      Known only from Bukit Teraja and Ulu Ingei, on Bukit Batu Patam. Endemic to Brunei. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)B

      Discussion

      • Calamus maiadum occurs in kerangas forest developed on a ridge top on Bukit Teraja and in similar forest on a gentle slope on Bukit Batu Patam. This is a very distinctive species, belonging to the group of species that Furtado included in his section Platyspathus, and that are referred to in northern Borneo as "wi tulang" (see Dransfield 1990). This group includes C. myriacanthus, C. bacularis, C. sabalensis, C. acanthochlamys and C. paulii and the two species described here as new. C. maiadum is immediately distinguished from the rest by the extraordinary soft curved Appendix 193 whisker-like bristles that adorn the leaf sheath mouth and the primary inflorescence bracts. Though so distinctive in the field, once we had seen and collected it twice we searched for it on many subsequent occasions in Brunei but without success. The description is thus inevitably drawn from rather incomplete material. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)B

      Diagnosis

      • bracteis inflorescentiae Sectionem Platyspatham Furtado pertinens, a C. myriacantho et ceteris speciebus sectionis spinis vix trichomatiformibus curvatis egregie mollibus apice vaginae foliorum et bractearum inflorescentiae differt. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)B

      Etymology

      • The specific epithet (inspired by Beccari"s Pholidocarpus maiadum) is derived from a Bornean name, "maias", for the orang utan; the strange brown whisker-like bristles are reminiscent of the coarse long brown hair of the orang utan. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)B

Inflorescence, only pistillate known, branching to 2 orders, erect or arcuate, to 2 m long, with 4 partial inflorescences; prophyll elongate, ± tubular throughout, c. 80 cm long, 2 cm wide, armed distally with short horizontal dark brown flattened spines to 4 mm long, and abundant soft, flexible, ± reflexed dark red brown whiskerlike spines to 70 mm long, scattered floccose indumentum abundant between the spines; rachis bracts similar to the prophyll, similarly covered towards their tips with whisker-like bristles, these much shorter in the distalmost rachis bracts; partial inflorescence emerging at the mouth of the subtending bract, the basal to at least 30 cm long, the distal shorter and the apical to c. 23 cm; bracts on first order branch c. 11 × 4 mm, with truncate apex, unarmed but covered with abundant brown scales; mid inflorescence partial inflorescence bearing 11-12 strictly distichous rachillae on each side; rachillae 40-60 × 2.5 mm, rachilla bracts tubular with triangular limbs to 1 mm long, striate, with scattered very short dark brown spinules and scattered indumentum; involucrophore and involucre explanate, striate, not pedicellate; scar of sterile staminate flower c. 0.5 mm diam. Pistillate flower c. 4 × 3 mm, ± conical in outline; calyx to 3 mm long, striate, glabrous, tubular in the basal 2 mm, with three short triangular lobes; petals 3 × 1.5 mm, smooth; staminodes c. 1.1 × 0.2 mm; ovary c. 1.5 mm diam., tipped with non-scaly columnar style to 2 × 1.5 mm and three reflexed stigmas to 2 × 1 mm. Other parts unknown. (J. Dransfield & H. Beentje, The Palms of Madagascar. 1995)B

        Known only from two collections from the summit of G Pueh. Endemic. (J. Dransfield, The Rattans of Sarawak. 1992)D

        Discussion

        • C. poensis is a little known species occurring in low mossy forest on the summit of G Pueh. In 19811 searched for it but without success; it seems likely that the two collections were made on the summit of a higher peak elsewhere in the G Pueh Range. From herbarium material it seems to be close to C. marginatus but is immediately distinguished by the grouped leaflets. (J. Dransfield, The Rattans of Sarawak. 1992)D

        Etymology

        Description

        • Solitary (?) or clustered (?) rather slender rattan climbing to 5 m tall; stem without sheaths c. 8 mm diam., with to c. 15 mm diam., internodes short.

Flagellum apparently present. Leaves ecirrate to c. 80 cm long including the petiole to c. 16 cm; petiok armed with regular lateral spines to 30 mm long; leaflets c. 20 on each side of th( rachis, arranged in groups of 2 - 8, the apical c. 3 -4 leaflets on each side crowdei together and radiating, the leaflet bases slightly swollen, the longest leaflets 30 - 35: 1.8-2 cm, bristly along the midrib and margins, transverse veinlets conspicuous Inflorescences long, slender, with a terminal flagellum, to c. 2.3 m, with 4 very la partial inflorescences; male rachillae c. 2 - 2.5 cm long; female rachillae to c. 5 ci long.
