KOSTERMANS Herbarium Bogoriense, Bogor, Indonesia ABSTRACT Two species of Lindera (Lauraceae), one from Annam (Lindera spicata, spec, nov.) and one from Sulawesi, Indonesia (Lindera racemiflora spec, nov.) with an unusual kind of inflorescence are described. Their genetic identity is not absolutely sure, as mature flowers are lacking. Ultimately they may belong to an undescribed genus. A B S T R A K Dua jenis Lindera (Lauraceae), salah satu dari Annam (Lindera spicata, spec, nov.) dan yang lain dari Sulawesi, Indonesia (Lindera racemiflora,spec, nov.) mempunyai perbungaan yang tidak umum, telah dipertelakan. Iden- titas marganya tidak meyakinkan karena tidak adanya bunga yang masak. Diduga keduanya termasuk kedalam marga yang belum pernah dipertela- kan. The two species described below are from ultrabasic and granitic soils and show a remarkable likeness in their inflorescences, one being spicate the other racemoid. Unluckily they have been collected in a very young flower-bud stage and hence their generic identity is not-even absolutely sure. There is a possibility, that both pertain to an undescribed genus. Lindera spicata Kosterm., spec. nov. — Fig. 1 Arbor parva ramulis cylindricis strietis dense minutissime puberulis, foliis alternantibus triplinerviis chartaceis ellipticis conspicue acuminatis, basi cuneatis, supra opacis nerviis principalibus filiformis impressis, subtus gri- seis, obscure minute reticulatis, sat dense ferrugineo-puberulis, inflorescentiis axillaribus, spiciformis dense minutissime puberulis, floribus sessilibus pilo- sis, bracteolis basalibus. — TYPUS : Poilane 32710 (L holo, P) 33 24 REINWARDTIA [Vol. 11 Tree 5 m tall, diam. 15 cm. Twigs smooth, hard, stiff, cylindrical. Leaves scattered, chartaceous to subcoriaceous, triplinerved, elliptic, 3 x 5 - 2.5 x 8 cm, conspicuously acuminate (acumen up to 1 cm), base cuneate; above dull, the three main nerves filiform, impressed, the surface densely microscopically reticulate-areolate; below pale, densely minutely reticulate, rusty-puberulous (denser on the nerves), hairs erect, slightly curly; the two basal lateral nerves slender, prominent, reaching the base of the acumen, connected by very thin camptodromous secondary veins; the lateral secun- dary veins erect-patent, near the margin arcuately ascendent. Petiole very slender ca. 1 cm. Spikes axillary, densely minutely puberulous (hairs erect, slightly curly), up to 3 cm long. Bud pilose, sessile, subtended by a minute, acute bracteole. DISTRIBUTION : Annam, only known from the type locality. The flower (or inflorescence) buds are too immature to be analyzed. I believe to have seen 2-celled anthers. ANNAM, Prov.
