Ficus temburongensis C.C.Berg , sp. nov. — Fig. 4

Ficu albomaculata similis, ramuli floriferus tenuibus ad 3 m longis,fici receptaculo subgloboso,bracteis lateralibus brunnee hirtellis numerosus curvatis, pilosum internorum et in stylis absentia distincta. — Typus: Coode et al. 7957 (holo L; iso AAU), Brunei, Temburong, Batu Apoi, Selapon , 30 m, 30 Jan. 1994 .

Tree 5 m tall. Leafy twigs 2– 5 mm thick, predominantly white to brownish sericeous to subvillous and also with short whitish hairs, without nodal glands. Leaves spirally arranged, subcoriaceous to chartaceous, oblong, 9 – 22 by 2–7.5 cm, apex acuminate, base cuneate to rounded to narrowly truncate, margin entire white sericeous, upper surface white sericeous, glabrescent; lower surface white sericeous on the main veins and to white puberulous to subtomentose on the smaller veins; cystoliths present only beneath; lateral veins 6 –10 pairs, none of them furcate away from the margin, the basal pair up to 1/10–1/6 the length of the lamina, tertiary venation scalariform; glands absent; petiole 1–6 cm long, 1–2.5 mm thick, white to brownish sericeous, the epidermis flaking off; stipules c. 2 cm long, white appressed-puberulous, at the keel and the base white to brownish sericeous to subvillous, caducous. Figs on short slender branchlets on the branches (and trunk?) and on up to 3 m long stolons departing from the lower part of the trunk, subsessile, basal bracts 3 –4(– 5), 2 –5 mm long, brown subhispidulous, receptacle subglobose 1–1.2 cm diam, red-brown hirtellous, with numerous, ± curved brown-hairy lateral bracts; ostiole 5 –6 mm diam, with the bracts pointing upwards; internal hairs absent.

Additional specimen. Ridsdale PBU.189A (L), Indonesia, Kalimantan,

Tenah, Barito Ulu, 0 m, 25 May 1990.

Notes — 1. Ridsdale PBU.189 ( L) is a mixed collection with a separate ‘fruit collection’ containing material of F. cereicarpa , related to the label data; the part with leafy twigs and separate figs matching those of the type collection is to be indicated as Ridsdale PBU.189 A .

2. Attempts to trace duplicates of the type in the herbaria BRUN and K failed .

3. The new species can be keyed out in the key for Bornean stoloniflorous species constructed by Berg & Chantarasuwan (2007) by adding between lead 1 and 2:

2. Leafy twigs and main veins of the lamina densely white (to slightly brownish) sericeous; apex of the lamina acuminate........................... F. temburongensis

2. Leafy twigs and main veins of the lamina beneath predominantly brown hirtellous, if whitish, then short and sparse, or if yellowish, then the apex of the lamina caudate.......
