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

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

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.

Abstract

The difficulties encountered in this group could not be solved by the application of this key to the numerous specimens I could study. In the type specimen of Scirpus pakapakensis Stapf from Borneo, Mt. Kinabalu, the stems are not trigonous. Although in Thwaites CP306 (type collection of Scirpus subcapitatus) the mucros of the leaf-sheaths and of the outermost glume are practically smooth, they are scaberulous in several Indian specimens otherwise quite agreeing with the type collection. In some specimens from Mt. Kinabalu the stems are slightly scaberulous at the top; for the rest they agree very well with the type of Scirpus clarkei Stapf.

Abstract

Since 1884 the name Cyperus zollingeri Steud. has been misapplied to a common tropical species, the correct name of which is C. tenuieulrnis Boeck.It appears that C.rubroviridis Chermez.(1919) and C. ramosiiKiikenth.(1925) are synonymous with C. zollingeri Steud. (1855).Cyperus leucoeephalus Retz, and C. pulehellus R. Br. are treated as specifically distinct.The Philippine record of C.leucoeephalus is referred to C. pulehellus.A tentative arrangement of the Malaysian material of the polymorphous Cyperus sanguinolentus Vahl is given.Mariscus maritimus Miq. is reduced to Cyperus dubius Rottb.,C. pulcherrimus f. retiglwmis Valck. Sur. to the species.The previous Malaysian records of Cyperus stenostachyus Benth.and C. polystachyos 1. longispiculatus Valck. Sur. are erroneous. A survey of the distribution of some Malaysian species is given.The following new combinations are made: Cyperus trialatus (Boeck.) Kern; C. sanguinolentus ssp. melanocephahis (Miq.) Kern, ssp.cyrtostachys (Miq.) Kern, and ssp. teijsmannii (Miq.) Kern.

Abstract

This supplement contains an account of a rather large number of Thailand specimens, collected by A. F. G. Kerr, Marcan, Put, and some others, kindly sent on loan to me by the Keeper of the British Museum (Nat. Hist.), Botany Department, Mr J. E. Dandy. A few additions from the Rijksherbaiium, Leyden, marked (L) and Copenhagen, marked (C), & c. are also added. Three species (nos 175 - 177) are new for Thailand. Among them Lipocarplia pygmaea is very remarkable, as it was so far only known from a recent collection by Van Steenis in Cambodia. Probably this dwarfish sedge was often overlooked. From the species recorded for Thailand as doubtful (Kern, I.e. 79) the record of 1. Cyperus eleusinoides Kunth has appeared to be 95. Cyperus nutans Vahl. Furthermore, the record of 7. Mariscus clarkei Turr. could be reduced to a variety of Cyperus cyperoides (L.) O. K. The numbers of the species are those used in the first paper. An index to collectors' numbers is given at the end.
