and the angles very 
slightly prickly or almost smooth; at the mouth the sheaths have on the. side 
opposite to the petiole a ligula somewhat elongate and perishable; the petiole is 
rather elongate and trigonous ; the pinniferous part has very few leaflets, and ends 
in a slender rudimentary cirrus; the leaflets have no bristles on the mid-costa, and 
are provided with 3—4 secondary nerves on each side of it. Apparently the young 
plants of this Plectomiopsis are much less prickly than the adult.
