Abstract

1. In the following pages an account of the genus Viburnum in Malaysia is presented. 2. The distribution of its species is briefly discussed and a map relating to it added. 3. The main part of the present paper consists of keys to the sections and species, followed by a systematic treatment of the 16 species admitted for the region. 4. Three new subsections are proposed, viz. Viburnum subsect. Punctata Kern,subsect. Sambucina Kern, and subsect. Lutescentia Kern. Viburnum subseries Coriacea Maxim, is reduced to the rank of a subsection. 5. Three species and two varieties are described as new, viz. Viburnum amplificatum Kern, V. clemensae Kern, V. hispidulum Kern, V. coriaceum, var. longiflorutn Kern, and V. sambucinum var. subglabrum Kern. 6. The following species are reduced to the rank of varieties: Viburnum floribundum Merr. has become V. luzonicum var. floribundum (Merr.) Kern, and V. sinuatum Merr. has become V. luzonicum var. sinuatum (Merr.) Kern. 7. The following reductions'to synonymy are made: Viburnum longistamineum Ridl. to V. sambucinum- var. subglabrum Kern; V. sumatranum Miq., V.villosum Ridl., and V. inopinatum Craib all to V. sambucinum var. tovientosum Hallier f.;V. forbesii Fawc. partly to V. sambucimim Bl., partly to V. coriaceum BL; and V. zippelii Miq. to V. japonicum (Thunb.) Spr. 8. Emended descriptions of Viburnum beccarii Gamble and of V. junghuhnii Miq. are given.

Abstract

This is the first paper of a series, in which preparatory to a more comprehensive treatment for "Flora Malesiana," some noteworthy Malaysian Cyperaceae will be dealt with. It is based on the material of this family in the Herbaria at Bogor (BO), Leiden (L), and Singapore (S).My sincere thanks are extended to the Directors of these institutions for giving me the opportunity to study their rich collections.In 1935—36 Kiikenthal's excellent monograph on the genus Cyperus in Engler's "Pflanzenreich" appeared.Unfortunately that author revised only a few specimens of the herbaria already mentioned,so that the basis for the distribution of the genus in Malaysia, as given in his invaluable work, compares unfavourably with that of the species of other regions.Kiikenthal's delimitation of the genus is readily accepted; in general his arrangement of the species is also followed, although I cannot agree with Kiikenthal's assertion that his system should be in close accordance with the genetic development of the genus.On the whole only the synonymy important for the Malaysian region is given below. For a more complete account the reader is referred to Kiikenthal's monograph, in which of course the literature of merely regional interest could not always be fully considered.The accompanying plates are part of a series, drawn under mysupervision by two of the draughtsmen of Herbarium Bogoriense, Sukirno and Md. Anwar.

Abstract

In "Reinwardtia" (1: 157. 1951) I published a new species of Viburnum from Mount Kinabalu, Borneo, under the name of V. clemensae.The description was drawn up after fruiting specimens in the Herbarium of the Arnold Arboretum. Unfortunately flowers were wanting in the specimens available.Some time ago Dr. A. J. G. H. Kostermans came across much more complete material among the indeterminata of the Bogor Herbarium, profusely flowering as well as fruiting. This enables the amplification of the description.
