HAMBALI Herbarium Bogoriense — LBN, Bogor, Indonesia ABSTRACT An illustrated description of Balanophora hansenii Hambali, spec, nov. is presented. The species belongs to sect. Dibalaniella. ABSTRAK Pertelaan bergambar jenis baru Balanophora hansenii Hambali disaji- kan. Jenis ini tergolong seksi Dibalaniella. In his monograph on the genus Balanophora J.R. & G. Foster (Dansk Bot. Arkiv 28: 1-189. 1972) Dr. Bertel Hansen recognized 15 species. However, as a by product of a recent mistletoe-hunting trip with Drs. John and Soejatmi Dransfield in Malaya, one more species is to be included in this genus. Balanophora hansenii Hambali, spec. nov. — Fig. 1. A ceteris speciebus sectionis Dibalaniellae tuberibus inflorescentias ferentibus cylindricis, inflorescentia foliis aggregatis occulata differt. HOLOTYPUS: Hambali s.n. (BO). Dioecious plants, dirty to bright coral red, with a pale yellow inflo- rescence. Tubers branched, elongate, those bearing inflorescences dis- tinctly cylindrical, 4—6 cm by 1.5 cm with apical part ca. 1 cm wide, surface fine granular, minutely puberulous, with scattered white stellate warts. Leaves 1.5—3.8 cm by 1.1—1.9 cm, appearing verticillate on a very short stem of 1 cm long, 3-merous, in 3—4 whorls, slightly cucullate, appressed to and completely concealing the inflorescence, forming a compact oval head, during anthesis rather loosely arranged; longitudinal nerves 5—8, visible only in wet translucent material, median nerves occasionally branched at the middle. Male inflorescence ca. 2 cm by 1.8 cm; flower — bearing bracts 2.5 mm by 4—5.5 mm, truncate, non flower — bearing bracts 3—4 mm by 3—4 mm, spathulate to acute. Flower 19—20, (3-), 4-, (5-) merous, zygomorphic, dimensions of basal flowers larger than those of the apical; pedicels ca. 2—7 mm; lateral _ 4 2 5 — 426 U E I N W A R D T I A [VOL. 9 3mm Balanophora hansenii Hambali. — a.

No. female plants were observed. This new species, named after Dr. Bertel Hansen in appreciation for his interesting monograph, belongs to the section Dibalaniella Tiegh., of which three other closely-related species, i.e. B. elongata Bl., B. papuana Schlecht. and B. lowii Hook.f., are already known. The compact head- like arrangement of the leaves which completely conceals the inflorescence, and the distinctly cylindrical inflorescence-bearing tubers are two features which make it easily distinguishable from the other members of this section. Despite the superficial verticillate appearance, the leaves are actually arranged in a subtle compact spiral. This new species was featured under the name of Balanophora papuana in Nature Malaysiana 3(1) : 24. 1978. MALAY PENINSULA. Selangor/Pahang border, Gunung Ulu Kali, dwarf forest on a ridge in the vicinity of Genting Highlands recreation resort, alt. ca. IT'OO' m, parasitic on the root of Pentaphylax euryoides Gardn. & Champ. (Pentaphy- lacaceae), 31 December 1977, Hambali s.n., preserved in spirit, provided with a colour transparency (BO). One inflorescence was at anthesis at the time of collecting (about noon). The flowers emitted a faint, disagreeable smell, reminiscent of that of Laurentia longiflora (L.) Peterm. I should like to express my warm gratitude to Drs. John and Soejatmi Dransfield, who enabled me to make the most of my stay in Malaya. My gratitude is also extended to my parents who helped finance the trip, to the Kadarsan family for their hospitality, and Sdr. M. Anwar for the drawing. I thank Dr. J. Dransfield further for preparing the latin diagnosis. CONTENTS Page Hsu AN KENG. A new interpretation of the compound strobilar structures of cordaites and conifers , 377 SOEJATMI DRANSFIELD.
