			<div type="discussion">The species epithet of this extraordinary new rattan refers to the shaggy appearance of its lacerate, fimbriate leaf sheath spines. The papery spines are numerous and apically truncate, giving the impression that they have been roughly trimmed with scissors. Although known from only four collections, the large distances between the three localities suggests that C. dasyacanthus is widespread, if not common, in the western half of New Guinea. Further collecting efforts in the lowlands of west New Guinea, especially in Merauke and Mimika Regencies in Papua Province, would very likely yield new records.</div>

			<head>SPECIMENS OF UNCERTAIN AFFINITY</head>
309
			<p>The following specimens cannot be readily assigned to species:</p>
310
			<p>Banka 2012 (Papua New Guinea, Morobe Province) – a remarkably slender, unarmed palm with subregularly arranged leaflets. At 9 m tall, the specimen is undoubtedly adult and yet its stem is a mere 5 mm in diameter. We tentatively link it to C. vitiensis, as opposed to C. aruensis, because moderately slender forms of C. vitiensis are known already, whereas C. aruensis is uniformly robust. The cirrus of Banka 2012 is too fine for the arrangement of the grapnel spines to be observed clearly. </p>
311
			<p>Kjaer 531 (Papua New Guinea, Western Province) – with truncate and irregularly lacerate sheath spines and leaflets grouped in pairs, this specimen has close affinities to C. dasyacanthus. However, the sheath spines are thick and rigid, rather than papery and flexible. This collection may be another undescribed species or alternatively may represent an additional dimension to the morphological variation of C. dasyacanthus. More material from the region is required.</p>
312
			<p>Whitmore BSIP 2362 (Solomon Islands, Santa Isabel) – a robust palm bearing spines of various sizes, the larger spines with somewhat swollen bases and forming whorls. The leaflets are regularly arranged and the cirrus grapnel spines organised in whorls. The specimen may represent a new record for C. pachypus in the Solomon Islands or perhaps a different dimension to C. vitiensis, but the material is too limitied for a judgement to be made.</p>
313
			<p>Zieck and Kumul NGF 36533 (Papua New Guinea, Gulf Province) – the leaflets of this rather poor specimen are irregularly grouped and the sheath spines are numerous, narrow and flexible. A few sheath spines are divided into two to four points. Its closest affinities may lie with C. vitiensis</p>
